Utilização de matrizes dérmicas para aumento de gengiva aderente

Abstract

Introdução: Os enxertos gengivais, nomeadamente o enxerto gengival livre e o enxerto de tecido conjuntivo, apresentam resultados mais previsíveis e a sua utilização está fortemente indicada em aumentos de gengiva aderente. Contudo, recentemente, foram introduzidos outras técnicas de enxertos alternativos e biomateriais, de forma a evitar morbilidade da zona dadora e superar a disponibilidade limitada de tecido autógeno. Um dos procedimentos alternativos são as matrizes dérmicas acelulares. Objectivo: Este trabalho pretende, através da realização de uma revisão da literatura, verificar a aplicação das matrizes dérmicas xenógenas nas técnicas de cirurgia plástica periodontal para aumento de gengiva aderente. E além disso, outro dos objectivos deste trabalho é exemplificar o modo de utilização destas matrizes dérmicas em cirurgias periodontais para aumento de gengiva aderente, recorrendo a uma série de casos clínicos. Material e Métodos: Efectuou-se uma pesquisa recorrendo a uma base de dados primária (MEDLINE), selecionando-se publicações entre 2000 e Janeiro de 2016, publicações em língua inglesa e portuguesa, e publicações que descrevessem a utilização de matrizes dérmicas para aumento de gengiva aderente. Resultados: No total foram identificados 9 artigos: 3 revisões sistemáticas e 1 meta-análise, 2 estudos clínicos controlados e aleatorizados e 3 séries de casos. Conclusão: A utilização de matrizes dérmicas para aumento de gengiva aderente é um procedimento eficaz. Contudo, de acordo com a evidência disponível, não se verifica coerência nos ganhos significativos de tecido queratinizado com este material. Em investigações futuras são desejáveis estudos com um maior período de follow-up, de forma a que se possam retirar conclusões mais sólidas sobre os benefícios alongo prazo destes materiais para os pacientes. Introduction: Gingival grafts, namely free gingival grafts and connective tissue grafts, have more predictable results and their use is strongly recommended for agumentation of attached gingiva. Despite this, recently, other techniques were introduced in the form of alternative biomaterials and grafts to avoid the morbidity associated to the donor area and overcome the limited availability of autologous tissue. One these alternative procedures are acellular dermal matrix. Objective: This paper aims, by conducting a literature review, to examine the application of the xenogenic dermal matrix in periodontal plastic surgery techniques to increase attached gingiva. In addition, another objective of this study is to illustrate how to use these dermal matrixes in periodontal surgery to increase attached gingiva, using a series of clinical cases. Material and Methods: The search resorted to the primary data base MEDLINE (PubMed) selecting publications between 2000 and January 2016, publications in English and Portuguese, and publications that describe the use of dermal matrix to increase attached gengiva. Results: In total were identified nine articles: three systematic reviews and one meta-analysis, two randomized controlled clinical and and three case series. Conclusion: The use of acellular dermal matrix to increase the attached gengiva is an effective procedure. However, according to the available evidence, there is no coherence in the significative gains of the keratinized tissue with this material. In further investigations, will be necessary studies with a bigger follow-up time, to be possible to take more solid conclusions about the long-term benefits of these materials in the patients.
