     3) The dentoalveolar characteristics of average angle class II1 malocclusion group showed that: U6 was distal tipping, Ul, L1 was labial inclined, the vertical dentoalveolar height of L6 decreased, the functional occlusal plane (FOP) deviated awayfrom the neutral occlusal axis (NOA), and rotated downward.
     (3)111均角组的牙槽特征主要表现为上领第一磨牙(u6)远中倾斜,上中切牙(Ul)明显前倾,功能赔平面(F OP)偏离自然贻平面(NOA),表现为前下的倾斜(NOA一 FOP交角增大),下切牙(LI)相对于下领平面(MP)前倾。

     Data were obtained to have analysis of variance and LSD mutiple range test. RESULTS: The cranial floor base angle(Ba-SE-FMS)of three groups with class II1 malocclusion was increased. The anterior cranial floor angle was more open in the high angle group, and the flexure of the middle cranial floor was increased in the low angle and average angle groups.
     结果:Ⅱ1错牙合3种骨面型均表现为颅基底角(Ba-SE-FMS)增大,高角组尤其表现在颅前基底角(FMS-SE-PM)增大,均角组、低角组颅中基底角(Ba-SE-PM)增加更为明显。

Objective: To analyse the effects of the treatment of Class II malocclusion by extraoral force. Methods: 12 young patients were treated with head gear extraoral force moving upper first molars distally and then with edgewise appliance.Lateral head cephalograms were taken before and after treatment. Results: Hard and soft tissues both changed in vary degrees.The obvious decrease of ANB angle and inclination of upper central incisor resulted from curbing maxillary and having mandibular growth normally...

Objective: To analyse the effects of the treatment of Class II malocclusion by extraoral force. Methods: 12 young patients were treated with head gear extraoral force moving upper first molars distally and then with edgewise appliance.Lateral head cephalograms were taken before and after treatment. Results: Hard and soft tissues both changed in vary degrees.The obvious decrease of ANB angle and inclination of upper central incisor resulted from curbing maxillary and having mandibular growth normally by extraoral force.The effects were consolidated by edgewise appliance in the second period. Conclusion: Extraoral force conbining edgewise appliance is one of the most simple and effective nonextraction treatments for Class II division 1 malocclusion.

目的 :探讨口外弓推磨牙向后治疗安氏 II类 1分类错牙合的机制。方法 :对 12例安氏 II类 I分类错牙合的少年进行口外弓推磨牙向后治疗 ,第二期用方丝弓矫治器治疗 ;对两期相关的软硬组织进行 X线头影测量。结果 :口外弓推磨牙向后的治疗使颌骨、牙齿、软组织有不同程度的改变 ,主要通过抑制上颌骨 ,使下颌正常生长而使 ANB明显减小 ;口外力也使上中切牙倾斜度明显减小。方丝弓矫治器使治疗更完善。结论 :口外弓推磨牙向后配合方丝弓矫治器是不拔牙治疗安氏 II类 1分类错牙合简便有效的方法之一。

Objective To study the mechanics of Pendulum appliance, and its effects on craniofacial and dentoalvaolar structure Methods 16 class II malocclusion patients (13 females and 3 males)were selected as the subjects, aged from 9 3 to 22 8 years(13 6 on average) All the patients were treated with Pendulum appliance The duration for distolization of upper molars was from 1 to 6 months( 3 7 months on average) Cephalomatric analysis was used Results 1 The upper molar was distalized by 3 59...

Objective To study the mechanics of Pendulum appliance, and its effects on craniofacial and dentoalvaolar structure Methods 16 class II malocclusion patients (13 females and 3 males)were selected as the subjects, aged from 9 3 to 22 8 years(13 6 on average) All the patients were treated with Pendulum appliance The duration for distolization of upper molars was from 1 to 6 months( 3 7 months on average) Cephalomatric analysis was used Results 1 The upper molar was distalized by 3 59 mm per side with mainly tilting movement 2 Incisors moved mesially by 3 28 mm per side (tilting movement) 3 Anterior overjet was increased by 1 56 mm after treatment and more than 6 mm space was created per side 4 The upper molars extruded slightly by 0 69 mm 5 The width of upper arch was increased by 2 03, 1 66, 1 10 mm at molar, premolar and canine region respectively 6 The Pendulum appliance had less effects on craniofacial structure because of short treatment time Conclusions The Pendulum appliance can distalize the upper molars effectively without patients′ active cooperation However, it should be cautions in using the appliance because of its side effects on tilting of molars and mesial movement of incisors

目的 研究改良摆型矫治器对牙和面部骨骼结构的影响。方法 选择安氏Ⅱ类错16例 ,其中女 13例 ,男 3例 ,年龄 9 3~ 2 2 8岁 ,平均 13 6岁。采用摆型磨牙远中移动矫治器治疗。摆型矫治器推磨牙向远中的疗程为 1~ 6个月 ,平均 3 7个月。以X线头影测量分析和模型测量分析为测定手段。结果 ①每侧磨牙平均向远中移动 3 5 9mm ,主要为磨牙向远中倾斜移动。②切牙牙冠平均向近中移动 3 2 8mm ,主要为切牙的近中倾斜移动 ,前牙的覆盖增加 ,达 1 5 6mm。③牙列出现较大的间隙 ,双侧分别达 6 70mm和 6 5 9mm。④磨牙垂直向移动较少 ,推磨牙后 ,磨牙平均伸长仅0 6 9mm。⑤磨牙区、双尖牙区与尖牙区的宽度均增加 ,分别达 2 0 3mm、1 6 6mm和 1 10mm。⑥摆型矫治器对面部骨骼结构无明显的直接影响。结论 摆型矫治器能有效地远中移动上颌磨牙 ,快速矫正磨牙关系。但也可导致磨牙倾斜及切牙唇向倾斜移动 ,临床治疗中应予注意
