目的探讨Er:YAG激光不同模式、不同参数照射对种植体SA、SLA、Xpeed及RBM表面微形貌的影响。方法选择波长为2940 nm的Er:YAG激光并设置为软组织模式及参数50 mJ、10 Hz,100 mJ、10 Hz,200 mJ、10 Hz;设置硬组织模式及参数100 mJ、10 Hz,200 mJ、10 Hz。均在水冷却环境下,采取非接触模式,工作尖距离种植体表面1 mm,对SA、SLA、Xpeed及RBM 4种种植体表面固定一点照射5 s。用扫描电子显微镜(SEM)观察照射前后表面微形貌的变化。结果SEM观察可见,SA表面在软组织模式50 mJ、10 Hz及100 mJ、10 Hz照射下无变化,能量提高到200 mJ、10 Hz可见表面微形貌部分熔化;SLA表面在软组织模式50 mJ、10 Hz照射下无变化,能量提高到100 mJ、10Hz及200 mJ、10 Hz可见表面部分熔化及完全熔化;SA及SLA表面在硬组织模式100 mJ、10 Hz或200 mJ、10 Hz照射下,表面无变化。Xpeed和RBM表面在软组织模式50 mJ、10 Hz照射下分别表现为高峰塌陷和片状熔化;在能量提高到100 mJ、10 Hz及200 mJ、10 Hz均可见部分熔化及完全熔化;Xpeed及RBM表面在硬组织模式100 mJ、10 Hz照射下无变化,能量提高到200 mJ、10 Hz可见部分熔化;Xpeed表面未见涂层剥脱。结论本研究显示,在用Er:YAG激光处理种植体表面时,为避免对种植体表面造成损伤,SA和SLA表面用软组织模式时能量参数需设置在50 mJ、10 Hz以下,硬组织模式时参数设置200 mJ、10 Hz以下。Xpeed及RBM表面不适合用软组织模式处理,可在硬组织模式100 mJ、10 Hz以下处理。
Objective This work aimed to investigate the effects of Er:YAG laser irradiation with different modes and parameters on the micromorphology of implant SA,SLA,Xpeed,and RBM surfaces.Methods An Er:YAG laser with wavelength of 2940 nm was selected under the soft tissue mode(parameter settings of 50 mJ,10 Hz;100 mJ,10 Hz;and 200 mJ,10 Hz)and hard tissue mode(parameter settings of 100 mJ,10 Hz and 200 mJ,10 Hz).Under water cooling with the non-contact mode,the working tip was 1 mm away from the surface of the implants.One point on SA,SLA,Xpeed,and RBM surfaces was irradiated for 5 s.Micromorphological changes of the surfaces before and after laser irradiation were observed under scanning electron microscope(SEM).Results Under SEM observation,for the SA surface in the soft tissue mode,no change was observed under irradiation at 50 mJ,10 Hz and 100 mJ,10 Hz.When the energy was increased to 200 mJ,10 Hz,the micromorphology of the surface was partially melted.For the SLA surface in the soft tissue mode,no change was noted under 50 mJ,10 Hz irradiation.When the energy was increased to 100 mJ,10 Hz and 200 mJ,10 Hz,partial melting and complete melting were observed,respectively.For the SA and SLA surfaces,no changes were observed under the hard tissue mode with 100 mJ,10 Hz and 200 mJ,10 Hz irradiation.For the Xpeed surface and RBM surface in the soft tissue mode under 50 mJ,10 Hz irradiation,the surface peak collapsed and melted flakily,respectively.When the energy was increased to 100 mJ,10 Hz and 200 mJ,10 Hz,partial melting and complete melting were observed on both surfaces,respectively.For the Xpeed surface and RBM surface,no change was observed under 100 mJ,10 Hz irradiation in the hard tissue mode,whereas partial melting was observed when the energy increased to 200 mJ,10 Hz.No coating peeling was observed on the Xpeed surface.Conclusion When treating implant surfaces with Er:YAG laser,the energy parameters should be set below 50 mJ,10 Hz in the soft tissue mode and below 200 mJ,10 Hz in the hard tissue mode for the SA and SLA surfaces to avoid damage to the implant surface.The soft tissue mode was not suitable for the Xpeed and RBM surfaces,but they could be treated below 100 mJ,10 Hz in the hard tissue mode.
