摘要:
目的 通过测试并比较480℃加热退火处理的四种不同品牌，直径为φ0.8 mm牙用不锈钢丝的电镜断口形貌和拉伸断裂机制，为临床选用适宜的牙用不锈钢丝制备颊侧多曲簧提供一定的参考。方法 选用弯制颊侧多曲簧的直径为φ0.8 mm的上齿牌、上海康桥牌、锋棱牌、上海荣祥牌的牙用不锈钢丝，应用万能拉伸仪测量比较四种材料480℃加热退火后的拉伸试验、金相组织微观测试及EDX能谱分析。结果 四种不同品牌的牙用不锈钢丝在480℃加热退火处理下，直径为φ0.8 mm锋棱牌牙用不锈钢丝拉伸能力最好，电镜观察见韧窝大小不一，深浅有别，Ni含量最高，更适合临床弯制颊侧多曲簧。结论 直径为φ0.8 mm锋棱牌牙用不锈钢丝较其他品牌牙用不锈钢丝，更适合弯制颊侧多曲簧，可考虑临床应用。
Abstract:
Objective To test and compare the electron microscopic fracture morphology and tensile fracture mechanism of four different brands of dental stainless steel wire with diameter φ0.8 mm heated and annealed at 480℃, and prepare the buccal multi-curve for the clinical selection of dental stainless steel wire. The spring provides a certain reference. Methods The upper teeth of the curved cheek side multi-curved spring with diameter φ0.8 mm, Shanghai Kangqiao brand, Fengling brand, Shanghai Rongxiang brand dental stainless steel wire were selected, and the four materials 480℃ were measured by universal tensile tester. Tensile test after heating and annealing, metallographic microstructure microscopic test and EDX spectrum analysis. Results Four different brands of dental stainless steel wire were heated and annealed at 480℃. The diameter of φ0.8 mm was the best for the stainless steel wire. The electron microscopic observation showed that the dimples were different in size and different in depth. The highest Ni content is more suitable for clinically curved buccal multi-curved springs. Conclusion The φ0.8 mm diameter ribbed stainless steel wire is more suitable for bending the buccal multi-curved spring than other brands of dental stainless steel wire, which can be considered for clinical application.
