ABSTRACT

ABSTRACT BACKGROUND: Considering the ability of the health and self-management in diabetes questionnaire (HASMID-10) to verify the impact of self-management on diabetes, we highlight its relevance to scientific research and clinical applicability. However, to date, no study has been conducted to scientifically support its use in other languages. OBJECTIVE: To translate, cross-culturally adapt, and validate the HASMID-10 into the Brazilian Portuguese. DESIGN AND SETTING: A translation, cross-cultural adaptation, and validation study conducted at Ceuma University. METHODS: Study was conducted in accordance with the Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measures and Consensus-based Standards for the Selection of Health Measurement Instruments. We included participants of both sexes diagnosed with diabetes, aged between 18 and 64 years, and without cognitive deficits or any other limitations that would prevent them from answering the questionnaire. We assessed participants using the problem areas in diabetes (PAID) scale and HASMID-10. We assessed reliability using a test-retest model with a 7-day interval between assessments. We used intraclass correlation coefficient (ICC), 95% confidence interval (CI), standard error of measurement (SEM), minimum detectable difference (MDD), Spearman correlation coefficient, and floor and ceiling effects. RESULTS: Sample comprised 116 participants, most of whom were women, overweight, non-practitioners of physical activity, and nonsmokers. We observed significant correlations (P = 0.006; rho = −0.256) between the HASMID-10 and PAID, adequate reliability (ICC = 0.780) and internal consistency (Cronbach's alpha = 0.796). No ceiling or floor effects were observed. CONCLUSION: HASMID-10 has adequate measurement properties and may be used for Brazilians.

ABSTRACT

Objective: to present the radiographic clinical follow-up of the prosthetic rehabilitation of a patient with an atrophic mandible, with the installation of short implants associated with an implant of regular length. Method: case report of a completely edentulous patient with an atrophic mandible and a 6-year radiographic clinical follow-up conducted at the dental clinic of the Federal University of Piauí, Teresina, from February 2011 to January 2020. After collecting sociodemographic data, health records, clinical radiographic examinations, and prosthetic surgical planning, four dental implants were installed between the mental foramina. After three months, mini-conical abutments and a fixed prosthesis screwed onto the implants were installed and monitored every six months for a period of six years. Results: the clinical evaluation revealed tissue stability without significant peri-implant changes after the follow-up period. Radiographically, bone resorption was not observed around the implant. Stability of the prosthesis and absence of prosthetic complications were observed during the follow-up period. Conclusion: short implants associated with regular-length implants can be placed in the anterior region of an atrophic mandible for rehabilitation with fixed complete dentures.

ABSTRACT

Abstract Background Self-care in the management of systemic arterial hypertension (SAH) is crucial, and validated instruments can help researchers and health professionals to plan strategies to improve self-care in people with SAH. Objective The main objective of this study was to translate, cross-culturally adapt, and validated the Hypertension Self-Care Profile (HBP-SCP) for Brazilian Portuguese. Methods The translation and cross-cultural adaptation was performed in five phases, and the pre-final version was tested in 30 individuals, native speakers of Portuguese with a diagnosis of hypertension. The final version was administered in 100 individuals. The inclusion criteria were: diagnosis of SAH, characterized by systolic arterial blood pressure ≥ 140 mmHg and/or diastolic arterial blood pressure ≥ 90mmHg, regular use of antihypertensive medications and over 18 years of age. The present study also used two other questionnaires, previously validated for the Brazilian population, to verify the validity of the construct, the Healthy Habits Perception Questionnaire (HHPQ) and the Quality of Life in Hypertension Mini-Questionnaire (MINICHAL-BRASIL). Results During the translation and cross-cultural adaptation phase, there were no disagreements. Adequate reliability — intraclass correlation coefficient (ICC) ≥ 0.89, standard error of measurement (SEM) % ≤ 4.34, minimum detectable change (MDC) % ≤ 12.04 — and internal consistency (Cronbach's alpha ≥ 0.75) were observed. The behavior domain of HBP-SCP obtained significant correlations (p < 0.05) with the self-efficacy domain and HHPQ; the motivation domain with the self-efficacy domain; and the self-efficacy domain with the somatic manifestation domain of MINICHAL-BRASIL. No ceiling and floor effects were observed. Conclusions The Brazilian Portuguese version of the HBP-SCP has adequate psychometric properties, according to the best scientific recommendations.

