Uso da matriz colágena suína no recobrimento radicular

Abstract

Gingival recession is a condition that presents high prevalence in the world population. The mucogingival surgeries are indicated to increase the width of attached keratinized mucosa, alveolar ridges, to eliminate high muscular attachments, and to treat gingival recessions. The main surgical techniques for root coverage use two surgical areas (recipient and donor areas), increasing patient morbidity. The porcine collagen matrix (CM) is an alternative to autogenous donor tissue, which can act as a possible substitute. The purpose of this review was to analyze the efficiency of the porcine collagen matrix (CM) in the gingival recessions. For this, searches were made on the PubMed, Cochrane Database of Systematic Reviews and Dentistry and Oral Sciences Source electronic databases. On the evaluation of CM efficacy, seven double-blind, clinical randomized trials were selected. The results showed that the use of CM may be a satisfactory option as a substitute of autogenous donor tissue in root covering procedures. The gingival connective tissue graft remains the gold standard in the treatment of gingival recessions. The CM is presented as a substitute, especially in cases of low amounts of autogenous donor material and in cases where the risk of patient morbidity is high such in the multiple recession areas.
