The aim of the study was to explore the efficacy of bone density value derived from CBCT by evaluating its correlation with implant stability parameters including insertion torque value [ITV] and resonance frequency analysis [RFA]. A total of 20 patients in the age group of 20- 65 years attending department of prosthodontics, Sibar Institute of Dental Sciences were selected for the study during the period of 2017-2019 with either fully or partially edentulous region. Alpha bio Implant system was used in the present study. Patients were divided into two groups; Group-A and Group-B. In Group- A patients, 10 implants were placed in D1 bone density and in Group B, patients 10 implants were placed in D2 bone density. Osteotomy site was prepared, the implant with dimension 3.75×10mm placed in the osteotomy site. Implant was tightened by torque wrench during placement. Insertion torque values [ITV] were obtained. After placing resonance frequency was checked by osstell mentor. ISQ values were recorded. Implant stability increased as bone density increased. The present study was done to establish the relation between pre-surgical assessment of bone density values derived from CBCT and implant stability parameters and thus estimated the implant survival rate and loading protocol. Within the limitations of the study, bone density showed correlation with implant stability which means as the bone density increases implant stability increases. This suggests that bone quality is one of the factors that require evaluation preoperatively. In the present study the mean ITV and ISQ values were significantly higher in D1 group when compared to D2 group.
