An evaluation of eccentric occlusal contacts in orthodontically treated subjects.

An investigation using Citricon base regulations to record the number and type of centric occlusion-initiated eccentric contacts failed to demonstrate a difference between forty-nine treated orthodontic patients and twenty-seven untreated subjects who were judged to have "ideal" static occlusion. Of the treated and untreated subjects, 97 percent and 85 percent, respectively, had nonworking (balancing) side occlusal contacts. This study illustrates that among the orthodontic patients treated at one university the number of eccentric occlusal contacts is similar to that of a sample of untreated subjects.
