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.
