Abstract:
The biomechanical performance of short implants with suprastructure on the posterior atrophic mandible was studied for difference of bone-to-implant contact and crown-implant ratio. Six three dimensional (3D) finite element models of a 6 mm. short implant with 6 mm.crown height and 12 mm represented crown-implant ratio of 1:1. and 2:1. Respectively with 30%, 60%, and 90% BIC models. Uniform thickness of the cortical bone model was 1 mm covering the trabecular layer. Axial force of 200 N and oblique force of 75 N were applied to the occlusal surface. Results of axial loading revealed that the maximum von Mises stress of bone is lower than yield stresses, indicating that no bone fracture occurred. Crown-implant ratios and average elastic strain of cortex and trabecular at BIC levels of 60% and 90% were similar. At a BIC level of 30% average elastic strain for 2:1 crown-implant ratio was about twice that of a 1:1 crown-implant ratio. Results of oblique loading, the highest stress was concentrated in the joint of the screw on the mesial side on the crown/implant platform and third thread, and on the cervical third of crown following the loading direction. Comparing the stress distributions, the 1:1 crown/implant ration exhibited a 3 times greater area of stress concentration than the 2:1 crown/implant ratio crown under oblique loading
