Abstract

Objectives

The aim of this study was to evaluate the efficacy of functional orthopedic therapy in growing patients whose facial profiles can be esthetically improved by moving the mandible forward.

Materials and methods

We conducted a controlled longitudinal cohort study of children with receding chins, normodivergent cephalometric profiles, and class II molar relations with an overjet of >5 mm. Ten of the patients (five boys with a mean age of 11.5 years [SD±1.5] and five females with a mean age of 10.5 years [SD±1.5]) were treated with bite jumping and ten served as age- and sex-matched controls. Results were evaluated in terms of esthetic parameters and changes in 11 cephalometric angle measurements. Statistical analysis was based on Student's t test; p values <0.05 were considered significant.

Results and Conclusions

The treated patients present clear esthetic improvement in the facial profile with statistically significant changes in dental, alveolar, and maxillary protrusion, but no significant effects on the mandible.

下颌关节功能骨科治疗:一种理论和实践方法

目的本研究的目的是评估功能性矫形治疗在通过下颌骨向前移动来改善面部轮廓的成长期患者中的疗效。材料和方法我们进行了一项对照纵向队列研究，研究对象为下颌后缩、头侧轮廓正常、II类磨牙关系覆盖5mm的儿童。10例患者(5例男孩，平均年龄11.5岁[SD±1.5]，5例女性，平均年龄10.5岁[SD±1.5])进行咬跳治疗，10例作为年龄和性别匹配的对照组。根据美观参数和11个头角测量值的变化来评估结果。统计分析采用Student’st检验;P值<0.05认为显著。结果与结论治疗后患者的面部轮廓明显改善，牙、牙槽和上颌前突的变化有统计学意义，而下颌骨的变化无统计学意义。
