What aspect is crucial during the restoration process to minimize deformation?

The aspect that is crucial during the restoration process to minimize deformation is the type of margin design employed. Proper margin design plays a significant role in ensuring that restorations fit accurately within the oral cavity. A well-designed margin can help distribute forces evenly across the restoration and the tooth structure, reducing the likelihood of deformation under occlusal forces.

Margin design affects the retention and resistance form of the restoration, which is essential for maintaining stability over time. For example, a bevel or specific contour at the margins can enhance the flow of restorative material, leading to a more precise fit and minimizing stress concentrations that could lead to deformation. Properly designed margins also facilitate better sealing against microleakage, which is essential for long-term success and prevents issues that might arise from residual stress in the material.

Understanding the role of margin design helps practitioners choose appropriate techniques and materials that enhance the longevity and functional integrity of prosthetic restorations. This foundational knowledge positions dental professionals to provide better care and improved outcomes for patients.
