摘　　要：目的:探讨以美容为目的的固定修复治疗所形成的咬合重建对颞下颌关节可能产生的影响。方法:通过固定修复、咬合重建的方法对牙列不齐、面下1/3垂直距离较短的患者,按下颌息止颌位时的面下1/3垂直距离减去2～3mm确定下颌位置并以此为标准进行修复治疗,使患者实现正常的面容及咬合形态,同时观察颞下颌关节(TMJ)的结构和功能的变化。结果:3例前牙超覆、超覆盖,面下1/3垂直距离偏短的患者进行咬合重建,均恢复了正常的咬合形态,改善了咀嚼功能和容貌,同时1例伴有TMJ症状的患者TMJ症状消失。结论:对面下1/3垂直距离不足的咬合畸形患者恢复正常的咬合形态及面下1/3垂直距离,在改善容貌和咬合功能的同时,也去除了TMD的易感(occl us i on)因素,对于缓解或解除TMD症状有良好的效果。Objective To investigate the effects to the TMJ of patients who had malocclusion were treated occlusal reconstruction of esthetic prosthodontics. Methods Three patients,I were crowded malalinment, II were whole dental cross bite, Ill were Angle II malocclusion who had deep over bite,deep over jet,maxillary forward,mandibular retraction, decrease of vertical dimension and symptoms of TMD.Patients I and II were alined teeth by fixed ceramic crowns,not changed mandibular position. Patient Ill were mowed mandible forward and downward according to the mandibular postural position and got occlusal reconstruction by fixed ceramic crowns. Results Three patients who had esthetic occlusal reconstruction rehabilitated normal articulation and improved masticatory movement and face.Symptoms of TMD of patient III disappeared. Conclusion When patients of malocclusion were treated occlusal reconstruction of esthetic prosthodontics,the occlusal factors of TMD were removed and symptoms TMD eliminated.
