What is required during correction preparation for recontouring of the occlusal surface?

The requirement that the occlusal surface should not be felt flat is essential during correction preparation for recontouring. A flat occlusal surface can compromise the function of the teeth, affecting mastication and overall dental health. An ideal occlusal surface maintains appropriate contours that allow for proper occlusion and functional dynamics, encouraging natural tooth movement and alignment.

Maintaining a surface that is not flat ensures that there are optimal contacts with opposing teeth, which supports adequate force distribution during chewing. This also enhances aesthetic appearances, as well-contoured surfaces contribute to the overall silhouette of the dental arch. The goal is to promote healthy occlusion while avoiding excessive wear on teeth and potential for interference during function.

In contrast, striving for a flat crown would create an undesirable situation where tooth anatomy is not respected, leading to potential complications or failure of dental restorations. Similarly, ensuring no contact with adjacent teeth may not align with proper functional occlusion principles, as neighboring teeth require appropriate contact for stability and function. Lastly, while the surface should have a certain level of smoothness, simply being felt flat does not fulfill the requirements for an optimally functioning occlusal surface.
