“…Therefore, any surgical or dental instrument or equipment made from medical stainless steel can be exposed to acid-alkaline media. It is well known that the crevice corrosion may be a reason of destruction of steels workpieces [10]. For instance, austenitic steels 316 and 316L possess high corrosion resistance in seawater.…”

Pitting and crevice corrosion resistance of 321 stainless steel and non-vacuum electron-beam cladded stainless steel have been investigated by using potentio-dynamic polarization curve plotting. Lock-Ringer Salt Solution (LRSS) was used as biological media for corrosion test measurements. Microstructural research of samples after corrosion was carried out by using scanning electron microscopy. The experimental results show that the cladded stainless steel possesses higher pitting and crevice corrosion resistance.

“…Moreover, it has excellent biocompatibility, thus high chance of acceptance by the human body. XCT is since long being used in the medical field, be it to create detailed cross-section images of the human body that can aid the diagnostic of infections, identify masses, tumors, etc., or to aid in the design of customized medical implants such as mandible implants [6], chin implants [9], for the reconstruction of damaged jawbone [10], for cranial implants [11], etc. These customized free form implants impose a challenge when it comes to quality control since not all features are accessible by traditional contact or contactless measurement techniques, such as tactile coordinate measuring machines (tactile CMM) and laser line scanners (LLS), especially when it comes to hidden features.…”

Computed tomography: a powerful imaging technique in the fields of dimensional metrology and quality control

X-ray computed tomography (CT) is slowly conquering its space in the manufacturing industry for dimensional metrology and quality control purposes. The main advantage is its non-invasive and non-destructive character. Currently, CT is the only measurement technique that allows full 3D visualization of both inner and outer features of an object through a contactless probing system. Using hundreds of radiographs, acquired while rotating the object, a 3D representation is generated and dimensions can be verified. In this research, this non-contact technique was used for the inspection of assembled components. A dental cast model with 8 implants, connected by a screwed retained bar made of titanium. The retained bar includes a mating interface connection that should ensure a perfect fitting without residual stresses when the connection is fixed with screws. CT was used to inspect the mating interfaces between these two components. Gaps at the connections can lead to bacterial growth and potential inconvenience for the patient who would have to face a new surgery to replace his/hers prosthesis. With the aid of CT, flaws in the design or manufacturing process that could lead to gaps at the connections could be assessed.
