摘要:
目的 探究澳丝在口内环境中使用一段时间后,对其机械性能及表面形貌的影响。为临床上寻找合理的更换时机提供参考。方法 选择0.014英寸、0.016英寸两种不同型号的澳丝,分别在口内使用1~5个月。使用后回收作为样本,分别检测其机械性能及表面形貌并与新弓丝进行比较。结果 0.014、0.016英寸两种尺寸的澳丝在口腔中使用长达5个月后其弹性较新丝相比,差异无统计学意义(P>0.05)。但扫描电镜显示,澳丝在口内使用状态下,随着使用时间的延长,其表面发生了明显的腐蚀现象。结论 在口内使用长达5个月的时间内澳丝可以保持良好的弹性,但随着使用时间增长,弓丝表面变得粗糙。
Abstract:
Abstract:Objective To explore the effect of Australian silk on its mechanical properties and surface topography after a period of time in oral environment.It provides reference for finding reasonable replacement time in clinic.Methods Choose 0.014 inches and 0.016 inches of two different types of Australian silk,respectively,for 1~5 months in mouth.After recycling,the mechanical properties and surface morphology of the samples were measured and compared with the new archwires.Results There was no significant difference in elasticity between two Australian wires of 0.014 and 0.016 inches after being used in oral cavity for up to 5 months compared with that of new silk(P>0.05).But scanning electron microscope showed that the surface of Australian silk was corroded obviously with the prolongation of time.Conclusion Australia silk can maintain good elasticity after oral use for 5 months,but the surface of arch silk becomes rough with the increase of service time.
