OBJECTIVE To determine the resistance failure value of nonprecious metal-ceramic restorations at the incisal edge with varying thickness under different application of load. MATERIALS AND METHODS An Ivorian central incisor was prepared to receive metal-ceramic crown, which was further duplicated, invested, casted and 72 metal dies were fabricated in Co-Cr alloy. Metal dies were relieved with ...

for management of a symptomatic maxillary lateral incisor with dull pain on chewing, suppurative sinus tract, defective metal-ceramic crown and iatrogenic internal root resorption, an interdisciplinary approach was taken. two-visit nonsurgical treatment with calcium-enriched mixture (cem) cement, replacement of metal-ceramic crown with all-ceramic crown and corrective periodontal plastic surger...

Unprecedented multi-channel TiN micro/nanotubes as well as various metal nitride nanofibers, including TiN, VN, NbN and ternary metal nitride nanofibers, were fabricated by a template free electrospinning method combined with post-nitridation.

INTRODUCTION The majority of current artificial hip implants use a material combination of ultra-high molecular-weight polyethylene against metal or ceramic. However, it is well documented that the wear debris from these prostheses contributes to osteolysis and ultimate failure of the prosthesis, hence alternative materials have been sought, such as metalon-metal and ceramic-on-ceramic [1]. Mor...

P(4) reaction with metal NPs (In, Pb, Zn) provides an easy access to the corresponding metal phosphide NPs in a soft and stoichiometric reaction. Size-influence on the reactivity is investigated in the case of indium.

Metal nanoparticles have received considerable attention due to their unusual properties and promising applications in electronics, photonics and biochemical sensing and imaging. This review presents an introduction to the synthesis of metal nanoparticles, especially the gold nanoparticles in shape of rod. The growth mechanism of gold nanorods and optical properties of metallic nanoparticles is...

OBJECTIVES The objective of this systematic review was to assess the 5-year survival rates and incidences of complications associated with ceramic abutments and to compare them with those of metal abutments. METHODS An electronic Medline search complemented by manual searching was conducted to identify randomized-controlled clinical trials, and prospective and retrospective studies providing ...

Recently introduced FIB/SEM analysis in microscopy seems to provide a high-resolution characterization of the samples by 3D (FIB) cross-sectioning and (SEM) high resolution imaging. The aim of this study was to apply the FIB/SEM and SEM/EDS analysis to the interfaces of a metal-ceramic vs. two zirconia-ceramic systems. Plate samples of three different prosthetic systems were prepared in the den...

PURPOSE The porcelain fused to gold has been widely used as a restoration both with the natural esthetics of the porcelain and durability and marginal fit of metal casting. However, recently, due to the continuous rise in the price of gold, an interest towards materials to replace gold alloy is getting higher. This study compared the bond strength of porcelain to millingable palladium-silver (P...
