Numerical analysis of a dental bone implant with design features

Qualitatively new requirements are imposed on modern dental implants for stability in bone tissue and compatibility with it. The article presents a numerical calculation of intraosseous reconstructive cylindrical implants made of NiTi alloy. The stress-strain state is determined in the static calculation of three different geometric models, as well as the advantages and disadvantages of each of them are analyzed. The calculation is carried out by the finite element method. Numerical analysis makes it possible to find a balance between the rigidity of the fastening system and the occurrence of high local stresses.
