Occlusion analysis is the study of the relationship of the occlusal surfaces of opposing teeth and their associated functional harmonies. The primary purpose of occlusion analysis is to reveal interferences in articulation which cannot be observed directly in the mouth.

Occlusal adjustment is the scientific grinding and/or reshaping of the occluding surfaces of teeth to develop and improve upon their harmonious relationships between each other, their supporting structures, muscles of mastication, and temporomandibular joints.
