Opis:
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.

Opis:
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.

Opis:
The paper contains the results of the initial surface treatment influence on the properties of the medical Ti-6Al-7Nb alloy with a modified zirconium oxide layer deposited on its surface by sol-gel method. In the paper, the analysis of results of potentiodynamic studies is presented as well as its resistance to pitting corrosion and electrochemical impedance spectroscopy (EIS), macroscopic observation of the surface of samples and analysis of geometrical structure with the use Atomic Force Microscope (AFM) were performed. The studies were performed on two groups of samples depending on the graduation of the sand used in sandblasted process – 50 μm and 250 μm. Based on the obtained results it can be concluded that the type of the initial surface treatment preceding the surface modification of the Ti-6Al-7Nb has a significant effect on its properties.

Opis:
Celem pracy była ocena jakości stanu powierzchni implantu, która mogłaby wskazywać na przyczynę utraty integracji wszczepu śródkostnego. Badania obejmowały obserwacje mikroskopowe oraz analizę składu chemicznego wszczepu śródkostnego w mikroskopie skaningowym firmy ZEISS SUPRA 35 wyposażonego w detektor SE. Potwierdziły one wykonanie implantu ze stopu Ti- 6Al-4V oraz wskazały na zaistniały proces osteointegracji. Powodem utraty zintegrowanego wszczepu było prawdopodobnie przeciążenie mechaniczne oraz złe nawyki higieniczne, palenie tytoniu oraz współistniejąca choroba przyzębia i wywołane nią periimplantitis.
The aim of the study was the quality assessment of the state of the surface of the implant. The study included microscopic observations and analysis of the chemical composition of the implant intraosseous scanning microscope ZEISS SUPRA 35 equipped with a detector SE. They confirmed the execution of the implant alloy Ti-6Al-4V, and pointed to an apparent process of osseointegration. The reason of incorrect implants integration was probably mechanical overload or poor hygiene habits, smoking and periodontal disease – periimplantitis.

Opis:
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.
