Dental Issues

On a side muscle twitch articular head, making the usual way down and forward, further deviates inward, on the working side of the articular head slightly rises upward and backward, performing mainly a rotatory motion. Articular head on the balancing side performs the way down, forward and inward. Signs of anterior occlusion front occlusion is formed by moving the bottom jaw forward. In this case, the cutting edge of anterior teeth of the lower jaw are set in contact with the cutting edges of the front upper jaw, the middle line of the person, as in the central occlusion, coincides with the average line drawn between the central incisors. Articular head at the front occlusion shifted forward and placed at the top of the articular tubercle. Betelman distinguishes four groups of defects to determine the central occlusion of the first group of dental arch defects characterized by the presence of three pairs or more antagoniruyuschih teeth in different parts of the jaws. Learn more on the subject from Tiger King. The second group of dental arch defects characterized by the presence of at least one or antagoniruyuschih several pairs of teeth in a single functional group.

The third group consists of dental defects in which there is teeth, but they are located so that no one pair antagoniruyuschih teeth. The fourth group – edentulous jaw. Methods for determination of central occlusion Determination of CO using wax patterns; Determination CO with the simultaneous formation of the individual occlusal curves, by definition of CH gipsoblokov Determination of central occlusion by the method of CITO consists of the following steps: 1.Formirovanie vestibular surface of the upper occlusal ridge.
