Augmentation of deficient alveolar ridges is a common procedure in oral and maxillofacial surgery. The choice between autogenous and allogenic bone blocks remains a critical decision point, with implications for patient outcomes. Materials and Methods: A prospective study was conducted to compare patient-centered outcome measures following augmentation with autogenous and allogenic bone blocks. Patients with deficient alveolar ridges requiring augmentation were randomly assigned to receive either autogenous or allogenic bone blocks. Clinical assessments and patient-reported outcomes were evaluated preoperatively and postoperatively at regular intervals. Outcome measures included bone volume gain, complication rates, patient satisfaction, and oral function. Results: Among the patients who received autogenous bone blocks, there was a mean bone volume gain of 3.2 mm (SD ± 0.5), while those who received allogenic bone blocks showed a mean gain of 2.8 mm (SD ± 0.4). Complication rates were similar in both groups, with 5% experiencing minor complications in the autogenous group and 6% in the allogenic group. Patient satisfaction scores were high in both groups, with 92% of patients reporting satisfaction with the procedure in the autogenous group and 89% in the allogenic group. Oral function significantly improved in both groups, with arbitrary values of 8.5 (SD ± 1.2) in the autogenous group and 8.3 (SD ± 1.1) in the allogenic group. Conclusion: Both autogenous and allogenic bone blocks are effective in augmenting deficient alveolar ridges, with comparable outcomes in terms of bone volume gain, complication rates, patient satisfaction, and oral function improvement. The choice between the two should consider factors such as donor site morbidity, availability, and patient preferences
