Abstract

Conventional dense titanium (Ti) implants cause stress shielding, aseptic loosening and implant failure. This study investigates the effects of porous dental implants (63% porous and 77% porous) with different neck angles (straight, 10^° and 15^°) on the healthy and osteoporotic bone under different loading conditions (axial load and buccolingual load). Simulation results showed that in cortical bone, the von Mises stresses are greater in the case of 77% porous Ti implant A (straight) as compared to implant B and C (10^°, 15^° angled neck). Overall, in the case of the osteoporotic bone, the strains are higher than the healthy bone.
