ABSTRACT

RESUMEN: Comparar mediante una revisión sistemática los resultados clínicos de los procedimientos de cirugía plástica periodontal/periimplantar (CP) con injerto de tejido blando autógeno (ITB) obtenido del área lateral del paladar (ALP) versus del área de la tuberosidad (AT). Se realizó una búsqueda electrónica de ensayos clínicos en la base de datos Medline/Pubmed, Cochrane y las revistas de Periodoncia e Implantes de mayor impacto según la Web of Science, para hallar artículos publicados hasta abril del 2020. Se valoró el riesgo de sesgo de los artículos añadidos según el manual Cochrane Versión 5.1.0 para ensayos clínicos aleatorizados y la escala Newcastle-Ottawa para ensayos clínicos controlados. De una muestra inicial de 930 artículos, cuatro ensayos clínicos (tres aleatorizados) fueron incluidos en el presente estudio, donde se realizaron un total de 87 CP alrededor de piezas e implantes dentales, de las cuales 42 cirugías fueron realizadas con ITB del ALP y 45 cirugías con ITB del AT, se evaluó los resultados desde las 8 semanas hasta los 12 meses. No se hallaron diferencias estadísticamente significativas en los resultados clínicos entre ambos grupos, se mejoró el fenotipo gingival en la zona receptora para el grupo que obtuvo el ITB del AT y el nivel del dolor del sitio donador del AT fue menor en las dos primeras semanas que el sitio donante del ALP. Los estudios incluidos manifestaron un bajo riesgo de sesgo en promedio. Ambas áreas donantes de injerto de tejido blando proporcionan resultados clínicos similares, el injerto del área de la tuberosidad mejora el fenotipo gingival de la zona receptora y reduce el dolor post operatorio en las primeras semanas del sitio donador.


ABSTRACT: The objective of the study was to compare, through a systematic review, the clinical results of periodontal / peri-implant plastic surgery (CP) procedures with autogenous soft tissue graft (ITB) obtained from the lateral palate area (ALP) versus the tuberosity area (AT). We conducted an electronic search of clinical trials in the Medline/Pubmed, Cochrane database and the journals of Periodontics and Implants with the greatest impact according to the Web of Science, to find articles published until April 2020. The risk of bias of the articles added was assessed according to the Cochrane Manual Version 5.1.0 for randomized clinical trials and the Newcastle-Ottawa scale for controlled clinical trials. From the initial sample of 930 articles, four clinical trials were included (three randomized) in the present study, where a total of 87 PC were performed around dental pieces and implants, of which 42 surgeries were performed with ITB of the ALP and 45 surgeries with ITB of the AT, the results were evaluated from the 8 weeks to 12 months. No statistically significant differences were found in the clinical results between the two groups, the gingival phenotype in the receiving area was improved for the group that obtained the ITB of the AT and the level of pain at the donor site was lower in the first two weeks than the ALP donor site. The studies showed a lowrisk of bias on average. Both soft tissue graft donor areas provide similar clinical results, grafting the tuberosity area improves the gingival phenotype of the recipient area and reduces post-operative pain of the donor site in the first few weeks.

ABSTRACT

Abstract: This multicenter study aimed to identify the different implant- and patient-related risk factors for long-term short dental implant success. Through a retrospective chart review of three centers, patient information regarding demographic variables, smoking habits, history of periodontitis, systemic diseases, and medications in addition to the parameters for short implant placement including implant manufacturer, design, anatomical location, diameter and length, and type of placement was collected. For statistical analysis, univariate regression models were used at the implant and patient levels. A total of 460 short implants placed in 199 patients followed up for up to 9 years were reviewed. Survival rates of the short implants were 95.86% and 92.96% and success rates were 90% and 83.41% for implant- and patient-based analysis, respectively. Peri-implantitis was reported as the primary cause of short dental implant failure (34/46, 73.91%). Univariate regression models revealed that female sex was strongly related to short implant success. In addition, smoking and history of periodontitis were found to have a significant negative influence on short implant success at the implant and patient levels. Taken together, these results support the use of short implants as a predictable longterm treatment option; however, smoking and history of periodontitis are suggested to be the potential risk factors for short implant success. Therefore, clinicians need to assess these potential risk factors and make treatment decisions accordingly.

