- Abstract
Brief Background To evaluate the stress characteristics at implant-bone interface due to insertion torque during implantation by using finite element analysis. Material Four implants (Cortex Dynamix Premium) of various lengths and diameters were taken for the study. The dimensions were measured with digital vernier caliper and designed with software ‘Pro/ENGINEER Wildfire 4.0’. Solid modelling of the mandible was done using CT scan software ‘MIMICS 10.0’. The implant and the mandible models were exported to software ‘ANSYS Workbench 14.0’ for assembling the mandible and implant model. Then the models were imported into software ‘ANSYS MECHANICAL APDL 14.0’. Insertion torques of different values (30N, 40N, 50N) were applied for each model. The results were observed and statistical analysis was done. Discussion When torque was increased, stress in bone was also increased (r =0.083, p=0.798). Implant with more diameter would produce more stress (r=0.470, p=0.123) and implant with more length would produce less stress (r= -0.689, p=0.013). Summary and Conclusions This study shows an important correlation with insertion torque, implant dimensions and stress generation. Further research with more accurate bio-simulation and more samples have future scope to establish a more significant result.
