大多数正畸设备都是由不锈钢，Co-Cr和Ni-Ti等合金制成的，因为它们具有优异的弹性性能。近年来，越来越多的审美需求、金属过敏和金属与磁共振成像的干扰推动了非金属正畸材料的发展。在本研究中，我们评估了三种超级工程塑料（PEEK， PES和PVDF）作为正畸金属丝的可行性。PES和PVDF表现出优异的美观性，尽管PEEK表现出最高的弯曲强度和抗蠕变性。PEEK和PVDF的吸水率都很低。由于PEEK颜色的最新发展，我们得出结论，PEEK具有许多有利的特性，使其适合用作美观的无金属正畸金属丝。
Most orthodontic equipment is fabricated from alloys such as stainless steel, Co-Cr and Ni-Ti because of their excellent elastic properties. In recent years, increasing esthetic demands, metal allergy and interference of metals with magnetic resonance imaging have driven the development of non-metallic orthodontic materials. In this study, we assessed the feasibility of using three super engineering plastics (PEEK, PES and PVDF) as orthodontic wires. PES and PVDF demonstrated excellent esthetics, although PEEK showed the highest bending strength and creep resistance. PEEK and PVDF showed quite low water absorption. Because of recent developments in coloration of PEEK, we conclude that PEEK has many advantageous properties that make it a suitable candidate for use as an esthetic metal-free orthodontic wire.
