| [摘要] 目的 评价CEREC 3D系统制作的全瓷嵌体与钴铬合金嵌体在牙体修复的临床效果。 方法 选取根管治疗后II类洞无髓牙90颗，根据患者对材料的选择，一组采用CEREC 3D系统制作瓷嵌体48颗，一组制作钴铬合金嵌体42颗。修复后定期复查追踪观察2年，观察临床效果。 结果 按照改良的USPHS标准进行临床评价，两组在2年后复查，在边缘密合性、外形、牙体完整性方面差异有显著性意义(P<0.05)，在牙龈健康状况上差异无显著性意义(P>0.05)。 结论 CEREC 3D制作瓷嵌体在牙体修复中具有优良的临床效果，明显优于钴铬合金嵌体。 |

| Abstract: |
| [Abstract] Objective To evaluate clinical effects of ceramic inlays fabricated by the Cerec III CAD/CAM system and Co-Cr alloy inlays in restorating posterior teeth. Methods 90 cases after root canal therapy were selected. One group included 48 cases with Ceramic inlays by the Cerec Ⅲ CAD/CAM; the other group included 42 cases with Co-Cr alloy inlays. We examined clinical effects after two years restoration. Results Statistically significant difference was shown in marginal fit, appearance, and integrity of the tooth after 2 years restoration. Conclusion Ceramic inlays by CEREC Ⅲ CAD/CAM system have better clinical effect than Co-Cr alloy inlays. |
