During functional veneer crown preparation, what should the occlusal clearance be on the functional cusp?

In functional veneer crown preparation, the recommended occlusal clearance on the functional cusp is 1.5mm. This measurement is critical as it provides adequate space for the material while ensuring that the crown achieves the necessary strength and esthetics.

A clearance of 1.5mm allows for the adequate thickness of the restorative material, which is vital for durability and functionality. It also helps prevent potential issues such as under-contouring, which can lead to insufficient occlusion, or over-contouring that may result in aesthetic discrepancies or functional problems during mastication.

In addition, this amount of clearance ensures that there is enough room for preparing the tooth structure and accommodating the anatomy of the functional cusp, which plays a significant role in the occlusion and overall bite mechanics. Therefore, the 1.5mm specification serves as a standard guideline in dental practice for optimal outcomes during functional veneer crown preparations.
