【摘要】：目的:探讨改良松牙固定钛链技术固定儿童上颌外伤松牙的临床疗效。方法:选取2013年1月至12月接受治疗的34例牙外伤患儿为研究对象,观察组给予改良松牙固定钛链技术固定松牙,对照组给予弓丝托槽技术进行治疗,比较2组患儿的治疗有效率、牙龈指数、舒适指数、树脂脱落数及操作时间。结果:观察组患儿治疗有效率为94.1%(16/17),对照组为88.2%(15/17),差异无统计学意义(χ2=0.060,P=0.472)。治疗2周后,2组间牙龈指数无明显差异(Z=0.658,P=0.084);治疗4周后,观察组患儿牙龈指数明显低于对照组(Z=2.160,P=0.022)。观察组患儿舒适指数、树脂脱落数及操作时间分别为(3.96±1.27)、(0.11±0.15)、(8.68±1.18)min,对照组分别为(7.34±1.78)、(0.85±0.36)、(19.19±2.85)min,差异有统计学意义(t=3.834、0.056、8.327,P均0.05)。结论:改良松牙固定钛链技术用于固定儿童上颌外伤松动前牙临床疗效可靠,且可减少患儿痛苦,降低牙龈指数,减少树脂脱落数,缩短固定操作时间。
[Abstract]:Objective: to investigate the clinical effect of modified titanium chain fixation for maxillary trauma in children. Methods: 34 children with dental trauma received treatment from January to December 2013 were selected as the study objects. The observation group was treated with modified titanium chain fixation of loose teeth and the control group was treated with arch wire bracket technique. The effective rate, gingival index, comfort index, resin loss and operation time were compared between the two groups. Results: the effective rate of treatment in observation group was 94.1 / 16 / 17, while that in control group was 88.2 / 15 / 17. The difference was not statistically significant (蠂 ~ 2 / 0.060 / P ~ (0.472)). After 2 weeks of treatment, there was no significant difference in gingival index between the two groups. After 4 weeks of treatment, the gingival index in the observation group was significantly lower than that in the control group. The comfort index, resin exfoliation number and operating time were 3.96 卤1.27, 0.11 卤0.15, 8.68 卤1.18 min in the observation group and 0.85 卤0.36 卤2.85 min in the control group, respectively. The difference was statistically significant (P < 0.05). Conclusion: the modified loose teeth fixation technique is effective and reliable in the treatment of children with maxillary trauma, and can reduce the pain, gingival index, resin loss and fixation operation time.
