| 摘要 目的：探究氧化锆强化硅酸锂玻璃陶瓷与Lava UItimate优韧瓷嵌体修复根管治疗后大面积缺损牙的咀嚼能力和外观的效果。方法：选择298例牙缺损患者随机分为观察组和对照组2组，其中观察组患者给与Lava UItimate优韧瓷嵌体修复治疗，对照组给与氧化锆强化硅酸锂玻璃陶瓷嵌体修复治疗。对比分析两组患者修复效果、咀嚼能力、外观变化、牙龈指数和菌斑指数、修复满意度以及并发症发生率。结果：观察组患者修复的完整度为99.33 %，颜色匹配度为97.32 %，边缘适合性为98.66 %，均显著高于对照组的77.18 %、65.77 %和67.11 %（P<0.05）。修复后，观察组患者的咀嚼能力、外观变化显著优于对照组（P<0.05），PLI和GI显著低于对照组（P<0.05）。并且，观察组患者对修复的总满意度为99.33 %，显著高于对照组的82.55 %（P<0.05），并发症发生率为2.01 %，显著低于对照组的29.53 %（P<0.05）。结论：Lava UItimate优韧瓷嵌体修复根管治疗后大面积缺损牙的咀嚼能力和外观的效果较氧化锆强化硅酸锂玻璃陶瓷好，可显著降低并发症发生率，提高患者满意度，值得临床推广使用。 |

| ABSTRACT Objective: To explore the effect of zirconia reinforced lithium silicate glass ceramics and Lava UItimate ceramic inlays on the masticatory ability and appearance of large-area defective teeth after root canal treatment. Methods: A total of 298 patients with dental defects were selected and randomly divided into two groups: the observation group and the control group. The patients in the observation group were treated with Lava UItimate ceramic inlays, and the control group was treated with zirconia-enhanced lithium silicate glass-ceramic inlays. The repair effect, chewing ability, appearance change, gingival index and plaque index, repair satisfaction and complication rate were compared between the two groups. Results: The restoration integrity, color matching and edge fitness in observation group were 99.33 %, 97.32 % and 98.66 %, respectively, which were higher than 77.18 %, 65.77 % and 67.11 % in control group (P<0.05). After repair, chewing ability and appearance changes in observation group were better than control group (P<0.05), PLI and GI were significantly lower than control group (P<0.05). In addition, the total satisfaction of patients in the observation group was 99.33 %, higher than that in the control group (82.55 %) (P<0.05), and the complication rate was 2.01 %, lower than that in the control group (29.53 %) (P<0.05). Conclusion: Compared with zirconia reinforced lithium silicate glass ceramic, Lava UItimate has better chewing ability and appearance in the restoration of large defect teeth after root canal treatment, which can significantly reduce the incidence of complications and improve patient satisfaction. Therefore, it is worthy of clinical application. |