ABSTRACT

RESUMEN: El objetivo de esta investigación fue analizar la etiología de las pérdidas dentales en pacientes rehabilitados con prótesis sobre implantes. Se realizó un estudio transversal con informaciones de 93 pacientes de una clínica privada que recibieron tratamiento con implantes en el período de 2000 a 2009. Los datos fueron recolectados a través de las fichas clínicas, documentaciones radiográficas y fotografías de los casos clínicos. Se levantaron datos sobre género, edad, nivel de escolaridad, hábito de fumar, tipo de diente extraído y razón de la extracción. Los resultados mostraron que la razón periodontal fue el principal motivo de las pérdidas dentales, representando el 24,7 %, seguida por las fracturas radiculares con pines metálicos (23,7 %) y caries secundarias (15,1 %). En los pacientes menores de 40 años, los traumatismos dentales y las fracturas radiculares con pino fueron responsables de la mayoría de las pérdidas. Las razones de las pérdidas dentales mostraron significancia estadística con la variable edad (p<0,05). El género, el hábito de fumar y el grado de escolaridad no mostraron asociación significativa (p>0,05) con las razones de las pérdidas dentales.


ABSTRACT: The aim of this study was to analyze the etiology of tooth loss in patients rehabilitated with dental implants. Was conducted a cross-sectional study with data from 93 patients from a private clinic who were treated with implants from the year 2000 until 2009. Data were collected through medical records, radiographic documentation and photographs of clinical cases. Data on sex, age, education level, smoking habits, teeth loss localization and extraction ratio were analyzed. The results showed that periodontal disease was the main reason for tooth loss, accounting for 24.7 %, followed by root fractures with posts (23.7 %) and secondary caries (15.1 %). In patients below 40 years, dental trauma and root fractures were responsible for most of the losses. The reasons for tooth loss showed statistical significance with the age (p<0.05). Sex, smoking habits and education showed no significant association (p>0.05) with the reasons of the tooth loss.

ABSTRACT

Abstract The aim of this study was to conduct a systematic review and meta-analysis to assess the clinical outcomes of dental implants placed in previously early and late implant failed sites. An electronic literature search was conducted in several databases for articles published up to February 2018. Human clinical trials that received at least one implant in a previously failed site were included. Hence, the PICO question that was aimed to be addressed was: Do patients undergoing implant replacement (second and third attempts) in previous failed sites have survival rates similar to implants placed at first attempts? A random effects model was used to calculate survival weighted means and corresponding 95% Confidence Intervals (CI) among studies. Eleven studies of low to moderate methodological quality were included in this review. Implants placed in sites with history of one and two implant failures had a weighted survival rate (SR) of 88.7% (95%CI 81.7-93.3) and 67.1% (95%CI 51.1-79.9), respectively. Implants placed in sites with a previous early failure revealed a weighted SR of 91.8% (95%CI 85.1-95.6). First implants presented higher SR than implants placed in sites with one or two previous implant failures. In contrast, implants placed in sites with one and two implant failures had similar SR. Within its limitations, this review suggests that replacement implants have moderate SR. Larger prospective studies with well-defined criteria for early and late implant failure are necessary to confirm and expand on these results.

ABSTRACT

Objetivo: avaliar retrospectivamente a taxa de sucesso de implantes e biomateriais após o levantamento do seio maxilar. Material e métodos: foram utilizados prontuários de pacientes tratados entre 1998 e 2014, incluídos os que possuíam rebordo maxilar com altura menor do que 5 mm. Todos os procedimentos de enxertia foram realizados com instalação de implante de forma mediata e acesso ao seio maxilar pela janela óssea lateral, colocação do biomaterial, membrana e sutura. Resultados: foram analisados 79 pacientes, tendo sido utilizados dois biomateriais. O tempo de reavaliação variou de seis meses a dez anos. Nos dados de altura óssea radiográfica antes e depois do procedimento (70 implantes, 36 pacientes), houve um aumento médio de altura na região do seio maxilar com o Bio-Oss de 17,23 mm e com o Orthogen de 13,12 mm (p < 0,05), sendo a média geral de 15,17 mm. Na relação sobrevida do implante e enxerto utilizado (92 implantes, 43 pacientes), os valores foram de 96,8% (autógeno) e 98,3% (autógeno + biomaterial). Conclusão: os resultados permitiram concluir que tanto os enxertos autógenos como os biomateriais são alternativas viáveis para os seios maxilares com grande pneumatização.


