提高和评价口外牵引正畸治疗 类骨面型错畸形的临床效果。方法 :采用作者自己设计的口外牵引装置 ,联合应用口内方丝弓矫治器及附加腭弓和前腭板 ,对上颌骨进行整体前方牵引。结果 :本组反均得到解除 , 类凹面型正侧位观基本已过渡到正常或比较令人满意的 类面型。磨牙关系矫治前完全近中 2 4例中 16例矫治后成为中性关系 ,8例轻度近中及 32例开始近中错 ,矫治后均为中性关系。结论 : 类口外牵引正畸治疗骨面型错效果明显而肯定 ,对上后缩畸形矫治 ,即使是生长发育快速期接近完成 ,通过口外重力和坚持较长时间牵引 ,也同样收到满意效果。
To improve and evaluate the clinical effect of oral traction orthodontic treatment of osteopontal malocclusion. Methods: The authors designed their own extraoral traction device, combined with the application of the oral arch appliance and the additional palatal arch and the anterior palatal plate, the entire front of the mandibular traction. Results: All cases were relieved of anti , the concave side of the positive lateral view has basically transition to normal or more satisfactory quasi-type. Molar relationship between the treatment before the complete correction of Zhong Zhong 2 4 cases, 16 cases after correction of a neutral relationship, 8 cases of mild near-mid-midrib and 32 cases of near-midrange staggered, after treatment were neutral relationship. CONCLUSION: Orthotopic traction orthodontics is effective and effective in the treatment of osteofacial malformations. It is also satisfied that the correction of supraspinatus and deformity correction, even during the rapid growth and development phase, is completed by means of extra-oral gravity and long-term traction effect.
