Master Project Report: Dental Bridge Fatigue Lifetime Prediction

This report, submitted for a Master's project at Western Sydney University, investigates the fatigue lifetime prediction of all-ceramic dental bridges. The study delves into the use of ceramic materials in dentistry, highlighting the importance of understanding their behavior under cyclic loading and various stresses. The research explores the mechanical properties of ceramics, including flexure strength and fracture toughness, and examines the impact of microstructural degradation on their performance. The project aims to predict the lifetime of dental ceramics, considering factors like the pH of the oral environment and the mechanical forces exerted during chewing. The report reviews existing literature, analyzes preliminary results, and outlines the research plan, with the ultimate goal of providing insights that can assist clinicians in selecting appropriate ceramic materials for dental procedures and improving patient outcomes. The study also addresses the challenges in designing ceramic structures and the influence of thermal stimuli on ceramic bridge degradation, emphasizing the need for materials with high tensile strength and hardness to mitigate abrasion and friction. The findings are expected to contribute to a better understanding of ceramic fracture and failure, ultimately leading to more durable and reliable dental prostheses.
