This randomized controlled clinical trial included thirty patients. ARP was performed using either Allograft (Allograft group n=10), Tooth graft (Toothgraft group n=10), and beta tri-calcium- phosphate (beta tri-calcium group n=10). Changes in alveolar ridge dimensions were evaluated clinically and radiographically using cone beam computed tomography at baseline and 3 months. Core bone biopsy samples were obtained 3 months post-extraction during implant placement for histomorphometric analysis.
The primary objective of this study was to compare the efficacy of using allograft, autogenous tooth graft, and beta-tricalcium phosphate for alveolar ridge preservation (ARP) by examining the alveolar ridge height and width at baseline and 3 months after the ARP both clinically and radiographically. The secondary objective was to evaluate the quality of the newly formed bone using histomorphometric analysis.
