本文应用 MBTR—1型测力仪,测定了不锈钢丝、钛镍丝的各种唇弓和弹簧的变形力。结果钛镍丝的变形力比不锈钢丝低1～5倍。并提出设计矫正器时对丝材选择的三项要求,以供正畸科医师参考。
In this paper, MBTR-1 dynamometer was used to measure the deformation force of various lip and spring of stainless steel wire and titanium nickel wire. Results The deformation force of titanium-nickel wire is 1 to 5 times lower than that of stainless steel wire. And put forward the design of orthosis three requirements for wire selection for orthodontic reference.
