Comparing different implant abutment connections for dental prostheses
Comparison of Abutments Engagement Configurations in Implant Supported Fixed Partial Dentures: a Randomized Clinical Trial
This study is testing which type of dental implant connection works better for people getting fixed prostheses to replace missing teeth, focusing on how well they heal and how satisfied patients are.

What this trial studies
This clinical trial compares various configurations of implant abutment connections in screw-retained fixed dental prostheses to assess their clinical and radiographic outcomes. It involves a randomized controlled design with patients receiving two internal connection dental implants to replace three missing posterior teeth in the mandible. Participants will be divided into two groups, one receiving engaging abutments and the other non-engaging abutments, with outcomes measured over time for bone levels, complications, and patient satisfaction. The study aims to identify which configuration results in fewer complications.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18 and older with three missing teeth in the posterior mandible who are suitable for implant-supported fixed dental prostheses.
Not a fit: Patients with less than three missing teeth, extensive bone grafting needs, or systemic diseases affecting bone healing may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved outcomes and reduced complications for patients receiving dental implants.
How similar studies have performed: Previous studies have shown varying success with different implant abutment configurations, making this approach both relevant and potentially beneficial.
