Abstract Magnesium (Mg) and its alloys have been proposed as degradable replacements to commonly used orthopedic biomaterials such titanium stainless steel. However, the corrosion of Mg in a physiological environment remains difficult characteristic accurately assess with vitro methods. The aim this study was identify simple immersion test that could provide rates similar those observed vivo . Pure five (AZ31, Mg‐0.8Ca, Mg‐1Zn, Mg‐1Mn, Mg‐1.34Ca‐3Zn) were immersed either Earle's balanced...

Abstract A systematic investigation of a series magnesium–calcium binary alloys is presented to reveal the influence increasing calcium (Ca) additions on in vitro degradation magnesium (Mg). Because its prevalence structural tissues, Ca among most biologically viable orthopedic‐intended Mg‐based biomaterials. Hence, fundamental electrochemical study Mg biomaterials essential continued role as an alloying addition. In this work, conditions closer physiological environment were implemented...

Hydroxyapatite, renowned for its biocompatibility and osteoconductive properties, plays a fundamental role in bone regeneration owing to resemblance natural mineral, thus offering considerable potential advancing tissue engineering strategies. In this article, the innovative integration of silicon ions into biogenic (bovine-derived) hydroxyapatite (SiBHA) via tailored sol-gel process is reported. The resultant SiBHA scaffolds exhibited an interconnected microporous structure with total...

Treatment planning for dental implant patients is often complicated by the unknown extent of anterior loop mental neurovascular bundle. The aim this study was to determine correlation between visual interpretation panoramic radiographs and anatomical dissection findings in a cadaveric sample. Panoramic 22 randomly selected coronally sectioned human head specimens were taken using Scanora (Soridex, Orinon Corporation Ltd, Helsinki, Finland) radiographic unit jaw panorama (Programme 001,...

The development of advanced materials from biorenewable protein biopolymers requires the generation more exogenous bonds to maintain microstructure and durability in final products. Casein is main milk, representing about 80% total protein. In present investigation casein was solubilized and/or emulsified aqueous alkaline solutions, 2D films 3D matrices were produced. effects silane (3-aminopropyl triethoxy silane), DL-glyceraldehyde glutaraldehyde on tensile properties water...

Abstract The use of porous metal foams as biomaterial scaffolds has been widely adopted; however, many these structures are manufactured with pore architectures that inherently random. This makes structural optimization for a specific purpose challenging. Scaffolds containing ordered can be fabricated to meet design criteria, such porosity, stiffness, and volume fraction. Mg its alloys offer potential new class degradable metallic orthopedic biomaterials. In comparison current implant...

Abstract Reconstituted keratin has shown promise as an orthopaedic biomaterial. This in vivo study investigates the biological response of composite materials prepared from reconstituted containing a high content hydroxyapatite (HA) (40 wt % HA), implanted for up to 18 weeks long bones sheep. Keratin–HA composites were compared with commercially available polylactic acid (PLA) HA (BIO RCI HA®, Smith and Nephew). Porous keratin–HA displayed excellent biocompatibility osseointegration, full...

Abstract The relationship between surface roughness and degradation behavior in magnesium (Mg) biomaterials is still a controversial issue. This study aims to clarify the corrosion rate of pure Mg. Pure Mg samples with values (Ra) 0.59, 2.68, 9.12 μm were cast using an indirect solid‐free form fabrication method. vitro was evaluated hydrogen evolution, mass loss, potentiodynamic polarization, electrochemical impedance spectroscopy. It confirmed that had significant influence on Mg,...
