Commonly, clinicians' principal tool in the alignment phase of orthodontic mechanotherapy is the nickel-titanium wire. During the course of orthodontic treatment, however, there are times when some segments of the dental arch require flexible wires, while the rest would benefit from rigid wires. In this report, we describe a technique where both of these needs are satisfied simultaneously. Specifically, a segment of nickel-titanium wire is piggybacked onto a stainless steel wire in regions where flexibility is desired. This method eliminates the problems associated with the activation, de-activation forces created along a continuous archwire and might be more economical. Clinical pictures illustrate the point.
通常，在正畸机械治疗的排齐阶段，临床医生的主要工具是镍钛丝。然而，在正畸治疗过程中，有时牙弓的某些部分需要使用柔韧性好的钢丝，而其余部分则使用刚性钢丝会更有益。在本报告中，我们描述了一种能同时满足这两种需求的技术。具体而言，在需要柔韧性的区域，将一段镍钛丝搭载在不锈钢丝上。这种方法消除了与沿连续弓丝产生的激活和去激活力相关的问题，并且可能更经济。临床图片说明了这一点。
