摘要:

目的 评价FR Ⅱ型功能性矫治器矫治早期安氏Ⅱ1错牙合畸形的临床效果。方法 选择2005—2012年在中国医科大学口腔医学院正畸科就诊的安氏Ⅱ1错牙合畸形患儿26例,应用FR Ⅱ型功能性矫治器进行功能性矫治,在治疗前后拍摄头颅侧位片,并用winCeph 8.0头影测量软件进行分析。结果 26例患儿矫治时间6~14个月,平均10.08个月。矫治后侧貌均得到明显改善,磨牙关系达中性或偏近中,前牙覆牙合、覆盖基本正常。结论 FRⅡ型功能性矫治器可促进下颌生长,同时刺激上、下颌牙齿及牙槽骨发生有利的改变,从而协调上、下颌关系,改善安氏Ⅱ1错牙合畸形患者侧貌。

Abstract:

Abstract:Objective To investigate the clinical effect of function regulatorⅡ (FRⅡ) appliances in the treatment of skeletal Class Ⅱ1 malocclusion. Methods Totally 26 child patients with skeletal Class Ⅱ1 malocclusion were treated with FR Ⅱ appliances. Cephalometric radiographs were taken and analyzed at pre-treatment and post-treatment. Paired T-test was used to determine if there were significant differences by SPSS 13.0. Results After a treatment by FRⅡ,the growth of the mandible was stimulated. Overbite,overjet,ANB(°) and lip protrusion decreased significantly(P < 0.05),while SNB(°) and L1-MP(°) increased significantly(P < 0.05). Conclusion FRⅡ appliances is fit for the early orthodontic treatment of skeletal ClassⅡ1 malocclusion. A harmonious relationship between upper and lower jaws and a better profile can be obtained.
