effect of edge to edge bite in different skeletal classes on the position of the condyle

ABSTRACT

This study was carried out to evaluate the effect of edge to edge bite on different skeletal classes on the condylar position within the glenoid fossa at centric occlusion. The study was performed on a total sample of 35 subjects [20 control with accepted occlusion, 5 with skeletal Class I, 5 with skeletal Class II and 5 with skeletal Class-III]. Skeletal class I, II and III subjects charactarised by an edge to edge bite. The mean age of the subjects was 24.3 years. Lateral oblique transcranial radiographs for right and left sides of TMJ were carried out. TMJ computer analysis were performed for each subject. This study revealed that the condyle in skeletal Class III subjects was more anteriorly displaced. In skeletal Class II subjects, it was found that the distance between the condyle and the temporal curve was increased
