目的比较FR-Ⅲ型功能调节器和前方牵引在安氏Ⅲ类错牙合畸形中的应用效果。方法选取2015年3月~2016年3月在我院治疗的安氏Ⅲ类错牙合畸形患者48例,根据治疗方法的不同,分为A、B组两组,各24例,A组患者给予FR-Ⅲ型功能调节器治疗,B组患者给予前方牵引治疗,比较两组患者矫治效果和前牙覆盖情况的改善。结果经治疗,全部患者的矫治效果都是比较满意的,在经过矫治之后,全部患者都达到了Ⅰ类的磨牙关系,并且凹面形也发生了较好的改变,于前牙覆盖的改善基础上,B组改善的状况显著的要比A组好;在磨牙的关系的改善方面上,A组的效果要显著的好于B组,经比较,差异有统计学意义(P<0.05)。结论为了获得理想的矫治效果,在对安氏Ⅲ类错牙合畸形患者进行牙齿矫治的过程中,要和患者的发病机制与发病因素进行较好的结合考虑,采取科学、合理的矫正计划,从而使患者的身体健康和生活质量获得优化和改善。
Objective To compare the effect of FR-Ⅲ functional regulator and anterior traction in Class Ⅲ malocclusion. Methods Forty-eight patients with Class III malocclusion treated in our hospital from March 2015 to March 2016 were divided into two groups according to the different treatment methods: group A and group B, 24 cases each, group A The patients were given FR-Ⅲ functional modifier treatment, the patients in group B were given traction therapy, and the treatment effect and the coverage of anterior teeth in both groups were compared. Results After treatment, the treatment effect was satisfactory in all patients. After correction, all the patients achieved type Ⅰ molars relationship, and the concave shape also had a good change. Based on the improvement of anterior teeth coverage , The improvement of group B was significantly better than that of group A. The effect of group A was significantly better than that of group B in improving the relationship of molars, the difference was statistically significant (P <0.05). Conclusion In order to obtain the ideal effect of orthodontic treatment, in the process of orthodontic treatment for Class III malocclusion patients, we should combine with the pathogenesis and risk factors of patients and take a reasonable and reasonable correction plan, So that the patient’s health and quality of life are optimized and improved.
