Brief summary

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.

Detailed description

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.

Design outcomes

Primary

MeasureTime frameDescription
Clinical assessment3 monthsMeasure 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.

Secondary

MeasureTime frameDescription
Radiographic assessment3 monthsMeasuring 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,

Other

MeasureTime frameDescription
Histological3 monthsMasson trichrome special stain was used to detect the area percentage of immature collagen and mature collagen at magnification 20X. The immature collagen appeared blue in color while areas with mature collagen appeared reddish in color
Histomorphometric analysis3 monthsPhotomicrographs of 3 microscopic fields of each MT stained section, were captured at the original magnification of 20X using a digital camera(Canon EOS 650D) mounted on a light microscope(BX60,Olympus , Japan). The images were analyzed for obtaining the area percentage of mature and immature collagen of the newly formed bone using image J (1.41aNIH, USA)software
