摘要: 目的:探讨应用IPS e.max Press热压铸瓷对牙列重度磨耗患者进行咬合重建修复的可行性,并总结全瓷修复体的制作经验。方法:为1例牙列重度磨耗患者制作全瓷修复体,进行咬合重建。通过3个月暂时性修复体的试戴与咬合调整,建立最适下颌位,在此位置上设计和制作全瓷修复体。用面弓将上颌平面准确转移至半可调式架上,后牙蜡型采用功能性咬合熔模成形法,精确恢复牙解剖外形和咬合关系,前牙制作中形成前牙诱导咬合关系。修复后随访24个月,进行效果和功能评价。结果:随访24个月,患者修复后对外形、咀嚼功能满意,X线检查基牙牙周膜正常,无牙槽骨吸收迹象,颞下颌关节稳定。修复体检查结果显示,边缘密合,牙龈颜色、形态自然,无牙龈炎,修复体色泽自然逼真,未出现破裂、崩瓷、脱落、基牙冠折等并发症。结论:采用IPS e.max Press热压铸瓷治疗牙列重度磨耗,进行咬合重建的效果令人满意。

Abstract: PURPOSE: To investigate the feasibility of occlusal reconstruction with IPS e.max Press for patients suffering from severely worn dentition, and to summarize the technological experience. METHODS: IPS e.max Press was used to reconstruct occlusion for one patient with severely worn dentition. Provisional restorations were fitted in worn teeth to rehabilitate the vertical dimension and centric relationship almost 3 months before final treatment. Face bow was used to transfer the general information of provisional restorations to articulator, including the plane of occlusion, anatomical outline and intercuspal position of teeth. RESULTS: After 24 months of follow-up, the masticatory efficiency and facial appearance were improved significantly, and TMJ disorder was not observed. The patient was satisfied with the prostheses.CONCLUSIONS: IPS e.max Press is an effective and reliable treatment of occlusal reconstruction.The short term effect is promoting.
