The purpose of this study was to evaluate the effect of different surface treatments of yttria-stabilized tetragonal zirconia (Y-TZP) on bond strength durability and marginal discrepancies. For adhesion testing, 144 specimens of VITA In-Ceram YZ ceramic for InLab were obtained (5.25×3.75×4.5 mm) and divided into six groups (n=24) according to the surface treatment: 1) Control (CRTL): untreated;...

Ceramics are a very popular material in dental implant technology due to their tribological properties, their biocompatibility and their esthetic appearance. However, their natural surface structure lacks the ability of proper osseointegration, which constitutes a crucial process for the stability and, thus, the functionality of a bone implant. We investigated the application of a glass solder ...

Ceramic materials show excellent esthetic behavior, along with an absence of hypersensitivity, making them a possible alternative implant material in dental surgery. However, their surface properties enable only limited osseointegration compared to titanium implants. Within this study, a novel surface coating technique for enhanced osseointegration was investigated biologically and mechanically...

Pseudomonas aeruginosa causes severe nosocomial pneumonia in Intensive Care Unit (ICU) patients, with an increased prevalence of multiresistant strains. We examined the impact of the use of antipseudomonal antibiotic(s) on the susceptibility of P. aeruginosa isolated from ICU patients with clinically suspected hospital-acquired pneumonia collected in five teaching hospitals (110 non-duplicate i...

The improvement of high temperature materials with lower heat transfer coefficients lead to the development thermal barrier coatings (TBCs). One most widely used for is Y2O3 stabilized ZrO2 (Y-TZP) because its excellent shock resistance, low conductivity, and relatively coefficient expansion. aim this work study TBCs mechanical behavior addition SiC into suspension Y-TZP/Al2O3 by acoustic emiss...

Herein, for the first time is described design of a novel porous zirconia scaffolds manufactured by using polymer-infiltrated ceramic network (PICN) and 3D-printing technologies. Cubic geometry pieces was obtained perpendicular layer-by-layer deposition yttrium-stabilized tetragonal polycrystal (3Y-TZP) Pluronic® hydrogel paste. The specimens were prepared robocasting assembly with 50% infill p...
