锻丝卡扣的灵活性与许多因素有关,包括合金的类型和规格。本研究的目的是比较五种锻丝合金用于可摘局部义齿的弯曲行为。合金及其表径(毫米)分别为Ticonium(18,19,20)、铂-金-钯(18,19)、Wironium(18,20)、Jelenko Standard(18,19,20)和Denture Clasp(18,19,20)。每种牙科合金共测试12至15个样品。在由计算机控制的伺服液压测试系统上以1.00 mm/秒的速度进行三点弯曲,直到发生断裂或执行器接触。在弯曲时测定了每个直径的最大应力和弹性模量。方差分析和事后Scheffe统计分析显示,同一规格的不同合金和同一合金的不同规格的弯曲差异中最大应力和弹性模量显著。变形丝可摘局部义齿合金的弯曲力学性能受到材料选择和管径的显著影响。Ticonium合金在各个水平的弹性模量最大(最硬),而Denture buckle和Jelenko Standard合金的弹性模量最低(最灵活)。这些数据表明,在选择金属卡扣时,合金的弯曲性能与规格尺寸同样重要。
The flexibility of the wrought wire clasp is related to a number of factors, including the type and gauge of the alloy. The purpose of this study was to compare the bend behavior of five wrought wire alloys used in removable partial dentures. The alloys and their gauge diameters (in millimeters) were Ticonium (18, 19, 20), platinum-gold-palladium (18, 19), Wironium (18, 20), Jelenko Standard (18, 19, 20), and Denture Clasp (18, 19, 20). A total of 12 to 15 samples of each dental alloy were tested. Three-point bending was performed on a servohydraulic testing system controlled by a computer at 1.00 mm/sec until fracture or actuator contact occurred. Maximum stress and elastic modulus in bending were determined for each gauge diameter. Analysis of variance and post hoc Scheffe statistical analyses revealed significant maximum stress and elastic modulus in bending differences for different alloys of the same gauge and for different gauges of the same alloy. The choice of material and the gauge diameter significantly influenced the mechanical property of bending for wrought wire removable partial denture alloys. The Ticonium alloy had the greatest elastic modulus (stiffest) at all levels and the Denture Clasp and the Jelenko Standard alloys had the lowest elastic modulus (most flexible). These data indicate that knowledge of the bending properties of an alloy is equally as important as the gauge size when selecting a wire clasp.
