ABSTRACT

As recessões gengivais podem causar hipersensibilidade dentinária, desconforto estético e aumentar a prevalência de cáries ou lesões cervicais não-cariosas. Cirurgias para recobrimento radicular associadas a enxertos têm sido consideradas padrão ouro no tratamento das recessões gengivais. OBJETIVO: Comparar o enxerto de tecido conjuntivo e uma matriz de colágeno xenógena no recobrimento radicular de recessões gengivais unitárias em fenótipo gengival fino, em 6 meses de acompanhamento. METODOLOGIA: Este ensaio clínico, controlado, randomizado, duplo cego, de boca dividida, avaliou 28 pacientes com recessões gengivais bilaterais submetidos à cirurgia para recobrimento radicular, através do retalho estendido associado ao enxerto de tecido conjuntivo subepitelial (grupo controle) e matriz de colágeno (grupo teste). Os parâmetros avaliados foram profundidade de sondagem, recessão gengival, nível clínico de inserção, mucosa ceratinizada e sangramento à sondagem tanto dos dentes que receberam os enxertos, como dos dentes distais e mesiais a esse. Além de espessura gengival e alteração do fenótipo gengival dos dentes que receberam os enxertos, dor pós-operatória e qualidade de vida, através do Oral Health-Related Quality of Life, no baseline, três e seis meses após a cirurgia. Os dados foram analisados estatisticamente através dos testes de Friedman, Wilcoxon, Mann-Whitney, Qui-quadrado, McNemar, ANOVA e teste t, sendo pré-estabelecido um nível de significância de 5%. RESULTADOS: 14 homens e 14 mulheres foram incluídos, com uma média de idade de 30,3 (± 6,2) anos. Foram observadas reduções estatisticamente significativas para a recessão gengival e ganho significativo do nível clínico de inserção tanto dos dentes que receberam os enxertos (p<0,001), como dos dentes distais (p=0,001) e mesiais (p<0,001), na análise intragrupo, em ambos os grupos de tratamento, nos períodos avaliados. Além disso, houve aumento significativo da mucosa ceratinizada (p<0,001) e espessura gengival (p<0,001) para os grupos teste e controle, respectivamente, com diferença significativa entre os grupos de tratamento. O protocolo de tratamento proposto também foi capaz melhorar a qualidade de vida (p<0,001). CONCLUSÃO: Ambos os tratamentos resultaram em melhoria dos parâmetros clínicos avaliados em seis meses de acompanhamento. A matriz de colágeno representa uma excelente alternativa ao enxerto de tecido conjuntivo subepitelial no tratamento de recessões gengivais unitárias em fenótipo gengival fino (AU).


Gingival recession may cause dental hypersensitivity, esthetical discomfort and increase the prevalence of carious or non-carious cervical lesion. Root coverage procedures using grafts placement has been the gold standard on this treatment. AIM: To compare the root coverage performed connective tissue graft and collagen matrix using the extended flap technique in single gingival recessions in thin gingival phenotype, at 6 months of follow- up. METHOD: This controlled, randomized, double-blind, split-mouth, clinical trial evaluated 28 patients with bilateral gingival recession subjected to root coverage procedure through extended flap technique with subepithelial connective tissue graft (control) and xenogenic collagen matrix (test). The parameters evaluated were deep on probing, gingival recession, clinical attachment level, keratinized mucosa and bleeding on probing for teeth that received the graft and the distal and mesial teeth. In addition, gingival thickness and gingival phenotype change of the teeth that received the grafts, postoperative pain and quality of life through Oral Health-Related Quality of Life, at baseline, three and six months after surgery. The data were statistically analyzed through the tests of Friedman, Wilcoxon, Mann-Whitney, Qui-quadrado, McNemar, ANOVA and t Test. The significance level of 5% was pre-estlablished. RESULTS: 14 men and 14 women were included, with an average of 30.3 years (± 6.2). Statistically significant reductions were observed for gingival recession and clinical attachment level significant increase of both teeth of the grafts (p <0.001), distal (p=0.001) and mesial (p<0.001) teeth, within each group and in both treatment groups, during the follow-up. In addition, there was keratinized mucosa significant increase (p <0.001) and gingival thickness (p<0.001) for test and control group, respectively, with statistical difference between groups. The treatment protocol was able to improve the quality of lite (p<0.001). CONCLUSION: Both treatments resulted in improved clinical parameters at six months of follow-up. The collagen matrix represents an excellent alternative to the subepithelial connective tissue graft in the treatment of single gingival recessions in thin gingival phenotype (AU)

