Recently, three-dimensional structured ceramic composites with large threshold strengths (i.e., stress below which there is zero probability of failure) have been fabricated utilizing an architecture consisting of relatively stress-free, elongated prismatic domains, separated by thin compressive walls. We build upon prior work on laminate architectures, with the common feature that these struct...

The objectives of this study were to test the fracture strength in vitro laminate veneers, partial veneers and composite restorations after aging analyze failure mode. Forty extracted, sound human teeth selected divided into four groups: 1) Control group (CG); 2) Conventional Laminate Veneer (CLV); 3) Partial (PLV); 4) Direct Composite Resin (DCR). veneer preparations with incisal overlap made ...

INTRODUCTION CAD/CAM (computer-aided design and computer-aided manufacturing) systems have refreshed the idea of chair-side production of restorations, but the fracture of ceramic veneers remains a problem. Cementation with glass fibers may improve the fracture strengths and affect the failure modes of CAD/CAM-generated ceramic veneers. Therefore, this study compared the fracture strengths of c...

The widespread adoption of photovoltaics (PV) in architecture as a source of renewable energy is often limited due to poor visual acceptance. We propose the use of coloured frontglass manufactured by digital ceramic printing to cover the PV cells, thus concealing the latter while admitting sufficient light to produce electricity. The apparent colour of the PV laminate is a combination of the tr...

Multiple interdisciplinary approaches are necessary to resolve esthetic defects, espec...

The esthetic success of a dental treatment depends on the correct diagnosis, treatment plan and clinical and laboratory procedures. This clinical report describes a diagnostically based protocol for conservative preparations on anterior teeth for adhesively retained composite and porcelain restorations. The diagnostic additive wax-up, periodontal esthetic crown-lengthening, direct acrylic mock-...
