| 摘要 目的：研究T4K矫治器治疗替牙早期Ⅱ类错合患儿的临床疗效以及预后。方法：选取从2015年2月到2017年3月在我院接受治疗的48例替牙早期Ⅱ类错合患儿进行研究。采用T4K矫治器治疗患儿6个月，对比患儿治疗前及治疗6个月后的模型测量值、X线头影测量数据以及上面高、下面高、下面高比例，随访3年，分析X线头颅侧位片的检测数据。结果：患儿治疗6个月后的前牙覆合值、前牙覆盖值、上牙弓拥挤度、下牙弓拥挤度均较治疗前明显更低，上牙弓宽度和下牙弓宽度较治疗前明显更高，差异均有统计学意义（均P＜0.05）。治疗6个月后患儿的SNA角、ANB角以及U1-SN角和覆盖均较治疗前明显降低，SNB角、L1-MP角以及U1-L1角和下颌平面角均较治疗前明显升高，差异均有统计学意义（均P＜0.05）。治疗6个月后患儿的上面高、下面高以及下面高比例均较治疗前明显增加，差异均有统计学意义（均P＜0.05）。随访3年显示，ANB角和L1-MP角较治疗6个月后明显降低（P＜0.05），而SNB角、U1-L1角、下颌平面角、上面高、下面高、下面高比例、覆盖均较治疗6个月后明显增高（P＜0.05）。结论：应用T4K矫治器对替牙早期Ⅱ类错合患儿进行治疗的疗效较好，有利于其康复和预后，值得在临床上给予相应的推广。 |

| ABSTRACT Objective: To study the clinical efficacy and prognosis of T4K appliance in the treatment of children with class-Ⅱ malocclusion in early mixed dentition. Methods: A total of 48 children with class-Ⅱ malocclusion in early mixed dentition, who were treated in Shenzhen Hospital of Guangzhou University of Chinese Medicine from February 2015 to March 2017, were selected. The children were treated with T4K appliance for 6 months. The model measured values, X-ray cephalometric data, and above height, below height, below high proportion were compared between the two groups before treatment and 6 months after treatment, followed up for 3 years. The examination data of X-ray cephalometric radiographs were analyzed. Results: The overbite value, overjet value, upper arch crowding, lower arch crowding of children after six months of treatment were significantly lower than those before treatment; the upper arch width and lower arch width were significantly higher than those before treatment, the differences were statistically significant (all P<0.05). SNA angle, ANB angle, U1-SN angle and coverage of children after six months of treatment were significantly lower than those before treatment; SNB angle, L1-MP angle, U1-L1 angle and mandibular plane angle were significantly higher than those before treatment, the differences were statistically significant (all P<0.05). The above height, below height, below high proportion of children 6 months after treatment were significantly higher than before treatment, the differences were statistically significant (all P<0.05). After 3 years of follow-up, the results showed that the ANB angle and L1-MP angle were significantly lower than those 6 months after treatment (P<0.05), while the SNB angle, U1-L1 angle, the mandibular plane angle, above height, below height, below high proportion, coverage were significantly higher than those 6 months after treatment (P<0.05). Conclusion: The application of T4K appliance in the treatment of children with class-Ⅱ malocclusion in early mixed dentition has better curative effect, and it is beneficial to the rehabilitation and prognosis, which is worthy of clinical promotion. |
