About this trial

This 24-month randomized clinical trial evaluates peri-implant marginal bone changes at subcrestal implants restored with narrow versus regular tie-base abutments.

The study investigates whether narrow or regular tie-base abutments influence peri-implant crestal bone remodeling over 24 months.

This trial assesses the effect of abutment diameter (narrow vs. regular tie-base) on marginal bone stability at subcrestal implants after 24 months.

We aimed to determine if abutment diameter impacts peri-implant marginal bone levels by comparing narrow and regular tie-base abutments in a 24-month RCT.

Trial outcomes

Primary outcomes

Crestal bone level changes around subcrestal implants

Radiographic assessment of peri-implant marginal bone level changes (in millimeters) comparing narrow versus regular tie-base abutments. Measurements are taken from standardized periapical radiographs at the mesial and distal aspects of each implant, using the implant shoulder as reference.
