Background and Aim: Bone loss surrounding dental implant is an unavoidable phenomenon that occasionally leads to implant failure. Implant-related bone loss exhibits different patterns and rate as per oral milieu and hygiene habits. This study was aimed to clinically assess the crestal bone losses in the postoperative phase of single implant placed in mandibular first molar regions. Materials and Methods: The present in vivo study was planned and completed on the patients selected from the Department of Prosthodontics of the institute. A total of twenty patients were selected randomly in which right mandibular first molar was rehabilitated by dental implants. All radiographic analysis was attempted by cone-beam computed tomography (CBCT). All twenty implants were placed by standard clinical protocols. CBCT analysis was attempted to measure existing bone levels on all four surfaces of implant. These measurements were completed at three different postoperative phases. Informed consent was obtained from all participating patients. Statistical Analysis and Results: Statistical analysis was completed by statistical software Statistical Package for the Social Sciences. P <0.05 was taken as statistically significant. Among all 20 patients, males were 14 and females were 6 in the age range of 25–45 years. Mean bone losses were in the range of 0.226–0.737 for Group I. Intergroup comparison by two-sample t-test showed a significant difference (0.01) for mesial surfaces. All mean values were maximum for mesial surfaces and minimum for lingual surfaces. Conclusion: The mean crestal bone loss at four implant surfaces evaluated at different postoperative phases was nonsignificant. However, there were significant differences in mean crestal bone loss at four surfaces of all studied implants in a particular group.