ABSTRACT

SUMMARY OBJECTIVE: The aim of this study was to assess the inter-reliability of the Braden scale and its subscales for different patients assisted in the intensive care unit. We hypothesized that the Braden scale has low reliability in different populations. METHODS: This reliability study involved the Braden scale in intensive care unit of a hospital. A total of 200 patients were admitted to the intensive care unit in four different groups: neurological patients, sepsis, elderly, and adults affected by trauma. The Braden scale is a tool composed of six subscales for patient assessment: sensory perception, humidity, activity, mobility, nutrition, and friction. The total score was also calculated. The Braden scale was applied by two different nurses with an interval of 20-30 min between applications. RESULTS: For all populations, kappa values considered unsuitable were observed for most categories of the Braden scale, ranging from 0.06-0.25. Only for the total Braden scale score was moderate reliability identified in all groups evaluated, with intraclass correlation coefficient values ranging from 0.48-0.75. CONCLUSIONS: Braden scale is not a reliable tool to be used in the intensive care unit, and we do not recommend the use of this scale to assess the risk of developing pressure injury.

ABSTRACT

SUMMARY OBJECTIVE: This study aimed to validate the internal structure of the Brazilian version of the Baecke Habitual Physical Activity Questionnaire. METHODS: A cross-sectional study was conducted with individuals over 18 years old of both sexes, with Brazilian Portuguese as their native language. The structure of the Baecke Habitual Physical Activity Questionnaire was tested by confirmatory factor analysis. The model fit was evaluated by the following indices: root mean square error of approximation, comparative fit index, Tucker-Lewis index, standardized root mean square residual, and χ²/degrees of freedom. We used the Akaike information criterion and Bayesian information criterion to compare different structures of the Baecke Habitual Physical Activity Questionnaire. RESULTS: A total of 241 individuals participated in this study. The original structure of the Baecke Habitual Physical Activity Questionnaire with 16 items and 3 domains was compared to a structure with 14 items and 3 domains. The internal structure of the Baecke Habitual Physical Activity Questionnaire with 14 items showed better fit indices and lower Akaike information criterion and Bayesian information criterion values. CONCLUSION: The best internal structure of the Brazilian version of the Baecke Habitual Physical Activity Questionnaire in adults presents 3 domains and 14 items.

ABSTRACT

ABSTRACT Objective: The aim of this study was to evaluate the effectiveness of XP-endo Finisher (XP) on removal of the smear layer in root canals by comparing different irrigation protocols. Methods: Seventy-two human single-rooted teeth were similarly instrumented using R25 Reciproc files (VDW, Munich, Germany) applied in reciprocating mode with a VDW GOLD endo motor (VDW, Munich, Germany). The working length was determined at 1 mm short of the apical foramen. The canals were irrigated with 5 mL of 2.5% sodium hypochlorite during instrumentation. The teeth were divided at random into six groups (n=12). A control group, which was not submitted to the final irrigation protocol, and five experimental groups with different irrigants and agitation techniques: EDTA/File, EDTA/XP, EDTA/Passive Ultrasonic Irrigation (PUI), Distilled Water (DW)/XP, and DW/PUI). Smear layer removal quality scores were assessed in the apical, middle, and cervical thirds of the root canal based on images obtained by scanning electron microscopy. Data were analyzed using the Kruskal-Wallis test, followed by two-by-two comparisons with the Dunn test (α=5%). Results: EDTA/File, EDTA/PUI, and EDTA/XP groups demonstrated significantly lower scores than the other groups (P<0.05) in all thirds evaluated. No significant difference was observed between the groups in which distilled water was used and the control group in all thirds evaluated (P> 0.05). Conclusion: The XP-endo Finisher file did not increase the efficiency of EDTA in removal of the smear layer in root canals.


