【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。
[Abstract]:Background: e.max Press casting porcelain has excellent biocompatibility and corrosion resistance. It has been applied to the restoration of anterior tooth veneer, premolar inlay and high inlay, but it is rarely used in monocoronal restoration of molars. Objective: to evaluate the clinical effect of IPS e.max Press cast porcelain crown in the restoration of molars after root canal therapy. Methods: two hundred and fifteen patients (including 88 males and 127 females, aged 22-58 years) were enrolled in the study. All of them were treated with IPS e.max Press cast porcelain full crown for molar restoration. After 3 years follow-up, the color, shape, fracture and edge of the restoration were evaluated. Marginal tightness, abutment secondary caries and gingival health. Results and conclusion: during 3 years follow-up, 324 prostheses were found to be in color, shape, and edge tightness. The secondary caries of abutment teeth were all up to the A grade standard. All of the 14 prostheses with creased restoration edge were stained with gingival inflammation and more than 95% of the prostheses were grade A. The results showed that the failure rate of IPS e.max Press cast porcelain full crown for the restoration of molars after root canal therapy was low and the clinical effect was good.