ABSTRACT

O objetivo deste trabalho foi apresentar o relato de um caso clínico no qual uma paciente de 52 anos, com ausência de tecido queratinizado na região de rebordo do elemento 46, previamente extraído, foi submetida à cirurgia de enxerto gengival livre para criar uma faixa de tecido queratinizado, antes da instalação do implante osseointegrado. Após três meses de cicatrização, foi constatado signifi cativo ganho de tecido queratinizado na região, tornando o sítio mais favorável à reabilitação com implante dentário. Dessa forma, foi seguido o planejamento inicial e instalado um implante na região, que foi reabilitado posteriormente. Diversos trabalhos têm mostrado que o selamento biológico proporcionado por uma adequada faixa de tecido queratinizado ao redor de implantes seria um pré-requisito para a saúde e o sucesso desses implantes no longo prazo. A revisão clínica e radiográfi ca com três anos de acompanhamento mostrou estabilidade do tecido peri-implantar e, consequentemente, o sucesso do tratamento proposto.


The aim of this study was to present a clinical case report where a 52-year-old patient, with absence of keratinized tissue in the ridge region of the previously extracted element 46, received a free gingival graft surgery to create a tissue band before the osseointegrated implant installation. After 3 months of healing, a signifi cant gain of keratinized tissue was observed in the region, making the site more amenable to rehabilitation with a dental implant. In this way, the initial planning was followed and an implant was installed in the region and the restoration delivered afterwards. Several studies have shown that biological sealing provided by a suitable range of keratinized tissue around implants would be a prerequisite for the health and success of these implants in the long run. The clinical and radiographic review with 3 years of follow-up showed stability of the peri-implant tissue and, consequently, the success of the proposed treatment.

ABSTRACT

A recessão gengival é uma queixa relativamente comum entre os pacientes quando procuram o cirurgião-dentista, e os motivos desse incômodo são sensibilidade e estética. Os autores relatam que o tratamento de recessões gengivais posteriores bilaterais são realizados a partir do transplante do tecido conjuntivo subepitelial. Já a técnica operatória utilizada nesse caso, para o posicionamento do tecido conjuntivo, foi a de Langer, com reposicionamento coronário do retalho. Houve um aumento considerável com relação ao recobrimento radicular, sugerindo um processo de reparação da recessão gengival bilateral, com a interposição do tecido conjuntivo na área receptora. Em relação à praticidade, a técnica de Langer mostra-se mais fácil de ser realizada com relação ao aspecto estético, recobrimento, ganho em altura e espessura. O objetivo desse trabalho é relatar um caso clínico de resolução estética para recessão gengival. A terapia inicial do presente caso consistiu em instruções de higiene oral acompanhado de raspagem dos dentes nos 30 dias anteriores à cirurgia. Os procedimentos cirúrgicos foram feitos seguindo técnica consagrada pela ciência. O enxerto de tecido do palato foi transplantado para a região de recessão, a fim de recobrir as áreas de exposição radicular. O paciente recebeu instruções de cuidados de higiene. Após 14 dias do pós-cirúrgico, realizou-se a remoção dos pontos e uma instrução para higiene permanente do local. O resultado clínico foi uma boa estética para o paciente. Geralmente não possui recidiva mediante cuidados no controle de higiene oral e hábitos.