Objective: to retrospectively evaluate the success rate of implants and biomaterials after maxillary sinus lift. Material and methods: records of patients treated between 1998 and 2014 were used, including those with maxillary ridge height less than 5 mm. All grafting procedures were performed with implant placement and access to the maxillary sinus through the lateral bony window, placement of the biomaterial, membrane and suture. Results: 79 patients were analyzed and two biomaterials were used. The follow-up period ranged from six months to ten years. In the radiographic bone height data before and after the procedure (70 implants, 36 patients), there was a mean increase in height in the maxillary sinus region with the Bio-Oss of 17.23 mm and with the Orthogen of 13.12 mm (p < 0.05), the overall mean being 15.17 mm. Regarding implant and graft survival (92 implants, 43 patients), the values were 96.8% (autogenous) and 98.3% (autogenous + biomaterial). Conclusion: both autogenous grafts and biomaterials are viable alternatives for the maxillary sinuses with great pneumatization.

ABSTRACT

Nas últimas décadas houve um aumento considerável na utilização dos implantes metálicos para aplicações na área da ortopedia e odontologia, por isso as pesquisas têm como foco estudar os mecanismos biológicos de interação osso-implante. A nanotopografia de superfície de implantes osseointegráveis apresenta efeito direto sobre a resposta biológica óssea. No entanto a maneira como afeta a osseointegração in vivo ainda não está totalmente elucidada. O objetivo neste estudo foi comparar in vivo a influência da superfície em nanoescala (nano) confeccionada em implantes de titânio comercialmente puro (Ticp), comparado-a a superfície lisa (controle) em modelo experimental de camundongos osterix-mcherry (Osx-mcherry), os quais expressam proteína fluorescente concomitante com a expressão do gene osterix (Osx). Os animais receberam implantes de superfície lisa no fêmur direito e com nanoescala no fêmur esquerdo. Após diferentes períodos de eutanásia baseados na metodologia empregada foram realizados nas peças e nas células os seguintes testes biológicos: microscopia eletrônica de varredura (MEV) para avaliação da adesão celular e da superfície do implante; histologia e nanotomografia (nanoCT) para observação e quantificação de osso neoformado na interface osso/implante; citometria de fluxo para quantificação de células marcadas pelo gene osterix; PCR em tempo real (qPCR) para avaliação da expressão gênica; coloração fosfatase ácida resistente ao tartarato (TRAP) para contagem de osteoclastos. Nossos resultados mostraram que a maioria dos genes estudados estavam superexpressos nas amostras com superfície em nanoescala sendo que alguns deles apresentaram diferenças estatísticas (Teste t, p < 0.05), tais como: Osx (osterix), Alp (fosfatase alcalina), Prx1(homeobox relacionado emparelhado -1), Dmp1 (Dolicol-fosfatase mannosiltransferase subunidade 1), Bsp (sialoproteína óssea) e Ocn (osteocalcina). Os testes estatísticos ANOVA two way seguido do Teste de Tukey quando necessário, foram utilizados para os demais experimentos e o nível de significância foi estabelecido em p < 0.05. Diferenças estatísticas foram encontradas para o nanoCT e histologia entre as superfícies e períodos avaliados e os melhores resultados foram observados para a nanoescala. A coloração TRAP também mostrou diferenças estatísticas entre as superfícies e períodos estudados, com a superfície lisa mostrando melhores resultados aos 3 dias e a nano aos 5 e 7 dias. Não houve diferença estatística para a citometria de fluxo, porém a superfície em nanoescala mostrou melhores resultados que a lisa em todos os períodos analisados. Concluímos que a superfície em nanoescala possui propriedades osteocondutivas e favorece os eventos biológicos que ocorrem na superfície do implante melhorando o processo de osseointegração(AU)


