摘要(Abstract)：

目的:在Typodont上对改良设计的铸造横腭弓进行初步研究。方法:选取错牙合畸形患者30例,上颌模型按要求翻制3副正畸模拟模型,根据装配的横腭弓类型分为对照组、传统组及改良组,观察其在三维方向上对支抗磨牙的影响。结果:改良组和传统组各检测指标均低于对照组,有统计学意义(P<0.05),改良组和传统组比较,伸长位移指标无统计学意义(P>0.05),其余指标两组间差异均有统计学意义(P<0.05)。结论:改良铸造金属横腭弓是一种良好的增强磨牙支抗的方法。
Objective: To study the feasibility of improved casting metal transpalatal arch preliminarily.Methods: Thirty patients with malocclusion deformity were chosen.Three typodont copies of maxillary model were made according to the requirement and were divided into control group,traditional group and improved group according the types of assembled transpalatal arches.The influences of different transpakatal arches on anchorage molars in 3D directions were observed.Results: All the detecting indexes of improved group and traditional group were lower than those of control group(P<0.05).There was no statistical difference in elongation displacement index between improved group and traditional group(P>0.05),and statistical differences were found in the other indexes between the two groups(P<0.05).Conclusions: Improved casting metal transpalatal arch is a good method for enhancing molar anchorage.
