Question: 1 / 400

What is the recommended occlusion rim height for the mandibular arch?

18 mm

The recommended occlusion rim height for the mandibular arch is typically around 18 mm. This dimension is crucial as it allows for proper positioning of the occlusion rims to ensure they accurately represent the functional occlusal relationship between the maxillary and mandibular arches. The height should facilitate optimal articulation during the assessment and fabrication of dental prosthetics. Setting the occlusion rim at this height helps dental professionals evaluate the occlusion and refer to standard measurements for creating dentures or other dental devices, ensuring that they achieve a functional fit and aesthetic appearance.