In the last decades there has been a considerable increase in the use of metal implants for applications in the area of orthopedics and dentistry, so the researches are focused on studying the biological mechanisms of bone-implant interaction. Surface nanotopography of osseointegrated implants has a direct effect on the biological response of bone. However the way it affects osseointegration in vivo is not yet fully elucidated. The aim of this study was to compare the in vivo influence of the nanoscale surface (nano) made on implants of commercially pure titanium (Ticp) with the smooth surface (control), using an experimental model of osterix-mcherry mice (Osx-mcherry), which express fluorescent protein concomitant with osterix gene expression (Osx). The animals received implants with smooth surface in the right femur and nanoscale in the left femur. After different periods of euthanasia based on the methodology used, biological tests were performed in the femur and cells: scanning electron microscopy (SEM) for evaluation of cell adhesion and implant surface; histology and nanotomography (NanoCT) for observation and quantification of neoformed bone at implant interface; flow cytometry for quantification of cells marked by the osterix gene; Real-time PCR (qRT-PCR) for gene expression evaluation; tartrate resistant acid phosphatase staining (TRAP) for osteoclast counts. Our results showed that most genes studied were overexpressed in the nanoscale surface and some of which presented statistical differences(t Test, p <0.05), such as: Osx (osterix), Alp (alkaline phosphatase), Prx1 (related paired homeobox), Dmp1 (Dolicol-phosphatase mannosyltransferase subunit 1), Bsp (bone sialoprotein) and Ocn (osteocalcin). The two-way ANOVA statistical test followed by the Tukey test when necessary were used for the other experiments and the level of significance was set at p <0.05. Statistical differences were found for the nanoCT and histology between surface and periods evaluated and the best results were observed for the nanoscale. The TRAP staining also showed statistical differences between the surfaces and periods studied, with the smooth surface showing better results at 3 days and nano at 5 and 7 days. There was no statistical difference for flow cytometry, but the nanoscale surface showed better results than the smooth surface in all analyzed periods. We conclude that the nanoscale surface has osteoconductive properties and improves the biological events that occur on implants surface improving the osseointegration process(AU)

ABSTRACT

Objetivo: avaliar retrospectivamente as características dos implantes colocados no curso de especialização do Centro Universitário Ingá (Uningá). Material e métodos: os prontuários dos pacientes que realizaram tratamento entre 2005 e 2014 na Uningá foram analisados quanto à saúde sistêmica, sexo, idade, local de colocação, uso de enxertos, diâmetro e comprimento dos implantes, e complicações. Resultados: neste centro, 108 pacientes receberam 307 implantes de quatro marcas comerciais diferentes (154 na maxila e 160 na mandíbula). Os implantes foram instalados mais em mulheres (67,6%), principalmente na região posterior (76,7%), tanto de maxila (49%) quanto de mandíbula (51%), com o uso de enxertos ósseos em cerca de 20% dos casos da maxila e somente 1% dos casos de mandíbula. Além disso, ainda são realizados muitos implantes longos (38,6% > 13 mm), de diâmetro regular (83,6% entre 3,75 mm e 4 mm) e com plataforma do tipo hexágono externo (97,7%). Conclusão: no local pesquisado, ainda são instalados muitos implantes na região posterior, longos e de diâmetro regular, com plataforma do tipo hexágono externo. Além disso, os enxertos ósseos são usados em um em cada dez casos de implantes, principalmente na maxila.


Objective: to retrospectively evaluate the characteristics of implants placed in the specialization course of the Inga University Center (Uningá). Material and methods: the medical records of patients who underwent treatment between 2005 and 2014 at Uningá were analyzed for systemic health, gender, age, area of installation, use of grafts, diameter and length of the implants and complications. Results: in this center, 108 patients received 307 implants (four different brands, 154 in maxilla and 160 in mandible). The implants were installed more frequently in women (67.6%), mainly in the posterior region (76.7%), in both maxilla (49%) and mandible (51%), with the use of bone grafts in 20% of maxillary cases and only 1% of cases in mandible. The prevalence of long (38.6%, 13 mm), regular diameter (83.6% between 3.75 mm and 4 mm), and external hex implants (97.7%) was great. Conclusion: at the Uningá, many implants in the posterior region, long and of regular diameter with external hexagonal platform are still installed. Moreover, bone grafts are used in 1 of each 10 cases of implants, mainly in th e maxilla.

ABSTRACT

A reabilitação com implantes tem como desafio as limitações de quantidade e qualidade óssea, sendo necessárias técnicas cirúrgicas de enxerto ósseo, permitindo a instalação dos implantes convencionais. Para pacientes que preferem opções menos complexas e traumáticas, os implantes curtos são uma opção de tratamento menos invasiva e com boa previsibilidade. Porém, para o seu melhor desempenho, princípios biomecânicos devem ser empregados, como utilização de mesa oclusal reduzida, ferulização de implantes, conexão interna do tipo Cone Morse e plataforma Switching. O objetivo desse trabalho foi relatar um caso clínico de uma paciente que descartou a cirurgia de levantamento de seio maxilar, sendo então proposto o tratamento com a utilização de implante curto do tipo Cone Morse, em que foi realizado o planejamento reverso e o uso de princípios biomecânicos.


