摘要
目的运用支架式快速扩弓器进行前方牵引,评价其软硬组织发生的变化。方法 15例替牙期患儿,年龄9～11岁,先进行快速扩弓1～2周,然后行前方牵引,治疗前、后摄头颅定位侧位片并进行头影测量分析。结果快速扩弓后进行前牵引治疗前、后结果差异有显著性,上颌骨及上牙弓均前移,软组织侧貌明显改善。结论在替牙期前方牵引联合快速扩弓治疗早期骨性Ⅲ类错可获得较多的骨骼变化,侧貌改善明显。
Objective To appraise effects of the maxillary protraction and rapid palatal expansion（RPE） on the soft and hard tissues.Methods Fifteen patients in their mixed dentition（from 9 to 11 years old）were selected.Patient were treated with rapid palatal expansion for 1-2 weeks before maxillary protraction.Lateral cephalometric radiographs were used to measure the changes of soft and hard tissue changes before and after treatment.Results After maxillary protraction and rapid palatal expansion treatment,the effects were significant.The maxilla and upper dentitions were protracted and obvious profile changes could be observed.Conclusions It is an effective method to manage premature class Ⅲ malocclusion with RPE and maxillary protraction therapy,which can acquire more obvious skeleton and profile changes.
