Abstract
|
|
|
Purpose: This prospective study is aimed to evaluate the peri-implant gingival tissue stability following tooth extraction and immediate implant placement by the use of a collagen-coated xenograft (Bio-Oss Collagen, Geistlich, Switzerland) in the gap which occurred between the implant and the walls of the fresh extraction socket.
Materials and Methods: Fifteen patients without medically compromised factors were selected and immediated implant placement followed by tooth extraction on the maxillary anterior single tooth area. Also, bone graft was performed in the gap between implant surface and inner aspect of the alveolar crest by using a collagen-coated xenograft without labial flap elevation. In 15 patients, peri-implant gingival tissue changes were evaluated clinically and radiographically at presurgical examination (T0), immediately after implant placement and provisionalization (T1), 6 months (T2), and 1 year after implant surgery (T3).
Results: All the implants remained in function at 1 year after implant surgery and have no signs of inflammation. There were no significantly changes about the bone level, papilla level, gingival margin level.
Conclusions: Our study showed that favorable implant success rates and peri-implant tissue response on the maxillary anterior area could be achieved by immediate implant with insertion of a collagen-coated xenograft in the extraction site.