Rehabilitation with implants is challenged by bone quantity and quality limitations, being necessary surgical techniques for bone grafting that allow conventional implants installation. for patients who prefer less complex and traumatic options, short implants are a less invasive treatment option and has good predictability. however, for best performance, biomechanical principles should be used, such as use of reduced occlusal table, splinting implants, internal connection of the Cone Morse type and Switching platform. The aim of this study was to report a case of a patient who dismissed the maxillary sinus lifting surgery, so the treatment proposed was the use of short implant Cone Morse type, in which reverse planning was done with the use of biomechanics principles.

ABSTRACT

Objetivo: determinar a ocorrência de insucessos conforme o tempo de carregamento em implantes dentários de estágio único. Material e métodos: neste estudo retrospectivo com série de casos, após aplicação dos critérios de inclusão e exclusão, um banco de dados foi utilizado para coleta de desfechos clínicos (queixas subjetivas, infecção com supuração, mobilidade, profundidade de sondagem, sangramento gengival, e recessão gengival) e radiográficos (perda óssea anual). O tempo de carga foi dividido em G1(< 1 ano de carga), G2 (≥ 1 e < 5 anos de carga) e G3 (≥ 5 anos de carga). Análises bivariadas, de máxima verossimilhança, de regressão logística binária e OR foram aplicadas (nível de significância 5%). Resultados: 245 implantes cone-morse tissue level e bone level (G1=48, G2=103, G3=94; insucesso geral = 36,73%) foram avaliados em 111 indivíduos. O insucesso dos implantes foi maior em G1 (qui-quadrado = p < 0,001) do que no G2 e G3. A chance de perda de implantes no G1 (OR = 9,8) foi maior (p < 0,001) comparada ao G2 e G3 (sem diferenças estatísticas). Em geral, a radiolucência, o sangramento à sondagem, profundidade > 5 mm, e a perda óssea anual peri-implantar mostraram signifi cância estatística (qui-quadrado, p ≤ 0,001). Entretanto, apenas o sangramento (p < 0,001) e a perda óssea (p=0,014) mostraram significância na comparação entre grupos. Conclusão: a taxa de insucessos em implantes de estágio único conexão cone-morse foi maior no primeiro ano de carregamento.


Objective: to determine the failure rates of one-stage morse cone dental implants according to loading time periods. Material and Methods: in this retrospective case series study, after inclusion and exclusion criteria, a database was screened to collect clinical (subjective complaints, infection with suppuration, mobility, probing depth, gingival bleeding, and gingival recession) and radiographic (annual bone loss) outcomes. The loading time was divided into G1 (<1 year), G2 (≥ 1 and <5 years) and G3 (≥ 5 years). Bivariate analysis, maximum likelihood, and the binary logistic regression with OR were applied (5% significance level). Results: 245 morse cone implants (tissue and bone level types; G1 = 48, G2 = 103, G3 = 94, overall failure = 36.73%) were evaluated in 111 subjects. The implant failure was higher in G1 (chi-square = p < 0.001) than in G2 and G3. The chance of implant loss in G1 (OR = 9.8) was higher (p < 0.001) compared to G2 and G3 (no statistical differences). In general, radiolucency, bleeding on probing, probing depth > 5 mm, and the peri-implant annual bone loss demonstrated statistical signifi cance (chi-square, p ≤ 0,001). However, only bleeding on probing (p < 0.001) and bone loss (p = 0.014) were significant on comparison among groups. Conclusion: the failure rate of one-stage morse cone dental implants was higher in the fi rst year of loading.

ABSTRACT

La sustitución de los dientes perdidos en la región estética presenta un complejo desafío debido a la dificultad en la reforma de la apariencia natural y de la anatomía papilar. Se Presenta un caso clínico donde se sustituyó un diente con corona espiga de pronóstico dudoso, por un implante inmediato Avanza. Se trata de una paciente de 24 años de edad atendida en la consulta multidisciplinaria de Implantología de la Clínica Docente de Prótesis de Marianao. Tenía una corona espiga en el incisivo central superior derecho, con cambio de coloración que le afectaba su estética. Además se le caía constantemente y estaba ligeramente inflamada por vestibular, lo cual le producía dolor. Después de una evaluación multidisciplinaria y el consentimiento de la paciente, se procede a la retirada de la corona espiga y exodoncia de la raíz del 11 mediante la técnica de colgajo. Inmediatamente se colocó el implante Avanza y se rehabilitó con una prótesis parcial acrílica removible por razones estéticas. Con este tratamiento, la paciente mantuvo el contorno de los tejidos blandos y la altura ósea de la zona intervenida, necesarios para alcanzar excelentes resultados estéticos(AU)


