- Primary Outcome Measures
Name Time Method Radiographic measurements of marginal bone loss were conducted via panoramic xray. The vertical distance between a reference point (implant-abutment interface) and the corresponding bone-to-implant contact point was measured (radiographic bone loss). The bone loss in millimeters detected radiographically was divided by the magnification factor to calculate actual bone loss. Bone level changes were calculated both medially and distally, based on the baseline and 3-year follow-up measurements. The deepest measurements of each implant at each time-point were calculated and recorded as proximal bone defect.
- Secondary Outcome Measures
Name Time Method Peri-implant probing depth (PD) was determined at four sides of each implant, buccally, palatally, mesially, and distally. The deepest PD at the 3- year follow-up was recorded.
