摘　　要：目的评估比较热压铸瓷二代(IPS-Empress)修复体和肩台瓷(IPS-Margin)金瓷修复体颈缘的临床效果。方法临床为63例患者的90颗患牙进行IPS-Empress热压铸陶瓷全冠修复,为98例患者的129颗患牙进行有肩台瓷的PFM全冠修复。永久性粘结后6个月和36个月复诊,比较修复体颈缘临床效果。结果在比较后发现铸瓷全冠和肩台瓷在牙龈变色,颈缘适合度,牙龈炎症三方面均无显著性差异。结论肩台瓷修复体与全瓷修复体能达到相同的颈缘效果。对想解决颈缘问题又无力支付全瓷冠的修复患者来说,肩台瓷不失为一种好的选择。Objective To evaluate and compare the cervical margin fitness and gingival discoloration between IPS - EMPRESS Ⅱ all ceramic crown and PFM crown with shoulder ceramic margin. Methods Ninty teeth of 63 patients were restored with IPS -EMPRESS Ⅱ pressable ceramic crowns and 129 teeth of 98 patients were restored with PFM crowns with shoulder ceramic margins. The marginal fitness, gingival discoloration, and gingival health of all these restorations were examined at 6 months, and 36 months after permanent luting respectively. Results There was no statistical difference for gingival discoloration, marginal fitness and gingival health between IPS - Empress Ⅱ and PFM crown with shoulder ceramic margin （ P 〉 0.05）. Conclusion Both PFM crown with shoulder ceramic margin and IPS - Empress Ⅱ ceramic crown satisfied the esthetic demand in the cervicM margin area. PFM crown with shoulder ceramic margin is a reliable and ideal choice for the low - budget patients with the desire of esthetic cervical margin.