Replacement of missing teeth from the esthetic region poses a complex challenge to dental specialists due to the difficulties involved in reforming natural appearance and papillary anatomy. A clinical case is presented in which a tooth with a pin crown of doubtful prognosis was replaced with an immediate Avanza implant. A 24-year-old female patient presented at the implantology multidisciplinary service of Marianao Prosthetics University Clinic. The patient had a discoloring pin crown in the upper right central incisor that affected her esthetic appearance. Furthermore, the crown constantly fell out and there was slight vestibular swelling, which caused pain. After multidisciplinary evaluation and having obtained the patients consent, the pin crown was removed and root 11 extracted by flap technique. An Avanza implant was immediately placed and rehabilitated with a removable acrylic partial denture for esthetic reasons. With this treatment, the patient maintained the soft tissue contour and bone(AU)

ABSTRACT

Objetivos: avaliar se a união entre implantes e/ou a presença de gengiva artifi cial infl uencia no sangramento a sondagem dos tecidos peri-implantares. Material e métodos: foram incluídos pacientes tratados com implantes de titânio (Implacil De Bortoli, São Paulo, Brasil), instalados no período de 1998 a 2012, na Universidade de São Paulo (USP). Os implantes foram examinados para avaliação do sangramento a sondagem, sendo divididos de acordo com o tipo de prótese: unitárias (n=167), parciais (n=522) e totais (n=227); e de acordo com a ausência (n=674) ou presença (n=242) de gengiva artifi cial. O teste estatístico com equação de estimativa generalizada foi usado para testar possíveis associações. Resultados: foram examinados 183 pacientes reabilitados com 916 implantes em função, pelo menos por um ano. Ao menos um ponto de sangramento a sondagem foi detectado em 85 (50,9%), 304 (58,2%) e 129 (56,8%) implantes das próteses unitárias, parciais e totais, respectivamente. Em relação à gengiva artificial, 378 (56,1%) dos implantes sem e 140 (57,9%) dos implantes com esta característica apresentaram sangramento a sondagem. Não foram verificadas diferenças significativas entre os grupos. Conclusão: a união dos implantes ou a presença de gengiva artificial não foram associadas com os resultados de sangramento a sondagem nos implantes em função.


Objective: to evaluate whether the prosthesis type (single, partial, complete) and/or the presence of artifi cial gingiva can influence on bleeding on probing of peri-implant tissues. Material and methods: patients treated with titanium dental implants (Implacil De Bortoli, São Paulo, Brazil) between 1998 to 2012 at the University of Sao Paulo (USP) were included in this study. The implants were divided according the following prosthodontic types: single (n=167), partial (n=522), and complete (n=277), and also regarding the presence (n=674) or absence (n=242) or artificial gingiva. The generalized estimating equation test was used to verify possible associations. Results: 183 patients and 916 implants at least 1 year in function were screened. At least one bleeding point was detected in 85 (50.9%), 304 (58.2%), and 129 (56.8%) implants for single, partial, and complete prostheses, respectively. 378 (56.1%) and 140 (57.9%) implant from groups without and with artificial gingiva presented bleeding on probing. No significant differences were identified among groups. Conclusion: the prosthesis design and/or artifi cial gingiva were not associated to bleeding on probing for dental implants in function.

ABSTRACT

Objetivo: avaliar por meio de revisão sistematizada os fatores relacionados à taxa de sobrevivência dos implantes, na técnica de elevação atraumática do seio maxilar (LASM) e a influência das variáveis: técnica, tamanho dos implantes e altura óssea remanescente (AOR). Material e métodos: realizou-se pesquisa de artigos sobre as técnicas de LASM publicados na base de dados PubMed entre junho de 2008 e julho de 2014, com amostra mínima de dez pacientes e follow-up mínimo de seis meses. Estes foram divididos em três grupos: levantamento do seio maxilar com osteótomos sem enxerto ósseo (LSMO), e com enxerto ósseo (LSMOE) e levantamento do seio maxilar com brocas e enxerto (LSMBr). A sobrevivência do implante foi considerada como desfecho primário. Resultados: dos 92 artigos encontrados, apenas 18 foram selecionados, envolvendo 1.228 pacientes e 1.581 implantes. O comprimento dos implantes foi dividido em quatro grupos: 6 mm a 7 mm (8,03%); 8 mm a 10 mm (57,42%); 11 mm a 12 mm (27,21%) e 13 mm a 15 mm (7,34%). A AOR prévia à instalação dos implantes foi dividida em dois grupos (≤ 5 mm, 33,79% e > 5 mm, 66,2%). A taxa de sobrevivência dos implantes nas diferentes técnicas variou entre 93,6% e 100% (LSMO), 90% e 100% (LSMOE), e 92,7% e 96,3% (LSMBr). Quanto ao uso de biomaterial, o Bio-Oss (Geistlich) foi o mais utilizado. Houve maior perda quando da utilização de implantes curtos. Conclusão: o LASM apresenta-se como uma técnica segura com altas taxas sobrevivência dos implantes. Fatores como a técnica de acesso ao seio, AOR e tamanho dos implantes devem ser levados em consideração na execução da técnica.


