Biotivity A/C Plus Membrane for Alveolar Ridge Preservation after Tooth Extraction

Official title: Prospective, Assessment of Alveolar Ridge Preservation Using Biotivity™ Amnion Chorion Membranein Atraumatic Extraction Socket

Run by University of Maryland, Baltimore · NCT07091448 · Data updated 2026-11-12

This study tests whether a human amnion chorion membrane helps healing and bone preservation better than a collagen membrane after extracting a back tooth and preparing the site for an implant.

Is this trial a fit for you?

Likely a good fit

Adults 18 and older needing extraction and dental implant placement for a posterior tooth (premolar or molar, not third molars) with a suitable extraction socket as identified by CBCT.

Probably not a fit

Patients with insufficient space, active dental disease, uncontrolled periodontal disease, or other exclusion criteria may not benefit.

What this trial studies

This is a randomized, controlled pilot trial comparing Biotivity A/C Plus Membrane to a conventional collagen membrane for alveolar ridge preservation after atraumatic extraction of a posterior tooth. Participants receive bone graft material and membranes, followed by implant placement after about five months. Primary outcome focuses on soft tissue wound healing; secondary outcomes include changes in hard and soft tissue dimensions, histology of new bone, and implant placement feasibility. The study runs over approximately six months with nine visits, including screening, ARP surgery, post-operative follow-ups, and implant re-entry. Conducted at the University of Maryland School of Dentistry, it aims to determine if the amnion chorion membrane provides superior outcomes compared with standard care.

Why it matters

Potential benefit: If successful, participants may experience improved soft tissue healing and better preservation of bone around the implant site.

How similar studies have gone: Previous studies in similar ARP approaches with bioactive membranes have shown promise, but this exact amnion chorion membrane strategy is exploratory in this context.

Who can join: the full rules

Inclusion criteria:

1. Provision of informed consent
2. At least 18 years old
3. In need of one posterior tooth (premolar or molar), excluding third molars, planned for extraction and replacement with a dental implant
4. Type I or II extraction socket/ ridge identified at the time of enrolment with cone-beam CT scan

3. Active caries
4. Uncontrolled periodontal disease present
5. Evidence of active periapical, radicular, or endodontic lesions on teeth adjacent to study site