RESUMO Objective: Avaliar a eficácia do XP-endo Finisher (XP) na remoção da smear layer em canais radiculares, comparando diferentes protocolos de irrigação. Métodos: Setenta e dois dentes humanos unirradiculares foram similarmente instrumentados usando limas R25 (VDW, Munich, Germany) aplicadas no modo reciprocrantes em um motor endodôntico VDW GOLD (VDW, Munich, Germany). O comprimento de trabalho foi determinado a 1 mm aquém do forame apical. Os canais foram irrigados com 5 mL de hipoclorito de sódio 2,5% durante a instrumentação. Os dentes foram divididos aleatoriamente em seis grupos (n=12). Um grupo controle, que não foi submetido ao protocolo final de irrigação, e cinco grupos experimentais com diferentes irrigantes e técnicas de agitação: EDTA/Lima, EDTA/XP, EDTA/Irrigação Ultrassônica Passiva (IUP), Água destilada (AD)/XP, e AD/IUP). Os escores de qualidade de remoção da camada de smear layer foram avaliados nos terços apical, médio e cervical do canal radicular com base em imagens obtidas por microscopia eletrônica de varredura. Os dados foram analisados pelo teste de Kruskal-Wallis, seguido de comparações dois a dois pelo teste de Dunn (α = 5%). Resultados: Os grupos EDTA/lima, EDTA/PUI e EDTA/XP demonstraram escores significativamente menores que os outros grupos (P <0,05). Não foi observada diferença entre os grupos que utilizaram água destilada e o grupo controle em todos os terços avaliados (P> 0.05). Conclusão: A lima XP-endo Finisher não aumentou a eficiência do EDTA na remoção da smear layer em canais radiculares.

ABSTRACT

Avaliou-se in vitro o módulo de elasticidade e resistência flexural de três resinas compostas utilizadas para fixação de bráquetes ortodônticos, quando submetidas aos ciclos de des-remineralização. Foi empregada uma matriz metálica bipartida para confecção de 90 amostras. Três grupos experimentais utilizando diferentes resinas compostas foram formados (n=30 cada): G1-Filtek Z250 (3M), G2-Transbond XT (3M) e G3- Filtek P90 (3M). Metade das amostras de cada grupo (n=15) foram submetidas aos ciclos de des-remineralização, simulando condições de alto desafio cariogênico; as demais foram armazenadas em saliva artificial servindo como controle. Decorrido 10 dias, foi realizado o ensaio mecânico de resistência à flexão de 3 pontos na máquina de ensaio universal (EMIC DL 2000), utilizando célula de carga de 50 KgF e velocidade de 0,5 mm/min até a fratura das amostras. Os resultados foram submetidos à análise estatística Análise de Variância (ANOVA) e comparação múltipla de Tukey (5%). Verificou-se que os valores médios de resistência flexural para as resinas de G1, G2 e G3 apresentaram diferenças estatisticamente significantes, porém a alteração nos ciclos de des-remineralização não promoveu diferenças estatisticamente significante entre os grupos (p=0.562). Já para o módulo de elasticidade, tanto o efeito interação, bem como os tipos de resinas para fixação dos bráquetes e os ciclos des-remineralizantes (p=0,00) apresentaram diferenças estatísticas significantes. As resinas compostas apresentam diferentes valores de resistência flexural e módulo de elasticidade, sendo que as condições de alto desafio cariogênico podem alterar significativamente o módulo de elasticidade desses materiais.


