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

• Status: Completed
• Trial end date: 2015-06-01
• Target enrollment: 0
• Participant gender: All

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).

• Phase: Phase 4
• Accepts Healthy Volunteers?: No
