Aim: Radiographic and Histomorphometric assessment of Autogenous and Anorganic bovine bone graft mixture(Auto/ABB) vs Anorganic Bovine Bone(ABB) vs Absorbable gelatin sponge in alveolar socket preservation. Methodology: 30 patients, 1/group required extraction of mandibular molar tooth. Immediate and 6mnth post grafting CBCT radiographs. Crestal flaps, followed by core biopsy. Histomorphometric analysis of mean bone/area and residual percent and radiographical evaluation of bone loss. Results: Auto/ABB loss buccally 2.64±1.48 mm, lingually 1.59±0.86 mm, width 1.63±0.97mm. Mean bone area percent 42.34% residual material percent 32.19%. The ABB loss buccally 1.62mm, lingually 0.48mm and width 1.55mm. Bone area percent was 48.42% and residual percent of 20.87%. The AGS recorded a buccal loss of 1.29mm, lingual 1.44mm and horizontal 0.89mm. The Bone area percent 58.88% and a residual of 20.36%Conclusion: The Auto/ABB loss was highest in all the radiographical dimensions with the least bone area percent and the highest residual material present giving rise to questioning its effectiveness in socket preservation. ABB had the significant least amount of lingual loss of bone. The AGS showed promising results with the bone area percent recorded the most and the least residual material percent
