摘要:

目的探讨IPS- Empress 2热压铸陶瓷全冠的修复效果。方法对70例患者的198颗牙进行IPS- Empress 2热压铸陶瓷全冠修复,修复后1周及每半年复诊1次,对其临床效果进行评价。结果经过3~38个月的随访,全冠修复的198颗牙中,3颗牙发生饰面瓷崩瓷,2颗牙因基牙冠折致全冠脱落,2颗牙的牙龈出现红肿,3颗牙发生牙髓炎或根尖周炎,3颗牙的全冠色泽变暗。余185颗牙修复效果满意,满意率为93.4%。结论IPS- Empress 2热压铸陶瓷冠具有美观、生物相容性好、制作相对简单的优点,但同时也具有强度不够高、遮色效果差的缺点。

Abstract:

Objective To evaluate the clinical prosthetic effect of IPS- Empress 2 pressable ceramic crowns. Methods 198 teeth of 70 patients were restored with IPS- Empress 2 pressable ceramic crowns. The patients were asked to return in one week and every half year. The clinical prosthetic effect was evaluated. Results Through follow- up of 3- 38 months, the veneer porcelain crowns of 3 teeth were broken. 2 crowns fall off due to teeth fracture, gingivitis occurred in 2 teeth, pulpitis or periapical periodontitis occurred in 3 teeth. The shades of 3 crowns were darkening. The prosthetic effect of 185 teeth was satisfied. The rate of satisfaction was 93.4%. Conclusion IPSEmpress 2 pressable all- ceramic crown has the advantages of aesthetic effect, good biocompatibility and simple fabrication. But its strength is not enough for posterior teeth and it can not cover the deep color of non- vital teeth and metal materials.