Gingival recession is a relatively common complaint for patients seeking treatment due to sensitivity and esthetics. The authors report that the treatment of bilateral posterior gingival recessions is performed using the subepithelial connective tissue grafting. The operative technique used in this case was the Langer's method with coronary flap repositioning. There was a considerable increase regarding root coverage, suggesting repair process of the bilateral gingival recession with the interposition of connective tissue in the recipient area. In relation to clinical aspects, the Langer's technique is easier to be performed in relation to the esthetic aspect, coverage, and gains in height and thickness. The purpose of this paper is to report a clinical case to solve the gingival recession. The initial therapy consisted of oral hygiene instructions and root planning 30 days prior to surgery. Afterwards, the surgical procedures were performed accordingly. The graft was harvested from the palate and transplanted to the recession area to cover the areas of root exposure. After 14 days, sutures were removed and oral hygiene instruction was recommended. The clinical results were excellent in terms of esthetics. Generally, no relapse was observed after good oral hygiene and habits.

ABSTRACT

O objetivo deste trabalho foi relatar um caso clínico onde o planejamento reverso e o uso racional das cirurgias implantares e periodontais mostraram-se fundamentais no preparo para reabilitação da zona estética com coroas cerâmicas e metalocerâmicas. Uma paciente de 32 anos apresentava estética pobre, como ausências dentárias isoladas e perda de tecido mole/duro na região dos caninos superiores. O tratamento foi dividido em cinco etapas: 1) coroas provisórias e correção do plano oclusal e corredor bucal; 2) expansão da crista do rebordo e implantes conexão cone-morse/platform-switching (em dois estágios); 3) gengivoplastia; 4) reabertura e cirurgias gengivais (gengivectomia, enxerto ósseo/de tecido conjuntivo, divisão de papilas); e 5) condicionamento e colocação das coroas cerâmicas defi nitivas nos dentes (cimento resinoso) e metalocerâmicas (cimento fosfato de zinco) sobre os implantes. O desenvolvimento deste caso está baseado no uso da biomecânica de interface implante/pilar que confere os menores valores de reabsorção óssea ao longo do tempo, fornecendo restaurações definitivas com aspecto natural, e ainda apoiado por uma revisão sistemática demonstrando a eficácia do tecido conjuntivo subepitelial no aumento da largura queratinizada ao redor dos implantes. A finalização obtida é esteticamente aceitável e durável, muito desejável na região anterior da maxila.


The objective of this study was to report a case where the reverse planning and the rational use of implant and periodontal surgical protocols were fundamental to prepare the rehabilitation in the esthetic zone with all-ceramic and metalloceramic crowns. A 32 years-old patient had poor aesthetics, single-tooth defi cits, and soft/hard tissue losses in the region of the upper canines. After a concise planning, the treatment was divided into fi ve steps: 1) temporary crowns, correction of occlusal plane and buccal corridor; 2) ridge expansion, morse cone/platform-switching dental implants (two-stage procedure); 3) gingivoplasty; 4) implant exposure and gingival surgeries (gingivectomy, bone graft/connective tissue grafts, pedicle flaps); and 5) tissue conditioning and cementation of all-ceramic (resin cement) over teeth and metalloceramic (zinc phosphate cement) over the implant abutments. The development of this case is based on the use of a biomechanical implant interface/abutment which gives lower values of bone resorption over time, providing final restorations with a natural aspect, and still supported by a systematic review demonstrating the effectiveness of subepithelial connective tissue grafts to increase the width of the keratinized peri-implant mucosa. The outcome is esthetically acceptable and has long-term quality, a very desirable condition in the anterior maxilla.

