The aim of the study was to evaluate clinically and radiographically the volume changes of alveolar grafting using CAD/CAM xenogenic bone graft. Thorough pre-operative assessment of the patients carried out include history taking, physical examination and radiographic examination. The pre-operative volume and bone width of the defective alveolar ridge were measured on Computed Tomographic Cone Beam scans (CBCT). At the end of the follow-up period, no signs of infection or evidence of bone resorption were found. The radiographs showed newly formed bone and increase in alveolar bone volume and width in all cases. All augmented alveolar ridges showed good maturation of bone graft on the follow-up CBCT scans with evidence of normal bony architecture. No evidence of fibroses or scarring was noted in the bone graft. Post-operatively alveolar ridge post-operative volume ranged from 1109.9{u2013} 2997.4mm3 with mean volume of 2122.0 ± 649.4mm3. There was increase in bone volume by 40.0 % postoperatively compared to preoperative alveolar ridge volume. Paired sample t-test showed a statistically significant increase of bone volume, post-operatively (p<0.05)
