Potential Prospective Application of Zr-Based Bulk Metallic Glasses in Dental Implant

Abstract

Zr-based bulk metallic glasses (BMGs) are being studied widely in recent years due to their unique mechanical properties. In this paper, we will present the progress in the studies of corrosion resistance behavior and biomedical potential of the Zr-based BMGs, especially the in vitro and in vivo evaluation of their biocompatibility. Owing to their high resistance to corrosion in a physiological environment and the excellent biocompatibility that give them a passive, stable oxide film, Zr-based BMGs are considered the material of choice for intraosseous use. The aim of this paper is to give an overview of the available literature on the Zr-based BMGs and present a promising prospect for the application of oral implant.

Review on Biocompatibility and Prospect Biomedical Applications of Novel Functional Metallic Glasses

“…This includes mainly Be and Ni, however, adverse effects were also observed for Cu [ 65 , 87 , 89 ] and can occur for a sufficient concentration of nearly all important Zr-based metallic glasses components [ 1 ] (e.g., Fe, Co, or Al). Because of their essentiality, getting rid of them is extremely difficult without worsening GFA, mechanical properties, or corrosion resistance [ 38 , 90 , 91 , 92 , 93 , 94 ]. Any deterioration of these functional properties can lead to a worse bio-performance for glassy alloys without the aforementioned elements, which are harmful on their own, than for the ones containing these elements.…”

“…In regards to MGs, it is the materials overall improved physical, mechanical, and chemical properties that have caught researchers attention. As a frozen liquid, MGs fail to crystallize during solidification, resulting in the absence of crystalline defects such as grain boundaries, dislocations and vacancies Zr‐based MGs are for example recognized by their high strength (1700 MPa) and hardness (590 HV), as well as relatively low elasticity (50–100 GPa for Zr‐based MGs compare to 3–50 GPa for the cortical bone) and corrosion rate in various aqueous environments. However, Zr‐based MGs has been reported to be susceptible to pitting corrosion in aqueous solutions containing halide ions (Cl − and F − ) due to the preferential absorption of Cl − and F − ions to the surfaces of the material .…”
