PURPOSE: This case series evaluated the peri-implant tissue response following extraction and immediate placement and restoration of an implant in conjunction with subepithelial connective tissue grafting (SCTG) and bone grafting in the esthetic zone. Implant success rates and the peri-implant tissue response were also reported. METHODS AND MATERIALS: Ten patients (four men, six women) with a mean age of 48 years (range, 35 to 70) underwent extraction and immediate tooth replacement with SCTG and were evaluated clinically and radiographically presurgically (T0), immediately after immediate tooth replacement and SCTG (T1), and at 3 months (T2), 6 months (T3), and 12 months (T4) after surgery. Data was analyzed using Friedman and Wilcoxon signed-ranks tests at the significance level of a = .05. RESULTS: At 1 year, all implants remained osseointegrated, with an overall mean marginal bone change of +0.10 mm and a mean facial gingival level change of -0.05 mm. Modified Plaque Index scores showed that patients were able to maintain a good level of hygiene throughout the study. Papilla Index scores indicated that at T4, more than 50% papilla fill was observed in 80% of all sites. CONCLUSIONS: The results of this case series suggest that, in addition to a favorable implant success rate and peri-implant tissue response, the facial gingival level around single immediately placed implants can also be maintained following connective tissue grafting when proper three-dimensional implant positioning is achieved and bone is grafted into the implant-socket gap.
