摘　　要：目的:通过e.Max单端全瓷翼板桥修复老年患者单颗前牙缺失,并对其中短期临床应用效果进行评价,为其临床应用提供参考依据。方法:选择于2005年10月-2012年9月之间就诊于中日友好医院口腔医学中心。共入组13人,其中男性8人,平均62.2岁;女性5人,平均64.3岁。恢复上颌侧切牙3例,上颌第一前磨牙1例;恢复下颌中切牙5例,下颌侧切牙4例;应用VariolinkⅡ作为树脂粘接剂,常规进行粘接。针对修复体的完整性、邻接关系、咬合关系和基牙牙髓活力以及患者的满意度进行每年一次的随访。结果:平均观察期为60.5个月,所有修复体无1例表现术后敏感和继发龋,无连接体折裂、饰瓷崩脱、基牙移位或松动。1例患者单端桥体切端3年随访时出现早接触,给予调牙合。结论:应用e.Max瓷贴面固位的单端全瓷翼板桥修复老年患者咬合负荷不大的单颗牙缺失可以实现微创修复效果,具有较好的临床应用效果。Objective： To evaluated the clinical outcomes of cantilevered veneer-retained fixed partial dentures（VRFPDs） fabricated with IPS e.max Press for single-tooth replacement in the anterior arch for the aged patients.Methods： A total of 13 patients were treated with VRFPDs,including 4 cases in the maxilla and 9 in the mandible.The patients were evaluated at baseline and annually from October 2005 to Sep 2012 for the integrity of the VRFPDs,proximal contacts,occulsal relationships,pulp vitality,and tooth mobility.The degree of satisfaction was indicated with a visual analog scale.Results： During a mean observation time of 60.5 months,13 VRFPDs on vital abutment teeth did not exhibit postoperative sensitivity or secondary caries.No fractures or chipping of the restorations occurred within the course of the evaluation.No patient complained of food impaction.One cantilevered pontic needed adjustment on the incisal edge due to premature contacts after the 3-year recall examination.Conclusion： Cantilevered IPS e.max Press VRFPDs should be considered as minimally invasive,single-tooth restorative strategy in the anterior arch for the aged patients.Longer observation periods are necessary before this type of restorative design can be recommended as a general conservative procedure.
