Background: The insertion of dental implants has become an increasingly common procedure in the oral rehabilitation of partially and totally edentulous patients. The present study was conducted to evaluate bone quality at implant site with CBCT. Materials & Methods: The present study was conducted on 82 partially edentulous patients of both genders. All underwent CBCT taken with Kodac machine operating at 120 kVp, 12 mA and 17 seconds exposure. Bone quality was labeled as D1, D2, D3, D4 and D5 based on Hounsefield units. Results: Out of 82 patients, males were 32 and females were 50. The mean HU at anterior maxilla was 864.2, at anterior mandible was 1280.2 HU, at posterior maxilla was 324.2 HU and at posterior mandible was 732.6 HU. The difference was significant (P< 0.05). Conclusion: Authors found that anterior mandible had maximum density followed by anterior maxilla, posterior mandible and posterior maxilla. CBCT is useful in assessing bone density at implant site based on hounsefield units. Key words: CBCT, Maxilla, Implant.
