Resumo: O presente estudo foi desenvolvido com o objetivo de avaliar as características pós-operatórias de superfícies radiculares expostas tratadas com enxerto de tecido conjuntivo, com duas técnicas de fixação do enxerto. O estudo envolveu 42 pacientes, que de maneira randomizada constituíram dois grupos iguais de estudo, denominados teste e controle, com 21 pacientes em cada um deles. No grupo teste o enxerto foi fixado ao leito receptor com adesivo de fibrina derivado de veneno de serpente e no grupo controle a fixação dos tecidos foi realizada com fio de sutura poligalactina 910. A idade dos pacientes variou entre 19 e 49 anos e estes apresentavam defeitos de recessão gengival incluídos nas classes I e II de Miller. Os controles foram realizados avaliando-se parâmetros clínicos tais como: tempo cirúrgico, tempo de hemostasia, presença de eritema, alteração de hálito e sabor, grau de recobrimento radicular, altura da recessão, profundidade de sondagem vestibular, nível de inserção clínica, índice de placa, índice gengival, quantidade de gengiva inserida, mucosa ceratinizada e a estética, com registros no momento pré-operatório, trans-operatório e aos 7, 14, 21, 30, 60 e 90 dias de pós-operatório. A análise comparativa entre o momento inicial e o final em cada um dos grupos mostrou resultados estatisticamente significantes, com melhores resultados ao término do estudo para todas as variáveis estudadas. Ao final do estudo, observamos entre os grupos, resultados estatisticamente significantes para as variáveis; tempo cirúrgico, quantidade de gengiva inserida e profundidade de sondagem vestibular, com melhores resultados nos pacientes do grupo teste. Com as demais variáveis não foram observadas diferenças significantes, inclusive para a estética alcançada.
Abstract: The present study aimed to evaluate the postoperative characteristics of exposed root surfaces treated with connective tissue graft, with two different techniques to fix it. The study involved 42 patients, randomly of two equal groups named test and control, each one with 21 patients. In the test group, the graft was fixed to exposed root surfaces with fibrin adhesive derived from serpent venom and in the control group this graft was accomplished with a conventional suture. The age of the patients ranged between 19 and 49 years old and they presented this defect named Millerþs class I and II. Controls were carried out by assessing clinical parameters such as: surgical time, hemostasis time, presence of erythema, breath and taste alteration, root coverage degree, recession height, vestibular probing depth, clinical insertion level, plaque index, gingival index, amount of attached gum, keratinized mucosa and aesthetics, with records at preoperative and trans-operative moments and at 7, 14, 21, 30, 60 and 90 days, postoperatively. The comparative analysis between the initial and final moments in each group showed statistically significant results, with the best results at the end of the study for all variables studied. Statistically significant results were observed at the end of the study between the groups only for the following variables; surgical time, amount of attached gum and vestibular probing depth, with the best results for patients in the test group. Significant differences were not observed in the remaining variables, including aesthetics. This study concluded that the fibrin adhesive derived from serpent venom presented favorable characteristics when applied in periodontal surgery for root coverage in recessions of marginal tissue, Millerþs Class I and II, as a suture substitute.

Full textL’objectiu del present estudi es comparar el guany de volum al voltant d’implants dentals després d’haver utilitzat aleatoriament injert de teixit conectiu subepitelial de paladar o de tuberositat. L’àrea donant més utilitzada per realitzat procediments d’augment gingival ha estat sempre la zona del paladar. Tot i que estudis recents han demostrat que la zona de la tuberositat pot ser una bona alternativa degut a que pot tenir millors propietats per l’augment gingival. S’ha demostrat darrerament que el teixit conectiu de la tuberositat és més dens i conté menys teixit gras i glandular. Això pot comportar que aquest teixit no es contraigui tant i que per tant pugui aconseguir millors resultats en quant a guany de volum. En aquesta investigació 32 pacients portadors de 35 implants amb defecte de volum vestibular han rebut cirugía d’augment de teixit tou utilitzant injert de teixit conectiu de paladar o tuberositat. S’han realitzat mesures utilitzant un escáner intraoral a l’inici de l’estudi i 3 mesos després. També s’ha realitzat estudi histològic i d’immunohistoquímica de 20 mostres. Com a conclusió, els dos grups de l’estudi han aconseguit guanyar volum de teixit tou als 3 mesos. No s’han detectat diferencies estadísticament significatives entre els grups. Tot i així s’ha observat una tendencia a millors resultats en el grup de pacients que han rebut injert de teixit tou de la tuberositat.