ABSTRACT

INTRODUÇÃO Esta revisão qualitativa da literatura analisou publicações científicas internacionais sobre possíveis alterações miofuncionais orofaciais em pacientes acometidos pela Síndrome de Parry-Romberg, por meio da base de dados PubMed. MÉTODOS: O levantamento realizado limitou-se a seres humanos, de qualquer faixa etária, no idioma inglês, entre os anos 2002 e 2012. As publicações sem acesso completo, repetidas por sobreposição das palavras-chave, revisões de literatura, cartas ao editor e as não relacionadas diretamente ao tema foram excluídas. RESULTADOS: Foram identificados 719 estudos, sendo 21 dentro dos critérios estabelecidos. Com base nos estudos selecionados, pacientes acometidos pela Síndrome de Parry-Romberg podem apresentar alterações dos tecidos mole e duro, tais como atrofia dos músculos esternocleidomastoideo, masseter e pterigoideos; atrofia na região da bochecha e depressão da prega nasolabial; desvio dos lábios e nariz; atrofia unilateral da língua; atrofia do ângulo da boca; reabsorção progressiva do osso da maxila e da mandíbula; atrofia do arco zigomático, do osso frontal e assimetria facial; desenvolvimento atrófico das raízes ou reabsorção patológica dos números de dentes permanentes; redução da mandíbula e erupção atrasada dos dentes superiores e inferiores. CONCLUSÃO: Apesar do crescente interesse pelo diagnóstico e pela descrição sintomatológica de indivíduos com Síndrome de Parry-Romberg, a escassez de publicações que abordem tratamentos funcionais e interdisciplinares é evidente. Verifica-se a necessidade da realização de estudos mais específicos que visem à melhoria da qualidade de vida desses pacientes.


INTRODUCTION This qualitative literature review analyzed international scientific publications on possible orofacial myofunctional alterations in patients with Parry-Romberg syndrome by using PubMed. METHODS: The survey was conducted in English, between 2002 and 2012, and was limited to human beings of any age. Publications without full access, duplicated by overlapping keywords, literature reviews, letters to the editor, and those not directly related to the research topic were excluded. RESULTS: We identified 719 studies, of which 21 were within the established criteria. Based on the selected studies, patients with Parry-Romberg syndrome may show changes in soft and hard tissues such as atrophy of the sternocleidomastoid, masseter, and pterygoid muscles; atrophy in the cheek region and depression of the nasolabial fold; deviation of the lips and nose; unilateral tongue atrophy; atrophy of the mouth angle; progressive resorption of the maxilla and mandible bone; atrophy of the zygomatic arch and frontal bone, and facial asymmetry; atrophic root development or pathological resorption of permanent tooth numbers; and jaw reduction and delayed eruption of the upper and lower teeth. CONCLUSION: Despite the growing interest in the diagnosis and symptomatic description of individuals with Parry-Romberg syndrome, publications that address functional and interdisciplinary treatments are scarce. Therefore, specific studies aimed at improving the quality of life of these patients are needed.

ABSTRACT

O objetivo deste relato de caso clínico foi recuperar a estética da região do elemento 23. Foi utilizada uma técnica cirúrgica de alta previsibilidade associada à colocação de um componente protético mais estético. Paciente do gênero feminino, 32 anos, com implante já instalado, apresentou uma condição estética insatisfatória relacionada à reabilitação provisória e a transparência da margem peri-implantar. O implante apresentava uma inclinação vestibular de 17 graus. O plano de tratamento incluiu a manutenção do implante, porém, o pilar de titânio foi substituído por um pilar personalizado em zircônia, associado ao enxerto de tecido conjuntivo pela técnica de Raetzke. O procedimento realizado atingiu o objetivo inicial de recuperar a estética do tecido peri-implantar. O resultado da reabilitação final promoveu satisfação a paciente bem como mostrou ser uma alternativa efetiva nos casos de estética peri-implantar comprometida na região anterior


The aim of this case report was to recover the aesthetics of the area of teeth 23. A high predictable surgical technique was used associated with the placement of a more aesthetic prosthetic component. Female patient, 32 years with the implant already installed, presented poor aesthetic condition related to temporary rehabilitation and transparency of the peri-implant margin. The implant presented a buccal inclination of 17 degrees. The treatment included the maintenance of the implant, however, the titanium pillar was replaced by a custom zirconia abutment associated with a connective tissue graft by Raetzke technique. The procedure performed reached the initial goal of recovering the aesthetics of the peri-implant tissue. The result of the rehabilitation promoted patient' satisfaction as well as showed to be an effective alternative to the cases of peri-implant compromised aesthetics in anterior region

ABSTRACT

Soft tissue augmentation is a process of implanting tissues or materials to treat wrinkles or soft tissue defects in the body. Over the years, various materials have evolved to correct soft tissue defects, including a number of tissues and polymers. Autogenous dermis, autogenous fat, autogenous dermis-fat, allogenic dermis, synthetic implants, and fillers have been widely accepted for soft tissue augmentations. Tissue engineering technology has also been introduced and opened a new venue of opportunities in this field. In particular, a long-lasting filler consisting of hyaluronic acid filler and living human mesenchymal cells called "injectable tissue-engineered soft tissue" has been created and applied clinically, as this strategy has many advantages over conventional methods. Fibroblasts and adipose-derived stromal vascular fraction cells can be clinically used as injectable tissue-engineered soft tissue at present. In this review, information on the soft tissue augmentation method using the injectable tissue-engineered soft tissue is provided.

