    Background: Dental implants are most opted treatment modality, especially in the last three decades because they not only replace lost teeth but also provide permanent restorations that do not interfere with oral function or speech or compromise the self-esteem of a patient. Aim: The aim of this study is to use gray scale value (GSV) obtained from cone beam computed tomography (CBCT) scan and derives a precise value of bone density in any region of jaw. This can aid in apt treatment planning and caution during the surgical placement of dental implants. Materials and Methods: A sample of 35 CBCT scans was chosen by randomized sampling method from collection of computerized database of the institution. The clinician’s interpretation about bone quality at site indicated for implant placement was taken before mathematical calculations (Group 1). The GSVs were noted at coronal site where the crest of implant is planned (Group 2) and at apical sites where the apical part of implant is expected to end (Group 3). A mathematical formula correlating Hounsfield unit (HU) and GSV was used: HU = −61.098 + 1.178 × GSV. All the three groups were compared and statistically analyzed. Results: The results of data of the present study showed a statistically significant difference between the groups when Kruskal–Wallis test was performed (P < 0.05). Conclusion: In this study, HU was derived from GSVs obtained from CBCT, using a mathematical formula derived by Razi et al. This provided the exact bone quality in region required. The estimation of exact bone quality at surgical site can help clinicians, interpret, and plan osteotomy before commencement of treatment.