Os implantes dentários têm sido utilizados desde meados da década de 50, e inúmeros estudos garantem a confiabilidade para sua utilização, dessa forma o implante tem se tornado uma prática comum entre os cirurgiões dentistas. À medida que sua utilização vem crescendo, suas complicações também aumentaram, principalmente quando instalados em áreas estéticas, onde há deficiência de tecido conjuntivo perimplantar. O objetivo deste estudo clínico controlado randomizado foi avaliar o aumento do volume de tecido conjuntivo perimplantar em implantes instalados em áreas estéticas com a utilização de enxerto de tecido conjuntivo. Para este estudo, foi utilizada uma amostra de 42 indivíduos com necessidade de implantes em áreas estéticas, onde o grupo teste (n=20) recebeu enxerto de tecido conjuntivo sobre os implantes e o grupo controle (n=22) recebeu apenas o implante dental sem a colocação de enxerto de tecido conjuntivo. Para análise do aumento do tecido perimplantar foram realizadas medidas clínicas no baseline, trans-operatório e pós-operatório de 4 meses. Após 4 meses o grupo teste apresentou diferença significativa no aumento de tecido conjuntivo, uma média 3,35±1,08mm / 3,62±1,08mm na vestibular e sobre o rebordo respectivamente, quando comparado ao grupo controle 2,08±0,62mm/ 2,51±0,53mm na vestibular e sobre o rebordo respectivamente. Houve diferença significativa na diminuição da deiscência óssea vestibular para o grupo teste uma média de 0,4±0,8mm contra 1,0±0,8mm do grupo controle (p<0,05). Não houve diferença significativa quanto a dor relatada pelos pacientes e a quantidade de analgésicos ingeridos. Pode-se concluir que após 4 meses o grupo teste apresentou aumento no volume de tecido conjuntivo, diminuição da deiscência óssea vestibular e os pacientes do grupo teste não sentiram uma dor maior que o grupo controle.
Dental implants have been used since 1950, and as numerous studies ensure reliability for its use, they implant have become a common practice among dentists. However , complications have also risen from its increased application, especially when they are installed in esthetic areas, where there is deficiency of periimplant soft tissue. The purpose of this randomized controlled trial was to evaluate the increase in volume periimplantar soft tissue esthetic areas with the use of connective tissue graft. Individuals in need of implants in esthetic areas were included, and divided in two groups: test group (n = 20) received a tissue graft over the implants and the control group (n = 22) received only dental implant without the connective tissue graft placement. For the analysis of periimplantar tissue augmentation, baseline, trans-operative and postoperative measurements were performed. After 4 months, the test group presented a significant difference in mean connective tissue augmentation, with 3.35 ± 1.08 mm in the vestibular area and 3.62 ± 1.08 mm on the ridge when compared to the control group, with 2.08 ± 0 62 mm in the vestibular area and 2.51 ± 0.53mm on the ridge. There was a significant difference in the reduction of vestibular bone dehiscence for the test group, with a mean of 0.4 ± 0.8 mm versus 1.0 ± 0.8 mm in the control group (p <0.05). There was no significant difference in pain reported by patients and the amount of post-operative analgesics ingested taken. It can be concluded that after 4 months the use of connective tissue graft test group resulted in an increase in connective tissue volume, decreased vestibular bone dehiscence with similar amount of post-operative pain than the control group.

Full textBackground: The aim of this study was to evaluate the root coverage obtained by two different periodontal plastic techniques in severe smokers, analyzing clinical, laboratorial and histological parameters. Methods: Twenty severe smokers were selected. Each patient had bilateral Miller class I or II gingival recessions in non-molar teeth. Clinical measurements of probing pocket depth (PPD), clinical attachment level (CAL), recession height (RH) and recession width (RW), keratinized mucosa height (KMH) and keratinized mucosa thickness of (KMT) and height and width of the adjacent papillae were determined at baseline, 3 and 6 months. One side received coronally positioned flap, while the other side received the extended flap technique, both procedures in conjuction with the subeptelial connective tissue graft (SCTG). Biopsies from SCTGs and flaps were prepared for immunohistochemistry. Blood vessels were identified and counted by coexpression of Factor-VIII related antigen stained endothelial cells. Salivary cotinine samples were taken at baseline and after 3 and 6 months, as an indicator of the level of exposure to nicotine. Results: Between groups or intra groups analysis showed no statistical differences for the evaluated clinical parameters. Patients maintained the same exposure to smoke during the 6 months evaluation periods. Both techniques had low root coverage (standard technique: 43.18% and test technique: 44.52%). Histomorphometry of biopsies revealed blood vessel densities of 13.49 ± 5.48 vessels/200x field for the flaps, and of 18.69 ± 4.87 vessels/200x field for the grafts (p = 0.0001). Conclusion: The extend flap technique did not differ from standart technique for recession treatment of severe smoking patients.

