Impact of Soft Tissue Grafts on Tissue Alterations After Immediate Tooth Replacement

Dental Implants Clinical Trial

Official title: Soft and Hard Tissue Stability After Immediate Tooth Replacement With Implant in Fresh Sockets Grafted With Different Soft Tissue Grafts

Status Completed

Clinical Trial Summary

This study evaluates the impact of soft tissue grafts on soft tissue recession following immediate implant, provisional and bone graft placement in compromised sockets. One third of the patients received a collagen matrix (CM group), another third received a connective tissue graft removed from the palate (CTG group) and the final third did not receive any soft tissue graft (CTL group).

Clinical Trial Description

Preventing soft tissue recession following flapless immediate implant and provisional placement (IIPP) in sockets with facial bone dehiscences is a challenge, mainly in esthetic areas. This study evaluated the impact of soft tissue grafts on peri-implant alterations after 1-year follow-up. Twenty-four patients with one single failing maxillary incisor presenting facial bone dehiscence and receiving IIPP were randomly divided in three groups (n= 8 in each group): Control (CTL); Collagen Matrix (CM); Connective tissue graft (CTG). In addition to soft tissue grafts, all groups were treated with collagen membrane and deproteinized bovine bone mineral containing 10% of porcine collagen. Clinical, photographic and tomographic analyses were performed at baseline, 6 and 12 months after surgery to evaluate tissue alterations. ;
