Autogenous tooth bone graft material prepared chairside and its clinical applications: a systematic review

This systematic review was conducted to evaluate the available literature on the clinical outcomes of the use of autogenous tooth bone graft prepared chairside, and its current applications. A literature search was done to answer the focused questions "In partially edentulous patients, what are the alveolar ridge volumetric changes, histological findings, and implant survival rates in sites augmented with autogenous tooth bone graft prepared chairside?" Twenty articles were included at the end of the database search. Reported alveolar bone dimension changes after ridge preservation ranged between - 0.64 mm and + 2.26 mm for height, and between - 1.21 mm and + 0.41 mm for width. Augmented sites showed a significant increase in their dimensions in all investigations. The implant survival rate was 98.8% for delayed placement and 97.4% for immediate placement. Additional reports were found on the percentage bone formation following the use of this graft at different postoperative time points, which showed a higher bone volume with time. Currently available studies have included small samples, with short follow-up periods, and most have lacked a control group. Within the limitations of this review, the available evidence suggests that the autogenous tooth bone graft prepared chairside is as effective as other bone grafting materials.
