Current State of Clinical Trials Regarding Alveolar Bone Grafting

Abstract

Objectives

Alveolar ridge defects develop because of surgery, trauma, infection, or congenital malformations. Alveolar ridge defects can be resolved using an osseous replacement. The primary outcomes of osseous replacement are the maintenance of contour; the elimination of dead space, the reduction of postoperative infection; and the increase in bony and soft tissue healing. Recent research shows promising developments in dental bone grafts. This review presents the results of several clinical trials and provides updates on current alveolar bone grafting.

Design

In May 2023, we searched Clinicaltrials.gov for interventional clinical trials related to alveolar bone grafting. A total of 66 clinical trials were included using Boolean Operators AND, OR, NOT we used the “advanced search” option with the search terms [Alveolar Bone Grafting] OR [Ridge Preservation] OR [Dental Bone Grafting] OR [Ridge Augmentation]. Reviewed publications are summarized.

Results

28 out of the 66 trials were successfully completed. None of the trials had offered an invitation to enroll, and only one was terminated. Autograft was the most prevalent kind of grafting, at 28 out of 66, more than twice as prevalent as allograft, which ranked second at 12 out of 66.

Conclusion

this study shows a lack of variety in location, low results provided, and low clinical trials regarding bone rejection. The focus of published trials was mainly on cleft palate rehabilitation using secondary alveolar bone grafting, and the usage of L-prf, rh-FGF-2, rhBMP2, and hyaluronic acid in association with alveolar bone grafting showed remarkable results concerning bone's osteoconduction, osteoinduction, and osteogenesis.
