Stress dissipation in the bone through various crown materials of dental implant restoration: a 2‐D finite element analysis

AIM: To investigate stress transmitted by various restorative materials given for a full veneered implant-supported crown through implants in the bone. METHODS: A 2-D finite element model of dental implant with an abutment and full crown was designed. The materials used for stress dissipation were zirconia, full ceramic, full metal crown, composite crown, and acrylic crown. Adequate boundary conditions were applied, as was a vertical load of 100 N. RESULTS: The highest stress value was exhibited for the zirconia prosthesis model, and maximum stress dissipation for the same model was observed around the cervical region of the abutment and abutment-implant junction (24.877 Mpa). CONCLUSION: Within the limitations of this study, it was concluded that an occlusal material with a low modulus of elasticity, such as acrylic resin, dampens the occlusal impact forces, thereby decreasing its effect on the bone-implant interface.
