Application of modified mucogingival surgery in the treatment of gingival recession / 口腔疾病防治

@#With the increasing demand for beauty, the treatment of gingival recession has become a common request among patients. Clinically, gingival recession is mainly treated by surgery. The common surgical methods include free gingival grafting, pedicled flap technology and double flap technology (subepithelial connective tissue transplantation combined with coronally advanced flaps). If patients with indications are selected, satisfactory surgical results will be obtained. However, there are still some shortcomings in the above mentioned methods, such as the root coverage effect not being satisfactory. In recent years, researchers have put forward some improved schemes to minimize the shortcomings of the above methods to treat different degrees of gingival recession. A gingival unit graft containing gingival papilla and free gingiva can improve the blood supply of the recipient area and improve the effect of root coverage. It can obtain better root coverage for slight retraction, widening of the angular gingiva and deepening of the vestibular sulcus, but there may be issues with inconsistent color and shape of the gingiva after surgery, as well as poor aesthetic effects. Modified coronally advanced flaps, flaps prepared by the technique of half-thickness, full-thickness and half-thickness, and modified coronally advanced envelope flap technology are designed with the most serious retraction teeth as the center in the case of multiple gingival retractions, both of which can improve the effect of root covering. Tunnel technology and modified tunnel technology, without severing the gingival papilla and tunneling the gingival flap to accommodate the graft, can effectively reduce tissue damage and promote wound healing. This paper reviews the literature and summarizes the outcome of the modified surgery techniques in the treatment of gingival recession. These treatment options for gingival recession are proposed with the aim of improving clinical work, and some suggestions for the treatment of gingival recession to achieve a stable root coverage effect are put forward. In the future, the development direction of mucogingival surgery is to reduce trauma and have a stable curative effect.

Recubrimiento radicular de recesiones gingivales con matriz dérmica acelular / Root coverage of gingival recession with acellular dermal matrix

La recesión gingival es considerada como una deformidad o condición mucogingival, la Academia Americana de Periodontología, define a la recesión gingival como el desplazamiento del margen del tejido blando apical a la unión cemento-esmalte con la exposición de la superficie radicular. El tratamiento de las recesiones gingivales es un motivo de consulta común debido a razones estéticas, hipersensibilidad dentinaria, molestias durante el cepillado e incluso temor a la pérdida dentaria. Es una situación clínica común, 60% de la población humana tiene algún tipo de recesión gingival. Al realizar el examen clínico a paciente masculino de 55 años, se observó una recesión gingival tipo 1 (RT1) sin pérdida de inserción interproximal de la clasificación de Cairo. Se realizó el colgajo posicionado coronalmente (CPC) utilizando una matriz dérmica acelular (MDA) de origen humano OrACELL®. Se obtuvo resultado favorable en el recubrimiento de recesiones gingivales múltiples; considerándolos como una buena alternativa frente a los injertos gingivales autógenos. Concluyendo que, el uso de la matriz dérmica acelular para el tratamiento de la recesión gingival tipo 1 es una adecuada opción para el recubrimiento radicular. Se recomiendan más estudios a largo plazo para ver la estabilidad de los resultados obtenidos con la MDA (AU)

Gingival recession, considered a deformity or mucogingival condition, the American Academy of Periodontology, defines gingival recession as the exposure of the root surface resulting from migration of the gingival margin apical to the cementoenamel junction (CEJ). The treatment of gingival recessions is a common reason for consultation due to aesthetic reasons, dentin hypersensitivity, discomfort during brushing and even fear of tooth loss. It is a common clinical situation, 60% of the human population has some kind of gingival recession. Clinical examination of a 55-year-old male patient showed a type 1 gingival recession (RT1) without loss of interproximal insertion of the Cairo classification. Coronally advanced flap (CAF) was performed using an acellular dermal matrix (ADM) of human origin OrACELL®. Favorable results were obtained in the coating of multiple gingival recessions; considering them as a good alternative to autogenous gingival grafts. Concluding that, the use of the acellular dermal matrix for the treatment of gingival recession type 1, is a suitable option for root lining. Further long-term studies are recommended to see the elasticity of MDA outcomes (AU)

Vestibular incision subperiosteal tunnel access (vista) con tejido conectivo versus mucograft ® en el tratamiento de recesiones clase III / Vestibular incision subperiosteal tunnel access (vista) with connective tissue graft versus mucograft ® in the treatment of class III recessions

RESUMEN: Este caso clínico de boca dividida tiene como objetivo comparar los resultados clínicos obtenidos a 6 meses mediante el uso de técnica VISTA, en combinación con injerto de tejido conectivo (ITC) versus Mucograft® en el tratamiento de recesiones gingivales III de Miller, con fenotipo gingival fino. El resultado muestra que ambos injertos logran mejorar el fenotipo gingival y un mayor porcentaje de cobertura radicular, sin embargo, el ITC provee mayor volumen gingival. No obstante, el Mucograft® proporciona mejores resultados estéticos y menor morbilidad.

ABSTRACT: The aim of this split mouth study, is to compare the results obtained in 6 month follow-up by using VISTA technique in combination with connective tissue graft (CTG) versus Mucograft® in the treatment of Miller´s III gingival recessions, with thin gingival phenotype. The results show that both grafts improve the gingival phenotype and provide higher root coverage percentage, however, CTG provides more gingival volume. Nevertheless, Mucograft® shows better aesthetic results and lower morbidity.

Research progress on substitutes for autogenous soft tissue grafts in mucogingival surgery / 华西口腔医学杂志

Mucogingival surgery is a general term for periodontal surgeries that correct aberrant periodontal soft tissues. Conventional mucogingival surgeries with pedicle flap or autologous soft tissue graft for treatment of gingival recession and insufficient keratinized tissues are always related to disadvantages such as need for a second surgery site, limited supplies, and complaints for postoperative discomfort. In this regard, research and application of soft tissue substitutes have gained increasing attention. Various kinds of soft tissue substitutes, including acellular dermal matrix and xenogeneic collagen matrix, have been developed and applied to clinical treatment. This review aims to summarize advances in research of the characteristics and clinical effectiveness of several soft tissue substitutes and provide references for clinical application.

Progress in clinical treatment and etiology of gingival recession / 口腔疾病防治

@#Gingival recession is one of the common oral symptoms. Periodontal soft tissue defects caused by gingival recession and problems related to aesthetics, prosthetics and orthodontic treatment have garnered increasing attention. This article reviews the etiology, classification and treatment of gingival recession to provide a reference for the diagnosis and treatment of gingival recession. Anatomical characteristics of teeth, bacterial and viral infection, Occlusion trauma, Improperbrushing methods and other daily behaviors and iatrogenic factors may lead to gingival recession. Miller classification is the most commonly used classification standard. It is divided into 4 degrees according to the relationship between gingival recession and the association between the gingival membrane and the loss of adjacent alveolar bone or interdental papilla. Gingival surgeries, such as coronally advanced flap, laterally positioned flap, subepithelial connective tissue graft for Miller Ⅰ degrees and Ⅱ gingival recession retreat, obtain a more satisfactory success rate. Regarding the Ⅲ degree gingival recession, the postoperative curative effect is poor and can only cover part of the root. Regarding Ⅳ degrees gingival recession, surgery cannot reach the root surface coverage. For patients with Miller Ⅳgingival recession caused by severe periodontitis, the surgical treatment is poor, and repair methods, such as sputum, can also be considered. In recent years, a variety of biological materials have been jointly applied to gingival surgery, such as tooth enamel matrix derivative (EMD), allograft acellular dermal matrix (ADM), porcine collagen matrix (PCM) and platelet-rich fibrin (PRF). The use of these biomaterials can improve root coverage, increase gingival thickness and keratinized gingival width, avoid the requirement of palatal flap removal, reduce the surgical risk and increase patient compliance.

Gingival recession and minimally invasive tunnel technique / 口腔疾病防治

@#Gingival recession (GR) is characterized by exposure of the root surface into oral environment due to apical migration of the marginal gingiva to the cementoenamel junction (CEJ). A high prevalence of GR has been reported in several representative population samples. GR may result in a certain degree of functional and aesthetic alterations if left untreated for long periods. In severe cases, root-dentin hypersensitivity, abrasion, abfraction and root caries may also be involved in GR, which increases the challenge of plaque control. The etiology of GR is multifactorial, including periodontal disease, local anatomical variation, tooth malposition, improper tooth brushing, mechanical trauma and iatrogenic factors, of which periodontal disease is the most common cause. The treatments of GR consist of nonsurgical and surgical therapy, and the latter generally involves mucogingival surgery to restore the aesthetics and function of the local gingival recession. However, over the past 50 years, the periodontal plastic surgical technique has evolved from the traditional free gingival graft method into a more advanced, minimally invasive tunnel technique. For this technique, sulcular incisions instead of vertical relieving incisions are provided through each recession area, and full thickness mucoperiosteal flaps are created and extended beyond the mucogingival junction to facilitate coronal displacement. Each pedicle adjacent to the recession is gently undermined to create a tunnel at recipient site, where either autograft or allograft can be used. A minimally invasive tunnel technique is a better method for root coverage and reduced postoperative patient discomfort. This technique is characterized by both practical and aesthetic features.

