Crestal Bone Response to Narrow vs. Regular Tie-Base in Subcrestal Implants

NCT07196228 · Status: NOT_YET_RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 40

Summary

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.
