目的:在前牙反牙合矫治中应用一种小型下颌后退位牙合板后退下颌,评价其矫治AngleⅢ类功能性-轻、中度骨性前牙反牙合病例的临床应用效果。方法:应用小型下颌后退位牙合板治疗反牙合328例。在打开咬合的同时后退下颌,同时粘固上下颌托槽进行排齐整平。结果:患者侧貌在戴用后退位牙合板后明显改善,下颌的有效后退使反牙合的矫治变得简单化,治疗时间较传统矫治明显缩短。远期随访疗效肯定。结论:小型下颌后退位牙合板适用于下颌可适度后退的前牙反牙合病例,可快速矫治前牙反牙合。是较固定反式TBA联合前牵引更为理想的装置,结构更小巧,制作更简便,更适用于临床应用。
OBJECTIVE: To evaluate the clinical effect of Angle ¢ ñ-functional orthodontics in the treatment of anterior teeth anti-orthodontics using a small mandibular retreat plinth. Methods: A total of 328 cases of anti - occlusion were treated with small mandibular retreat plinth. Open the occlusion while retreating the jaw, while the upper and lower jaw bracket for alignment and leveling. Results: The appearance of the patient was significantly improved after wearing the retreat plinth. The effective retreat of the mandible made the orthodontic treatment easier and the treatment time was significantly shorter than that of the traditional one. Long-term follow-up effect is positive. Conclusion: The small mandibular recumbent occlusal plate is suitable for anterior crossbite patients with moderate mandibular retraction, which can rapidly correct anterior crossbite patients. Is a more fixed trans-TBA joint pre-traction device is more ideal, the structure is more compact, easier to make, more suitable for clinical applications.