This study has evaluated in vitro the modulus of elasticity and flexural strength of three composites, used for bonding of orthodontic brackets when subjected to pH cycles. A split metallic matrix was used for the confection of 90 samples. Three experimental groups were formed using different composite resins (n= 30): G1- Filtek Z250 (3M), G2-Transbond XT (3M), and G3- Filtek P90 (3M). Half of the samples from each group (n=15) were submitted to de-remineralization cycles, conditions simulating high cariogenic challenge, the others were stored in artificial saliva, as control. After 10 days, the three points flexural strenght test was conducted using an universal testing machine (EMIC DL 2000) with load cell of 50 kgf and speed of 0.5 mm / min until sample fracture. Statistical analysis was done by analysis of variance test (ANOVA) and Tukey multiple comparison (5%), it was found that the mean values of flexural strength for G1, G2, and G3 showed statistically significant differences, but the change in pH cycles did not promote significant statistical difference (p =0.562). For the modulus of elasticity, it was observed that both the interaction effect and the types of resins for bonding the brackets and the pH cycles (p=0,00) presented significant statistical differences. The composites exhibit different flexural strength and modulus of elasticity values, and the high cariogenic challenge conditions can significantly alter the elastic modulus of these materials

ABSTRACT

AIM: To evaluate the influence of varying the water/powder ratio on the compressive strength of type IV mineral and synthetic casts. METHODS: Four commercial brands of type IV mineral and synthetic casts were evaluated: Durone, Herostone, Fuji Rock, and Elite Rock. Ninety-six test samples were prepared from a silicone matrix, according to ADA's standard no. 25. The samples were prepared according to the manufacturer's recommendations with a normal water/powder ratio (n = 12) and with 20% extra water (n = 12), forming the control (A) and experimental (B) subgroups, respectively. Compressive strength tests were performed using a universal testing machine EMIC (DL 2000) with a load cell of 2,000 kgf/cm2. The obtained data were analyzed statistically using two-way ANOVA and Tukey's test (α=5%). RESULTS: The synthetic Elite Rock cast was statistically different from the one obtained when the portion of water indicated by the manufacturer was used; no significant differences were found in the remaining casts when the proportion of water was increased by 20%. CONCLUSIONS: the groups of synthetic and mineral casts differed and the water increase (20%) did not cause significant difference on the compressive strength of the materials...

ABSTRACT

A documentação ortodôntica clássica consiste emtelerradiografia, radiografia panorâmica, fotografias e modelos degessos, sendo este último item peça fundamental para diagnosticar asmás-oclusões e formular planos de tratamento. Propôs-se, com estarevisão de literatura, discorrer sobre a utilização dos modelos digitais naOrtodontia, sua precisão e eficácia em relação aos modelos de gessoconvencionais. Melhorar a comunicação entre profissionais, laboratóriose reduzir espaço físico são algumas das vantagens dos modelosdigitais. Os sistemas digitais de escaneamento em Odontologia estãoem evolução desde a sua introdução, na década 1980. Atualmente, osmodelos digitalizados podem ser obtidos através de escaneamento damoldagem, do modelo de estudo em gesso ou escaneamento diretona cavidade bucal. Ainda, podem estar associados a outras imagens,como a tomografia computadorizada cone-beam (TCCB). Buscando avalidação de uma técnica que substitua o modelo de estudo convencional,diversos estudos vêm testando os métodos de obtenção domodelo digital, assim como os softwares responsáveis pelo manejodesses modelos. A partir desta revisão, pôde-se concluir que os modelosdigitais são confiáveis clinicamente, tanto quanto os modelos degesso convencionais. O método indireto (escaneamento do modelo degesso) é o mais utilizado, e dentre os softwares existentes, o OrthoCADé o mais testado. A TCCB associada aos modelos digitais apresenta-secomo um forte recurso para o diagnóstico e o planejamento de casosinterdisciplinares (Ortododontia e Cirurgia Ortognática).


