Silica coating can improve bonding of resin to glass-infiltrated aluminum oxide ceramic (In-Ceram), and sandblasting is a pretreatment to thermal silica coating (Silicoater MD system) or a tribochemical coating process (Rocatec system). This study evaluated the effects of sandblasting and coating techniques on volume loss, surface morphology, and surface(More)
Chemerin is a chemoattractant adipokine that regulates adipogenesis and may induce insulin resistance. Chemerin serum concentrations are elevated in obese, insulin-resistant, and inflammatory states in vivo. Here we investigate the role of omental (OM) and subcutaneous (SC) adipose tissue chemerin and CMKLR1 messenger RNA (mRNA) expression in human obesity.(More)
Current ceramic materials offer preferred optical properties for highly esthetic restorations. The inherent brittleness of some ceramic materials, specific treatment modalities, and certain clinical situations require resin bonding of the completed ceramic restoration to the supporting tooth structures for long-term clinical success. This article presents a(More)
OBJECTIVE IGF-1 and the IGF-1 receptor (IGF-1R) have been implicated in the regulation of adipocyte differentiation and lipid accumulation in vitro. RESEARCH DESIGN AND METHODS To investigate the role of IGF-1 receptor in vivo, we have inactivated the Igf-1r gene in adipose tissue (IGF-1R(aP2Cre) mice) using conditional gene targeting strategies.

OBJECTIVES Failures of implant-abutment connections are relatively frequent clinical problems. The aim of this study was to evaluate the influence of long-term dynamic loading on the fracture strength of different implant-abutment connections. MATERIAL AND METHODS Six implant systems were tested: two systems with external connections (Brånemark, Compress)(More)
AIMS/HYPOTHESIS Vaspin (visceral adipose tissue-derived serpin) was first identified as an adipokine in a rat model of type 2 diabetes, in which it is predominantly secreted from visceral adipose tissue. Serum concentrations of vaspin show a food intake-related diurnal variation. We therefore tested the hypothesis that vaspin plays a role in the regulation(More)
PURPOSE To evaluate the long-term outcome of all-ceramic resin-bonded fixed dental prostheses (RBFDPs) made with a two-retainer design or a cantilever single-retainer design. MATERIALS AND METHODS Overall, 38 anterior RBFDPs were made from a glass-infiltrated alumina ceramic (In-Ceram). Sixteen RBFDPs had a two-retainer design, while 22 RBFDPs had a(More)
OBJECTIVES The purpose of this prospective study was to evaluate the clinical outcome of crown-retained fixed dental prostheses (FDPs) made from a lithium-disilicate glass-ceramic (IPS e.max Press, Ivoclar-Vivadent). METHODS Thirty-six three-unit FDPs were placed in 28 patients. The FDPs replaced teeth in the anterior (16%) and posterior (84%) regions.(More)
PURPOSE The purpose of this preliminary prospective study was to evaluate the clinical outcome of crown-retained and inlay-retained fixed partial dentures (FPDs) made from a new lithium-disilicate glass-ceramic (IPS e.max Press, Ivoclar Vivadent). MATERIALS AND METHODS Eighty-one 3-unit FPDs were placed in 68 patients. The FPDs replaced teeth in the(More)
OBJECTIVES The purpose of this in vitro study was to evaluate the effect of intaglio surface air-abrasion on the retention of CAD/CAM produced zirconia ceramic crowns cemented with three different types of cement. In addition the influence of artificial aging in masticatory simulator and thermocycling was tested. METHODS Extracted human premolars were(More)
