CaptekTM (capillary technology) is an advanced metallurgic system that was developed to combine optimal natural esthetics of dental porcelain with the strength of ceramometal , to produce accurate restorations on all types of tooth preparation and provide a biocompatible environment for the oral tissues in simple and affordable procedures. CaptekTM restorations include inlays, onlays, crowns, a...

Nanocomposite thin films comprised of metastable metal carbides in a carbon matrix have a wide variety of applications ranging from hard coatings to magnetics and energy storage and conversion. While their deposition using nonequilibrium techniques is established, the understanding of the dynamic evolution of such metastable nanocomposites under thermal equilibrium conditions at elevated temper...

The nose is one of the most important cosmetic units of the face. Discreet variations in the nose shape lead to marked physiognomy changes. Many patients dissatisfied with the appearance of their nose seek cosmetic improvement as early as during adolescence. Similar to other facial structures, the nose is affected by the aging process. Typically, nose tip drop is observed, along with loss of su...

Superior sulcus filler injection is a nonsurgical method to rejuvenate the upper face. Blindness and stroke are devastating complications of facial filler injection. This study describes an injection technique that minimizes the risk of blindness and includes a case study demonstrating the cosmetic benefits of this procedure. To avoid retrograde injection of filler embolus into the ophthalmic a...

In this study, the interaction between the silica filler and polydimethylsiloxanes (PDMS) was investigated from the aspects of the bound rubber and morphological characterization. With special attention to the dynamic properties, the dynamic test was conducted by dynamic shear rheometer. The results show that the modified fillers disperse uniformly within PDMS matrix without aggregation and con...

Digital radiography was used to measure the radiopacity of 18 resin cements to determine the influence of inorganic filler content on radiopacity. Four disk specimens (n=4) of each light-curing cement were digitally radiographed alongside an aluminum step wedge using an intraoral sensor (XIOS Plus, Sirona, Germany), and their mean gray value measured. Percentage of filler by weight was determin...

Performing rhinoplasty using filler injections, which improve facial wrinkles or soft tissues, is relatively inexpensive. However, intravascular filler injections can cause severe complications, such as skin necrosis and visual loss. We describe a case of blepharoptosis and skin necrosis caused by augmentation rhinoplasty and we discuss the patient's clinical progress. We describe the case of a...

BACKGROUND The combination of different injectable fillers in one area is considered to increase the risk of adverse reactions. OBJECTIVES To characterize adverse reactions in patients who received more than one filler in the same facial region. METHODS Data (up to July 2009) of the Injectable Filler Safety Study, a German-based registry for adverse filler reactions, was analysed descriptiv...

INTRODUCTION The aim of this in-vitro study was to investigate the effect of the filler-volume fraction of experimental composite adhesives on the bacterial adhesion of Streptococcus mutans. METHODS Three experimental adhesive groups were created: an unfilled urethane-dimethacrylate (UDMA) adhesive, UDMA and a filler-volume fraction of 35%, and UDMA and a filler-volume fraction of 70%. The em...

Lime sludge is a special type of precipitated calcium carbonate (PCC) recovered from black liquor, which can be used as paper filler in the paper-making process. However, one of the biggest problems when lime sludge is used as filler is that it is difficult to hydrophobically size the filled paper, especially in the case of paper with high filler content. Also, the efficient retention of the si...
