Comparing two types of healing abutments for dental implants

Comparison of Two Different Healing Abutments in Single Posterior Implants: A Randomized Clinical Trial

Not applicable Interventional Alexandria University · NCT06682559

This study tests whether a standard or a custom healing abutment helps the soft tissue around dental implants heal better after three months for adults needing single posterior implants.

What this trial studies

This clinical trial evaluates the effects of two different healing abutments on the soft tissue surrounding dental implants after three months. Participants will receive either a prefabricated healing abutment with a scan peg or a customized healing abutment, and the volumetric changes in peri-implant soft tissues will be analyzed. The study aims to determine which type of abutment promotes better healing and tissue volume. It involves adult patients requiring single posterior dental implants with specific eligibility criteria.

Who should consider this trial

Good fit: Ideal candidates are adult patients classified as ASA I or II who need single implants for missing mandibular posterior teeth.

Not a fit: Patients with uncontrolled systemic diseases, poor oral hygiene, or a history of head and neck radiation may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve healing outcomes and tissue volume for patients receiving dental implants.

How similar studies have performed: Previous studies have shown varying success with different types of healing abutments, but this specific comparison is novel.
