Background: The objective of this study was to assess the osseointegration around endosseous dental implants inserted in fresh extraction sockets using β-Tricalcium phosphate bone graft with and without subepithelial connective tissue graft.
Methods: Twenty patients were enrolled in this study and allocated randomly to control group (Ten fresh extraction sockets were implanted by immediate dental implants and grafted by ß-tricalcium phosphate) or test group (Ten fresh extraction sockets were implanted by immediate dental implants and grafted by ß- tricalcium phosphate with a subepithelial connective tissue graft). The clinical parameters were monitored at 6,9 and 12 months post-implantation while the radiographic evaluation was conducted immediately after implant insertion(baseline),6 and 12 months postoperative. The implant stability was monitored using periotest at baseline,6 and 12 months after implantation.
Results: All implants in both groups were well osseointegrated resulting in a 100% cumulative success rate after one year follow up. There were no significant differences between the studied groups regarding clinical and radiographically parameters throughout the study period. However, the patients in test groups displayed better assessments regarding pocket depth, periotest value, keratinized mucosa and marginal bone level than patients within the control group.
Conclusion: The using of subepithelial connective tissue graft as a membrane with β-Tricalcium phosphate bone graft could improve osseointegration around dental implants in fresh extraction sockets.
