“…The most widely implemented bio-inert metals are surgical stainless steel (316L), cobalt-chromium (CoCr) alloys, and titanium (Ti) alloys (2). Due to their superior mechanical, fatigue, wear, and corrosion resistance, Ti-6Al-4 V alloy [78], 316L stainless-steel (SS) [79], Co-Cr-Mo [80], and nickel-titanium shape memory alloy (NiTi-SMA) [1,[81][82][83][84][85][86][87][88][89][90][91][92] are frequently chosen over other biomaterials like polymers and ceramics…”

Biomaterials are listed in advanced materials that have high biocompatibility which can easily adapt to the system in which they are implanted without leaving any adverse reactions and side effects. Due to their interesting properties such as biocompatibility, bioactivity, degradability, long-term stability, and many other important properties, all four main types of biomaterials (Bioceramics, Metallic biomaterials, Biopolymers, and Biocomposites) can be used in the medical field, either for medical treatment by implanting them in the human body, or the manufacturing of advanced medical devices. In this review, a comprehensive introduction to biomaterials has been mentioned. Also, the general properties of biomaterials are explained especially these interesting properties that are helpful to use in the medical field. And finally, the medical applications of each of the different types of biomaterials have been reviewed.

“…Previous studies conducted by our team [16][17][18] and results from other research groups [19][20][21][22][23][24][25] have shown the potential of shape memory alloys (SMAs), especially nickel-titanium (NiTi), as components for implant applications. NiTi shows sufficient biocompatibility compared to other implant materials, such as Titanium and Titanium alloys, nickel-free stainless steel, or magnesium alloys [26][27][28][29][30][31][32]. Depending on the requirements of the implants or components, NiTi can be coated, for example with hydroxyapatite [33] or diamond-like coating (DLC) [26], to improve corrosion resistance or biocompatibility.…”

Hip implants have a modular structure which enables patient-specific adaptation but also revision of worn or damaged friction partners without compromising the implant-bone connection. To reduce complications during the extraction of ceramic inlays, this work presents a new approach of a shape-memory-alloy-actuator which enables the loosening of ceramic inlays from acetabular hip cups without ceramic chipping or damaging the metal cup. This technical in vitro study exam-ines two principles of heating currents and hot water for thermal activation of the shape-memory-alloy-actuator to generate a force between the metal cup and the ceramic inlay. Mechanical tests concerning push-in and push-out forces, deformation of the acetabular cup according to international test standards, and force generated by the actuator were generated to prove the feasibility of this new approach to ceramic inlay revision. The required disassembly force for a modular acetabular device achieved an average value of 602 N after static and 713 N after cyclic loading. The actuator can provide a push-out force up to 1951 N. In addition, it is shown that the necessary modifications to the implant modules for the implementation of the shape-memory-actuator-system do not result in any change in the mechanical properties compared to conventional systems.
