目的 评价方丝弓矫治和Twin -block功能矫治对骨性Ⅱ1错牙合非拔牙患者颌骨的影响。方法 选择 30例 11~ 14岁的骨性Ⅱ1错牙合患者 ,随机分为 2组 ,E组用方丝弓配合Ⅱ类牵引治疗 ,T组用Twin -block功能矫治。对治疗前后的X线头影测量数据进行统计学分析。结果与结论 方丝弓固定矫治配合Ⅱ类牵引可改变牙合的Ⅱ类关系 ,下颌骨长度及骨面突度改变较少。功能矫治器有效促进了下颌骨生长 ,使长度增加位置前移。

【Objective】To evaluate the dento-alveolar, skeletal and soft tissue changes caused by Class Ⅱ division 1 malocclusion correction in the patients treated with Twin-block appliance.【Methods】Sixteen patients in growth with Angle Class Ⅱ division 1 malocclusion and mainly with mandibular retrognathia were investigated.Lateral cephalometric X-ray was taken, and skeletal, dento-alveolar and soft tissure measurements were carried outbefore and after treatment for each patient.

【Objective】To evaluate the dento-alveolar, skeletal and soft tissue changes caused by Class Ⅱ division 1 malocclusion correction in the patients treated with Twin-block appliance.【Methods】Sixteen patients in growth with Angle Class Ⅱ division 1 malocclusion and mainly with mandibular retrognathia were investigated.Lateral cephalometric X-ray was taken, and skeletal, dento-alveolar and soft tissure measurements were carried outbefore and after treatment for each patient. Two time-points of results were compared and submitted to statisticalanalysis.【Results】Changes were occurred for the growth direction and length of mandible after treatment. Overjetand overbite were decreased by 8.13 mm and 4.27 mm, respectively, while SNB, mandibular plane angle, Ar-Pogand lower facial height were increased by 1.70°and 3.47°, 4.06 mm and 2.53 mm, respectively. The maxillaryincisors has a tendency of lingual torque (P >0.05), without advancement of point A, which contributes to anincreased degree of nasal-labial angle and decreased protrusion of upper lip (P< 0.01). In addition, the inclinationof lower incisors decreased slightly, although with no statistical significance, it was important to evaluate the stabilityof the lower anterior segment after treatment. 【Conclusions】 Twin-block functional appliance possesses theorthopedic effect on Angle Class Ⅱ division 1 malocclusion. When repositioning the mandible forward, it creates the force to limit maxillary growth forward as well. Simultaneously it causes the changes of dento-alveolar. All the seaspects contribute to a harmonious relationship of upper and lower jaws and a better profile.

【目的】探讨Twin-block功能矫治器治疗安氏Ⅱ类1分类错牙合所引起的牙、牙槽、颌骨以及软组织的改变。【方法】对16例处于生长发育期且以下颌后缩为主的安氏Ⅱ类1分类错牙合患者进行Twin-block功能矫治,并对其治疗前后软硬组织X线头影测量值进行比较及统计学检验。【结果】治疗后,下颌生长朝着有利的方向发生改变,覆盖、覆牙合分别减少8.13mm及4.27mm,SNB、下颌平面角、Ar-Pog及下面高分别增加1.70°、3.47°、4.06mm及2.53mm,均具有显著性差异。此外,上颌前牙冠有舌向转矩的趋势(P>0.05),鼻唇角有所增加,上唇突度亦减小(P<0.01)。下切牙与下颌平面夹角有少许减小,虽无显著性差异,但对于评价治疗后的下前牙段的稳定性是有意义的。【结论】Twin-block矫治器对安氏Ⅱ类1分类具有矫形作用,可以诱导下颌功能性前移,抑制上颌生长,同时使得上下颌牙及牙槽骨发生改变,从而协调上下颌关系,改善面型。

目的在生长发育高峰期观察不同矫治方法对骨性Ⅱ1分类错牙合患者软组织侧貌的影响。方法选择骨性Ⅱ1分类错牙合非拔牙儿童30例,随机分为2组,E组用方丝弓配合Ⅱ类牵引治疗16个月,T组用Twin-block功能矫治,治疗及观察16个月,以X线头影测量分析方法评价疗效。结果功能矫治组的软组织侧貌有明显改善,而固定矫治组改变不明显。结论功能矫治可获得良好的侧貌改善,但长期效果有待于进一步观察。