Full textDifferent surgical techniques have been proposed for root coverage, showing varying results, especially in areas of extense recessions. The aim of this study is to evaluate the effectiveness of the newly forming bone technique (NFB) as an alternative treatment of Millers class I or II recessions. Both gender patients aged 18-45 years presenting at least one site with recession >4 mm and one condemned tooth or edentulous ridge allowing the surgical creation of an alveolus (test group) were selected. The sample was divided into two groups, according to the root coverage procedure: test (n=35) - NFB and control (n=30)- subepithelial connective tissue graft (SCTG). Clinical examinations were performed by a single trained examiner at baseline and 1, 3, 6 and 9 months after surgery according to probing depth (PD), clinical attachment level (CAL), recession (R), bleeding on probing (BOP), plaque index (PI) and keratinized gingiva width (KG). The analysis by t test have shown that both techniques are effective in the reduction of recession (-2,77±0,16 x - 3,20±0,24; p=0,14). The NFB technique was more effective in the reduction of PD (-0,85±0,10 x 0,24±0,12; p<0,0001), BOP (-0,65±0,21 x 0,00±0,13; p=0,01), PI (-1,57±0,25 x 0,43±0,31; p<0,0001) and gain of CAL (-3,74±0,26 x - 2,95±0,19; p=0,024), but less effective in the increase of KG width (0,48±0,13 x 1,43±0,17, p<0,0001). Intra-group analysis showed a significant improvement of all clinical parameters (p<0,05; ANOVA) for both groups, except for PI (p=0,4267), BOP (p=2,19) and PD (p=1,05) in control group. These results suggest that the NFB technique is effective to the treatment of large recession defects, allowing the reduction of recession and, possibly, regeneration of periodontal tissues.

Full textThe aim of this study was to compare the 6 months outcome of root coverage, dentin hypersensitive, pain after surgery and aesthetics using the modified coronal advanced flap (mCAF) associate with connective tissue graft (CTG) or collagen matrix (CM) in the treatment of gingival recession (GR). Fifteen patients with superior multiple recessions in canines and pre-molars were selected for this non-inferority randomized clinical trial, which was divided in control group (mCAF+CTG) and test group (mCAF+CM). The residual GR (primary outcome) was lower for control group (0,3 ± 0,6 mm) comparing with test group (0,6 ± 1,0 mm) (p = 0,008). The root coverage percentage was 89,3% for control group and 77,7% for test group. Both groups demonstrated gain of keratinized tissue in 6 months (p < 0,05) statically different between groups (p = 0,031). The probing depth and gain of clinical attachment level were similar between the groups in all evaluated periods. Dentin hypersensitive was reduced in all groups. The pain after surgery was higher in control group comparing with test group. Aesthetic satisfaction evaluated by patient and periodontist was high independently of group with no statistical difference, however, the scar formation at papillae base and visual differences were visually higher using mCAF+CTG. Considering the clinical outcomes balanced with patient related outcomes and aesthetic satisfaction, the use of mCAF+CM is a alternative to mCAF+CTG in the treatment of multiple gingival recession.

Full textThere are few randomized controlled clinical trials mentioning the oral health-related quality of life (OHRQoL) effect and morbidity in treatments of multiple gingival recession coverage. This study aims to compare the OHRQoL and morbidity in two groups of patients: A. surgical intervention with connective tissue graft (CTG) removed from the palate; B. surgical intervention using a collagen matrix (CM - no graft from the palate) in the treatment of multiple gingival recessions. Methods: A split-mouth randomized clinical trials was conducted. Fifteen patients with bilateral multiple recessions in maxillary canines and pre-molars were selected. Quality-of-life was assessed by the Oral Health Impact Profile-14 (OHIP-14) questionnaire through multinível regression. The morbidity included pain, quantify of medication, healing and inflammation/edema. Parameters were evaluated at baseline, 7, 15, 30, and 180 days. Results: OHIP-14 in 7 and 15 days showed better OHRQoL in CM group when compared with CTG (p=0,002 and p=0,001 respectively). Correlation was stablished in OHIP-14 subscales after treatment with CM: physical pain, psychological discomfort, physical disability, psychological disability, and handicap (p<0,05). There were statistically significant differences for pain and amount of medication, favoring CM group (p<0,05). Conclusion: This study shows that surgical treatment with CM for multiple gingival recessions Miller Class I was positively associated with psychological and physical impacts on patient\'s quality of life, when compared with CTG removed from the palate.