Vestibuloplastia peri-implantar associada à regeneração tecidual guiada no tratamento da peri-implantite / Peri-implant vestibuloplasty and guided tissue regeneration in the peri-implantitis treatment

Levando em consideração que a peri-implantite é de etiologia multifatorial, embora o fator determinante seja o biofilme dentário, é interessante buscar formas de minimizar as perdas ósseas ocorridas. Desta maneira, ainda que ressalvas possam ser feitas à possibilidade concreta de se obter uma regeneração tecidual guiada, pode-se entender como uma alternativa válida para buscar, pelo menos, estabilizar o processo de progressão desta perda. Concomitantemente a este procedimento, e tendo em vista a indicação de vestibuloplastia para melhor prevenção da recidiva de peri-implantite, foi possível obter um resultado favorável dentro do objetivo proposto, em uma única intervenção cirúrgica. Material e métodos: paciente do sexo feminino, com 68 anos de idade, fumante moderada (8-10 cigarros/dia), se apresentou com exsudato purulento na face mesiovestibular do implante 46. Debelada a fase aguda por meio de fisioterapia local, a paciente foi submetida à cirurgia peri-implantar visando à interceptação da perda óssea por meio de "regeneração tecidual guiada" associada à vestibuloplastia, com a utilização de enxerto gengival subepitelial. Resultados: foi possível obter estabilização da perda óssea, bem como diminuição na profundidade de sondagem, além da redução de exsudato no implante em discussão. Conclusão: além disso, a vestibuloplastia criou melhores condições anatômicas estruturais devido ao tecido ceratinizado obtido e, sobretudo, criou um favorável acesso à escovação em toda a extensão dos quatro implantes, antevendo- -se melhor possibilidade de preservação do resultado.

Taking into account that the peri-implantitis is of multifactorial etiology, although the determining factor is the dental biofilm, it is interesting to look for ways to minimize the bone losses that have occurred. Thus, although safeguards can be made to the concrete possibility of obtaining a guided tissue regeneration, it can be understood as a valid alternative to seek to at least stabilize the process of progression of this loss. Concomitantly to this procedure and in view of the indication of vestibuloplasty for better prevention of recurrence of peri-implantitis, it was possible in a single surgical intervention to obtain a favorable result within the proposed objective. Material and methods: a 68-year-old female patient, moderate smoker (8-10 cigarettes/day) presented with purulent exudate on the mesiobuccal surface of the implant in the region of the 46. After the acute phase, through local physiotherapy, the patient underwent to peri-implant surgery aiming the interception of bone loss by means of "guided tissue regeneration" associated with vestibuloplasty with the use of subepithelial gingival graft. Results: it was possible to obtain a stabilization of the bone loss, as well as a decrease in the depth of probing, besides the reduction of exudate in the implant under discussion. Conclusion: the vestibuloplasty created better anatomical structural conditions due to the keratinized tissue obtained, and above all, the favorable access to brushing throughout the four implants, predicting a better possibility of preservation of the result.

Membrana de fibrina versus injerto conectivo como tratamiento de recesión gingival / Fibrin membrane versus connective tissue graft as gingival recession treatment

RESUMEN: Este caso clínico de boca dividida a 6 meses tiene como objetivo comparar los resultados obtenidos con una membrana de fibrina rica en plaquetas y leucocitos (L-PRF) y un injerto de tejido conectivo (ITC) en el tratamiento de recesiones gingivales clase1 de Miller en un paciente con biotipo gingival grueso. El resultado muestra que el uso de una membrana de L-PRF provee un parcial cubrimiento de la recesión y un menor malestar subjetivo del paciente cuando se compara con el ITC. Sin embargo, el ITC proporciona un mayor porcentaje de cubrimiento radicular y un mejor resultado estético que la membrana de L-PRF al cabo de 6 meses.

ABSTRACT: The aim of this split-mouth clinical study, covering a 6 month period, is to compare the results obtained from Leucocyte and Platelet Rich Fibrin Membrane (L-PRF) and Connective Tissue Grafting (CTG) in the treatment of class 1 Miller gingival recessions in a patient with thick gingival biotype. The results show that the use of L-PRF membrane provides partial coverage of the recession, as well as lower subjective patient discomfort when compared with CTG. However, CTG provides a higher percentage of root coverage and better aesthetic results than the L-PRF membrane after a period of 6 months.

