OBJECTIVE To evaluate the marginal gap (MG) and absolute marginal discrepancy (MD) of full ceramic crowns with two finish line designs, shoulder and chamfer, using microcomputed tomography (micro-CT) before and after cementation. MATERIALS AND METHODS Sixty extracted human maxillary premolar teeth were divided into two groups based on the finish line design: Group I: 90° shoulder and Group II...

Introduction: The marginal bone change of 1 year loading was evaluated in the non-microthread collar and platform switching structured INNO® dental implant of which the surface is treated with the RBM sandblasting, hyper-thermal acid etching and alkali solution cleaning process for hydrophilic macroand micro-porosity. Material and Methods: A total of 144 implants were placed in the healed ridge...

Aim To evaluate the influence of different manufacturing methods of single implant-supported metallic crowns on the internal and external marginal fit through computed microtomography. Methods Forty external hexagon implants were divided into 4 groups (n = 8), according to the manufacturing method: GC, conventional casting; GI, induction casting; GP, plasma casting; and GCAD, CAD/CAM machinin...

This paper describes a pioneer study on prosodic control for Cantonese text-to-speech synthesis. We attempt to establish a set of segment-level duration rules and contextdependent F0 profiles and apply them to a syllable-based concatenative speech synthesizer which uses TD-PSOLA as prosodic modification technique. The prosodic features are extracted by statistical characterization of a large am...

In restorative treatment using fixed dental prostheses, dentists should select appropriate restoration material among various types of dental materials. The strength, marginal fit, esthetics, wear resistance, biocompatibility, and cost are important factors in the choice of restoration materials. The present case showed a surface stain on a monolithic zirconia restoration that was due to wear b...

As staring focal plane array (FPA) detectors continue to mature, FPA based IR imaging systems are available in more compact packages that are lighter and consume less power than first or second generation scanning IR sensor packages. However, standard IR analysis models indicate that staring FPA based cameras, while having excellent sensitivity, will have reduced resolution when compared to sca...

-Methyl-3-(3,5-diiodo-4-carboxymethoxybenzyl)benzofuran (KB130015 or KB) is a new drug, structurally related to amiodarone and to thyroid hormones. Its effects on cardiac voltage-dependent Na+ current (I Na) were studied in pig single ventricular myocytes at 22 degrees C using the whole-cell (with [Na+]i = [Na+]o = 10 mM) and cell-attached patch-clamp techniques. KB markedly slowed I Na inactiv...
