Wilson curve

from Wikipedia, the free encyclopedia
Wilson curve

The Wilson curve , also known as the transverse compensation or occlusion curve, is a term from dentistry and describes the lingually tilted angular position of the posterior teeth when the teeth of a full denture are set up . It is named after George Henry Wilson (1855–1922).

nature

It is a connecting line between the buccal cusps of the mandibular posterior teeth over the deeper lingual cusps on one side over the lingual cusps to the buccal cusps on the other side. Due to the alignment of the crown , there is no straight line, but a curve whose lowest point is in the middle of the two rows of teeth.

meaning

The Wilson curve is important when setting up the artificial teeth in the calotte articulation of full dentures . The posterior teeth of a lower jaw prosthesis are set up - from the chewing surface - against a dome-shaped arched template and form a transversal compensation curve. In this way, a bilateral “balanced” occlusion is achieved later in function (when chewing). The curvature of the calotte depends on the inclination of the cusp of the denture teeth and the inclination of the condylar path. The inclination of the condylar path is the inclination of the articulated path against the Camper plane , or the Frankfurt horizontal . The application of the Wilson curve has its origin in the Monson calotte theory . Then the tooth axes of all maxillary teeth meet at a common point, which is in the area of ​​the cockscomb ( Latin : Crista galli ) of the ethmoid ( Latin : Os ethmoidale ). The chewing surfaces lie on the curved surface of a segment of a sphere with a diameter of 28.8 cm.
