Immediate molar implants with customized healing abutments in different socket classes

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study follows consecutive patients needing extraction and immediate implant placement in the posterior jaw. Each patient receives a flapless extraction, an implant placed immediately, grafting of the residual gap, and a chairside fabricated customized healing abutment to help shape the soft tissue. Participants are grouped by post-extraction socket class (A, B, or C) based on available bone for primary stability. The objective is to see how the customized healing abutment influences the preservation of peri-implant soft-tissue volume and emergence profile across socket types. Outcomes focus on soft-tissue contours and implant stability over the follow-up period.
