Abstract

Background: Inlay is a restoration that is fabricated outside the oral cavity and placed in a prepared to sometimes the bevel is placed at surface margins to enhance the marginal integrity. The biomechanical study of the tooth with an indirect restoration presents difficulties in many aspects such as the complexity of the two structure study materials boundary condition cavity shape dimension and the stress. The success of restoration depends on stress and the physical properties of the material used due to which the restorative materials must be evaluated under compressive loadings. In this three-dimensional finite element analysis (FEA) two indirect tooth-colored restorations are studied under the impact of mechanical loads and the stress distribution level is analyzed. Bevels are placed in anterior esthetic restoration in composite restorations that enhance the esthetics and strength of the restoration. Materials and Methods: A single extracted maxillary first pre-molar was collected and stored in saline. That tooth is mounted on a wax rim and cone beam computed tomography scan model is used in FEA using ANSYS software. For analysis, two groups were formed group 1 inlay cavity with bevel and group 2 inlay cavity without bevel. Two different restorative materials composite and ceramics were used in groups 1 and 2. Results: Bevel has more advantages in inlay ceramic restoration then composite. Composite with bevel shows more overall deformations and stress. Conclusion: Based on our study in inlay cavities with bevel the material of choice should be ceramic restorations over composite restorations.
