Finite Element Analysis of a Dental Crown Using ANSYS

Team 5 David Butler Jr. Radwan Kalo Matt Kayal David Pitchure Cynthia Quinn

Objective Study the effects of stresses on the proposed dental crown material, a glass ceramic (Dicor/MGC).

Description The figure below illustrates the dentine, cement, Dicor/MGC, and enamel. This shows the simulation of occlusal contact between tooth enamel and a ceramic dental crown. Constraints

Refined Mesh In High Stress Region

Biting Simulation

Crack Propagation This study focuses on the generation of stress and crack propagation over time due to a pressure of approximately 7 MPa applied to the ceramic crown.

Initial Stress Distribution

Crack Initiation

Crack Propagation

Crack Propagation Through Crown Model

Crack Propagation with Void In Cement This study focuses on the case where a void exists between the ceramic crown and the dentin structure. This model illustrates realistic conditions due to uneven distribution or degradation of cement.
