摘要
目的探讨临床应用改良固定反式双阻板矫治器（twin-block appliance，TBA）联合方丝弓技术治疗成人AngleIH类前牙反[牙合]的临床应用效果。方法应用改良固定反式TBA联合方丝弓技术矫治成人前牙反[牙合]18例，对治疗前后临床表现及X线软组织测量进行分析，评价其临床矫治效果。结果下颌软组织的变化十分明显，较快改善了侧貌外形。上颌前牙适度的唇倾也对软组织侧貌改善起了一定的作用。随访病例最长的3年，无复发。结论改良固定反式TBA联合方丝弓技术，可快速有效矫治成人前牙反[牙合]，对下颌软组织的影响较大。
Objective To evaluate the curative effects of the modified fixed reverse Twin-block appliance （TBA）combined Edgewise in the treatment of adult Angle Ⅲ anterior crossbite. Methods The appliance was used in 18 subjects with adult Angle Ⅲ skeletal malocclusion and clinical characters and X- ray cephalometry were then compared before and after treatment. Results The mandibular soft tissue changes could be achieved fast and the profile bad changed effectively. Moderate labioelination of maxillary anterior teeth played a role in the improvement of axillary soft tissue protrusion. The cases were followed up as long as 3 years. No relapse occurred in all the patients. Anterior occlusion was normal. Conclusion All findings indicate that adult Angle Ⅲ anterior crossbite can be quickly corrected with the modified fixed reverse TBA combined Edgewise. The effect on mandibular soft tissue is significant.
