An Innovative Non-Compliant Interceptive Approach for 3-Dimensional Class II Defect in Mixed Dentition

The aim of this study was to intercept the Class II Div 1 malocclusion with 3 dimensional defects early in mixed dentition to reduce its severity, so to avoid the psychological trauma, in this poor non-compliant patient, which would also be cost effective. A combination appliance, which would consider all 3 dimension, be cost effective and which would not depend on patient for compliance was a need for this patient. So an innovative approach of using a maxillary expansion plate with the incline plate as that of twin block but which can be cemented to the arch and prism shaped composite blocks as that of Planas Direct Tract on the mandibular second deciduous molar was designed. As soon as the appliance was bonded, profile was improved.Results and At the end of 8 months of active treatment, there was improvement in transverse, sagittal and vertical dimension with the satisfaction of the patient and the parent. The fabricated combination appliance, proved successful for intercepting the condition, satisfying the patient and parent by improving psychological condition along with the Class II condition. It was decided to name the appliance as 3D RDC CORRECTOR [3 dimensional (institution name) corrector].
