However, it is technique-sensitive, and requires strict case selection criteria. Tooth extraction triggers the biologic phenomenon of bone resorption, which is not prevented with immediate implant placement. This study aimed to evaluate the influence of deproteinized bovine bone mineral (DBBM) use on vertical bone loss around immediately placed mandibular molar implants. Materials and Methods: In this non-randomized clinical study, 14 patients with immediate molar implants in the lower jaw, restored with screw-retained single crowns were evaluated. The case group (with bone material use) received DBBM in conjunction with implant placement, while no grafting was performed in the control group. The vertical bone level changes were radiographically measured at the mesial and distal implant sides as the distance between the implant shoulder and first implant-bone contact in apical direction. Measurements were made at two time points of six months postoperatively and one year post-functional loading. The acquired data were statistically analyzed using two-way ANOVA. Results: The mean values for vertical bone loss at the mesial and distal reference points were greater in the control group (without bone replacement material use) than in the case group both six months postoperatively and one year post-functional loading. The difference was statistically significant at both time points (P<0.05). Conclusion: Within the limitation of this study, it can be concluded that the use of DBBM in immediate implants can reduce vertical bone loss. }, URL = {http://jrdms.dentaliau.ac.ir/article-1-379-en.html}, eprint = {http://jrdms.dentaliau.ac.ir/article-1-379-en.pdf}, journal = {Journal of Research in Dental and Maxillofacial Sciences}, doi = {10.52547/jrdms.7.3.148}, year = {2022} }