Objective: to evaluate through a systematic review factors related to implant survival rates regarding the atraumatic sinus lifting technique (AMSLT) and the influence of variables such: technique, implant length, and the remaining bone height (RBH). Material and methods: an electronic search was made at the PubMed from June 2008 to July 2014, with at least 10 patients and six months of follow-up per study. These were divided into three groups: the osteotome maxillary sinus lifting with no bone graft (OMSL-NG), the same but with bone graft (OMSL-G), and maxillary sinus lifting with burs and grafting (MSL-BG). The implant survival was considered as the primary outcome. Results: from the 92 retrieved articles, only 18 were selected, involving 1228 patients and 1581 dental implants. Implant length was divided into four groups: 6-7 mm (8.03%), 8-10 mm (57.42%), 11-12 mm (27.21%), and 13-15 mm (7.34%). The RBH before implant placement was divided into two groups (≤ 5 mm: 33.79% and > 5 mm: 66.2%). The implant survival rates ranged from 93.6%-100% (MSL-BG), 90%-100% (OMSL-G), and 92.7%-96.3% (MSL-BG). The anorganic bovine bone matrix (Bio-Oss, Geistlich) was the most frequent biomaterial. Most losses occurred for short dental implants. Conclusion: The AMSLT is safe with high implant survival rates. Factors such as sinus access, the RBH, and implant lengths must be taken into account during surgical execution.

ABSTRACT

The aim was to present the successful esthetical and functional rehabilitation of partial anodontia in a case of severe ectodermal dysplasia with complete atrophy of the jaws. A 17‑year‑old male with Class III malocclusion with partial anodontia sought dental implant treatment. His expectation was that of Class I occlusion. The challenge in the case was to match the expectation, reality, and the clinical possibilities. Ridge augmentation was performed with a combination of rib graft and recombinant human bone morphogenetic protein‑2. Simultaneously, 6 implants (Nobel Biocare™ ‑ Tapered Groovy) were placed in maxillary arch and 10 in the mandible. Simultaneous placement ensured faster and better osseointegration though a mild compromise of the primary stability was observed initially. After adequate healing, Customized Zirconia Procera™ system was used to build the framework. Zirconia crown was cemented to the framework. Radiological and clinical evidence of osseointegration was observed in all 16 dental implants. Successful conversion of Class III to Class I occlusion was achieved with the combination of preprosthetic alveolar ridge augmentation, Procera™ Implant Bridge system. Abnormal angulations and or placement of dental implants would result in failure of the implant. Hence conversion of Class III to Class I occlusion needs complete and complex treatment planning so that the entire masticatory apparatus is sufficiently remodeled. Planning should consider the resultant vectors that would otherwise result in failure of framework or compromise the secondary stability of the dental implant during function. A successful case of rehabilitation of complex partial anodontia is presented.

ABSTRACT

The purpose of this study was to evaluate patient acceptance and perception of pain with regard to orthodontic mini-implants.The study was conducted on 58 individuals undergoing orthodontic treatment, who had orthodontic mini-implants placed as anchorage devices. Data were collected using a questionnaire containing 6 questions evaluating perception of pain during mini-implant placement and during use, difficulty with cleaning, unaesthetic appearance, difficulty with eating and benefits observed. Data were tabulated and analyzed using Fisher and Spearman’s Correlation Coefficient tests. It was found that 94.8% of the patients reported that they would be willing to undergo treatment with mini-implants again. Of the negative aspects evaluated, the most significant was discomfort during placement, while the least significant was difficulty with eating. Patients’ perception of aspects related to mini-implants was shown to be independent of the quantity ofthese devices placed. Although the patients evaluated some aspects of mini-implants negatively, the mean score for benefits observed was very high, indicating good patient satisfaction with treatment.


