Aim and objective: Evaluation and comparison of insertion torque (IT) and the implant stability of two different implant macrogeometry in different bone densities using resonance frequency analysis.

Materials and methods: A total of 48 implants (with two implant types having regular and novel macrogeometry) were classified into 4 groups with 12 samples in each group. Group A regular implant without surface treatment, group B regular implant with surface treating, group C novel implant deprived of surface treating, and group D was new dental implant with surface treatment were used. Implant stability quotient (ISQ), implant IT, removal torque (RT) percentage, and torque reduction percentage were calculated. Results: The mean±SD ISQ value of bone 1 in group A was 56.7±3.2, in group B was 58.6±2.4, in group C was 57.1±3.5, and in group D was 59.3±2.9. In bone 2, the value was 57.8±1.4, 59.5±1.5, 58.2±2.6, and 59.5±2.4 among A, B, C, and D groups correspondingly. In bone 3, it was 59.4±2.4, 60.3±2.3, 60.4±2.8, and 62.7±2.5 among A, B, C, and D groups correspondingly. In bone 4, it was 67.2±3.4, 69.5±2.7, 68.7±2.4, and 69.4±2.3 among A, B, C, and D groups correspondingly. There was a substantial difference in IT and nonsignificant difference in RT in different groups.

Conclusion: There was a low IT value with new implant macrogeometry as compared to regular implant macrogeometry. There was absence of association between IT and implant stability.

Clinical significance: Calculation of torque insertion score helps in implant placement. Higher bone density scores produce a higher option of decreasing the initial torque. Low IT of new implant types is useful to reduce failure.
