Evaluation of buccolingual and linguobuccal implants in the atrophic posterior mandible: A finite element analysis study

This study aims to evaluate the stress distribution on buccolingual and linguobuccal tilted implants in the atrophic posterior mandible using finite element analysis. Twelve digital models of implants with varying lengths (8.5 mm, 10 mm, 11.5 mm) and angles (20°, 25°) were created. These implants were analyzed under 150 N vertical and oblique forces to assess stress distribution on both implants and surrounding bone. Linguobuccal implants generally exhibited lower maximum principal stress in cortical bone, while buccolingual implants showed lower minimum principal stress. Longer implants reduced stress under oblique loading. Tilted implants, particularly using the linguobuccal method, are effective for stress distribution in the atrophic posterior mandible. Further research should explore varying implant diameters and multiple placements for optimization. [Display omitted]
