摘　　要：背景:IPS e.max Press铸瓷具有极佳的生物相容性和抗腐蚀性,应用于前牙贴面、前磨牙嵌体、高嵌体修复取得了良好的临床效果,但将其应用于磨牙单冠修复的研究较少见。目的:评价IPS e.max Press铸瓷全冠应用于根管治疗后磨牙修复的临床效果。方法:纳入215例患者(患牙324颗),其中男88例,女127例,年龄22-58岁,均采用IPS e.max Press铸瓷全冠进行磨牙修复,修复后随访3年,评估修复体的颜色、形态、折裂、边缘着色,边缘密合度、基牙继发龋及牙龈健康状况。结果与结论:随访3年内,324颗修复体在颜色、形态、边缘密合度、基牙继发龋方面均达到A级标准,3颗修复体折裂,14颗修复体边缘着色,8颗出现牙龈炎症,95%以上的修复体均达A级。结果表明,IPS e.max Press铸瓷全冠用于根管治疗后磨牙修复的失败率较低,临床修复效果良好。BACKGROUND： IPS e.max Press has an excellent biocompatibility and corrosion resistance, which obtains satisfactory clinical outcomes on dental veneers, inlay and onlay restorations. But little is reported on molar monolithic restoration by IPS e.max Press crown. OBJECTIVE： To evaluate the clinical effects of IPS e.max Press crown on molar repair after root canal therapy. METHODS： Totally 215 patients with 324 affected molars, including 88 males and 127 females, aged 22-58 years old, were enrolled for repairing with IPS e.max Press crown. Then the color, shape, fracture and edge coloring of the restoration, marginal discrepancy, secondary caries and gingival health status were assessed after a 3-year follow-up. RESULTS AND CONCLUSION： During the follow-up, 324 dental restorations met the class A standards for color, marginal discrepancy, shape as well as secondary caries. In addition, 3 restorations were fractured, 14 restorations had margin coloring, and 8 restorations appeared to have gingival inflammation. More than 95% restorations were scored grade A. These results indicate that IPS e.max Press crown applied to molar repair after root canal therapy can achieve ideal outcomes.
