Abstract

The effect of the Eureka Spring appliance, was investigated on 37 consecutively treated, non compliant, bilateral Class II malocclusions, requiring at least 3 mm or more of additional molar correction. The mean pretreatment age of this sample was 13.9 years. All patients were treated by a single clinician utilizing the Eureka Spring. Lateral cephalographs were taken at start of orthodontic treatment (T1), at insertion of Eureka Springs (T2), and at removal of the Eureka Springs (T3). The average treatment interval between T2 and T3 was 4 months. Class II correction occurred almost entirely by dentoalveolar movement, 33% in the maxilla and 60% in the mandible. The rate of molar correction was 0.7 mm per month. There was no significant orthopedic effect. There was no change in anterior face height, mandibular plane angle, palatal planed angle, or gonial angle with treatment. There was a plus 2.3 degree change in the occusal [sic] plane resulting from intrusion of the maxillary molar and the mandibular incisor. Based on this sample the Eureka Spring appliance was very effective in correcting Class II malocclusions in non compliant patients while maintaining the vertical dimension.