ABSTRACT

Soft tissue filler injection has been a very common procedure worldwide since filler injection was first introduced for soft tissue augmentation. Currently, filler is used in various medical fields with satisfactory results, but the number of complications is increasing due to the increased use of filler. The complications after filler injection can occur at any time after the procedure, early and delayed, and they range from minor to severe. In this review, based on our experience and previously published other articles, we suggest a treatment algorithm to help wound healing and tissue regeneration and generate good aesthetic results with early treatment in response to the side effects of filler. Familiarity with the treatment of these rare complications is essential for achieving the best possible outcome.

ABSTRACT

INTRODUÇÃO: A técnica de lipoaspiração recebeu várias contribuições desde sua primeira descrição, como modificações nas cânulas, variação na concentração da solução de infiltração e uso de aparelhos com tecnologias variadas. A utilização de aparelhos com tecnologia laser vem contribuir com o procedimento por meio da lipólise e com o estímulo de retração cutânea. Neste artigo é apresentada a experiência dos autores com a laserlipólise em 400 pacientes, no intervalo de 5 anos, sendo discutidos aspectos dos princípios da tecnologia e sua ação sobre os tecidos. MÉTODO: Estudo realizado entre julho de 2007 e julho de 2012, que incluiu 400 pacientes submetidos a procedimento de laserlipólise. Os procedimentos foram realizados seguindo protocolo original, com infiltração de soro gelado, passagem da cânula com fibra óptica para a condução da energia laser visando à laserlipólise, retração cutânea e, por último, lipoaspiração convencional. RESULTADOS: O período de internação variou de cirurgia em regime ambulatorial a pernoite. Cerca de 45% (180/400 pacientes) dos pacientes evoluíram com equimoses mínimas, com acometimento de 2% ou mais da superfície corporal comprometida. Os casos de hematoma, seroma e deiscência totalizaram 9% (36/400 pacientes). Em nenhum caso foi constatada queimadura por lesão térmica na pele. CONCLUSÕES: O procedimento de laserlipólise realizado com a técnica descrita demonstrou segurança e reprodutibilidade.


INTRODUCTION: Liposuction has undergone several improvements since its first description, including changes in the cannulas, variation in the concentration of the infiltrating solution, and the use of different devices and technologies. The use of laser technology devices for lipolysis and stimulation of skin retraction has contributed to the procedure. This article presents the authors' experience with laser lipolysis in 400 patients, within a 5-year period, and discusses the principles of the technology and its effect on tissues. METHODS: This is a study performed between July 2007 and July 2012 and included 400 patients who underwent laser lipolysis. All procedures were performed following the original protocol - infiltration of cold saline, passage of the cannula with an optic fiber for conducting the energy needed for laser lipolysis, skin retraction, and finally, conventional liposuction. RESULTS: Hospitalization type ranged from outpatient to overnight surgery. Approximately 45% (180 of 400) of patients had minimal bruising, with involvement of 2% or more of the affected body surface. Hematoma, seroma, and dehiscence occurred in a total of 9% (36 of 400) of patients. We did not find any case of thermal burn of the skin. CONCLUSIONS: Laser lipolysis performed according to the described technique was safe and reproducible.

