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

The appropriate occlusion rim height for the mandibular arch is generally around 18 mm. This height is crucial for achieving optimal occlusion and function, as it helps to establish a proper relationship between the maxillary and mandibular arches during restorative procedures or denture fabrication.

An occlusion rim height of 18 mm allows for adequate space for the interarch distance, facilitating functions such as mastication and phonetics. It also plays a significant role in providing stability and support for the contours of the prosthesis, ensuring that the patient can chew effectively and comfortably.

Choosing a height that deviates from this standard may lead to issues with occlusal relationships and patient comfort, making it essential for practitioners to adhere to established guidelines when determining occlusion rim heights in the mandibular arch.