Nas últimas décadas tem aumentado o interesse pelos enxertos de pele humana radioesterilizadas, para aplicação principalmente em queimaduras extensas e profundas. Isto se deve ao fato destes enxertos apresentarem rápida aderência e menor potencial antigênico, em comparação com os demais tratamentos utilizados. A proposta deste estudo foi avaliar a histoarquitetura do enxerto de pele humana irradiada com doses de 25 kGy, 50 kGy e não irradiada, durante o processo de reparação tecidual, em camundongos Nude submetidos a enxertia de pele na região dorsal. Três grupos de animais receberam enxertos de pele humana irradiada (25 kGy e 50 kGy) e não irradiada e foram eutanasiados no 3º, 7º e 21º dia após a realização da cirurgia. Após os procedimentos histológicos de rotina, as amostras de tecido foram coradas com hematoxilina e eosina (HE) para a quantificação de queratinócitos, fibroblastos, células de defesa e vasos sanguíneos e a reação de imunofluorescência (IF) foi realizada para a determinação da expressão de colágeno do tipo I humano e do colágeno dos tipos I e III de camundongo. A quantificação, tanto das células quanto dos tipos de colágeno foi realizada por análise de imagem, utilizando o programa Image-Pro PLus 6.0. Os resultados histológicos demostraram que a pele humana irradiação, quando enxertada, influencia o aumento do número de células no local de cicatrização ao longo do tempo, principalmente na dose de 25 kGy, além de proporcionar uma melhor dispersão destas células. No 21º dia, os três grupos de animais com enxertia de pele humana tiveram parte do enxerto incorporado no processo de cicatrização. O grupo não irradiado apresentou maior incorporação do enxerto (43%), porém menor produção de colágeno do tipo III de camundongo (22%). Já os grupos com enxertia de pele irradiada apresentaram menor incorporação do enxerto (6 e 15%), mas com maior produção de colágeno do tipo III de camundongo (35% e 28%, para 25 kGy e 50 kGy, respectivamente). Com este estudo pôde-se concluir que o grupo irradiado a 25 kGy, apresenta maior proliferação celular e formação de vasos,além de melhor remodelamento da região de cicatrização.

Full textAim: This study aims to conduct a review on the efficacy of the use of a modified coronally advanced flap (MCAF) with a connective tissue graft (CTG) compared to MCAF and Mucograft (MG) in terms of complete root coverage (CRC), after a minimal 6-month follow-up in patients with maxillary multiple gingival recessions (MGR), and post-operative pain in patients that underwent CTG harvesting will be determined. CTG obtained from patients and also a soft tissue substitute (MG) implanted in mice at 15 and 30 days will also be histologically characterized. Material and Methods: A bibliographic review was conducted through an electronic and hand search. Eligibility of the resulting articles was assessed through title and abstract analysis and subsequently full-text-analysis by two independent reviewers. Primary (CRC) and secondary outcomes (recession reduction (RecRed) and keratinized tissue(KT) gain) were evaluated. Two patients with maxillary Cl I or II MGR on adjacent teeth that needed root coverage were included in this study. One underwent MCAF/CTG while the other MCAF/MG. Post-operative pain questionnaires were handed out to 6 patients that experienced CTG harvesting. Primary (CRC) and secondary (mean of root coverage (MRC) and post-operative pain) outcomes were evaluated at 6-months post-operative. Palatal biopsies of the CTG donor site were obtained for posterior histomorphometric evaluation, and MG was implanted subcutaneously in mice with subsequent histological evaluation at 15 and 30-days post-implantation. Results: After an extensive search, only 3 studies were included, in which 1 reported the use of MCAF/MG. The studies were only comparable at 12-months, where MCAF/CTG obtained a mean CRC value of 73.7% while MCAF/MG attained 88.1%. The patients that underwent MCAF/CTG and MCAF/MG responded well to the surgical treatment. Healing was uneventful and the 1-week post-operative pain was low in both approaches. At the 6-month evaluation, CRC was obtained in 75% of the treated sites with MCAF/CTG. Patients who underwent CTG harvesting, regardless of the surgical technique reported a low pain intensity that subsided by the fourth day after surgery. Five in six patients referred that both the donor and the receptor site hurt equally. Two palatal biopsies revealed tissue with a highly dense connective tissue, the lamina propria (LP), and tissue also dense in connective tissue but with a greater presence of adipose tissue, the submucosa (SM). The histologic evaluation of MG in mice showed a well-integrated membrane with increasing remodulating and formation of new vascular structures from 15 to 30 days. Conclusion: More studies with standardized outcomes and follow-ups are needed to determine which approach, MCAF/CTG or MCAF/MG, is more efficacious after 6-months post-operative. It can also not be assessed whether MCAF/MG will have the same tendency for a coronal shift of the gingival margin that MCAF/CTG has over time. A larger number of included patients with the same follow-up period would be necessary to draw conclusions about the CRC at 6-months post-operative. Low pain levels were reported and although the donor site may not necessarily be the cause of more pain, more investigation is needed with a larger amount of standardized patients. The palatal biopsies confirmed that the LP had dense connective tissue and enough thickness for its use as a CTG, while the SM had more adipose tissue, even if some variability was observed. The implanted MG revealed optimal integration, its bilayered structure acted as barrier for preferential tissue ingrowth.