ABSTRACT

OBJETIVO: Investigar os efeitos da remoção da adventícia da aorta em suínos. MÉTODOS: O experimento foi realizado com oito suínos. Removeu-se a camada adventícia da aorta descendente. Após a eutanásia com duas, quatro, seis e oito semanas, o segmento aórtico era removido. Após, eram feitos cortes histológicos com a coloração de hematoxilina e eosina (HE) e pelo método de Weigert - Van Gieson. RESULTADOS: Após duas semanas identificou-se um leve desarranjo do terço externo da túnica média. Nos animais sacrificados após quatro semanas observou-se um desarranjo estrutural dos terços externos da túnica média. Após seis semanas observou-se necrose da parede aórtica. Finalmente, após oito semanas além da fibrose da parede aórtica identificou-se a destruição da lâmina elástica interna. CONCLUSÃO: A remoção da adventícia da aorta em suínos levou à alterações degenerativas da média, determinando perda da estrutura da parede aórtica que é variável em sua localização, intensidade e forma, dependendo do tempo a partir do qual se estabeleceu a lesão isquêmica.


OBJECTIVE: To investigate the effects of removal of the adventitia on the tunica media in a pig model. METHODS: The experiment was performed in eight pigs. The adventitia of the descending aorta was removed. Following euthanasia, at two, four, six and eight weeks, the aortic segment was removed. Next, slices of the aorta were stained with hematoxylin and eosin (HE) and Weigert - Van Gieson. RESULTS: After two weeks there was a slight cellular breakdown in the outer third of the media. After four weeks structural breakdown of elastic fibers was observed in the outer two thirds of the same layer. In six weeks, several areas of necrosis and almost complete disruption of elastic fibers were identified. Finally, after eight weeks, there was fibrosis of the entire wall with disruption of the internal elastic lamina. CONCLUSION: The removal of the adventitia leads to degeneration of the media, determining loss of the normal structure of the aortic wall that is variable in its location, intensity and shape, depending on the length and duration of the ischemic insult.

ABSTRACT

O objetivo desse trabalho é relatar um caso clínico de recobrimento gengival utilizando retalho deslocado lateral associado a enxerto de conjuntivo para recobrimento de recessão gengival classe III de Miller. Relatou-se o caso de um paciente, gênero masculino, 45 anos, com Periodontite Crônica Grave localizada, escovação e oclusão traumáticas na região do elemento 41, apresentando retração classe III de Miller, ultrapassando a linha muco gengival, próximo ao ápice radicular, giroversão, extrusão e perda óssea interproximal. Inicialmente, foram realizados procedimentos básicos periodontais. No procedimento cirúrgico, utilizou-se retalho deslocado lateral associado a enxerto de conjuntivo, aplainamento radicular com brocas diamantadas Perioset®, raspagem e alisamento radicular com curetas gracey 5-6, e cloridrato de tetraciclina (125mg/ml) por 3 minutos. Utilizou-se suturas reabsorvíveis para fixação do enxerto ao periósteo e suturas externas com fio seda 4.0. Após a cirurgia, realizou-se o ajuste oclusal. Foi obtido aproximadamente 80% de recobrimento da recessão gengival com o emprego da referida técnica, aliado a uma diminuição significativa da profundidade e sangramento à sondagem e mobilidade, compatível com saúde clínica periodontal. Conclui-se que apesar da baixa previsibilidade dos resultados cirúrgicos para a terapêutica proposta, obtive-se um recobrimento radicular satisfatório.

ABSTRACT

The frenum exerts a pull upon the tissue and can lead to the continuation of the lesion, and the keratinized tissue provides increased resistance to the periodontium. Various techniques have been used to deepen the vestibule and increase the keratinized mucosa. However, there is no case report on correcting the frenal pull and increasing the keratinized mucosa around dental implant using denudation procedure. This article presents a case of frenal pull that was corrected with denudation procedure with the incision line within the keratinized tissue.

