An interventional study of Socket preservation by deproteinized bovine bone graft and socket preservation by deproteinized bovine bone graft mixed with advanced PRF+ in Alveolar Bone Loss, sponsored by Mansoura University. Completed at 1 site in Egypt. Open to participants aged 18 Years to 50 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-10-09.
Sponsored by Mansoura University · Not applicable, Interventional, and Treatment
Twenty patients were selected from the outpatient clinic of the Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Mansoura University seeking for extraction of non-restorable maxillary premolar teeth prior to delayed implant placement. Patients will be divided into 2 groups:
Group B: 10 implants were inserted after four months after socket preservation by putting two collagen sponge and in between deproteinized bovine bone with addition of advanced PRF plus layer.
304 studies on the registry are indexed under Alveolar Bone Loss; 77 are open to participants now.
This study's enrollment of 20 is below the median of 25 across 261 interventional studies indexed under Alveolar Bone Loss.

Exclusion Criteria:
Deproteinized bovine bone with collagen sponge was used for socket preservation for 10 cases and implant placement was performed after four months.
Procedure: Socket preservation by deproteinized bovine bone graft
Deproteinized bovine bone with advanced PRF+ and collagen sponge was used for socket preservation for 10 cases then implant placement was performed after four months.
Procedure: socket preservation by deproteinized bovine bone graft mixed with advanced PRF+
After atraumatic extraction, socket preservation by deproteinized bovine bone and collagen sponge was done and implant placement was performed after four months from that.

Implant stability
Implant stability measured using Resonance Frequency Analysis (RFA) with the Osstell Mentor device and SmartPeg. Measurements were recorded in four directions (every 90 degrees) and averaged per implant to provide an ISQ score (scale: 1 to 100, where higher scores indicate greater stability).
Time frame: 6 months

Ran from Nov 2025 to primary completion in Apr 2026, 5 months.
Of 160 non-industry interventional studies with no phase under Alveolar Bone Loss, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 30. This study's 5 months is below that.
Counting every sponsor, half of 160 studies reached it within 18 months; a quarter within 11 and three quarters within 30.
