Investigation of the mechanical properties and propagation of cracks in prosthetic teeth composed of porcelain and dental ceramics using cohesive meshing under quasi-static loading conditions

Abstract

With the significant progress in dental science and the reliance of dental researchers on understanding the mechanical properties and behaviors of teeth and materials used for tooth replacement, there is an increasing demand for study and research in this sector. Composite samples, dental porcelains, and materials used in 3D printers have gained significance as substitutes for human teeth. Therefore, it is crucial to conduct research and analyze these materials' physical and mechanical characteristics compared to human teeth. Tooth damage and fracture may arise from various causes, such as falls, sports-related incidents, or traffic accidents. Tooth fractures may vary in severity, ranging from mild fractures that include chipping of the tooth's surface layers, known as enamel and dentin, to more serious ones, such as diagonal, vertical, or horizontal fractures extending into the root of the tooth.
