We report a case of aortic stenosis with porcelain aorta using an apicoaortic valved conduit after 'aortic no touch' off-pump coronary artery bypass grafting. Apicoaortic valved conduit is a good surgical option for this patient to avoid re-entry through the sternum, injury to patent graft and manipulation of the porcelain ascending aorta.

PURPOSE The purpose of this study was to assess the impact of the core materials, thickness and fabrication methods of veneering porcelain on prosthesis fracture in the porcelain fused to metal and the porcelain veneered zirconia. MATERIALS AND METHODS Forty nickel-chrome alloy cores and 40 zirconia cores were made. Half of each core group was 0.5 mm-in thickness and the other half was 1.0 mm...

PURPOSE The purpose of this study was to investigate appropriate contrast reference values (CRVs) by comparing the contrast in phantom and clinical images. MATERIALS AND METHODS Phantom contrast was measured using two methods: (1) counting the number of visible pits of different depths in an aluminum plate, and (2) obtaining the contrast-to-noise ratio (CNR) for 5 tissue-equivalent materials ...

introduction: today, the prevention of work-related musculoskeletal disorders (msds) is considered as a vital issue and one of the highest national priorities. this study was conducted with the aim of evaluating occupational postures and the prevalence of msds among porcelain industry workers of the city of rasht, iran. materials and methods: this cross-sectional study was done in 2015 on 66 wo...

The potential of a combination between single-step sintering and ZrO2 additive as a simple ceramic fabrication method to obtain dental porcelain-based ceramic-nanocomposites with good mechanical properties was demonstrated. Influences of sintering condition on phase formation, densification, microstructure and mechanical properties of these porcelain ceramics were examined via XRD, SEM-EDX and ...

Advances in the technology of bonding porcelain to enamel created the possibility of porcelain veneers as an alternative to the use of full crowns for the treatment of many clinical conditions, such as treatment of diastemas, malaligned teeth, worn dentition, chipped teeth, and excessively discolored teeth. Veneers are considered to be a more conservative treatment approach than full crowns bec...

As the distinguished representation of Chinese industrial art, blue-and-white porcelain shows the soul of Chinese traditional industrial culture. However, to combine porcelain research with symbolism theories is a process of symbolization. Firstly, the researches on blue-and-white porcelain are part of Chinese traditional industrial art and technology engineering researches while symbolism is a...

The surgical management of porcelain aorta in patients requiring aortic valve replacement or coronary artery surgery carries a high morbidity and mortality and remains controversial. We report a successful transapical aortic valve implantation in combination with on-pump coronary artery bypass grafting in a young patient with severe aortic stenosis, left main coronary artery disease and porcela...