The documentation consists of classic orthodonticradiography, panoramic radiography, photographs and plasters models,the latter being a key to diagnosing malocclusion and formulatetreatment plans. It is proposed to discuss this review of the literatureon the use of digital models in orthodontics, accuracy and efficiencycompared to conventional plaster models. Improving communicationbetween professionals, laboratories and reduce physical space aresome of the advantages of digital models. Digital systems scanning indentistry are evolving since its introduction in the mid 80s. Currentlythese can be obtained by scanning of the molding, of the plaster modelstudy ar scanning directly into the buccal cavity ar cone beam computedtomography (CBCT). Seeking validation of a technique that replacethe conventional model study, several studies testing the methods ofobtaining the digital model as well as softwares responsible for themanagement of these models are reported in the literature. From thisreview we conclude that the digital models are clinically reliable and areas accurate and efficient as conventional plaster models. The indirectmethod Iscanning the plaster model) is the most used, and amongexisting software, OrthoCAD is the most tested and employee. The CBCTassociated with digital models presents itself as a strong resource forthe diagnosis and planning of interdisciplinary cases (orthodontic andorthognathic surgery).

ABSTRACT

BACKGROUND AND OBJECTIVES: University professors are part of a category of professionals constantly submitted to stress, which may trigger a temporomandibular disorder (TMD). By recognizing this relationship, this study aimed at evaluating the prevalence and severity of TMD in university professors. METHODS: A sample of 200 individuals of both genders, above 25 years of age, who were still not diagnosed with TMD, was divided in two groups: Group I, made up of university professors, and Group II made up of individuals of any other professional activity, different from teaching. Volunteers were asked to fill a historical questionnaire which allowed a classification of the presence and severity of TMD. RESULTS: Participated in this study 95 males and 105 females. With regard to TMD severity in Group I, it was observed that 62.7% of evaluated individuals were classified as having mild TMD; 25.3% as having moderate TMD; and 12% as having severe TMD. In Group II, 73.9% had mild TMD; 24.6% had moderate TMD; and 1.4% had severe TMD. CONCLUSION: The prevalence of TMD among professors was not different from the group of non professors. When professors had TMD, the level severity was higher as compared to non professors.


JUSTIFICATIVA E OBJETIVOS: O professor de ensino superior faz parte de uma categoria de profissionais que é submetida constantemente a estresse, podendo desencadear uma disfunção temporomandibular (DTM). Ao reconhecer essa relação, este trabalho teve como objetivo avaliar a prevalência e grau de gravidade de DTM em professores de ensino superior. MÉTODOS: Uma amostra de 200 indivíduos, de ambos os gêneros, maiores de 25 anos, que ainda não tinham diagnóstico de DTM, foi dividida em dois grupos: o Grupo I, formado por indivíduos que exerciam a profissão de professor de ensino superior e o Grupo II, formado por indivíduos que exerciam qualquer outra atividade profissional desvinculada da docência. Aos voluntários, foi solicitado o preenchimento de um questionário anamnésico que permitiu estabelecer uma classificação em relação à presença e ao grau de gravidade da DTM. RESULTADOS: Foram avaliados 95 homens e 105 mulheres. Em relação ao grau de gravidade de DTM no Grupo I, detectou-se que 62,7% dos avaliados foram classificados como portadores de DTM leve; 25,3% como portadores de DTM moderada; e 12% como portadores de DTM grave. No Grupo II, constatou-se que 73,9% como portadores de DTM leve; 24,6% DTM como portadores de DTM moderada; e 1,4% como portadores de DTM grave. CONCLUSÃO: A prevalência de DTM em professores não foi diferente da encontrada no grupo de não professores; quando professores foram acometidos por DTM, o grau de gravidade foi maior quando comparado com o grupo de não professores.

