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.

Clinical assessment
Measure bone height loss in millimeter at baseline and after 3 months was measured using periodontal probe from the stent margin to the alveolar ridge crest at six points. In addition, Bone width loss was calculated by measuring alveolar ridge width buccopalatally in millimeter using a caliper clamp. The measurement was done perpendicular to the tangent of the dental arch at the mid-point of the extraction site approximately 4mm apical to the level of the marginal gingiva of the adjacent teeth.
Time frame: 3 months

Radiographic assessment
Measuring loss in bone height in millimeters between baseline and after 3 months. Loss in bone height was calculated by measuring the distance from the alveolar crest both buccally and palatally to a fixed anatomical landmark. In addition,
