| 摘要 目的：对比不同治疗方法对中青年残根残冠患者咀嚼功能及舒适度的影响。方法：2018年8月到2020年7月选择在本院进行前牙美容修复的中青年残根残冠患者82例，根据随机信封抽签原则将患者分为观察组40例与对照组42例。对照组给予牙冠延长术治疗，观察组给予纤维桩加全瓷冠修复治疗，记录与随访患者预后情况。结果：两组修复后3个月的舌向集中??侧向??与前伸??最大应力值小于解剖??（P<0.05），解剖??的正中??少于侧向??与前伸??（P<0.05），组间对比差异无统计学意义（P>0.05）。观察组修复后3个月的咬合接触时间多于对照组（P<0.05），左右侧??力百分比、??力中心距离少于对照组（P<0.05）。观察组修复后3个月的成功率为97.5 %，高于对照组的85.7吧%（P<0.05）。观察组修复后3个月的外观效果与舒适水平评分均高于对照组（P<0.05）。随访12个月，观察组的牙龈萎缩、感染、松动等并发症发生率为2.5 %，低于对照组的19.0 %（P<0.05）。结论：相对于牙冠延长术，纤维桩加全瓷冠在前牙残根残冠修复中的应用能提高患者的咀嚼功能与舒适度，并不会影响光弹性状况，从而提高修复效果，减少随访并发症的发生。 |

| ABSTRACT Objective: To compare the effects of different treatment methods on masticatory function and comfort of young and middle-aged patients with residual roots and crowns. Methods: From August 2018 to July 2020, 82 cases of young and middle-aged patients with residual roots and crowns who were selected for cosmetic restoration of anterior teeth in this hospital were selected and were equally divided into observation group of 40 cases and control group of 42 cases accorded to the principle of random envelope drawing. The control group were given crown lengthening treatment, and the observation group were given fiber post plus all-ceramic crown restoration treatment. The prognosis of the patients were recorded and followed up. Results: The tongue concentration (lateral) and extension of the two groups of tongues were less than the anatomical occlusion (P<0.05) at 3 months after repair. The median of the anatomical occlusion were less than the lateral occlusion and the extension (P<0.05), there were no statistically significant difference compared between the groups (P>0.05). The occlusion contact time of the observation group at 3 months after repair were longer than that of the control group (P<0.05), and the percentage of force on the left and right sides and the distance between the center of force in the observation group were less than those of the control group (P<0.05). The success rates of the observation group at 3 months after repair were 97.5 %, which were higher than 85.7 % of the control group (P<0.05). The appearance effect and comfort level scores of the observation group at 3 months after repairwere higher than those of the control group (P<0.05). Followed-up for 12 months, the incidence of gingival recession, infection, loosening and other complications in the observation group were 2.5 %, lower than 19.0 % in the control group (P<0.05). Conclusion: Compares with crown lengthening surgery, fiber post plus full The application of porcelain crowns in the restoration of residual roots and crowns of anterior teeth can improve the patient's masticatory function and comfort without affecting the photoelasticity, thereby improving the effect of repair and reducing the occurrence of follow-up complications. |
