Methods: 16 patients aged 13~ 16 years with Angle Class II or Class I malocclusion underwent the treatment by improved biteplate for 3 months, the width of mandibular arch between 66 and between 33 was measured after treatment. 方法选择16例安氏II类1分类和I类上前牙唇倾患者经戴用上颌全腭导板3个月后分别记录治疗前后下颌牙弓宽度的变化,并做统计学处理。
Measurement of pre-and post bite-opening cast with inclined biteplate 固定斜面导板打开咬合前后的模型测量研究
The effect of the improved maxillary biteplate on the width of mandibular arch Conclusion The lip bumper could play an important role in the mandibular arch development and lower facial profile improvement in mixed and early permanent dentition. 上颌全腭导板对下颌牙弓宽度的影响研究结论在儿童颌面部生长发育高峰期,唇挡可有效促进下颌牙弓生长发育,改善面下部硬软组织侧貌形态。
