What is an important feature of the occlusal surface of provisional coverage?

The occlusal surface of provisional coverage is designed to provide a proper functional relationship and aesthetic appearance while the permanent restoration is being fabricated. When the occlusal surface remains flush with the adjacent teeth, it ensures that there is no premature contact or interference during function, which could lead to discomfort or occlusal issues. A smooth, flush occlusal surface contributes to proper chewing function and helps in maintaining alignment and spacing with the adjacent teeth.

Maintaining this flush alignment also helps in reducing the risk of complications such as gingival irritation or excessive wear. In contrast, features such as an uneven alignment with adjacent teeth could disrupt bite function, while extending beyond the prepared margin may create an improper seal or cause discomfort. Moreover, simply covering temporary cement does not encompass the functional or aesthetic roles that provisional coverage needs to play; instead, the focus should be on overall occlusal harmony.
