本研究は、全歯に顕著な歯の摩耗、咬合の垂直寸法の減少、咀嚼筋の疲労を呈した患者の臨床症例報告である。咬合接触、咬合の垂直寸法、下顎の位置に応じて調整された筋弛緩装置と下顎・上顎オーバーレイ装置を使用した治療を提案し、その効果を確認した。得られた結果は、関係する筋肉を弛緩させ、顔面下3分の1の寸法を回復させ、嚥下、咀嚼、発声の機能的活動の点で満足のいくものであった。

This work is a clinical case report of a patient presenting with marked tooth wear in all teeth, a reduction in the vertical dimension of occlusion, and fatigue in the muscles of mastication. The treatment proposed and effected used a muscle-relaxing appliance and mandibular and maxillary overlay appliances which were adjusted according to the occlusal contacts, vertical dimension of occlusion, and the mandibular positioning. The results obtained were satisfactory in terms of relaxing the muscles involved, reestablishing the dimensions of the lower third of the face, and the functional activities of deglutition, mastication, and speech.
