[Does traumatic occlusion change the jaw relations?]. 1979

K Fuhr, and P Gresser

Jaw relations were established via squashbites, and the deviations from habitual intercuspidation were measured. The evaluation of 252 squashbites indicated that 1. The mandible deviated as a result of the squashbite. The deviations are not related to the side and almost always lead to an increase in vertical jaw relations. 2. Primarily lateral deviations of the mandible are observed with unilateral squashbites. 3. Simultaneous bilateral squashbites, on the other hand, lead to left as well as right lateral deviation of the mandible. 4. The absolute values of the deviations in the sagittal direction are lowest in the middle; those directed ventrally are slightly more predominant. 5. Compared with materials containing siloxane, squashbites with plaster casts revealed no significant alterations in the qualitative deviations. 6. In terms of direction and extent, deviations of the mandible (primarily sagittal) depend on occlusal factors.

D000328	Adult	A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available.	Adults
D014716	Vertical Dimension	The length of the face determined by the distance of separation of jaws. Occlusal vertical dimension (OVD or VDO) or contact vertical dimension is the lower face height with the teeth in centric occlusion. Rest vertical dimension (VDR) is the lower face height measured from a chin point to a point just below the nose, with the mandible in rest position.
