The Effect of the Projectile Shape on the Stress Biomechanical Behavior of Dental Implant: Three-dimensional Analysis

The finite element method is used to solve mechanical and physical problems in engineering analysis and design. Primary stability has been regarded as a prerequisite for osseointegration of dental implants. Biomechanical factors play a key role in the success of dental implants. The study of impact velocity is relevant to the biomechanics of dental implants. The purpose of this analysis was to determine the intensity and distribution of stresses in the dental prosthesis elements (crown, framework, implant, abutment, bone) and the sliding at the bone-implant interface under the effect of a mechanical impact of different geometric shape of projectile, this shock simulates a stone throw or other objects coming into contact with the dental prosthesis.