ABSTRACT

O objetivo deste trabalho foi avaliar, através de uma revisãode literatura, os avanços em sistemas adesivos utilizados para colagemde braquetes, analisando a adesão e a prevenção da desmineralizaçãodurante o tratamento ortodôntico. Um dos principais marcos na Odontologiarestauradora foi o surgimento dos sistemas adesivos. Estes,por sua vez, foram aplicados nas diversas especialidades, entre elasa Ortodontia. Os sistemas adesivos convencionais, que empregam atécnica do condicionamento ácido total da estrutura dental, foram eainda são amplamente utilizados. Porém, adesivos autocondicionantesque apresentam monômeros acídicos em sua composição vêm sendodesenvolvidos na tentativa de simplificar etapas na técnica adesivae uma adequada capacidade de união ao esmalte. Por meio desseestudo, foi possível concluir que os sistemas adesivos convencionaissão os mais utilizados e representam o padrão ouro para a colagem debraquetes. Entretanto, os sistemas autocondicionantes são uma opçãopromissora, por apresentar técnica simplificada e adequada capacidadede união do braquete ao esmalte. A introdução de agentes antimicrobianospoderia reduzir ou minimizar o aparecimento de áreas dedescalcificação, porém, sua eficácia clínica ainda não foi comprovada.


The objective of this study was to evaluate, throughliterature review, the evolution of adhesive systems used for bondingbrackets. The main topics discussed were adhesion and preventionof demineralization during orthodontic treatment. The conventionaladhesive systems, which employ the technique of total etching, wereand still are widely used. However, the self-etching adhesives have acidicmonomers in their composition and were developed in an attempt tosimplify steps in adhesive technique and adequate capacity enamelbond. This study concluded that the conventional adhesive systemsare the most widely used and represent the gold standard for bondingbrackets. However, the self-etching systems are a promising option forpresenting a simplified technique and adequate bonding capacity thebracket to the enamel. The introduction of antimicrobial agents couldreduce or minimize the presence of decalcification areas, but they stilldo not have a clinical efticacy.

ABSTRACT

Este estudo teve por objetivo avaliar in vitro a quantidade de torque manual gerada por profissionais de diferentes gêneros em parafusos utilizados em próteses implantossuportadas. Um manequim odontológico foi usado para simular uma condição clínica. Quatro implantes osseointegrados foram instalados na área de primeiro e segundo molar inferior direito e esquerdo. Dez profissionais participaram do estudo sendo que aos mesmos foi solicitado aplicar o torque máximo a quatro tipos de parafusos diferentes (Parafusos UCLA de titânio, UCLA de ouro, de retenção de ouro e esteticone). Após o torque aplicado, foi medido o destorque que foi considerado como o torque gerado. Cada participante realizou este procedimento três vezes em cada parafuso, com intervalo de tempo de 1 minuto. Os resultados encontrados mostraram diferenças significativas entre os profissionais, mas não entre o gênero masculino e feminino. Concluiu-se que quando o torque é aplicado de forma manual espera-se uma variabilidade na quantidade de torque gerada, mas não existindo diferenças estatisticamente significantes entre profissionais de diferentes gêneros


This study aimed to evaluate in vitro the amount of torque generated manually by professionals from different genres in different types of screws used in implant prosthesis. A dental mannequin was used to simulate a clinical condition. Four dental implants were attached in the area of the first and second molar right and left. Ten professionals have participated, and were asked to apply the maximum torque to four different types of screw (titanium and gold screws UCLA, gold retention screw and esteticone). After applying the torque, detorque was measured and considered as generated torque. Each professional has performed this procedure three times with each screw with one minute interval. Results have shown significant differences among professionals, but not between males and females. Therefore it was concluded that when torque is applied manually a variability in the quantity of generated torque is expected, but with no significant differences between professionals from different genres

