ABSTRACT:The objective of this study was to compare the connective tissue graft with Mucograft® collagen matrix, used to increase the peri-implant soft tissue, regarding the keratinized mucosa and number of fibroblasts between the grafted areas and the areas not inherent to the grafts. 12 patients were treated with 2 implants, one with connective tissue and the other with collagen matrix. Measurements were obtained before grafts and at uncoverage (2-3 months), biopsies were performed for fibroblast counting. Was an increase in the width and thickness of the KM for both grafts tested, the width of the KM was significantly higher in the connective tissue(P<0.014) the thickness was similar for both. There was no statistically significant difference in the number of fibroblasts between the two types of grafts. Conclusion: Both grafts resulted in increased the width and thickness of KM while maintaining similar fibroblast counts forboth areas. The connective tissue exhibited a statistically significant superiority in increasing the width of the KM, being the better indication for areas with KM < 2mm.
