This retrospective research was performed to evaluate the marginal bone level changes around dental implants with various types of prosthetic restorations in the posterior regions of the maxillary bone that were placed by clinicians at an academic institution. Intraoral radiographs were used to evaluate the peri-implant bone level changes. The results demonstrated that there were significant differences between implants restored by platform-switching vs. platform-matching on the mesial and distal at the prosthetic restoration and the 1-year visits, and between implants in patients with diabetes vs. non-diabetes on the distal at the 1-year visit. This study complemented the present scarce literature on this topic through the identification of patient-related and implant-related characteristics that may contribute to peri-implant bone loss.
