目的评价FRⅡ型功能性矫治器矫治早期安氏Ⅱ1错畸形的临床效果。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错畸形患儿26例,应用FRⅡ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、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错畸形患者侧貌。
Objective To evaluate the clinical effect of FR Ⅱ functional appliance in the treatment of Angle Ⅱ 1 malformation. Methods From 2005 to 2012, 26 cases of malocclusion of Angle Ⅱ1 malformation in orthodontics department of Stomatology Hospital of China Medical University were selected. Functional FR Ⅱ functional appliance was used for functional correction. The cranial flaps were taken before and after treatment. And use winCeph 8.0 cephalometric software for analysis. Results 26 cases of children correction time of 6 to 14 months, an average of 10.08 months. Correction of the lateral appearance were significantly improved, the relationship between molars reached neutral or near, anterior lamina propria, covering the basic normal.
