OBJECTIVES Our study aimed to examine not only the incidence but also the impact of noise from two types of total hip replacement articulations: ceramic-on-ceramic and ceramic-on-polyethylene. METHODS We performed a case-controlled study comparing subjective and objective questionnaire scores of patients receiving a ceramic-on-ceramic or a ceramic-on-polyethylene total hip replacement by a si...

STATEMENT OF PROBLEM Evidence is limited on the efficacy of zirconia-based fixed dental prostheses. OBJECTIVE To carry out a literature review of the behavior of zirconium oxide dental restorations. MATERIAL AND METHODS This literature review searched the Pubmed, Scopus, Medline and Cochrane Library databases using key search words "zirconium oxide," "zirconia," "non-metal restorations," "c...

Adhesion failure and/or detachment of ceramic tiling are common building defects. Bonding rupture of this type of coating presents a serious risk to people’s safety, in particular if it occurs on external façades. It may be avoided by earlier non-destructive inspections. This paper presents the results of an active thermography investigation in which adhesive bonding defects of ceramic coatings...

Introduction: The purpose of the presented study was to evaluate the effect of zirconia thickness on the tensile stress of zirconia based all-ceramic restorations. Methods: Twenty zirconia disks with 10mm diameter were prepared in two groups using CAD/CAM system. The thickness of zirconia was 0.5mm in first group and 0.3mm in second group. After sintering, 0.4mm glass ceramic porcelain was appl...

We present a case of a 71-year-old woman with unexplained instability of her total hip arthroplasty 12 years after implantation due to loosening of the ceramic component of a sandwich ceramic in polyethylene liner. She experienced in total 2 dislocations in 6 months. These events occurred without fracture of the ceramic liner. Sandwich ceramic liners were introduced with the idea of combining t...

AIMS/BACKGROUND The objective of this review was to define the impact of cementation mode on the longevity of different types of single tooth restorations and fixed dental prostheses (FDP). METHODS Literature search by PubMed as the major database was used utilizing the terms namely, adhesive techniques, all-ceramic crowns, cast-metal, cement, cementation, ceramic inlays, gold inlays, metal-c...

(2014). Customized glass sealant for ceramic substrates for high temperature electronic application. Abstract This study investigates the ceramic to ceramic bonding, using composite glass frit as the binding layer that is able to tolerate a high temperature environment for ruggedized microelectronic applications. Shear strength measurements were carried out at both ambient room and high tempera...

An important technique used for the grading of voltage drop along high voltage ceramic insulators is to provide some surface conduction to bleed off accumulated surface charge. We have used metal ion implantation to modify the surface of high voltage ceramic vacuum insulators to provide a uniform surface resistivity of order 10 Ω/square. A vacuum arc ion source based implanter was used to impla...

This work deals with modeling and simulation of SO2 removal in a ceramic membrane by means of FEM. A mass transfer model was developed to predict the performance of SO2 absorption in a chemical solvent. The model was based on solving conservation equations for gas component in the membrane. Computational fluid dynamics (CFD) of mass and momentum were used to solve the model equations. The simul...

CONTEXT Marginal discrepancy influenced by the choice of processing material used for the ceramic laminate veneers needs to be explored further for better clinical application. AIMS This study aimed to evaluate the amount of cervical and incisal marginal discrepancy associated with different ceramic laminate veneering materials. SETTINGS AND DESIGN This was an experimental, single-blinded, ...
