目的

探讨颌骨纤维异常增殖症（FD）伴牙列重度磨耗的口腔修复方法。

方法

对1 例颌骨FD 伴牙列重度磨耗的患者进行口腔系统检查与修复设计。完成修复前准备之后，试戴下颌过渡性垫，观察4 周；行上前牙及上颌第一前磨牙牙冠延长术，4 周后行上下颌牙体预备和精细临时冠桥修复，根据临时冠桥参考模型，对上下牙均行两段式钴铬生物合金烤瓷长桥修复。

结果

修复后患者面容对称，口唇自然美观，义齿逼真，感觉舒适，咀嚼有力，患者对修复体的临床效果满意。

结论

对于颌骨FD 伴牙列重度磨耗患者的口腔修复，根据适应症选择合适的修复方案，进行上下颌牙列的固定桥修复可以取得良好的修复效果。

Objective

To explore the restorative procedures of dentition serious attrition caused by fibrous dysplasia.

Methods

A patient with serious dentition attrition caused by fibrous dysplasia of jaw received oral system examination and prosthetic design.Transitional occlusal pad was used for four weeks.Crown lengthening surgery was performed for anterior teeth and first premolor of the maxillary after the preparation of restoration.Four weeks later， subtle fixed partial dentures were made after abutment teeth preparation， according to which reference models were designed.The perpetual prostheses of Co-Cr alloy were all divided into two parts.

Results

The patient had good appearance， comfort and mastication， and she was satisfied with the effect.

Conclusion

For patients of fibrous dysplasia， maxillary and mandibular dentition can be well restored by fixed dentures if proper indications are selected.
