Modeling fracture in multilayered teeth using the finite volume-based phase field method.

The present work, utilizing the finite volume-based phase field method (FV-based PFM), aims to investigate the initiation and propagation of cracks in the second molar of the left mandible under occlusal loading. By reconstructing cone beam computed tomography scans of the patient, the true morphology and internal mesostructure of the entire tooth are implemented into numerical simulations, including both 2D slice models and a realistic 3D model. Weibull functions are introduced to represent the tooth's heterogeneity, enabling the stochastic distribution characteristics of mechanical parameters.

Is hyperglycemia the only risk factor for implant in type 2 diabetics during the healing period?

Objective: To determine whether risk factors other than hyperglycemia lead to failed osseointegration in patients with type 2 diabetes mellitus (T2DM) during the healing period.

Materials And Methods: We compared the success rates between patients with and without T2DM during the healing period at our center. Bone marrow mesenchymal stem cells (BMSCs) were cultured from subjects.
