CaptekTM (Precious Chemical USA Inc., Apopka, Florida) is a new, innovative development in dental materials. It is a dental alloy that can be defined as a composite material because it is internally composed of two different alloys. CaptekTM is a high gold content alloy (88% by weight) and is used in porcelain-fused-to-metal dental crowns and bridges. Composite metals containing metallic matrix...

Most of the metal additive manufacturing technologies are focused on high cost and high end applications. There is in need, a low cost additive manufacturing technology suitable for low and high end metallic applications. Robotic automated welding can be considered as an alternative to manufactured large scale metal parts with layer by layer approach. However, many obstacles have to be overcome...

The oxy-acetylene torch brazing of copper tubes using silver-based filler metals (Ag-Cu-Zn-Cd) was investigated in this study. Filler containing silver content 15% and 35%, designated by BR15 BR35, were used to assess the influence microstructure mechanical performance brazed joints. joints analyzed means optical microscopy, scanning electron energy-dispersive spectroscopy. microstructures BR35...

INTRODUCTION In esthetic treatments with dermal fillers, increasing numbers of physicians are using the technique of mixing an anesthetic agent into the dermal filler before treatment to increase the comfort of the patients. This study aimed at evaluating the effects on the physical properties of a polycaprolactone (PCL)-based dermal filler after mixing with lidocaine. METHODS A range of 2.0%...
