Grandes reconstruções de tecido mole através da utilização de matriz de colágeno porcino: revisão de literatura e relato de caso

Abstract

The importance of a healthy and functional mucogingival complex to the bone stability underlying tooth or implants is evident because of the increased attention given to procedures for soft tissue gain in clinical practice. Specifically in case of implants, the thickness and keratinization of soft tissue have been associated with more healthy tissue, less bone resorption, and superior aesthetics. Autogenous grafts have been used to increase the band of keratinized tissue. This technique is associated with high morbidity of the patient. In order to avoid the morbidity of the patient was developed a new collagen matrix called Mucograft®. The aims of this study were to review the literature about the use of materials for soft tissue grafts; check the use of these materials in large bone reconstructions in maxilla and mandible and; present a clinical case using Mucograft® in large reconstructions. Based on the literature review we conclude that autogenous tissues are widely used in small tissue reconstructions, which is the gold stardard; the use of alternative materials is recent; the use of Mucograft® is well documented in the literature showing good results, both in the subepithelial connective tissue replacement as in epithelial tissue and, no articles were found about large tissue reconstructions in large bone reconstruction.