ABSTRACT

PURPOSE: To evaluate long-term visual outcome of arteriovenous adventitial sheathotomy in BRVO-induced macular edema. METHODS: The visual outcomes of 8 patients following vitrectomy with arteriovenous adventitial sheathotomy for BVO-induced macular edema (surgery group) were retrospectively evaluated. The three-year post-operative visual acuity of the surgery group was compared with that of the conservatively managed controls. RESULTS: All patients were followed for a minimum of 36 months. Mean BCVA (logMAR) in the surgery group changed from 1.10+/-0.34 to 1.19+/-0.70 and to 0.80+/-0.36 at 12 and 36 months, respectively (p=0.959 at 12 months, p=0.018 at 36 months). In the control group, visual acuity improved from 1.15+/-0.43 to 0.43+/-0.44 and to 0.43+/-0.39 at 12 and 36 months, respectively (p=0.015 at 12 months, at p=0.003 at 36 months). A strong trend toward better visual acuity at 12 months and final examination was observed for controls. (surgery vs. control group, p=0.052 at 12 months, p=0.066 at 36 months). CONCLUSIONS: Considering the favorable natural course of BVO and the unproven effect of reperfusion on macular edema, surgical efficacy of arteriovenous adventitial sheathotomy requires further evaluation.

ABSTRACT

A técnica do retalho dobrado foi desenvolvida por Abrams, em 1980, com a finalidade de corrigir defeitos apresentados na vestibular de rebordos edêntulos. Apresenta como vantagens: aspecto gengival estético; previsibilidade porque o enxerto mantém conexão e recebe suprimento sanguíneo e, é realizado em apenas um ato cirúrgico, ao contrário das técnicas do enxerto em envelope e do enxerto onlay. O enxerto dobrado foi idealizado para utilização em regiões desdentadas que irão receber próteses fixas. O propósito deste trabalho é mostrar a utilização da técnica do enxerto dobrado numa região que recebeu implante e apresenta depressão na região vestibular do incisivo central superior direito.


The technique of the folded graft was developed by Abrams in 1980, with the purpose to correct defects presented in the vestibular contest of edentulous rims. It presents as advantages: aesthetic gengival aspect; previsibility because the graft keeps connection and receives blood suppliment, and is made in one surgical act, against the techniques of submucosal graft and onlay graft. The folded graft was idealized for use in edentulous regions that will go to receive fixed prosthesis. The intention of this work is to show the use of the technique of folded graft in a region that receives implantation, however presents depression in the upper right central incisor's area.

ABSTRACT

A concavidade no rebordo alveolar dificulta a estética em próteses sobre os implantes e, freqüentemente dá a impressão de que estas próteses estão sobre o topo do rebordo, pois as eminências que existiam no processoalveolar da maxila que recobriam as raízes desapareceram com as perdas das mesmas. O objetivo deste trabalho é relatar um caso clínico cirúrgico com enxerto de conjuntivo no rebordo alveolar da maxila para melhorar a emergência em implantes osseointegrados

ABSTRACT

No clinical trial has been done in relation to successful coverage of gingival recessions with and without odontoplasty. This study was designed to evaluate the effects of odontoplasty with subepithelial connective tissue graft [SeCTG] on the outcome of root coverage on abraded teeth with gingival recessions, attachment level, height of keratinized gingival and teeth sensitivity. Thirty-six class I, and III Miller recessions were treated in 10 patients, using SeCTG with coronally positioned flap with [test group] and without [control group] odontoplasty. Clinical measurements probing depth, abrasion depth, height of recession [HR], width of recession [WR], height of keratinized gingival [KG], clinical attachment level [CAL], width of interdental papilla, bone level and vestibule depth were recorded at base line and 3 months after surgery. The changes in variables were evaluated by paired t test and Wilcoxon's sign ranked test. Probing depth before and after surgery was reduced 0.44 mm in the test group which was not statistically significant. However the difference was significant in the control group [P=0.007]. Differences between mean clinical attachment level [CAL], height of recession [HR], width of recession [WR] and height of keratinized gingival [KG] in test and control groups before and after surgery were statistically significant [P<0.0001]. Differences between the two groups in CAL, and HR were statistically significant [P=0.026, P=0.03]. Difference between mean two groups in KG before surgery was statistically significant [P=0.036]. However difference between two groups was not statistically significant. Difference between before and after surgery in vestibule depth was not statistically significant. Interdental papilla in test group had not any relation with mean root coverage, however in control group the relation was highly significant [P=0.001, r=0.75]. Bone level in mid facial in both groups had not significant relation with mean root coverage. Abrasion depth in test group had not significant relation with mean root coverage. However, in control group, had significant relation with mean root coverage [p=0.003, r =0.65]. SeCTG with coronally positioned flap is a predictable method for root coverage with shallow, moderate and deep recessions. Odontoplasty in abraded teeth in order to decrease avascular surfaces, irregularities and root convexity results in better clinical outcome to gain clinical attachment, root coverage and keratinized gingiva

