Abstract(s)
Objetivo: Revisão da literatura científica referente aos resultados clínicos de procedimentos cirúrgicos para aumento da largura de tecido queratinizado peri-implantar.
Métodos: Realizada uma pesquisa com recurso à base de dados PubMed para execução desta revisão literatura. Foram aplicados critérios de inclusão, tais como estudos clínicos controlados aleatorizados, tempo de seguimento mínimo de 3 meses, procedimentos mucogengivais em implantes para aumento de tecido queratinizado e estudos em humanos.
Resultados: Analisados 5 artigos que comparavam diferentes materiais para o aumento de tecido queratinizado peri-implantar, tais como o enxerto de tecido conjuntivo, matriz de colagénio xenogénica, matriz dérmica acelular, matriz colagénio, enxerto de tecido conjuntivo subepitelial e fibrina rica em plaquetas preparada com titânio.
Conclusões: Nos estudos analisados conseguimos evidenciar uma tendência de superioridade do enxerto de tecido conjuntivo (ETC) para o aumento de tecido queratinizado peri-implantar, no entanto, alguns estudos não comprovaram diferenças estatisticamente significativas.
Objectives: Review of the scientific literature regarding the clinical results of surgical procedures to increase the width of peri-implant keratinized tissue. Methods: A search was carried out using the PubMed database to carry out the literature revision. Inclusion and exclusion criteria were applied, such as randomized controlled clinical studies, minimum follow-up time of 3 months, mucogingival procedures in implants for keratinized tissue augmentation and studies in humans. Results: Five articles were analyzed comparing different materials for peri-implant keratinized tissue augmentation, such as connective tissue graft, xenogeneic collagen matrix, acellular dermal matrix, collagen matrix, subepithelial connective tissue graft and platelet-rich fibrin prepared with titanium. Conclusions: In the analyzed studies, we were able to show a trend towards superiority of the connective tissue graft (ETC) for the increase of peri-implant keratinized tissue, however, some studies did not prove statistically significant differences.
