| 摘 要： | 目的:评价安氏Ⅱ类1分类错(牙合)病例临床矫治中反向Nance弓与横腭弓联合应用的支抗控制效果。方法:选择18.7-24.6岁安氏Ⅱ类1分类女性错(牙合)患者16例,分析联合应用反向Nance弓与横腭弓加强支抗治疗前后的X线头影测量值的变化。结果:(1)UMD与UMRD均有增大,但磨牙前移量被控制在拔牙间隙的1／5以内。(2)UMVD、MP-FH与ANS-Me均无显著性改变,支抗磨牙的垂直方向变化得到有效控制。(3)磨牙在水平方向上无舌向倾斜、移位及扭转。结论:反向Nance弓与横腭弓联合应用,能在三维方向上较好地控制支抗磨牙。

| Abstract: | PURPOSE: To evaluate the effects of combined reverse Nance and TPA on anchorage control. METHODS: 16 female adults with Class II division 1 malocclusion were treated with the combined mechanism of reverse Nance and TPA in an attempt to reinforce molar anchorage. Cephalometric analysis and model measurements were conducted for the assessment of anchorage control. RESULTS: The mesial movement of the upper first molars were minimized within 1/5 extracted space, parameters such as UMVD, MP-FH, ANS-Me remained unchanged, indicating the molar anchorage was controlled effectively. CONCLUSION: The modified combination of reverse Nance and TPA might be effective in anchorage forcement. |
