    摘要:

    目的:评价比较IPS e. max Press铸瓷全冠-贵金属烤瓷全冠-镍铬合金烤瓷全冠的临床修复效果-方法:选择IPS e. max Press铸瓷全冠-贵金属烤瓷全冠-镍铬合金烤瓷全冠等3种材料修复上中切牙的患者各90例,参照美国公共卫生服务的相关标准对完成修复后即刻与12个月的修复体进行临床检查和相关评价,内容包括修复体颜色-牙龈边缘着色-继发龋-边缘密合度-牙龈健康状况等-结果:在修复体颜色与牙龈健康状况方面,IPS e. max Press铸瓷全冠与贵金属烤瓷全冠均显著优于镍铬合金烤瓷全冠(P < 0.05);在牙龈边缘着色和边缘密合度方面,IPS e. max Press铸瓷全冠-贵金属烤瓷全冠与镍铬合金烤瓷全冠均存在显著性差异(P < 0.05),IPS e. max Press铸瓷全冠最佳,贵金属烤瓷全冠次之;3组修复体均未发生继发龋-结论:IPS e. max Press铸瓷全冠修复的临床效果优良,贵金属烤瓷全冠次之,均优于镍铬合金烤瓷全冠-

    Abstract:

    Objective:To observe the clinical outcome of IPS e. max Press all-ceramic crown,gold alloy porcelain fused metal (PFM) crown and Ni-Cr alloy PFM crown restorations. Methods:Three groups of patients were treated with IPS e. max Press all-ceramic crown,gold alloy PFM crown or Ni-Cr alloy PFM crown restorations separately. The crown restorations were evaluated with the USPHS criteria for color match,marginal discoloration,secondary caries,marginal adaptation and gingival health immediately and after a period of 12 months. Results:The clinical outcome of both IPS e. max Press all-ceramic crown and gold alloy PFM crown restorations was better than Ni-Cr alloy PFM crown restorations for color match and gingival health. There was statistically significant difference in 3 groups for marginal discoloration and marginal adaptation,in which IPS e. max Press all-ceramic crown restoration was the best and gold alloy PFM crown restoration was better than Ni-Cr alloy PFM. No secondary caries was detected. Conclusion:IPS e. max Press crown restoration exhibits excellent clinical outcome over a period of 12 months,and gold alloy PFM crown restoration is better than Ni-Cr alloy PFM.