ABSTRACT

O recobrimento de raízes desnudas constitui-se em um dos desafios do tratamento periodontal. Dentre as várias técnicas propostas para este fim está o retalho posicionado lateralmente, que, além de sofrer várias modificações desde os primeiros relatos, passou a ser associado a outras técnicas, como o enxerto de tecido conjuntivo subepitelial. Relataremos um caso clínico de uma paciente do género feminino, 41 anos, que apresentava recessão gengival Classe II de Miller na face vestibular do dente 45. A paciente tinha como queixa principal a presença de hipersensibilidade dentinária. Realizaram-se exames clínico e radiográfico e diagnosticou-se como causa principal a presença de inflamação gengival pela presença de placa bacteriana. Após o tratamento periodontal básico, realizou-se cirurgia com o objetivo de recobrimento radicular. Como a área adjacente à recessão apresentava uma boa quantidade de gengiva inserida e ausência de perda óssea interproximal, a técnica cirúrgica de escolha foi o retalho posicionado lateral associado ao enxerto de tecido conjuntivo subepitelial. Nas avaliações pós-operatórias, observou-se um completo recobrimento radicular, aumento da faixa de gengiva ceratinizada, ausência de hipersensibilidade dentinária e um ótimo resultado estético.

ABSTRACT

This paper reviews in details aspects of reported creeping attachment in the literature and in addition reports a clinical case with detailed descriptions and follow-up period of one year. The case report describes a creeping attachment that developed after using free connective tissue graft to treat a gingival recession on the lower left central incisor. Most of the cases on creeping attachment were reported in literature following free gingival grafts and submerged connective tissue grafts. To the author's knowledge, this type of creeping attachment using purely free connective tissue graft has not been previously reported in the dental literature. The developed creeping attachment in this case displayed a similar way of healing events that had been reported following free gingival grafts

ABSTRACT

PURPOSE: To determine safety, clinical and visual results, and potential complications of early radial optic neurotomy (RON) surgery in eyes with central retinal vein occlusion (CRVO), with relative afferent pupillary defect and visual acuity MATERIALS AND METHODS: This prospective, interventional case-series included 24 patients of CRVO who underwent RON within 2 months of disease onset. The preoperative examination included slitlamp biomicroscopy, fundus photography and fluorescein angiography. Foveal thickness was measured using optical coherence tomography (OCT) in the last 6 eyes only. In each case, RON was performed after informed consent. Two radial incisions were placed in the nasal quadrant of the optic disc, using a micro-vitreoretinal blade. The postoperative change in vision, clinical picture, fundus photographs, angiograms and foveal thickness by OCT were the main outcome variables studied. The Wilcoxan signed test was used to assess the results. RESULTS: Average symptom duration was 37.8 +/- 15.2 days (range 15-60 days, median: 34.5 days) and follow-up 7.7 +/- 2.1 months (range 1-12 months, median: 8 months). Visual outcome: 2 (8.33%) eyes each had fall and preservation of pre-RON visual acuity respectively. Twenty eyes (83.33%) showed increase in vision (of average 3 lines). Pre and postoperative vision ranged from 0.017-0.1 (average:0.061) and 0.017-0.667 (average: 0.17) respectively (P < 0.05). Clinical and angiographic outcome: decline in macular oedema, decreased or resolved intraretinal haemorrhages, resolution of venous dilatation and disc oedema could be appreciated in all cases. Foveal thickness: average pre and postoperative foveal thickness was 834.17 microm and 556.17 microm respectively (P < 0.05) in the 6 eyes where it was measured before and after RON. One eye developed retinal-detachment. CONCLUSION: Radial optic neurotomy is better than the natural course in eyes with CRVO, with vision < 6/60.