Técnica de enxerto gengival livre para aumento de tecido queratinizado em recessão gengival classe III de Miller / Free gingival graft technique for keratinized tissue increase in Miller III gingival recession ­ a case report

A presença ou ausência de gengiva inserida pode interferir na manutenção da saúde gengival, uma vez que sua deficiência leva à exposição radicular dificultando o processo de higienização, o que resulta na presença de biofilme e inflamação gengival com perda de inserção. Foi realizada terapia periodontal cirúrgica com enxerto gengival livre em paciente com recessão gengival classe III de Miller para aumento de faixa de tecido queratinizado. Após período de pós-operatório e acompanhamento de um ano e 12 meses, foi observado ganho e manutenção de volume e altura do tecido queratinizado enxertado, com saúde gengival e ganho de inserção. Nos casos onde há necessidade de reforçar áreas fragilizadas pela diminuição ou falta de gengiva inserida, a técnica de enxerto gengival livre apresenta boa previsibilidade e manutenção da faixa de tecido queratinizado, favorecendo o controle de biofilme e saúde gengival.

The presence or absence of attached gingiva may interfere with the maintenance of gingival health, since its defi ciency in some cases complicates the process of cleaning, resulting in the presence of biofilm and gingival inflammation with insertion loss. This case report describes a surgical technique based on free gingival graft in a patient with gingival recession Miller class III to increase keratinized tissue band. After the postoperative period of 12 months tissue improvement was observed, as well as, volume maintenance and height of keratinized grafted tissue along with gum health and insertion gain. In cases where there is need to strengthen weakened areas by reducing or lack of attached gingiva, the free gingival graft technique has good predictability and maintenance of keratinized tissue range, favoring the control of biofilm and gingival health.

Tratamento cirúrgico para recobrimento radicular em molar superior / Surgical treatment for root coverage in the upper molar tooth ­ a case report

A recessão gengival é uma condição muito comum atualmente, definida como o deslocamento da margem gengival apicalmente à junção cemento/esmalte, com consequente exposição da superfície radicular ao ambiente bucal. Apesar das recessões gengivais afetarem diversos grupos de dentes, poucos trabalhos tentam elucidar qual é o melhor protocolo de tratamento para as recessões gengivais presentes em molares. Visando um protocolo cirúrgico que proporcione uma satisfatória taxa de recobrimento radicular e um melhor resultado estético, o presente relato de caso teve como objetivo apresentar uma técnica cirúrgica alternativa para o tratamento de recessões gengivais em molares superiores. Para tal, um retalho dividido foi confeccionado por meio de incisões relaxantes e deslocado lateralmente, a partir da área doadora, para o elemento dental com a recessão. Após o deslocamento do retalho, o mesmo foi suturado em posição. Seis meses após o procedimento, o paciente estava satisfeito com o resultado final alcançado, demonstrando que esse protocolo pode ser uma alternativa de tratamento aos protocolos existentes para o tratamento de recessões gengivais.

Gingival recession is a condition defined as the apical positioning of the gingival margin in relation to the cemento-enamel junction, resulting in root exposure in the oral environment. Although gingival recession may affect many groups of teeth, there are few studies that attempt to clarify which is the best treatment protocol for gingival recessions localized in molars. In order to evaluate a surgical approach that lead to a satisfactory root coverage rate and a good esthetic outcome, the aim of this case report is to present an alternative surgical technique for the treatment of gingival recession in upper molar teeth. For this, a split-flap was made through vertical incisions and laterally positioned from the donor area to the affected tooth and sutured in position. Six months after the procedure, the patient was satisfied with the final result achieved, showing that this protocol may be an alternative to the existing treatments for the gingival recession.

A combined approach to non-carious cervical lesions associated with gingival recession

Non-carious cervical lesions (NCCLs) with gingival recession require specific consideration on both aspects of hard and soft tissue lesion. In the restorative aspect, careful finishing and polishing of the restorations prior to mucogingival surgery is the critical factor contributing to success. Regarding surgery, assessment of the configuration of the lesion and the choice of surgical technique are important factors. The precise diagnosis and the choice of the proper treatment procedure should be made on the basis of both restorative and surgical considerations to ensure the successful treatment of NCCLs.
