Abstract EN
The study was to investigate the impact of orthotropic material on the biomechanics of dental implant, based on a detailed mandible with high geometric and mechanical similarity.
Materials and Methods.
Multiple data sources were used to elaborate detailed biological structures and implant CAD models.
In addition, an extended orthotropic material assignment methodology based on harmonic fields was used to handle the alveolar ridge region to generate compatible orthotropic fields.
The influence of orthotropic material was compared with the commonly used isotropic model and simplified orthotropic model.
Results.
The simulation results showed that the values of stress and strain on the implant-bone interface almost increased in the orthotropic model compared to the isotropic case, especially for the cancellous bone.
However, the local stress concentration was more obvious in the isotropic case compared to that in orthotropic case.
The simple orthotropic model revealed irregular stress and strain distribution, compared to the isotropic model and the real orthotropic model.
The influence of orthotropy was little on the implant, periodontal ligament, tooth enamel, and dentin.
Conclusion.
The orthotropic material has significant effect on stress and strain of implant-bone interface in the mandible, compared with the isotropic simulation.
Real orthotropic mechanical properties of mandible should be emphasized in biomechanical studies of dental implants.
