Tooth tissue loss from bruxism has been demonstrated to be associated with various dental problems such as tooth sensitivity, excessive reduction of clinical crown height, and possible changes of occlusal relationship. A literature search revealed a number of treatment modalities, with an emphasis on prevention and rehabilitation with adhesive techniques. Rehabilitating a patient with bruxism-associated tooth tissue loss to an acceptable standard of oral health is clinically demanding and requires careful diagnosis and proper treatment planning. This article describes the management of excessive tooth tissue loss in a 43-year-old woman with a history of bruxism. The occlusal vertical dimension of the patient was re-established with the use of an acrylic maxillary occlusal splint, followed by resin composite build-up. Full-mouth oral rehabilitation ultimately involved constructing multiple porcelain veneers, adhesive gold onlays, ceramo-metal crowns, and fixed partial dentures.
磨牙症导致的牙齿组织丧失已被证明与各种牙科问题相关，如牙齿敏感、临床冠高度过度降低以及咬合关系可能发生变化。文献检索揭示了多种治疗方式，重点是采用粘结技术进行预防和修复。将患有磨牙症相关牙齿组织丧失的患者恢复到可接受的口腔健康标准在临床上要求很高，需要仔细诊断和恰当的治疗计划。本文描述了一名有磨牙症病史的43岁女性牙齿组织过度丧失的治疗情况。通过使用丙烯酸类上颌咬合板重新建立患者的咬合垂直距离，随后进行树脂复合材料堆积。全口口腔修复最终包括制作多个瓷贴面、粘结金嵌体、烤瓷熔附金属冠和固定局部义齿。