ABSTRACT

As técnicas existentes para posicionamento do implante zigomático geram variações no contato final osso/implante. Entretanto, clinicamente, não se sabe como isto afeta os valores de sobrevivência. O objetivo deste estudo foi verificar se diferentes modelos biomecânicos afetam os valores de dobramento em implantes zigomáticos não osseointegrados. Assim, duas investigações independentes foram realizadas; 60 implantes zigomáticos de 55 mm de comprimento foram utilizados. Na primeira etapa (M; n = 30), os implantes foram fixados em uma interface metálica. Na segunda etapa (B; n = 30), os implantes foram fixados em osso bovino congelado em temperatura controlada e retirados pouco antes do ensaio. Em cada etapa, as porções apicais dos implantes foram inseridas 8 mm, 10 mm e 12 mm nos blocos de fixação. Os implantes foram montados em 45 graus e submetidos à carga axial até deformação. Os valores máximos de dobramento foram registrados em quilogramas-força e o deslocamento em milímetros. Dentro de cada fase, os dados foram comparados pela análise de variância. O teste t Student foi usado para comparações entre as fases (nas respectivas profundidades de inserção). O nível de significância foi 5%. Na primeira etapa, as diferenças foram significativas apenas entre os grupos M8 e M12 (Anova um critério; p = 0,013). Entretanto, na segunda etapa, a comparação da força máxima entre os grupos não resultou em diferenças estatisticamente significantes. Os valores médios de dobramento nos grupos M foram estatisticamente maiores do que nos grupos B (p < 0,05). Pôde-se concluir que: a) nos modelos M, a resposta mecânica é melhor para implantes com 10 mm de inserção ou mais; b) o modelo biomecânico escolhido altera os valores de resistência ao dobramento.


Current techniques for zygoma dental implant placement can generate different bone-to-implant contact configurations. However, their influence on clinical survival rates is unknown. The aim of this study was to verify the influence of different biomechanical models on bending values for non-osseointegrated zygomatic fixtures. For this, two independent investigations were performed. Sixty 55 mm implants were used. In the first phase (M) (n=30), all implants were secured with a metallic interface. In the second phase (B) (n=30), implants were installed into fresh-frozen bone under controlled temperature conditions just before final test. Three insertion implant depths (8 mm, 10 mm, and 12 mm) were chosen. After, the implants were mounted in a 45-degree inclination and submitted to axial loading at the coronal portion until deformation. Maximum bending strength values were registered in kilograms-force and displacement in millimeters. The analysis of variance test was used to compare data among groups (within each phase). Also, a Student´s t test was performed to compare data between M and B depths. The level of significance was 5%. Significant differences were observed between M8 and M12 (one-way Anova; p = 0,013). However, no significant differences were among B groups. Bending values found in M were statistically higher than in B (p < 0,05). It can be concluded that: 1) In the M phase, the mechanical response is better for 10mm insertion depths or higher, and 2) the biomechanical model influences on the final strength values

ABSTRACT

A harmonia dento gengival é fundamental na estética do sorriso. Reabilitações protéticas dos dentes anteriores precisam de uma avaliação cuidadosa do arco côncavo gengival, presença de papilas interdentárias, espessura das áreas de pônticos, assim como do zênite gengival. Este trabalho apresenta a descrição de um caso clínico com abordagem estética multidisciplinar onde foi recuperada a espessura da área de pôntico a partir de cirurgia de enxerto gengival livre. Posteriormente realizado condicionamento dessa área, usou-se como guia as restaurações provisórias para obtenção do arco côncavo gengival em harmonia com os dentes. Associado a isto, foram confeccionadas restaurações cerâmicas com infraestruturas em zircônia, tendo como guia as restaurações provisórias e aplicação dos princípios estéticos


The harmony is fundamental in dento gingival smile esthetics. Prosthetic rehabilitation of anterior teeth requires careful evaluation of gingival concave arc, the presence of interdental papillae, thick areas of pontics and the gingival zenith. This paper presents the description of a clinical case with aesthetic multidisciplinary approach where the thickness was recovered from the area of the pontic from free gingival graft surgery. Later gingival conditional, used as a guide the provisional restorations for obtaining gingival concave arc in harmony with his teeth. Additionally, were fabricated ceramic restorations with zirconia infrastructures, guided the temporary restorations and application of aesthetic principles

ABSTRACT

OBJECTIVE: The purpose of this study was to evaluate the reliability and accuracy of a radiographic analysis method for the location of mini-implants inserted in the posterior region of the maxilla. MATERIAL AND METHODS: Two self-drilling mini-implants were installed between the second premolar and the first molar on the right side and left side in three dry skulls. Three operators performed three occlusal radiographs, using an occlusal x-ray film holder, at three different times in each of the three skulls. RESULTS: The interclass correlation coefficient showed a significantly high, positive correlation (p<0.05), indicating an excellent reliability between operators. The analysis of variance showed no significant differences in time and among the operators. CONCLUSION: Based of these findings, it may be concluded that this methodology can be used by several operators in longitudinal clinical studies on orthodontic mini-implants at the anterior-posterior and lateral-medial locations or longitudinal displacement.

