Socket Preservation Technique Using Bovine Bone, Platelet Rich Fibrin Or A Combination Of Both: A Clinical, Radiographic And Histological Assesment At 4 Months

Not Applicable

Completed

• Conditions: Post Extraction Alveolar Bone Resorption; Ridge Preservation
• Interventions: Procedure: Socket preservation

• Registration Number: NCT05889377
• Lead Sponsor: Saint-Joseph University

Brief Summary

Post extraction alveolar bone resorption is one of the main challenges that face oral implantologists in their daily surgical practice (1). To palliate to post-extraction resorption, advanced bone grafting and regeneration techniques have been described (2). However, these procedures, although well documented and validated, still have relatively high complication rates and patient morbidity, in addition to the elevated cost and duration of treatment (3). Socket preservation is a very useful technique in order to counter post extraction resorption issues, therefore eliminating the need for future complicated and delicate regeneration procedures (4). Many biomaterials were proposed for socket preservation such as allografts and bovine hydroxyapatite (5). Recently autologous platelet concentrates such as Platelet Rich Fibrin PRF were described as a potential socket filler material (6).

In the proposed protocol, fresh extraction sockets will be either grafted by a bovine bone substitute, a PRF plug or a mixture of both. Sockets will then be clinically and radiographically monitored over time to assess three-dimensional soft and hard tissue stability. Bone quality will be histologically examined at 6 months implant placement. A no graft group will serve as control.

The results of this study may be of major importance since they could give an objective idea of the most efficient socket preservation technique, thus offering simple and secure oral rehabilitation solutions for both patient and practitioner.
