Hydroxyapatite (HA) coatings on metallic implants have been extensively used in orthopedic applications to improve tissue-implant interactions, enhance their biocompatibility, and functionality. However, the expensive synthetic HA is most widely bioceramic for implant coatings, leading high costs. Hence, this research explored potential of an inexpensive biogenic derived from fish scales FsHA/y...

The present study examined the in vitro and vivo bone formation adhesion ability on surface of a titanium dental implant made by plasma electrolytic oxidation (PEO) electrolytes containing bioactive ions. To achieve this goal, screw-shaped fabricated Ti-6Al-4V alloy implants were processed via PEO using an electrolyte solution calcium (Ca), phosphorous (P), magnesium (Mg), zinc (Zn), strontium ...

Development of additive technologies and biocompatible materials facilitated their use in the custom-made implants manufacture. Verification of custommade implants manufactured using the additive manufacturing technologies is the key task to be fulfilled prior to the clinical application of an implant. It consists of parameters verification within individual steps, from a software design, throu...

Laser surface modification of Ti-6Al-4V with an existing calcium phosphate coating has been conducted to enhance the surface properties. The electrochemical and mechanical behaviors of calcium phosphate deposited on a Ti-6Al-4V surface and remelted using a Nd:YAG laser at varying laser power densities (25-50 W/mm(2)) have been studied and the results are presented. The electrochemical propertie...

(1) Background: Metallic materials are predominantly used for spinal implants, and they can damage adjacent bones intervertebral discs (IVDs) owing to their high elastic moduli. Consequently, there is a possibility that serious complications, such as kyphosis, may occur the sequelae progresses. In this study, behavior of lumbar spine implant system was evaluated using finite element (FE) method...

Titanium has been one of the traditional metals used in medical industry since 1940. This work modeled and simulated a hip-joint replacement implant using Creo 5.0 DEFORM 3D (v11.0), respectively. Four titanium-based billets were modeled; out four billets, three coated with specified thickness, was uncoated. Among billet 500-micron two 1000-micron thickness. At end simulation, coating materials...

Abstract Titanium alloys are ideally suited for use in implant or osteosynthesis applications due to their good mechanical properties, corrosion resistance, and biocompatibility. In terms of higher strength applications, Ti–6Al–4V Ti–6Al–7Nb frequently used. However, both contain the alloying elements aluminum and, former case, vanadium, which could have toxic effects on human body. Therefore, ...

In present work, prediction the effect of nose radius, rz (mm) on the equivalent strain (PEEQ) and surface finish during the machining of titanium alloy (Ti-6Al-4V) through orthogonal cutting process. The results were performed at several of the nose radiuses, rz (mm) while the cutting speed, vc (m/min), feed rate, f (mm/tooth) and depth of cut, d (mm) were remained constant. The equivalent pla...
