Abstract
Purpose: Autogenous bone harvesting offers biologic advantages for bone augmentation prior to implant placement. But the main limitation of intraoral bone grafts is the limited supply of autogenous bone. The most common treatment planning error is to overestimate the available bone for harvest from the mandible. The goal of this study was to give the clinical indices by quantify the amount of bone graft material present in the mandibular ramus area from various surgical cases.
Materials and Methods: This study reviewed operation records of 49 patients treated implant surgery with ramus bone harvesting in LivingWell Dental Hospital. Totally 62 ramus bone harvesting were performed in these patients using the trephine bur in the mandibular ramus area.
Results: The average quantities of the graft material obtained from the ramus area were 0.3cc (min. 0.1cc ~ max. 0.7cc) ; the average bone density was 1.95 g/ml ± 0.52 (min. 0.86 g/ml ~ max. 4.00 g/ml).
Conclusion: The results of the present study show the amounts of bone which can be harvested from mandibular ramus area in ordinary implant surgery.
