目标
比较使用各种类型的正畸金属丝通过激光焊接制成的同质和异质接头的偏转载荷特性。
材料和方法
使用四种直正畸矩形丝（0.017英寸×0.025英寸）：不锈钢（SS）、钴铬镍（Co-Cr-Ni）、β-钛合金（β-Ti）和镍钛（Ni-Ti）。均质和异质端对端接头（每个长 12 毫米）通过 Nd:YAG 激光焊接制成。使用两种类型的焊接方法：两点焊接和四点焊接。非焊接线也用作对照。挠曲载荷(N)通过进行三点弯曲试验来测量。使用方差分析/Tukey 检验对数据 (n = 5) 进行统计分析 (P < .05)。
结果
测量的控制线的挠曲载荷如下： SS：21.7±0.8N；钴铬镍：20.0±0.3N； β-Ti：13.9±1.3N； Ni-Ti：6.6 ± 0.4 N。与相应的控制焊丝相比，所有均质焊接样本均表现出较低的偏转载荷，与异质焊接组合相比，所有均质焊接样本均表现出较高的偏转载荷。对于均质组合，Co-Cr-Ni/Co-Cr-Ni 显示出比其余均质焊接组显着更高 (P < .05) 的偏转载荷。在异质焊接组合中，SS/Co-Cr-Ni 和 β-Ti/Ni-Ti 显示出比其余异质焊接组合更高的偏转载荷（SS/Co-Cr-Ni 明显更高）。两个因素（材料组合和焊接方法）之间的相互作用具有显着性（P < .01）。然而，在均质或异质组合中，四点焊接和两点焊接之间的偏转载荷没有显着差异。
结论
异质激光焊接的 SS/Co-Cr-Ni 和 β-Ti/Ni-Ti 丝提供的偏转载荷与均匀焊接的正畸丝相当。
OBJECTIVE
To compare the deflection load characteristics of homogeneous and heterogeneous joints made by laser welding using various types of orthodontic wires.
MATERIALS AND METHODS
Four kinds of straight orthodontic rectangular wires (0.017 inch × 0.025 inch) were used: stainless-steel (SS), cobalt-chromium-nickel (Co-Cr-Ni), beta-titanium alloy (β-Ti), and nickel-titanium (Ni-Ti). Homogeneous and heterogeneous end-to-end joints (12 mm long each) were made by Nd:YAG laser welding. Two types of welding methods were used: two-point welding and four-point welding. Nonwelded wires were also used as a control. Deflection load (N) was measured by conducting the three-point bending test. The data (n = 5) were statistically analyzed using analysis of variance/Tukey test (P < .05).
RESULTS
The deflection loads for control wires measured were as follows: SS: 21.7 ± 0.8 N; Co-Cr-Ni: 20.0 ± 0.3 N; β-Ti: 13.9 ± 1.3 N; and Ni-Ti: 6.6 ± 0.4 N. All of the homogeneously welded specimens showed lower deflection loads compared to corresponding control wires and exhibited higher deflection loads compared to heterogeneously welded combinations. For homogeneous combinations, Co-Cr-Ni/Co-Cr-Ni showed a significantly (P < .05) higher deflection load than those of the remaining homogeneously welded groups. In heterogeneous combinations, SS/Co-Cr-Ni and β-Ti/Ni-Ti showed higher deflection loads than those of the remaining heterogeneously welded combinations (significantly higher for SS/Co-Cr-Ni). Significance (P < .01) was shown for the interaction between the two factors (materials combination and welding method). However, no significant difference in deflection load was found between four-point and two-point welding in each homogeneous or heterogeneous combination.
CONCLUSION
Heterogeneously laser-welded SS/Co-Cr-Ni and β-Ti/Ni-Ti wires provide a deflection load that is comparable to that of homogeneously welded orthodontic wires.
