Abstract
Purpose: There have been many positive clinical results of autogenous tooth bone graft materials (AutoBT) since it developed in 2008. The purpose of this study is to evaluate the prognosis of graft materials according to the condition of the donor tooth.
Materials and Methods: Ninety seven patients (187 implants) who treated implant installation with a variety of bone graft using AutoBT in Seoul national university Bundang hospital from 2009 to 2010. Total 191 extracted teeth were processed to graft materials. AutoBT was calssified into 4 groups according to donor tooth condition (fresh, caries, nonvital, periodontitis). AutoBT was used in guided bone regeneration, sinus graft, socket preservation, and ridge augmentation. The delayed or simultaneous implant installation was done. We measured primary and secondary stability. Postoperative complication and implant survival rate were evaluated. Organic component of AutoBT was analyzed.
Results: Most complications were wound dehiscence. There were no infections. Wound dehiscence showed favorable secondary healing. Good implant survival rate and secondary stability were obtained in all groups. Small amount of protein and type I collagen were detected in group 1 (fresh tooth) and group 2 (caries).
Conclusions: There were no complications related with bone material itself and donor tooth conditions didn’t affect the implant stability and survival rate.
