Sirona Cerec 3D全瓷冠与金属烤瓷冠修复前牙的临床对比

Clinical therapeutic effect comparison between Sirona Cerec 3D all-ceramic crowns and porcelain fused to metal crown in anterior teeth restoration

目的评价Sirona Cerec 3D全瓷冠进行前牙修复的临床效果。方法将81例（145颗前牙）患者进行随机分组，参照美国加利福尼亚牙科协会（CDA）评价标准，对使用1年的牙冠进行评价，并与同期治疗的金属烤瓷冠进行对比。结果SironaCerec3D全瓷冠修复组在边缘完整性、解剖外形、颜色和表面的成功率分别为97．5％、95％、100％、97．5％，而金属烤瓷冠对照组成功率为97．6％、92．6％、87．8％和95．1％。修复组在解剖外形和颜色方面明显优于对照组（P〈0．05），且牙龈炎等副反应发生率小。结论SironaCerec3D全瓷冠进行前牙修复效果良好，值得临床广泛推广。

Objective To evaluate the clinical therapeutic effect ofSirona Cerec 3D all-ceramic crowns in anterior teeth restoration. Methods 81 patients（145 anterior teeth） were divided randomly into two groups. The clinical evaluation criteria of CDA was performed 6 months to two years after wearing. And we compared the effects with porcelain fused to metal （PFM） crowns in the same period. Results On the integrity of crown margin, anatomical shape, color and surface, the succeed rate of all-ceramic crowns group were 97.5%,95%,100% and 97.5% respectively while PFM crowns group were 97.6%,92.6%,87.8% and 95.1% respectively. All-ceramic crowns group was better than PFM crowns group on the anatomical shape and color （ P 〈 0.05 ） and had less side effects.Conclusion Sirona Cerec 3D all-ceramic crowns has a good effect in anterior teeth restoration, worthy in expanded clinical use.
