Magnesium (Mg) is one of the most plentiful elements in the Earth’s crust and seawater. It possesses low density, high specific strength, high standard potential, and good biocompatibility. In addition, magnesium hydride shows the highest energy density of all reversible metallic hydrides applicable for hydrogen storage. These unique features make Mg and its alloys a class of very promising material for structural and functional applications pertaining to aerospace, transportation, and biomedical and energy sectors. Wide applications of Mg alloys are thus deemed to significantly contribute to the ever-increasing environmental problems and energy challenges in the worldwide.

目的拟采用临床回顾性研究的方法,对比3D打印个性化钛网(3D-PITM)辅助下的引导骨再生(guided bone regeneration,GBR)与块状自体骨移植在复杂牙槽骨缺损重建中的骨增量效果。方法纳入2018年5月至2022年1月就诊于重庆医科大学附属口腔医院种植科的39名牙槽骨缺损种植患者,根据其骨增量术式不同分为3D-PITM+GBR组(19名)和自体骨Onlay组(20名)。术前拍摄CBCT影像导入Mimics-Research和3-Matic软件进行三维重建与数字化设计,采用计算机辅助设计(CAD)/激光选区熔融(SLM)技术制作3D-PITM。术中固定3D-PITM或自体骨块完成相应的骨增量手术。收集患者术前、植骨术后、术后6~9个月、种植体植入后的CBCT影像资料。基于CBCT数字影像资料,分别测量两组患者在种植体中轴线上牙槽骨增加的高度,以及在种植体平台下方0 mm、2 mm、4 mm处牙槽骨增加的宽度,并计算其成骨率。结果3D-PITM+GBR组在骨增量前后和种植前后的垂直骨增量[2.68 mm(0.45,4.23)、2.27 mm(0.49,3.27)]均高于块状自体骨移植[1.60 mm(0.33,1.62)、1.74 mm(0.53,1.60)]。3D-PITM+GBR组在骨增量前后牙槽嵴顶下方0 mm、2 mm、4 mm平均骨宽度增量[(1.97±0.97)mm、(2.59±1.22)mm、(2.94±1.50)mm]高于块状自体骨移植[(1.06±0.99)mm、(1.45±1.25)mm、(2.32±1.23)mm]。3D-PITM+GBR组在种植前后种植体平台下方0 mm、2 mm、4mm平均骨宽度增量[(2.34±1.09)mm、(2.53±1.48)mm、(2.85±2.20)mm]反低于块状自体骨移植[(2.51±1.34)mm、(3.04±1.73)mm、(3.38±1.94)mm]。3D-PITM+GBR组在水平方向和垂直方向的成骨率(66.8%,68.8%)均高于块状自体骨Onlay移植组(64.6%,62.6%)。3D-PITM用于重建复杂牙槽骨缺损能够较块状自体骨移植明显提高牙槽骨重建的高度和宽度,但植入物暴露率(21%)仍高于自体骨Onlay组(5%)。结论3D-PITM+GBR技术可代替块状自体骨移植用于重建复杂牙槽骨缺损,获得理想的骨增量效果和稳定的骨轮廓,但钛网暴露仍是其应用的常见并发症。

To have a better understand on the change of microstructure via kinetics, the diffusion behavior of Mg alloys is of special interest to researchers. Meanwhile, diffusion coefficients of Mg based alloys can explain and represent their diffusion behavior well. The evolution of experimental and calculated methods for detecting and extracting diffusion coefficients was discussed briefly. The reasonable diffusion data, especially self-diffusion coefficients, impurity diffusion coefficients and inter-diffusion coefficients of Mg alloys, were reviewed in detail serving to design the Mg alloys with higher accuracy. Then the practical applications of diffusion coefficients of Mg alloys were summarized,including diffusional mobility establishing, precipitation simulation and mechanical properties prediction.

Magnesium and its alloys have such advantages with lightweight, high specific strength, good damping, high castability and machinability,which make them an attractive choice for applications where weight reduction is important, such as in the aerospace and automotive ***, their practical applications are still limited because of their poor corrosion resistance, low high temperature strength and ambient formability. Based on such their property shortcomings, recently degradable magnesium alloys were developed for broadening their potential applications. Considering the degradable Mg alloys for medical applications were well reviewed, the present review put an emphasis on such degradable magnesium alloys for structural and functional applications, especially the applications in the environmental and energy fields. Their applications as fracture ball in fossil energy, sacrificial anode, washing ball, and as battery anodes, transient electronics, were summarized. The roles of alloying elements in magnesium and the design concept of such degradable magnesium alloys were discussed. The existing challenges for extending their future applications are explored.
