Abstract
Purpose: This study is to evaluate the efficacy of the autogenous tooth bone graft material, clinically and radiologically, as related to implant installation.
Methods: In oral and maxillofacial surgery department of Ajou University Hospital, guided bone regeneration (GBR), implant placement combined with GBR, sinus graft, implant placement combined with sinus graft, and defect filling were performed in 46 patients, using autogenous tooth bone. Among these, 66 implants were inserted with autogenous tooth bone. Implant stability quotient (ISQ) was measured by Osstell Mentor (Integration Diagnostics, Goteborg, Sweden) on 39 implants on the operation date and 4 months later, and on 21 implants 9months on the average at the final setting of restoration. Twenty-eight implants with GBR and sinus graft (GBR group: n=14, sinus graft group: n=14) were evaluated radiologically to measure the resorption of grafted autogenous tooth bone after loading.
Results: The average initial stabilization of the installed implants was 67 ISQ, and the average secondary stabilization at 4 months later was 76. The average bone loss of GBR group as measured 8.0 months after application of prosthesis loading was 0.29 mm and the average bone loss of the sinus graft group as measured 7.6 months after application of prosthesis loading was 0.66 mm, respectively. In the histological assessment, formation of the new bone and continuous trabecular bone pattern was identified around autogenous tooth bone.
Conclusion: Based on these results, we concluded that autogenous tooth bone is an excellent bone graft material that can substitute the autogenous bone.
