Association of condylar angle with incisal wear and myofunctional therapy – Original Research

ABSTRACT

Introduction: In any normal dentition there is stable relationship between the morphology of the occlusal facets and the movement of the condyles. Change in one of these are compensated by reactive adaptation of another. In the present study, the relation between the incisal wear facets and the condylar inclination were evaluated by checking the changes in condylar angle measurements in patients with incisal wear and those without it. The effect of myofunctional therapy on condylar angle and its correlation pre and post treatment was also established. Materials and Methods: The case group included 50 patients with incisal wear (attrited mandibular incisors) and the control group included 50 patients without incisal wear. 44 samples were taken to evaluate the changes in condylar angle pre and post myofunctional therapy. The posterior slope of articular eminence was marked in the lateral cephalogram and the horizontal condylar angle was drawn by tangent method. Results and Conclusion: The steepness of the condylar angle was found, directly proportional to the mandibular incisal wear. There was decrease in the values of condylar angle in patients after treatment with myofunctional therapy when compared with the pre-treatment values.
