摘要
目的观察铸造固定式双垫矫治青春期安氏Ⅱ类1分类错的临床效果。方法回顾性分析30例青春期安氏Ⅱ类1分类错患者,均给予铸造固定式双垫功能矫治器治疗,在患者治疗前、后均行头颅侧位X线检查,比较SNA、SNB及ANB角,OJ(前牙覆盖值)、Wits值、L1-MP(下切牙—下颌平面角)、U6-PTM(上颌第一磨牙颊沟—翼上颌裂)、Go-Gn(下颌体长度)、Co-Go(下颌支长度)、Co-Gn(下颌长度)、Co-S(髁突后切线一蝶鞍中心距)、Sn-A-UL(鼻唇角)、Li-Si-Pg’(颏唇角)等指标。结果治疗前后SNA及U6-PTM两项指标上差异均无统计学意义(P>0.05);ANB、OJ、Wits值、Co-S等指标治疗后较治疗前减小,差异有统计学意义(P<0.05);SNB、L1-MP、Go-Gn、Co-Go、Co-Gn、Sn-A-UL、Li-Si-Pg’等指标治疗后较治疗前增加,差异有统计学意义(P<0.05)。结论对于青春期安氏Ⅱ类1分类错患者,应用铸造固定式双垫功能矫治器矫治,具有较好的临床效果。
Objective To evaluate the casting fixed Twin?block appliance on the clinical effects of growing children with skeletal Angle Class Ⅱdivision 1 malocclusion. Methods 30 patients with skeletal Angle ClassⅡdivision 1 malocclusion were treated by fixed casting Twin-block. Cephalometric data before and after the treatment were measured and analyzed. Results Difference of SNA and U6?PTM between pretreatment and post-treatment was not statistically significant (P > 0.05), there was statistically significance of diminution in ANB, OJ or Wits appraisal which decreased after treatment and augment in SNB, Go-Gn, Co- Gn, L1-MP, Sn-A-UL、Li-Si-Pg' which changed after treat?ment of fixed casting Twin-block (P < 0.05). Conclusion Treatment of casting fixed Twin?block is effective in the early treatment of skeletal Angle Class Ⅱdivision 1 malocclusion.
