Evaluation of Dysfunction of Temporomandibular Disc

Introduction: The most often derangement is disc malposition in relation with mandible condyle and temporal bone. The aim of the study: The aim of this study is to explain the histological changes in loaded and malposition temporomandibular disc in patients with jaw joint disorders.Material and Methods: The examination is done over a group of four female patients with temporomandibular joint disorders. Discussion: Disc malposition known also as disc dislocation is characterized with disc dislocation in joint space when jaws are in close or near closed position. Conclusion: Changes in the organization and composition of the malpositioned disc and posterior attachment tissues are secondary to abnormal loading which induces cell-driven processes of degradation and reassembly of the extracellular matrix.
