Marginal Bone Loss around Implants with Internal Hexagonal and Internal Conical Connections: A 12-Month Randomized Pilot Study.

ABSTRACT: The aim of this study was to analyze the differences in terms of the marginal bone level (MBL) around implants with either an internal conical or an internal hexagonal implant-prosthesis connection. A randomized clinical trial included patients in need of a single implant-supported restoration. The implant-prosthesis connection was either internal conical or internal hexagonal while maintaining the same type of implant macro- and microarchitecture. Clinical and radiographical variables were registered up to 12 months of follow-up, including MBL. A total of 30 patients were included in the study. The main outcome variable, MBL 12 months after prosthesis delivery, was statistically different in both groups: -0.25 (0.12) vs. -0.70 (0.43) (conical vs. hexagonal; p = 0.033). Differences were al
