Abstract
Purpose: A method using autogenous tooth bone graft material that was made by his extracted tooth with appropriated process was developed and has been applied to the clinical cases. Also the tooth bone graft was reported excellent clinical effects and results. The aim of this study is to analyze the clinical application cases of Autogenous tooth block bone grafting material and to approve of effectiveness of its clinical outcomes.
Materials and Methods: 34 patients (24 males, 10 females) who visited Seoul National University Bundang Hospital had made Autogenous tooth block bone for graft procedure due to the insufficient residual bone volume and height for an implantation. The stability of an implant was measured by ISQ (Implant Stability Quotient) with an Osstell Mentor. The postoperative complications were analyzed during healing period. The significance of ISQ changes was statistically evaluated by a paired-t test.
Results: Twenty four patients had been grafted with autogenous tooth block bone and had installed 49 dental implants in Seoul National University Bundang Hospital. The mean follow up period was 30.82±14.17 months. The mean initial stability of overall implants was measured as 60.86±13.81 ISQ and second stability 75.02±9.44 ISQ. It showed statistically significant difference (P＜0.001). There were no remarkable complications or side effects during the all procedures.
Conclusions: Within the limitation of our study, it is suggested that the clinical outcomes of autogenous tooth block bone is outstanding with the stability of the implant in the grafted sites.