Full textIntrodução: A cirurgia plástica periodontal tem evidenciado grandes progressos no sentido de solucionar os problemas estéticos e funcionais induzidos pelas recessões gengivais. Neste contexto, o recobrimento radicular com recurso a enxertos de tecido conjuntivo tem-se mostrado uma técnica viável e previsível para o tratamento de recessões gengivais classe I e II de Miller. Com a combinação da técnica de tunelização pretende-se melhorar o potencial vascular pela ausência de incisões de descarga verticais, procurando deste modo otimizar o resultado estético final. Objetivos: Avaliar a eficácia da técnica de tunelização com enxerto de tecido conjuntivo no recobrimento radicular de classes I e II de Miller e, adicionalmente, exemplificar a sua utilização através da apresentação de casos clínicos. Materiais e Métodos: Foi realizada uma revisão sistematizada da literatura, recorrendo a bases de dados eletrónicas primárias (PubMed) e secundárias (Cochrane, B-on e EbscoHost), tendo sido selecionados artigos de 2000 até 2012 em língua inglesa. Foi também efetuada uma pesquisa manual de artigos e livros disponíveis na biblioteca da Área de Medicina Dentária. Critérios de inclusão: todo o tipo de metodologia de estudos clínicos que referiam intervenções com enxerto de tecido conjuntivo utilizando a técnica de tunelização, com um follow-up de pelo menos 6 meses, em doentes com recessões classes I ou II. Critérios de exclusão: estudos pré-clínicos. Resultados: Foram selecionados 9 artigos (3 revisões sistemáticas, 1 estudo clínico controlado e 5 estudos clínicos não controlados). Conclusões: De acordo com os resultados obtidos, o enxerto de tecido conjuntivo é uma escolha viável no recobrimento radicular e quando associado à técnica de tunelização representa um tratamento promissor de recessões classes I e II. A sua associação tem alcançado uma melhoria significativa nos parâmetros clínicos periodontais, o que se traduz consequentemente no sucesso terapêutico. Segundo a literatura analisada, esta técnica minimamente invasiva está indicada para casos de recessões gengivais unitárias ou múltiplas adjacentes, principalmente em áreas estéticas. No entanto, são necessários estudos adicionais no sentido de avaliar o potencial desta técnica a longo prazo. Introduction: The periodontal plastic surgery has shown great progress in order to solve the functional and aesthetical problems induced by gingival recessions. In this context, the root coverage with connective tissue grafts has been a viable and predictable technique for the treatment of Miller’s class I and II gingival recessions. The connective tissue grafts combined with the tunnel technique aims to improve the vascular potential due to the absence of vertical releasing incisions, thus trying to optimize the aesthetic results. Objectives: The aim of this review is to evaluate the efficacy of the tunnel technique with connective tissue graft in Miller’s class I and II root coverage and also to demonstrate its use by presenting clinical cases. Materials and Methods: To systematize a review of the literature, primary electronic databases (PubMed) and secondary electronic databases (Cochrane, and B-on EbscoHost) were searched in order to select articles from 2000 to 2012 in English. Additional information was seeked by a manual search in articles and books available in the library of Area of Dentistry. Inclusion criteria: all kind of methodology of clinical studies that reported interventions with connective tissue graft using the tunnel technique, with a minimal follow-up period of 6 months in patients with class I or II recessions. Exclusion criteria: pre-clinical studies. Results: 9 articles were selected (3 systematic reviews, 1 controlled clinical study and 5 non-controlled clinical studies). Conclusions: Considering the obtained results, the connective tissue grafts proves to be a viable choice in root coverage and when combined with the tunnel technique it represents a promising treatment for class I and II recessions. This combination has led to a significant improvement in clinical periodontal parameters, which results in a subsequent successful treatment. According to the literature review, this minimally invasive technique is indicated in cases of single or multiple adjacent gingival recessions, particularly in aesthetic areas. However, further studies are needed to assess the long term potential of this technique.

Full textObjective: to analyze and compare the techniques of root coverage, namely CAF+SCTG/CTG, FGG and TUN+SCTG/CTG, and determine which is the technique with greater stability for long term for the treatment of gingival recessions. Methods: a review was performed using electronic databases such as, PubMed and BON, which included only clinical trials to compare the results of techniques, with a minimum follow-up of 3 years in the CAF+SCTG/CTG, FGG techniques, as long as there was insufficient long-term clinical evidence for tunneling, so 1-year follow-up studies were accepted. Results: 11 controlled clinical trials and 1 meta-analysis were obtained and analyzed comparing the values of the qualitative and quantitative parameters in the root coverage using CAF+SCTG/CTG, FGG and TUN+SCTG/CTG techniques. Clinical and aesthetic parameters evaluated in the studies were described. Conclusions: the interpretation of the results obtained concludes that FGG is a good technique for increasing KT, but does not offer optimal esthetics over time, but CAF + CTG emerges, which in the long term provides good a esthetics and good root coverage in cases of localized gingival recessions, while in cases of multiple gingival recessions the technique that offers the best results is TUN combined with CTG.

