Description
Summary:The purpose of this follow-up prospective longitudinal study was to determine what changes occurred in the condyle/fossa relationship after treatment. Orthodontic posttreatment records, including corrected tomograms of 106 white patients (58 Class I and 48 Class II Division 1), from a pretreatment sample of 232 patients, were analyzed. The average pretreatment age was 13.6 ± 3.0 years. The average length of treatment was 2.3 ± 0.6 years for the Class I group and 2.8 ± 0.9 years for the Class II Division 1 group. With orthodontic treatment, the condyle became more concentrically positioned, and a significant (P
