Evaluation the Effect of Trichloroethylene on the Metal-Ceramic Bonding
Abstract
The aim of the study is to evaluate the effect of trichloroethylene (TCE) on the metal-ceramic bond of additively manufactured and casting Co-Cr alloys. For this purpose, 84 disc-shaped (r=12 mm, h=1 mm) specimens were prepared for two experimental groups (n=42) with different fabrication techniques; casting and additively manufactured with Co-Cr. Before ceramic application, the disc specimens divided into two subgroups (n=21): Casting and...

Statement of problem Limited information is available regarding the microstructure and mechanical properties of dental alloy fabricated by selective laser melting (SLM). Purpose The purpose of this study was to evaluate the mechanical properties of a cobalt-chromium (Co-Cr) dental alloy fabricated by SLM and to determine the correlation between its microstructure and mechanical properties and its porcelain bond strength. Material and methods Five metal specimens and 10 metal ceramic specimens we...
Review paper
S everal years ago porcelain-fused-to-gold (PFG) restorations were introduced to fixed partial denture prosthodontics. The new materials and related clinical techniques represent an important step toward an optimal solution to many problems in fixed prosthodontics, especially in the anterior region. The method combines the esthetic qualities of porcelain with the strength, accuracy, and marginal adaptation of the metal. Several studies have been published on the clinical and material aspects of ...

The success of metal-ceramic restorations is influenced by the compatibility between base metal alloys and porcelains. Although porcelain manufacturers recommend their own metal systems as the most compatible for fabricating metal-ceramic prostheses, a number of alloys have been used. Purpose This study evaluated the shear bond strength between a porcelain system and 4 alternative alloys.Two Ni-Cr alloys: 4 ALL and Wiron 99, and 2 Co-Cr alloys: IPS d.SIGN 20 and Argeloy NP were selected for this...

Statement of problem Different combinations of Co-Cr alloys bonded to ceramic have been used in dentistry; however, the bond strength of ceramic to metal can vary because of different compositions of these alloys. Purpose The purpose of this study was to evaluate the shear bond strength of a dental ceramic to 5 commercially available Co-Cr alloys. Material and methods Five Co-Cr alloys (IPS d.SIGN 20, IPS d.SIGN 30, Remanium 2000, Heranium P, and Wirobond C) were tested and compared to a control...

This article describes a systematic review of the industrial hygiene literature for uses of trichloroethylene (TCE) in industry for the exposure assessment of two population-based case control studies of brain cancer in the United States. Papers and reports that address uses of and exposures to TCE were identified from MEDLINE, TOXLINE, NIOSHTIC, the NIOSH Health Hazard Evaluation database (keywords: chlorinated solvents and trichloroethylene), and in other reviews. This search was complemented ...

Objectives: The purpose of this study was to compare the microstructure, hardness, corrosion resistance and metal–porcelain bond strength of a CoCrMo dental alloy obtained by two routes, cast and hot pressing. Methods: CoCrMo alloy substrates were obtained by casting and hot pressing. Substrates' microstructure was examined by the means of Optical Microscopy (OM) and by Scanning Electron Microscope (SEM) and Energy Dispersive X-ray Spectroscopy (EDS). Hardness tests were performed in a microhard...

To evaluate the influence of surface treatment on the shear bond strength between a Co-Cr alloy and two ceramics.Forty-eight metal cylinders were made (thickness: 4 mm, height: 3.7 mm) according ISO TR 11405. The 48 metallic cylinders were divided into four groups (n = 12), according to the veneering ceramic (StarLight Ceram and Duceram Kiss) and surface treatments: air-particle abrasion with Al(2)O(3) or tungsten drill (W). Gr1: StarLight + Al(2)O(3); Gr2: StarLight + W; Gr3: Duceram + Al(2)O(3...

The presence of trichloroethylene in the groundwater has caused major concerns on a global scale. In this study, the effect of different parameters such as contact time (15–120 min), pH (3–12), adsorbent dose (0.05–0.35 g/L), and the initial concentration of TCE (5–50 μg/L) was studied. The structure of the adsorbent was determined by XRD, SEM, FT-IR, BET, and TEM. In this study, Freundlich and Langmuir isotherm models were used to calculate the equilibrium constants. Residual Trichloroethylene ...

The aim of the study was to evaluate the effect of annealing on the nanostructure and hardness of Co-Cr metal ceramic samples that were fabricated with a direct metal laser sintering (DMLS) technique.Five groups of Co-Cr dental alloy samples were manufactured in a rectangular form measuring 4 × 2 × 2 mm. Samples fabricated by a conventional casting technique (Group I) and prefabricated milling blanks (Group II) were examined as conventional technique groups. The DMLS samples were randomly divide...

High bonding between the NiCr or CoCr alloys and the ceramic layer is essential for the clinical success of dental prostheses restorations. Aiming to enhance the bond strength between metal and dental ceramics in prosthetic restorations, TiSiN coatings were deposited as interlayers. The coatings were deposited on NiCr and CoCr dental alloys by using the cathodic arc technique at various substrate bias voltage values and characterized in terms of elemental composition, crystalline structure, mech...
