Background: The purposes of the present study were to compare implant stabilities of mandibular block bonegraft and bovine bone graft and to evaluate influencing factors for implant stability in mandibular block bone(MBB) graft. Methods: This retrospective study investigated 1224 cases and 389 patients treated by one surgeon in theDepartment of Oral and Maxillofacial Surgery of Pusan National University Dental Hospital (Yangsan, Korea) betweenJanuary 2010 and December 2014. Proportions that MBB graft cases constitute in all implant restoration cases andin all bone graft cases were measured. Implant stability quotient (ISQ) values were achieved by the same surgeonbefore loading. The average ISQ values of the experimental groups were compared. In addition, ISQ values ofinfluencing factors, such as age, sex, implant size, and implant placement site, were compared within the MBBgroup using OsstellTM Mentor (Osstell®, Goteborg, Sweden). Paired t test and ANOVA were conducted for statisticalanalysis with a significance level of 0.05. Results: Fifty-five percent of all implant restoration cases performed bone graft while MBB cases constituted 34% ofall implant restoration cases and 61% of all bone graft cases. Comparing ISQ values according to bone graftmaterials, the MBB group manifested sufficient implant stability by presenting comparable ISQ value to that of theexperimental group without bone graft. Among the reviewed factors, females, mandibular molar regions, andimplants in larger diameter displayed greater implant stabilities. Conclusions: Satisfactory implant stability was accomplished upon administration of MBB graft. Within the limitationof this study, gender, implant site, and implant diameter were speculated to influence on implant stability in MBB graft.
