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: The IPS e.max Press cast ceramic possesses excellent biocompatibility and corrosion resistance. It has achieved good clinical results in the application of anterior veneers, premolar inlays and inlays, but it has been applied to Research on molar single crown repair is rare. OBJECTIVE: To evaluate the clinical effect of IPS e.max Press porcelain crown applied to the restoration of molars after root canal therapy. METHODS: A total of 215 patients (324 affected teeth) were enrolled, including 88 males and 127 females, aged 22-58 years. All patients underwent eyelid crown restoration with IPS e.max Press, and were followed up for 3 years. Restoration of color, shape, fracture, edge coloring, edge adhesion, abutment secondary caries and gum health. RESULTS AND CONCLUSION: A total of 324 prostheses reached Grade A standard in terms of color, morphology, margin adhesion and secondary caries of abutments within 3 years of follow-up. Three prostheses were fractured, 14 prostheses were edge-stained and 8 prostheses Gingival inflammation, more than 95% of the prosthesis reached A level. The results showed that the failure rate of molar restoration after root canal treatment with IPS e.max Press cast crown was lower and the effect of clinical repair was good.
