Immediate implant placement for posterior teeth using a sealing socket abutment.

Immediate Implant Placement in the Posterior Region Combining Sealing Socket Abutment and Peri-implant Socket Filling.A Randomized Controlled Clinical Trial

NA · University of Liege · NCT05741749

This study is testing if a new type of dental implant cover can help keep the shape of the gums and jawbone better after placing implants in the back teeth for patients who need molars removed.

What this trial studies

This study aims to evaluate the effectiveness of a sealing socket abutment (SSA) in preserving soft tissue contour and alveolar ridge profile after immediate dental implant placement in the posterior region. It compares the outcomes of using SSA versus a standard healing abutment, focusing on soft tissue changes, hard tissue remodeling, and overall esthetic results. Patients with hopeless maxillary or mandibular molars will be recruited, and various health parameters will be assessed to ensure eligibility. The study will also measure patient-related outcomes to gauge satisfaction with the procedure.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old in good general health with specific dental conditions allowing for immediate implant placement.

Not a fit: Patients with autoimmune diseases, uncontrolled diabetes, or those requiring specific medical treatments prior to the procedure may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved aesthetic outcomes and better preservation of the alveolar ridge after dental implant procedures.

How similar studies have performed: While similar approaches have been explored, this specific combination of techniques is relatively novel and has not been extensively tested.
