Wear patterns in dental materials are critical to understanding their performance and longevity in extensive tooth replacement treatments. Modern materials such as ceramics, composites, and hybrid polymers have been developed to replicate the natural characteristics of enamel and dentin, balancing mechanical strength and aesthetic properties. Despite their advancements, these materials are subjected to wear mechanisms, including attrition, abrasion, and erosion, which affect their functionality over time. The integration of nanotechnology and computer-aided design and manufacturing (CAD/CAM) has contributed to improvements in material durability and precision, enabling restorations that closely mimic natural teeth. Research has revealed that wear resistance in dental materials depends on a variety of factors, including material composition, hardness, and elasticity. These properties influence the interaction between the restorative material and opposing dentition, often resulting in differential wear patterns. For example, harder materials may preserve their integrity but cause accelerated wear on natural teeth, whereas softer materials may degrade more rapidly under occlusal forces. Innovations such as nanocomposites have demonstrated enhanced stress distribution and resistance to surface degradation, offering promising results in clinical applications. Patient-specific factors, including dietary habits, bruxism, and occlusal dynamics, further impact the wear behavior of these materials. Environmental factors, such as pH variations and thermal cycling, also play a role in material degradation. Emerging technologies and biocompatible materials aim to address these challenges by optimizing wear performance while maintaining structural integrity. However, the need for extensive in vivo studies and long-term evaluations persists to validate their effectiveness and reliability. Understanding the wear characteristics of dental materials is essential for their selection and application in restorative dentistry, particularly in cases requiring extensive tooth replacement. Advances in materials science and fabrication techniques continue to drive innovation, improving patient outcomes and the longevity of restorative treatments.
