What is the recommended clearance on the nonfunctional cusp after occlusal reduction?

The recommended clearance on the nonfunctional cusp after occlusal reduction is 1.0 mm. This clearance is critical in ensuring that there is adequate space for the material used in the prosthesis, whether it be a crown or another type of restoration. Adequate clearance prevents lateral compression and excessive wear during function, ultimately contributing to the longevity and effectiveness of the dental restoration.

In prosthodontic practice, this specific measurement helps maintain proper occlusion and avoids any potential interference between opposing cusps. Over-reduction can lead to a compromised restoration that may not withstand the forces of occlusion, while under-reduction might result in a lack of adequate space for the material, which could compromise the integrity and performance of the dental appliance over time. Therefore, adhering to the 1.0 mm clearance for the nonfunctional cusp is essential for achieving optimal functional and esthetic outcomes in prosthetic dentistry.
