摘　　要：目的：探讨IPS e.max Press铸瓷髓腔固位冠在个别上前牙错位修复中的临床疗效。方法选择15例个别上前牙错位的患者,经完善根管治疗和（或）牙周治疗,1~2周后制作IPS e.max Press铸瓷髓腔固位冠,树脂粘接剂粘固。并于6个月、1年后复查修复体的颜色、形态、边缘密合性、牙龈健康情况、基牙及修复体的保存情况。结果1年内所有修复体边缘密合、牙龈健康、颜色美观；除1例基牙移位外,其余髓腔固位冠无松动移位。保存率100%（15/15）,临床可接受率为93.3%（14/15）。结论 IPS e.max Press铸瓷髓腔固位冠用于个别上前牙错位的修复可取得良好的效果。Objective The present study aimed to evaluate the clinical effects of IPS e.max Press ceramic endocrowns applied in individual maxillary anterior teeth malposition. Methods Fifteen malposed maxillary anterior teeth were selected from fifteen patients in this study. All the malposed teeth had been endodontically treated and performed with ultrasonic scaling. After 1-2 weeks, the IPS e.max Press ceramic endocrowns were fabricated and cemented with resin cement. The color, shape, margin fitness, preservation of the restorations and the gingival health of the abutments were reviewed after 6 months and 12 months respectively. Results The margins of all restorations were well sealed; the colorsand shapes of the restorations were satisfied and matched with the natural teeth; and the periodontal tissues of the abutments were healthy. Except for one case with displacement of the abutment, the remaining endocrowns were functioning well without loosening. The preservation rate of the restorations was 100%（15/15）, and the clinically acceptable rate was 93.3%（14/15）. Conclusions Application of IPS e.max Press ceramic endocrowns in repairing individual maxillary anterior teeth malposition could obtain satisfied effects.
