目的观察功能矫治器FR-Ⅲ与上颌牙合垫矫治器联合应用治疗替牙期前牙反牙合的效果。方法选择替牙期前牙反牙合患者24例,白天戴用上颌牙合垫矫治器,晚上戴用FR-Ⅲ矫治器,治疗前后拍摄头颅侧位片进行头影测量分析。结果24例患者均在1个月左右前牙呈对刃关系,5个月后中性牙合关系完全建立,面型获得较大改善。结论FR-Ⅲ矫治器与上颌牙合垫矫治器联合应用,既能快速解除前牙反牙合,诱导后牙建立正常咬合关系,又能促进上颌骨发育,抑制下颌向前生长。
Objective To observe the effect of functional appliance FR-Ⅲ combined with maxillary occlusal pad appliance on the treatment of anterior occlusal occlusion. Methods Twenty-four patients with anti-occlusal anterior teeth were selected during the day, wearing the maxillary occlusal pad appliance during the day and FR-Ⅲ appliance at night. The cephalometric films were taken before and after treatment. Results All the 24 patients presented an edge-to-edge relationship in one month or so. Neutral occlusal relationship was completely established after 5 months, and the facial shape was greatly improved. Conclusion The combined application of FR-Ⅲ appliance and maxillary occlusion pad appliance not only can quickly release anti-occlusion of the anterior teeth and induce normal occlusion of the posterior teeth, but also can promote maxillary development and inhibit the forward growth of the mandible.