Full textIntroduction: Currently, Oral Implantology is one of the most important areas in Dentistry, which provides a wide choice of treatments for patients who are totally or partially edentulous. However, the use of immediate implants in the anterior or esthetic area is still a High risk, given the unpredictability of changes in the peri-implant tissues, such as bone tissue in which esthetic complications may occur due to gingival contour and architecture modification. Objectives: The aim of this systematic review was to analyze the effect of a connective tissue graft on the volume of peri-implant tissues when placing an immediate implant at the maxillary esthetic area. Materials and Methods: A systematic review was carried out, selecting articles with publication date until 15 April 2021, through the computer platforms MEDLINE/Pubmed, Sciencedirect and Cochrane Data base. The keywords “immediate implant”, “immediate implant placement”, “immediate implantation”, “dental implants”, “connective tissue graft” and “soft tissue graft” were used, together with the boolean operators AND and OR. The studies were analyzed and evaluated respecting the previously established inclusion and exclusion criteria. Results: 6 articles were selected, which included several parameters and variables. A higher Pink Esthetic Score (PES) value was evidenced in the test group compared to the control group, obtaining a value of 9.41,4 e 8.911,6, respectively. In terms of marginal bone loss (MBL), there was a greater loss in the test group, which was -0.0550,35mm, than in the control group, which was -0.040,36mm. Conclusion: Connective tissue grafting during the placement of immediate maxillary implants can be a viable option to maintain the contour of the periimplant soft tissue, obtaining an acceptable aesthetic result. In terms of marginal bone loss, the connective tissue graft insertion does not result in any advantage.

Resultados: Foram selecionados 4 artigos (2 séries de casos, 1 estudo clínico controlado e 1 estudo clínico controlado randomizado). Conclusões: A técnica de posicionamento coronário modificado com enxerto de tecido conjuntivo está associada a uma maior redução da altura das recessões gengivais iniciais, à aquisição de maior espessura de tecido queratinizado e a uma maior probabilidade de recobrimento radicular completo a longo prazo (5 anos), conferindo maior previsibilidade ao tratamento. Esta abordagem está indicada em casos de recessões gengivais múltiplas adjacentes, com particular relevância em áreas estéticas. A nível dos critérios estéticos, tanto no ponto de vista dos clínicos como dos doentes, permite alcançar resultados estéticos elevados. Introduction: The periodontal plastic surgery has shown great progress in order to solve not only functional problems induced by gingival recessions but also aesthetics. Root coverage procedures with connective tissue grafts have shown a high predictability in the treatment of Miller’s class I and II gingival recessions. Modified coronally advanced flap in combination with connective tissue graft presents an advantageous approach taking into account the final aesthetic result of multiple gingival recession-type defects treatment. Objectives: The aim of this review is to evaluate the effectiveness of the modified coronally advanced flap with connective tissue graft in Miller’s class I and II root coverage exemplifying its use by presenting two clinical cases. Material and Methods: Primary electronic databases (PubMed) and secondary electronic databases (Cochrane Collaboration and B-on) were searched in order to select articles published from 2000 to 2014 in English. Inclusion criteria: all kind of clinical studies methodology that reported interventions with connective tissue graft using the modified coronally advanced flap, with at least 6-months evaluation in patients with Miller’s class I or II recessions. Exclusion criteria: pre-clinical studies, studies with isolated gingival recession and exclusive studies of Miller’s class III and IV. Results: 4 articles were selected (2 case series, 1 controlled clinical study and 1 controlled randomized clinical trial). Conclusions: Modified coronally advanced flap in combination with a connective tissue graft is associated with a greater recession reduction, greater increase in buccal keratinized tissue height and higher probability of complete root coverage in a long-term evaluation (5 years). This modality of root coverage surgery has been demonstrated to be a safe and predictable approach for multiple recession-type defects in patients with aesthetic demands. High aesthetic results are achieved in both views according to the point of view of both clinicians and patients.

Full textObjective: Perform a histomorphometric analysis of the connective tissue removed from the palate using the Harris technique (double blade). Materials and methods: 14 patients between men and women, 25 to 50 years of age, with Miller class I and II gingival recessions underwent root covering surgery. The connective tissue sample was collected from the region between the distal upper 1st molar and the distal upper canine, being obtained according to the technique evaluated in the study. An excess size of connective tissue was removed in the surgery used in the research. Unused epithelial tissue and connective tissue were stored in eppendorf with 10% formaldehyde for histomorphometric analysis. In total, 11 samples were evaluated. All morphological analyzes were performed by two independent and blindly calibrated evaluators, the data being compiled and evaluated statistically by a third independent evaluator. Results: We observed that six samples did not present remnants of epithelial tissue, five had remnants of epithelial tissue on a fraction of the surface of the connective tissue, and two had remnants of epithelial tissue along almost the entire length of the connective tissue. Conclusion: There is not always complete elimination of epithelial tissue after subepithelial connective tissue graft removal using the Harris technique using a double-blade scalpel.

