Abstract

OBJECTIVE To evaluate the anchorage control and distalization of maxillary molars with the hybrid Pendulum appliance and to compare the results with a conventional Pendulum appliance. MATERIALS AND METHODS This study was carried out on the pre-(T0) and post-(T1) treatment lateral cephalograms and dental casts of 43 patients with Angle Class II molar relationships who were treated with conventional or hybrid Pendulum appliances. The hybrid Pendulum (HP) group consisted of 22 patients (14 females; eight males; mean age 14.3 ± 2.43 years) and treatment results were compared with a conventional Pendulum appliance (CP) group, which consisted of 21 patients (15 females; six males; mean age 14.6 ± 3.39 years). Intragroup comparisons were made with Wilcoxon test and intergroup comparisons were made with Mann-Whitney U-test (P < .05). RESULTS The mean distalization duration was 0.70 ± 0.25 years in the HP group and 0.83 ± 0.4 years in the CP group. Maxillary first molars showed significant distal movement and tipping of 4.25 mm and 9.09° in the HP group, and 3.21 mm and 9.86° in the CP group. Loss of anchorage at the first premolars was significantly smaller in the HP appliance group compared to CP group. The second premolars distalized spontaneously in the HP group while they mesialized significantly in the CP group. Proclination and protrusion of maxillary incisors were greater with the CP appliance compared to the HP appliance. CONCLUSIONS Maxillary molar distalization was achieved with both appliances. Mesialization of the anchorage unit was controlled successfully with the hybrid Pendulum; however, the conventional Pendulum appliance caused anchorage loss.

比较混合摆与传统摆器的效果。
目的评价混合式钟摆矫治器对上颌磨牙的支抗控制和离体效果,并与常规钟摆矫治器进行比较。材料与方法本研究对43例采用常规或混合式摆治器治疗的Angle II类磨牙关系患者进行治疗前(T0)和治疗后(T1)的侧位头颅造影和牙模分析。混合型摆(HP)组22例,其中女性14例;八个男性;平均年龄(14.3±2.43)岁)与常规钟摆矫治器(CP)组21例(女性15例;六个男性;平均年龄14.6±3.39岁)。组内比较采用Wilcoxon检验,组间比较采用Mann-Whitney u检验(P < 0.05)。结果HP组和CP组的平均离体时间分别为0.70±0.25年和0.83±0.4年。上颌第一磨牙远端移动明显,HP组为4.25 mm、9.09°,CP组为3.21 mm、9.86°。HP矫治组第一前磨牙支抗损失明显小于CP组。HP组第二前磨牙自发离体,而CP组第二前磨牙明显离体。与HP矫治器相比,CP矫治器上颌门牙的前倾和前伸更大。结论两种矫治器均能达到上颌磨牙远端。采用混合摆控制了锚固单元的定位;然而,传统的钟摆矫治器造成了锚固损失。
