“…PCCs are used in prosthetics for several reasons such as the possibility of obtaining very good aesthetic effects for prosthetic restorations and the approximation of mechanical properties, including abrasion to human enamel [ 18 , 19 ]. Composite materials of this class are dedicated to both CAD/CAM and additive manufacturing systems [ 19 , 20 ].…”

“…Therefore, they still represent an area for development. Krishnakumar and Senthilvelan mention new PCCs that are suitable for the manufacture of fixed prostheses, i.e., bridges and crowns, including full dental arches, due to their appropriate mechanical properties [ 18 ]. Those suitable PCCs include CF/PMMA, UHMWPE/PMMA, and GF/PMMA [ 18 ].…”

Alumina and Zirconia-Reinforced Polyamide PA-12 Composites for Biomedical Additive Manufacturing

et al. 2021

This work aimed to prepare a composite with a polyamide (PA) matrix and surface-modified ZrO2 or Al2O3 to be used as ceramic fillers (CFs). Those composites contained 30 wt.% ceramic powder to 70 wt.% polymer. Possible applications for this type of composite include bioengineering applications especially in the fields of dental prosthetics and orthopaedics. The ceramic fillers were subjected to chemical surface modification with Piranha Solution and suspension in 10 M sodium hydroxide and Si3N4 to achieve the highest possible surface development and to introduce additional functional groups. This was to improve the bonding between the CFs and the polymer matrix. Both CFs were examined for particle size distribution (PSD), functional groups (FTIR), chemical composition (XPS), phase composition (XRD), and morphology and chemical composition (SEM/EDS). Filaments were created from the powders prepared in this way and were then used for 3D FDM printing. Samples were subjected to mechanical tests (tensility, hardness) and soaking tests in a high-pressure autoclave in artificial saliva for 14, 21, and 29 days.

“…The most important polymers that are used in orthopedic implantology are: polymethylmethacrylate (PMMA), silicone rubber, polyethylene (PE), and polyamide (PA) [ 11 , 12 , 13 , 14 ]. They are used mainly as “inserts” as the acetabular liner for the orthopedic hip replacement.…”

Selective Laser Sintering of PA 2200 for Hip Implant Applications: Finite Element Analysis, Process Optimization, Morphological and Mechanical Characterization

et al. 2021

Polyamide 12 (PA 22000) is a well-known material and one of the most biocompatible materials tested and used to manufacture customized medical implants by selective laser sintering technology. To optimize the implants, several research activities were considered, starting with the design and manufacture of test samples made of PA 2200 by selective laser sintering (SLS) technology, with different processing parameters and part orientations. The obtained samples were subjected to compression tests and later to SEM analyses of the fractured zones, in which we determined the microstructural properties of the analyzed samples. Finally, an evaluation of the surface roughness of the material and the possibility of improving the surface roughness of the realized parts using finite element analysis to determine the optimum contact pressure between the component made of PA 2200 by SLS and the component made of TiAl6V4 by SLM was performed.

“…Consequently, it is Previous studies have demonstrated that grinding and drilling were the principal dental procedures that caused the release of a significant amount of particles in the air. 20,53,55 Specifically, Bradna et al 59 verified that grinding produces particles at two size modes, in nano-and microparticles. In agreement with literature findings, particle generation in the treatment room was associated inherently with dental procedures.…”

Airborne particles and microorganisms in a dental clinic: Variability of indoor concentrations, impact of dental procedures, and personal exposure during everyday practice

Studying air quality in healthcare facilities comprises of identification of the contaminant sources, their dispersion, and impact on indoor air. 1,2 Considering as ultimate purpose pathogen mitigation, minimization of the acquired infections both for the patients and the personnel is a challenging issue, 3,4 not only because of the direct contact with the contaminant sources but also due to their great variability in their characteristics and properties.Airborne particulate contaminants consist mainly of aerosols and/or particles of biological matter, that is, bioaerosols. Airborne aerosol properties vary considerably depending on their size and chemical/biological composition. 5 In turn, their size and composition are governed by their origin (natural environment, anthropogenic
