What can result from insufficient functional beveling during crown preparation?

Insufficient functional beveling during crown preparation can indeed lead to inadequate thickness of the restorative material. In crown preparations, proper beveling is essential for ensuring that the restorative material has sufficient thickness to withstand occlusal forces and provide the necessary strength for longevity. When the bevel is not adequately defined, it can result in areas of the crown that are too thin, which compromises the structural integrity of the restoration. This thinness can lead to various issues, such as an increased risk of fracture, wear, or even failure of the restoration, ultimately affecting its performance and durability in the oral environment. Thus, emphasizing proper beveling is critical for achieving a successful outcome in crown restorations.
