目的 :探讨离体粘接加即刻回植治疗后牙纵折的疗效。方法 :选取2013年3月至2015年9月于我院治疗后牙纵折的患者170例,按治疗方式不同分为观察组和对照组,观察组患者行离体粘接加即刻回植治疗法,病例数88例;对照组患者采用传统固定方法进行治疗,病例数82例。观察两组患者的治疗效果,比较两组患者治疗前后咀嚼能力、治疗满意度的差异。结果 :观察组不同性别和不同位置牙纵折的患者治疗有效率均高于对照组,差异具有统计学意义;治疗前,两组不同性别和不同位置牙纵折患者的咀嚼能力均无明显差别,治疗后,观察组不同性别和不同位置牙纵折的患者咀嚼能力均高于对照组;观察组治疗的满意率为97.73%,明显高于对照组(90.24%),差异具有统计学意义。结论 :离体粘接加即刻回植治疗后牙纵折的效果较好,可明显提高患者治疗满意度,具有较高的临床应用价值。 Objective: To investigate the curative effect of tooth longitudinal folding after ex vivo adhesion and immediate replantation. Methods: From March 2013 to September 2015 in our hospital for treatment of posterior teeth fold in patients with 170 cases, according to the different treatment groups were divided into observation group and control group, patients in the observation group were treated with adhesive and immediate replantation Act, the number of cases in 88 cases; control group of patients with traditional fixed method of treatment, the number of cases of 82 cases. The therapeutic effects of two groups of patients were observed, and the differences of masticatory ability and treatment satisfaction between the two groups before and after treatment were compared. Results: The effective rate of treatment in patients with different vertical and longitudinal teeth fracture in the observation group was higher than that in the control group, and the difference was statistically significant. Before the treatment, there was no significant difference in masticatory ability between the two groups After treatment, the masticatory abilities of the patients in the observation group with different longitudinal and longitudinal teeth were higher than those in the control group. The satisfaction rate of the observation group was 97.73%, which was significantly higher than that of the control group (90.24%). The difference was statistically significant. Conclusion: The effect of tooth longitudinal folding after ex vivo adhesive plus immediate replantation is better, which can significantly improve the patient satisfaction and has high clinical value.
