In centric occlusion, the ML cusps of maxillary molars occlude where?

In centric occlusion, the mesiolingual (ML) cusps of maxillary molars typically occlude with the central fossa of mandibular molars. This relationship is critical in ensuring a stable and functional occlusion during chewing and other dental functions.

The position of the ML cusps is strategic; they are integral for effective force distribution and overall occlusal harmony. When the maxillary molars come in contact with the mandibular molars, the ML cusp fits into the central fossa, providing optimal interdigitation. This occlusal relationship contributes to better periodontal health, as it minimizes the risk of wear and potential damage to both opposing teeth.

Understanding this occlusal relationship is fundamental in dental practices, as it aids in diagnosing any occlusal discrepancies or making necessary adjustments during restorative procedures. Proper occlusion ensures that the forces generated during biting and chewing are appropriately managed, thereby preserving the health and longevity of both the teeth and the supporting structures.