Full textThe technique of subepithelial connective tissue grafting has become widely used by implantology due to the excellent results obtained in an attempt to improve aesthetic and functional aspects. The objective of this work was to perform a literature review, and to show the possible techniques of treatment, results and prognostics of connective tissue grafts in implanted areas, where the gingiva required a new marginal contour. At the conclusion of the literature review, it was possible to conclude that there are several connective tissue grafting techniques, each one of which makes it possible to achieve predictable and satisfactory results in the rehabilitation of the peri-implant gingival contour.

Full textAim: In patients with gingival recession (GR) and non-carious cervical lesion (NCCL), in terms of recession reduction, root coverage, dentin sensitivity and aesthetic: 1) Does the combined restorative/surgical approach is more effective than the surgical approach alone? 2) In patients treated with the combined approach, what are the impacts of different restorative materials? Materials and methods: Randomized clinical trials were searched in two databases. 12 publications were included. 471 patients with a Miller class I or II gingival recession were selected, with follow-up periods up to 24 months. Results: The mean GR reduction and the mean root coverage of the selected studies are respectively about 2,2 mm (± 0,69) and 89,7% (± 18,36) with the surgical procedure, and 2,1 mm (± 0,64) and 86,1% (± 18,34) with the combined procedure. Besides, both procedures presented a significant dentin hypersensitivity reduction and an aesthetic improvement. Nonetheless, with a restoration, the sensitivity scores were close to zero. Regarding the aesthetic, compared to resin modified glass ionomer, the resin composite showed a better color stability after one year. Conclusions: Both combined and surgical approaches seem to be as effective to achieve root coverage. Both techniques may reduce dentin hypersensitivity, but at restored sites, this reduction is maximal. Both procedures seem to induce an aesthetic improvement, although, when a restoration is performed, composite resins tend to provide slightly more aesthetic results. While ionomer resin restorations appear to be very well tolerated by the periodontal environment.

Full textIntrodution: Over the last decade the demand for an aesthetic smile (includes harmony and continuity of form) has become a significant concern in dentistry and particularly in Periodontal treatments. Gingival recessions with consequent root exposure and morphological changes of periodontal tissues, can be an important aesthetic problem and might be associated with other problems. Objective: The aim of this study was to compare which technique (CAF, CAF with CTG and TUN) becomes more advantageous, knowing that both are highly reliable techniques. Materials and methods: In this literature review, was made a research between June and September 2016, in Portuguese and English, without time limit, using the electronic databases: PubMed, Google Scholar using the following keywords: “tunnel technique”, “microsurgery”, “recession coverage”, “connective tissue graft”, “coronally advanced flap”, “coronally advanced flap vs. tunnel technique”. Were used 40 articles and two literary works (Clinical Periodontology and Implant Dentistry and Plastic-Esthetic Periodontal and Implant Surgery) that complement the subject. Conclusion: According to published literature procedures the most effective are those which use tissue grafts to the increase of gingival thickness. Since comparing the two techniques TUN and RRC, the first has an advantage over the second one, because it requires less incisions and has the preservation of the papillae which will bring positive aspects when healing.

Full textIntroduction: Connective tissue grafts are frequently used in root coverage procedures. Some suggest a single incision technique, promoting primary intention healing at the donor site, probably inducing less postoperative morbidity to the patient. Others propose the free gingival graft, having a better view of the surgical site and advantages in gingival thickness. Aim: To compare the healing pattern in the palate following harvesting of connective tissue graft at 3 and 6 months of postoperative by two different harvesting techniques. Materials and Methods: This is a prospective cohort study, over a period of 6 months. Three evaluation times were made - surgery day (T0), 3 months (T1) and 6 months after surgery (T2). The sample included 19 lateral palatal donor sites. Four subepithelial tissue grafts were harvested using the single incision technique by Hürzeler MB. & Weng D. while the remaining 15 de-epithelialized tissue grafts were harvested using the technique by Zucchelli, G. et al. Digital evaluation protocol: Patient’s casts were recorded at T0, T1 and T2. The casts were digitalized by an intra-oral scanner (DentalWings®). In the computer programs, Geomagic Control X® e Materialise Magics®, the three-dimensional digital analysis of the intervened areas was recorded. Results: Regarding to the SE technique mean thickness and volume change was calculated, getting 0.36mm and 77.52mm3, respectively, at T1, and, 0.10mm and 16.99mm3, respectively, at T2. Regarding to the DE group mean thickness and volume change was calculated, getting -0.26mm and 46.99mm3, respectively, at T1, and, -0.25mm and 50.53mm3, respectively, at T2. Conclusions: ETC harvesting promotes hard palate soft tissues changes and volume/thickness gain or loss may occur; tissue stabilization appears not to happen in the first 3 months, with subsequent changes in place. There appears to be a non-significant tendency for the DE technique to produce minor soft tissue changes comparing to the SE technique. The three-dimensional digital evaluation has shown to be innovative, allowing us to study soft tissue healing dynamics.

