本文对19名单侧完全性唇腭裂术后反 患者的正畸治疗做了分析,并对10名患者正畸治疗后颅面形态与口颌功能的变化做了说明。(1)患者经过正畸治疗,颅面形态的改变多为牙齿、齿槽的变化,软硬组织侧貌改善不理想,但患者下唇外翻得到改善。(2)正畸治疗后,患者息止间隙减小,下颌各种功能运动得到改善,颞颌关节状况改善。(3)经过正畸治疗,咀嚼肌功能得到提高,肌肉活动协调,但唇肌肌电活动无明显变化。
In this paper, we analyzed the orthodontic treatment of 19 patients with unilateral complete cleft lip and palate after operation, and described the changes of craniofacial morphology and oral function after orthodontic treatment in 10 patients. (1) Orthodontic treatment of patients, the change of craniofacial morphology mostly teeth, alveolar changes, soft and hard tissue to improve the profile is not ideal, but patients with lower lip eversion improved. (2) After orthodontic treatment, the patient's resting clearance decreased, various functional motor movements improved, and the status of temporomandibular joint improved. (3) after orthodontic treatment, masticatory muscle function was improved, muscle activity coordination, but no significant changes in the lip muscle myoelectric activity.
