非手术方法治疗成人反患者软组织疗效分析研究

To research the parenchyma effect by means of nonoperation to treat the patients of adult crossbite

目的:对比非手术方法治疗成人反患者矫治前后软组织的头影测量分析结果,从而确定此种方法的疗效。方法:选用常规拔除前磨牙方法,利用标准方丝弓矫治技术辅以多曲方丝弓技术治疗恒牙期骨性Ⅲ类错畸形患者15例。通过软组织头影测量分析方法,比较治疗前后患者侧貌变化。结果:①软组织改善明显,侧貌更接近正常。②NLA平均减少9.50°,LLL平均减少2.85°,ULP平均增大1.30°,LLP平均减少2.30°,H角平均增大2.10°。③H线与软组织侧面的关系,鼻点-H线(mm)平均减少3.00mm,鼻唇沟-H线(mm)平均增加2.10mm,下唇突点-H线(mm)平均减少1.95mm,颏唇沟-H线(mm)平均增加1.75mm。结论:非手术方法治疗成人反患者,从软组织角度来看,可取得相对满意疗效。

Objective To compare the results of parenchyma cephalometrics analysis before with after orthodontic treatment to ensure the effect when adults crossbite was treated by means of nonoperative treatment. Methods To extract four premolars. Edgewise appliance with MEAW was adopted to treat 15 patients of true skeletal Classlll malocclusion. X-ray Parenchyma Cephalometrics was adopted to compare patients＇ changes of profile before with after the orthodontic treatment. Results （1）The parenchyma changed obviously. The profile is more close to normal state. （2） NLA decreased by 9.50°. LLL decreased by 2.85°, ULP increased by 1.30°; LLP decreased by 2.30°. H Angle increased by 2.10°, （3）The relations of H Line and parenchyma profile ：Nose-H Line （mm） decreased by 3.00mm; Nasolabial groove--H Line （mm） increased by 2.10mm; Labium superius- H Line （mm） decreased by 1.95mm; Mentolabial groove- H Line （mm） increased by 1.75mm. Conclusion To treat adult crossbite by means of nonoperative treatment can obtain satisfying parenchyma effect.
