Purpose: The aim of this work is to characterize the surface geometry of the orthodontic archiwire and their influence of the pitting corrosion resistance and bacterial adhesion. Design/methodology/approach: In the paper, the results of the SEM/EDS analysis and microscopic observation of the samples surface and analysis of geometrical structure with the use Atomic Force Microscope (AFM) and Confocal Microscopy were presented as well as the pitting corrosion test and surface roughness and microhardness measurements were performed. Additionally the microbiological study after bacterial breeding with the use Scanning Electron Microscope was carried out. Findings: In the basis of the investigation, it can be concluded that the surface geometry of archwire has a significant impact on their pitting corrosion resistance in artificial saliva solution and on the bacterial adhesion. The obtained results show satisfactory properties and surface geometry of the tested orthodontic wires for use in the human oral environment. Research limitations/implications: In the future, it is planned to extend the research with physicochemical properties and the influence of oral hygiene products on the corrosive behaviour of the material. Limitations in the conducted tests refer to archwire design – a small diameter making measurements difficult. Practical implications: The oral environment is an extremely aggressive corrosive environment. The orthodontic elements should have very good corrosion resistance and biocompatibility. The focus should be on continuously improving orthodontic wires in terms of material quality and topography of its surface topography. Originality/value: The research is conducted in the field of biomedical engineering, which is part of material engineering and is used for the field of dentistry and microbiology.

The paper presents the effect of ZrO2 layer deposition by the ALD process on the physicochemical properties of cobalt-based alloys (Realloy C and EOS CoCr SP2) intended for application in prosthetic dentistry. The paper shows the results of the surface roughness measurements made by the AFM method as well as the wettability and free surface energy measurements. Additionally, potentiodynamic tests of pitting corrosion resistance and electrochemical impedance spectroscopy in a solution of artificial saliva were carried out. Tests were carried out on the samples in the initial state and after surface modification with the ZrO2 layer. Based on these results, the usefulness (e.g. enhancement of corrosion resistance and biocompatibility) of the proposed ZrO2 layer on the cobalt alloys was assessed.

Stainless steel 316L is one of the most common metallic biomaterials used for implants. Its passive surface provides a good corrosion resistance in the body environment, which can be reduced by surface mechanical damages. This is the reason why the bone screws made of stainless steel 316L were subjected to laboratory analysis in the initial state, after diversified implantation period and after mechanical damage of the surface. The mechanical damages were estimated on the basis of stereoscopic and scanning electron microscope (SEM). In order to estimate the pitting and crevice corrosion resistance, potentiodynamic and potentiostatic examinations were performed. On the basis of obtained results it can be stated that despite the visible damages on the surface, the investigated screws present a good pitting corrosion resistance. However, the way the screws were fastened caused frictional corrosion and existing cavities led to crevice corrosion. Moreover, clear correlation between magnitude of mechanical damages of the surface, implantation time and screws corrosion resistance was observed.

Purpose: The fundamental aim of this research was to determine the biomechanical characteristics of the medical bed made of carbon steel and an assessment of its stability. To define the biomechanical characteristics of the bed design, the finite element method (FEM) was applied. Additionally, the risk analysis was conducted according to the directives of ISO 14971 standard. Design/methodology/approach: The research was carried out on the typical rehabilitation bed. To define the biomechanical characteristics of this equipment, the finite element method was applied. Geometric model of medical bed, was discretized by means of SOLID 95 element. Appropriate boundary conditions imitating phenomena in the real system with appropriate accuracy were established. The aim of biomechanical analysis was calculation of displacements and stresses in the bed’s construction elements in a function of the applied loading. In order to carry out calculations, 3 models of diverse variants of loading were selected – safe working load - model 1, transverse stability - model 2 and longitudinal stability - model 3. Findings: The analyses showed the difference in displacements, strains and stresses in the characteristic points depending on the selected loading. That also helped to determine maximal loading causing the exceeding of the yield stress of the bed’s components. Research limitations/implications: The limitations were connected with simplification of numerical model of femur as well as with the selected boundary conditions. Practical implications: The obtained results can be useful in the designing process (modification of requirements regarding design and construction, as well as materials used in the production of the device, and reduction of risk as far as possible to the patient). They prove that 3D geometrical analysis works quite well for assistive medical devices design. Originality/value: Stress-strain-displacement characteristics of the medical bed’s elements, obtained from the numerical analysis were presented in the work.
