“…However, metals have limitations related to corrosion, which can lead to toxicity or hypersensitivity reactions. Polymers are also widely used thanks to their full range of compositions, properties and shapes, in the form of matrixes, fibres, films and gels [10,11]. Their processing possibilities enable the fabrication of complex forms and structures.…”

“…An in vitro study reported that a graphene coating on a Co-Cr alloy enhanced its bioactivity [30]. Also in medical field, the study of surface modification by applying magnetic nanoparticles demonstrated that it could enhance sensitivity and stability of biosensors [31]. Since there were no significant differences in surface roughness between all the disks and no additional surface treatment was done to the disk, the present study was able to demonstrate biocompatibility of the alloys themselves fabricated with different methods with no other variables.…”

Recently, the selective laser melting (SLM) method of manufacturing three dimensional (3D) dental prosthetics by applying a laser to metal powder has been widely used in the field of dentistry. This study investigated human adipose derived stem cell (hADSC) behavior on a 3D printed cobalt-chrome (Co-Cr) alloy and its surface characteristics and compared them those of a nickel-chrome (Ni-Cr) alloy. Alloys were divided into four groups according to the material and manufacturing methods. Co-Cr disks were manufactured with three different methods: a conventional casting method, a metal milling method, and an SLM method. Ni-Cr disks were manufactured with a conventional casting method. The surface roughness and compositions of the disks were assessed. hADSCs were then cultured on the disks. Cell morphologies on the disks were analyzed by a field emission scanning electron microscope (FE-SEM). Cell proliferation was assessed with a bromodeoxyuridine (BrdU) assay kit. Cell viability was evaluated with a water-soluble tetrazolium salt (WST) assay kit. There were no differences in surface roughness between all groups. The cells were well attached to the disks, and morphologies of the cells were similar. The cell proliferation and viability of the Ni-Cr disks were significantly lower than the other groups. However, the Co-Cr disks showed no differences in their different fabricating methods. In conclusion, the biocompatibility of 3D printed Co-Cr alloys showed comparable results compared to that of the conventional casting method, and these alloys were more biocompatible than Ni-Cr alloys.

“…MCG conforms to a vectorial relation, which can provide information according to three-dimensional cardiac magnetic activity. It generally takes the component perpendicular to the chest [13][14][15][16]. Unlike ECG, MCG has little interaction with the skin, and it is not necessary to have a reference.…”
