Alveolar Ridge Preservation Using Different Bone Substitutes

The Effect of Allograft, Toothgraft, Alloplast on Alveolar Ridge Preservation

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.

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.

3. exhibited Type I and II sockets

Exclusion Criteria:

1. nonsmokers.
2. Pregnant and breast-feeding females
3. patients with known contraindications to dental implant surgery (e.g., increased bleeding tendency, history of treatments such as radiotherapy,
