Abstract

<p>Patients with occlusal collapse tend to develop masticatory habits due to the abnormal position and tooth defects, which cause hypertonia and hyperlaxity of the muscles and changes in the mandibular position. Postural changes often occur, resulting in systemic symptoms such as headaches, stiff shoulders, back and knee pain. When performing occlusal reconstruction in such patients, we aim to improve and maintain oral and systemic symptoms by evaluating not only the oral cavity but also postural changes. According to the guidelines of the JapanProsthodontic Society, occlusal abnormalities not only affect the balance of the head and neck musculature, but also greatly affect the balance of the whole body, causing malalignment of the trunk, pain and movement disorders in the shoulders, arms, and backs, etc. On the contrary, various mandibular positions (mandibular rest position, terminal position of habitual jaw closure, muscle position, etc.) are affected by posture (head position), and may change to a certain extent. In addition to the diagnostic examination including intraoral photography, periodontal examination, evaluation of defects, radiographs, temporomandibular joint and dental cast evaluation, postural changes were also evaluated. The mandibular position was evaluated by comparing the Gothic arch tracing at the initial examination and upon fitting of the provisional resotrations. Registration of a madibular position with incorporation of postural analysis and the elimination of the tilt and rotation of the whole body to the greatest extent possible might contribute to the long-term stability of the mandibular position. </p>
