导出了导线性能的一般公式。这些使传统的正畸合金和最新的弓丝材料之间的比较。对于六种常见的弓丝尺寸，物理性能考虑表明Ni-Ti是最活跃的”调平”弓丝，B-Ti是需要柔韧性的上级中间弓丝，SS和Co-Cr是精加工和需要形状稳定性的其他应用的首选弓丝。这些结论是基于目前对等效力系的理解和每个一般分类的力学性质。这些电线或其他一些电线是否用于未来的病人护理将取决于一个不确定和悲观的经济预测。目前的观点是，最大的需求是制定经验方程，更好地描述三股弓丝在弯曲和更准确的物理性能数据的所有线在拉伸和扭转状态下的行动。这种额外的信息对于医生在改变成本和可用性的条件下选择最佳弓丝非常有用。
General formulas for wire properties have been derived. These enable comparisons among conventional orthodontic alloys and latest archwire materials. For six common archwire sizes, physical property considerations indicate that Ni-Ti makes the most active" leveling" archwire, the B-Ti is a superior intermediate archwire where flexibility is required, and that SS and Co-Cr are the wires of choice for finishing and other applications where stability of form is required. These conclusions are based on the current understanding of equivalent force systems and the mechanical properties of each general classification. Whether these wires or some others are used in future patient care will depend on an uncertain and gloomy economic forecast. The present viewpoint is that the greatest needs are the formulation of empirical equations that better describe the action of triple-stranded archwire in bending and more accurate physical property data for all wires in both the tensile and the torsional states. Such additional information could be very useful to the practitioner in choosing the optimal archwire under changing conditions of cost and availability.