Directly attached to this success is the final shape of the gingival contour combined with SCTG, which contributes to the increase and maintenance of the alveolar ridge, reduces post-extraction defects, allows installation of immediate implants as well as the treatment of recession, fenestration and peri-implant disease. This work aimed to present a bibliographical review, considering general aspects such as anatomy and periodontal morphology, indications and surgical techniques related to the use of SCTG in peri-implant plastic surgery. A bibliographical research was carried out, showing its several advantages and providing to the area professionals a general and contemporary view of the subject. It is clear from the studies described that the SCTG associated to the various surgical techniques of tissue manipulation should be the treatment of choice to achieve an adequate keratinized tissue in the region of esthetic implants and to obtain aesthetic and functional success in oral rehabilitation.

Full textGingival retraction is the displacement of the gingival margin with reference to the amelo-cementitious junction, causing exposure of the cementum and root of the tooth. This process leads to loss of protective and sustaining tissues which can cause irreversible damage. The consequences range from the aesthetic commitment of the gingiva to tooth loss, by disintegration, elimination of the periodontal fibers and the bone that supports the tooth. The literature demonstrates a range of procedures aimed at correcting the defects of gingival retraction through surgeries where it will be necessary to remove tissue from one site so that it can be grafted in another. This review aims to demonstrate the advantages of the use of subepithelial connective tissue in the resolution of these problems as well as to expose the techniques that may be associated with the subepithelial connective graft.

Full textIntroduction: The treatment of single, maxillary and mandibular, gingival recessions (GR), can be done using several techniques of periodontal plastic surgery (PPS), among them VISTA technique and the modified tunnel technique by Zuhr. The addition of a connective tissue graft (CTG) with different techniques of PPS allows root coverage and gingival thickening and provides long-term stability to the gingival margin. Aim: To prospectively evaluate: mean gingival thickening and the root coverage, at 3 and 6 months of postoperative; the immediate postoperative period experienced by operated patients; as well the aesthetic result obtained after 6 months of healing. Materials and Methods: This study is a prospective cohort study, over a period of 6 months. Three evaluation times were made - surgery day (T0), 3 months (T1) and 6 months after surgery (T2) Sample: 5 patients with 6 Miller, single, maxillary and mandibular, GR. Three Miller Class I GR were treated with a CTG associated with the modified tunnel technique by Zuhr, O. et al. (2007), while the three Miller Class III GR were treated with a CTG associated with the VISTA technique described by Zadeh, H. (2011). Digital evaluation protocol: Patient’s casts were recorded at T0, T1 and T2. The casts were digitalized by an intra-oral scanner (DentalWings®), obtaining an STL file for each situation. In the computer program, Geomagic Control X®, the three-dimensional digital analysis of the intervened areas was recorded. Results: VISTA + CTG and modified tunnel + CTG technique, at 6 months of post-operative, allowed, respectively: a mean gain of gingival thickness of 1,35 mm and 0,81 mm; as well a % of root coverage of 81,28 % and 66,58 %. Conclusion: Within the limitations of this research, this two techniques of PPS allow to obtain: a considerable gingival thickening; as well a root coverage of gingival recessions with clinical success and with a good aesthetic result.

Full textAim This study set out to evaluate the clinical and aesthetic outcomes of connective tissue grafts (CTG) to platelet rich fibrin (PRF) in treating gingival recession. It was hypothesised that PRF could be as effective as CTGs in treating recession with improved aesthetic results. To the best of my knowledge this clinical study is unique in the South African setting in that an objective aesthetic scoring system was used to report on aesthetic changes and also this study was patient based to determine patient satisfaction with aesthetic outcomes. Methods and materials This six month study was an extended case series with a randomised split-mouth design. Six patients with a total of twenty two sites underwent treatment. However, only five patients fulfiled the study’s follow-up requirements. The patient who failed to comply with the follow-up appointments was disqualified from the study. Each site was paired with a similar lesion on the opposite or contralateral side and randomly assigned to the CTG (control) or PRF (test) treatment. Six variables were recorded over the study period. These variables were probing depth, recession depth, recession width, clinical attachment level, keratinised tissue width and gingival thickness. These were measured at the following intervals: 0, 8, 12, 16 and 24 weeks. Photographs were taken at baseline and at 24 weeks to evaluate aesthetics using the Pink Esthetic Score. At the end of the study period, patients were given a questionnaire to assess their satisfaction with treatment outcomes. Results and Conclusions Both treatments improved the clinical outcomes but CTGs demonstrated improvements at a greater number of sites than PRF (60% to 30% respectively). The aesthetic scores improved at four sites for both CTGs and PRF with only one site in each group scoring lower at the end of the study. The aesthetic scores at the remaining sites did not change over the study period. Therefore, both CTGs and PRF demonstrated the potential to improve or maintain aesthetic results. Analyses of the patient questionnaire showed that patients were satisfied with the aesthetic outcomes of both treatments. The results from this study indicate that both CTGs and PRF membranes can be effective in treating gingival recession and both treatments can improve clinical and aesthetic outcomes.
