The applications and research progresses of nickel–titanium shape memory alloy in reconstructive surgery

Abstract

In spite of some good successes and excellent researches of nickel-titanium shape memory alloy (NiTi-SMA) in reconstructive surgery, there are still serious limitations to the clinical applications of NiTi alloy today. The potential leakage of elements and ions could be toxic to cells, tissues and organs. This review discussed the properties, clinical applications, corrosion performance, biocompatibility, the possible preventive measures to improve corrosion resistance by surface/structure modifications and the long-term challenges of using SMAs.

Functionalization of the NiTi Shape Memory Alloy Surface by HAp/SiO2/Ag Hybrid Coatings Formed on SiO2-TiO2 Glass Interlayer

“…NiTi shape memory alloys (SMAs), with a chemical composition that is similar to the equilibrium, have outstanding properties, such as one-way-, two-way-shape memory effect (SME), superelasticity, and acceptable biocompatibility. They are the most common SMAs applied in a wide range of biomedical fields due to these features-for implants, especially in orthopedics, as well as surgical tools in medicine [1][2][3][4]. Unfortunately, the long-term use of NiTi alloy implants necessitates the improvement of their corrosion resistance and biocompatibility [5][6][7].…”

Key Factors Achieving Large Recovery Strains in Polycrystalline Fe–Mn–Si‐Based Shape Memory Alloys: A Review

“…Due to the integration of sensing and actuating, SMAs are considered as “intelligent” materials. As such, the SMAs have drawn significant attention and interest recently in a wide range of applications, such as biomedicine, actuation, energy conversion, aerospace, robotics, civil construction, damping, micro‐electromechanical systems (MEMS), and even fashion field …”

“…The NiTi shape memory alloys, with its chemical composition near to equal-atomic, reveal very good mechanical properties, high corrosion resistance and biocompatibility [1][2][3][4][5][6][7]. The unique features such as shape memory (SME) and superelasticity effects contributed to the many applications these alloys in a wide range of biomedical fields [1][2][3][4][5][6][7].…”