O objetivo do presente estudo foi avaliar a aceitabilidade e percepção dolorosa dos pacientes em relação aos mini-implantes ortodônticos. Este estudo foi realizado com 58 indivíduos em tratamento ortodôntico que tiveram a instalação de mini-implantes ortodônticos como recurso de ancoragem. Oinstrumento de coleta de dados foi um questionário contendo 8 perguntas que avaliaram a percepção dolorosa durante a instalação e uso dos mini-implantes, dificuldade de higienização,aspecto anti-estético, dificuldade de alimentação e os benefíciosobservados. Os dados foram tabulados e analisados pelos testes de Fisher e de Coeficiente de Correlação de Spearman. Os resultados demonstraram que 94,8% dos pacientes relataram que se submeteriam novamente ao tratamento com mini-implantes.Dos aspectos negativos avaliados, o mais significante foi o incômodo e dor durante a instalação, enquanto o menos significante foi dificuldade de alimentação. A percepção dos pacientes sobre os aspectos relacionados aos mini-implantesmostrou-se independente da quantidade desses dispositivos instalados. Conclui-se que apesar da avaliação dos mini-implantes pelos pacientes ter apresentado alguns aspectos negativos, o escore médio dos benefícios observados foi bastante alto, indicando boa satisfação dos pacientes com o tratamento.

ABSTRACT

Evaluar los resultados del tratamiento con implantes dentales osteointegrados en la fase quirúrgica. Métodos: se realizó un estudio longitudinal y prospectivo en 802 pacientes en quienes se colocaron 2 165 implantes, en la Clínica Estomatológica Provincial Docente de Santiago de Cuba y la Facultad de Estomatología de La Habana en el decenio 20002009. Se evaluaron las variables: técnica quirúrgica, longitud y diámetro de los implantes, complicaciones intraoperatorias y complicaciones postoperatorias, los resultados del tratamiento se evaluaron en supervivencia y fracaso. Resultados: se logró la supervivencia de los implantes en 705 pacientes para el 87,9 por ciento y se produjo el fracaso en 97 pacientes para el 12,1 por ciento. Se colocaron 2 165 implantes, se logró efectividad de 2 055 para el 94,9 por ciento y fracasaron 110 que representan el 5,08 por ciento. No existen diferencias significativas de los resultados de acuerdo a la técnica quirúrgica empleada. Los implantes que más fracasaron fueron los de 10 mm, para el 34,9 por ciento y 8 mm con el 13,1 por ciento. La efectividad se incrementa a medida que aumenta el diámetro. En las complicaciones intraoperatorias el fracaso fue mayor en relación con la perforación de la tabla ósea con el 92,9 por ciento, inestabilidad con el 86 por ciento y la dehiscencia ósea con el 57,4 por ciento. En el postoperatorio fue notable que en el 100 por ciento de los casos con dolor existió fracaso de los implantes. Conclusiones: en la etapa quirúrgica existe una fuerte asociación de los resultados con la longitud, diámetro de los implantes y la presencia de complicaciones intraoperatorias y postoperatorias(AU)


To evaluate the results of treatment with osseointegrated dental implants in surgery. Methods: A prospective longitudinal study of 802 patients with 2 165 implants, in the provincial teaching dental clinic of Santiago de Cuba and the Dental School of Havana from 2000 to 2009. The surgical techniques evaluated were length and diameter of the implants, surgical and postsurgical complications. The results of treatment were evaluated as survival and failure rates. Results: The dental implants survived in 705 patients for 87.9 percent and failed in 97 for 12.1 percent; 2 165 dental implants were placed, 2 055 were effective for 94.9 percent and 110 failed for 5.08 percent. There are not significant differences among outcomes, depending on the used surgical techniques. Failure was mostly frequent in 10 mm implants, accounting for 34.9 percent and in 8 mm for 13.1 percent. Effectiveness increases as the diameter increases. In intraoperative complications, failure was greater in osseous perforations for 92.6 percent, instability for 86 percent and bone dehiscence for 57.4 percent. In the postsurgical phase, it was noticeable that the implants of 100 percent of patients with pain failed. Conclusions: In the surgical stage, a strong relation between outcomes and length, diameter, and surgical and postsurgical complications was found(AU)

ABSTRACT

The burning problem that all the implantologists are confronted today is the complications and failures occurring with the treatment of osseointegrated implants. To further optimize the treatment outcome, etiologies and factors associated with implant failures should be elucidated. Conceivably such knowledge is needed for developing adequate treatment and prevention strategies. Hence, this paper is intended to provide an insight regarding various aspects of failures that affect dental implants.
