Effect of deep overbite correction on mandibular rotation. An application of the centrographic analysis [CGA]

ABSTRACT

The aim of the present study was to evaluate the effect of bite opening using a fixed flat anterior bite plane oil rotation based on a non- numeric lateral cephalographic analysis: Centrographic analysis. A sample of seven female subjects aged 12-14 years old, presented with deep overbite was selected. Subjects manifesting Angle's class I or class II malocclusions with horizontal growth pattern were included. Diagnosis of the subjects was based on non-numeric Centrographic analysis of the pretreatment lateral cephalographs against conventional numeric cephalometric analysis. After a six month study period treatment changes were analyzed graphically by the Centrographic approach against statistical analysis of the numeric data collected from the conventional cephalometric approach. Results drawn through both lateral cephalograhic analyses confirmed the efficiency of fixed anterior bite plane in improving the mandibular rotation, thus inducing more vertical facial harmony. Such, the synchronization of the results produced from both analyses ascertained the validity of the Centrographic analysis in evaluating orthodontic treatment changes on individualized basis during our daily clinical practice
