为避免术后急症的风险，研制了一种新的颌间超弹性镍钛合金结扎钢丝连续固定方法。用差示扫描量热法、三点弯曲试验和紧固试验研究了钢丝的基本性能。Ni-Ti合金丝的相变温度在适宜体温下表现出超弹性的范围内。镍钛合金丝具有足够的弯曲柔韧性，可用于连续接线方法，并在紧固试验中表现出较大的可恢复位移。利用这些特性，可以获得在紧急情况下容易移除和均匀固定。
A new continuous wiring method of intermaxillary fixation with super-elastic Ni-Ti alloy ligature wires was developed to avoid the risk in postoperative emergency. Differential scanning calorimetry, three-point bending tests and fastening tests were carried out to investigate basic properties of the wires. Transformation temperatures of the Ni-Ti alloy wires were in the range suitable for exhibiting superelasticity at body temperature. The Ni-Ti alloy wires possessed enough bending flexibility to be used in the continuous wiring method and showed great recoverable displacement in the fastening test. With use of these properties, easy removal in an emergency and uniform fixation can be attained.