ABSTRACT

Atualmente as próteses implantossuportadas são a primeira alternativa de tratamento na reabilitação de arcos desdentados parciais ou totais, porém muitas vezes, existem limitações de ordem anatômica, sistêmica ou econômica que impossibilitam esse tipo de tratamento. Um recurso que pode ser considerado, quando não é possível este tipo de tratamento é o uso de próteses fixas conjugadas a PPR com encaixes (attachments). Esses são componentes alternativos aos grampos convencionais e sua indicação é baseada nas particularidades de cada caso e na disponibilidade, normalmente os encaixes rígidos são indicados para casos próteses conjugadas dentossuportadas enquanto que os semirígidos ou resilientes para os casos de extremidades livres. Com base nessas considerações o presente trabalho tem como objetivo apresentar dois casos clínicos de reabilitação com PPR retida por encaixes resilientes de semiprecisão associados à prótese fixa. Obteve-se resultados satisfatórios, quanto a estética e funcionalidade, destacando-se a importância de um bom planejamento para o sucesso do tratamento


Currently implant supported prostheses are the first choice of treatment in rehabilitation of partially or totally edentulous arches, but there are often limitations in anatomic, systemic or economic precluding this type of treatment. One feature that may be considered when this kind of treatment is not possible the use of bridges combined with the RPD attachments. These components are alternatives to conventional clips and its indication is based on the particularities of each case and the availability, attachments normally rigid prostheses are indicated for cases combined dental-supported while the semi rigid or resilient to the cases of free ends. Based on these considerations this paper aims to present a case of rehabilitation with RPDs retained by resilient attachments for semi precision associated with the fixed prosthesis. We obtained satisfactory results, as the aesthetics and functionality, highlighting the importance of good planningfor successful treatment

ABSTRACT

OBJECTIVES: The purpose of this in vitro study was to evaluate misfit alterations at the implant/abutment interface of external and internal connection implant systems when subjected to cyclic loading. MATERIAL AND METHODS: Standard metal crowns were fabricated for 5 groups (n=10) of implant/abutment assemblies: Group 1, external hexagon implant and UCLA cast-on premachined abutment; Group 2, internal hexagon implant and premachined abutment; Group 3, internal octagon implant and prefabricated abutment; Group 4, external hexagon implant and UCLA cast-on premachined abutment; and Group 5, external hexagon implant and Ceraone abutment. For groups 1, 2, 3 and 5, the crowns were cemented on the abutments and in group 4 crowns were screwed directly on the implant. The specimens were subjected to 500,000 cycles at 19.1 Hz of frequency and non-axial load of 133 N in a MTS 810 machine. The vertical misfit (μm) at the implant/abutment interface was evaluated before (B) and after (A) application of the cyclic loading. Data were analyzed statistically by using two-away ANOVA and Tukey's post-hoc test (p<0.05). RESULTS: Before loading values showed no difference among groups 2 (4.33±3.13), 3 (4.79±3.43) and 5 (3.86±4.60); between groups 1 (12.88±6.43) and 4 (9.67±3.08), and among groups 2, 3 and 4. However, groups 1 and 4 were significantly different from groups 2, 3 and 5. After loading values of groups 1 (17.28±8.77) and 4 (17.78±10.99) were significantly different from those of groups 2 (4.83±4.50), 3 (8.07±4.31) and 5 (3.81±4.84). There was a significant increase in misfit values of groups 1, 3 and 4 after cyclic loading, but not for groups 2 and 5. CONCLUSIONS: The cyclic loading and type of implant/abutment connection may develop a role on the vertical misfit at the implant/abutment interface.
