Study Summary

The aim of this study was to evaluate the effects of definitive abutment connection at the time of implant placement on peri-implant bone levels and soft tissue changes in posterior maxilla and mandible regions.

Primary Outcome

Standardized digital periapical radiographs were taken at baseline (implant placement) and at the 1-year follow-up using the long-cone paralleling technique with a custom jig. Peri-implant marginal bone levels were measured on both the mesial and distal aspects to assess bone loss. Changes in peri-implant marginal bone levels were calculated by comparing the measurements at the 1-year follow-up to the baseline values.
