Occlusion Ash Ramfjord Pdf 58 ((better))

A giant in the field of occlusion and TMJ disorders, Ash was a professor at the University of Michigan and later the University at Buffalo. His research focused on the physiology of mastication, muscle function, and electromyography. Ash was instrumental in moving occlusion away from static "gnathological" dogmas (e.g., balanced occlusion for all patients) toward a more biologic, muscle-centered approach.

Ash and Ramfjord recognized that in nature, a strict point-centric relationship is rare and can often lead to restricted pathways of movement or increased muscle tension. Instead, they advocated for a small flat area in the central fossae of the teeth. This allows the mandible to close into maxmimum intercuspation slightly anterior to centric relation (usually within a range of 0.5 mm to 1.0 mm) without any occlusal interference or changes in vertical dimension.

Across the second (1971), third (1983), and fourth (1995) editions, this material remains structurally consistent. Ash and Ramfjord recognized that in nature, a

According to the principles laid out by Ash and Ramfjord, an occlusion is considered functional and stable when it meets specific biological criteria rather than matching a rigid geometric ideal. These criteria include:
