目的:研究正畸带环与树脂临时冠对牙隐裂暂时性保护的临床疗效,为临床治疗提供依据。方法:选取2013年5月到2015年4月我院收治的牙隐裂患者196例,按照随机数字表法将患者分为A组和B组,每组98例,A组给予正畸带环治疗,B组给予树脂临时冠治疗,比较两组固定效果、咬合情况、牙周情况以及满意度。结果:两组固定成功率比较无统计学意义(P>0.05);A组牙龈炎发生率为12.2%显著高于B组的3.1%,差异具有统计学意义(P<0.05);B组满意度为95.9%显著显著高于A组的80.6%,差异具有统计学意义(P<0.05)。结论:树脂临时冠较正畸带环对牙隐裂暂时性保护作用较好,患者满意率较高,值得临床推广应用。
Objective: To study the clinical curative effect of temporary protection of orthodontic band ring and resin temporary crown on occlusion of the tooth, providing the basis for clinical treatment. Methods: A total of 196 patients with occlusion of the tooth in our hospital from May 2013 to April 2015 were selected. Patients were divided into group A and group B according to the random number table method, with 98 cases in each group. Group A was given orthodontic band Treatment, Group B was given temporary resin crown treatment, the two groups were compared fixed effect, occlusion, periodontal condition and satisfaction. Results: There was no significant difference between the two groups in the success rate of fixation (P> 0.05). The incidence of gingivitis in group A was significantly higher than that in group B (12.2% vs 3.1%, P <0.05) The degree of 95.9% was significantly higher than 80.6% in group A, the difference was statistically significant (P <0.05). CONCLUSION: The temporary resin crown is better than the orthodontic band in the temporary protection of occlusion. The satisfactory rate of patients is high, which is worthy of clinical application.
