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 cleaned with TCE (CT), casting

and not cleaned with TCE (C), additively manufactured and

cleaned with TCE (AT), additively manufactured and not cleaned

with TCE (A). Ceramic (h=4 mm, r=6 mm) was applied to the

disc specimens (n=20) and their shear bond strength (SBS)

was measured. The surface morphology of disc (n=1; for each

subgroup) specimens before and after TCE application was

analyzed with a scanning electron microscope (SEM). Results

were statistically analyzed with 1-way ANOVA and the

Bonferroni multiple comparisons tests (α=0.05). Significant

differences were found in SBS of the CT, C, AT, and A groups.

CT group (21.74±1.66 MPa) showed a significantly higher SBS

value than the C (18.65±2.11 MPa), AT (19.07±1.75 MPa) and

A (18.52±1.94 MPa) groups (p<0.001). In conclusion the

application of the TCE increased the metal-ceramic bond of

casting Co-Cr alloy. Although the results were not statistically

significant the TCE also increased the bond of additively

manufactured Co-Cr alloy.

Özet

Çalışmanın amacı trikloroetilenin (TCE) eklemeli ve döküm

yöntemleri ile üretilen Co-Cr alaşımlarının metal-seramik

arasındaki bağlanmaya olan etkisinin araştırılmasıdır. Bu

amaçla, Co-Cr alaşımı kullanılarak döküm ve eklemeli üretim

teknikleri ile iki deney grubu (n=42) için 84 adet disk şeklinde

(12 mm çapında, 1 mm kalınlığında) örnek elde edildi. Seramik

uygulamasına başlamadan önce örnekler iki alt gruba (n=21)

ayrıldı: Döküm yöntemi ile üretilip TCE ile temizlenen (CT),

döküm yöntemi ile üretilip TCE ile temizlenmeyen (C), eklemeli

yöntem ile üretilip TCE ile temizlenen (AT) ve eklemeli yöntem

ile üretilip TCE ile temizlenmeyen (A). Sonrasında örneklere

(n=20) seramik (h=4 mm, r=6 mm), uygulanıp makaslama

bağlanma direnci testi (shear bond strength, SBS) yapıldı.

Örnek (n=1; her bir alt grup için) yüzeylerindeki TCE

uygulaması öncesi ve sonrası değişim taramalı elektron

mikroskobu (SEM) ile incelendi. Sonuçlar istatistiksel olarak 1-

way ANOVA ve Bonferroni Çoklu karşılaştırma testleri ile

değerlendirildi (α=0.05). CT, C, AT ve A gruplarının SBS

değerleri arasında istatistiksel olarak anlamlı farklılıklar

bulundu. CT grubunun (21.74±1.66 MPa) SBS değeri, diğer

gruplara göre; C (18.65±2.11 MPa), AT (19.07±1.75 MPa), A

(18.52±1.94 MPa) anlamlı derecede yüksek bulundu

(p<0.001). Sonuç olarak, TCE uygulaması döküm Co-Cr

alaşımlarının metal seramik bağlantısını önemli derecede

arttırmıştır. İstatistiksel olarak anlamlı olmamakla beraber, TCE

uygulaması sonrası eklemeli imalat yöntemi ile üretilen Co-Cr

alaşımlarının metal seramik bağlanma direnci de artmıştır.

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 study. The porcelain (IPS d.Sign porcelain system) portion of the cylindrical metal-ceramic specimens was 4 mm thick and 4 mm high; the metal portion was machined to 4x4 mm, with a base that was 5 mm thick and 1 mm high. Forty-four specimens were prepared (n=11). Ten specimens from each group were subjected to a shear load on a universal testing machine using a 1 mm/min crosshead speed. One specimen from each group was observed with a scanning electron microscope. Stress at failure (MPa) was determined. The data were analyzed with a 1-way analysis of variance (alpha=.05). The groups, all including IPS d.Sign porcelain, presented the following mean bond strengths (+/-SD) in MPa: 4 ALL, 54.0+/-20.0; Wiron, 63.0+/-13.5; IPS d.SIGN 20, 71.7+/-19.2; Argeloy NP, 55.2+/-13.5. No significant differences were found among the shear bond strength values for the metal-ceramic specimens tested. None of the base metal alloys studied demonstrated superior bond strength to the porcelain tested.

Uses of and Exposure to Trichloroethylene in U.S. Industry: A Systematic Literature Review

Article

Full-text available

Jun 2007

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 by reviewing the reference lists from the identified literature. The collected information was systematized by the Standard Industrial Classification (SIC) system, and measurement data reported in the literature were summarized in a database. TCE use was extensive from the early 1920s through the 1970s mainly as a degreasing agent in metal-fabricating operations. After the 1970s it became less popular because of environmental concerns. TCE historically has had a multitude of uses in many other industries, e.g., dry cleaning, textile, electronics, leather, and rubber. Also, many products like adhesives, drugs, paints, inks, and various industrial products have contained TCE. It was banned as a food additive and in cosmetics in 1977. The arithmetic mean (AM) of the measurements across all industries and decades was 38.2 ppm. The highest personal and area air levels were reported in vapor degreasing (AM of 44.6 ppm). Most TCE measurements were performed in the 1950s, 1970s, and 1980s. The data described here could be used by exposure assessors as is to identify the presence and approximate levels of exposure. Using the same information as a basis should increase the reliability of the assessments, making it easier to compare both the exposure assessment methods and the epidemiologic results across different studies.

Performance investigation of Zeolitic Imidazolate Framework – 8 (ZIF-8) in the removal of trichloroethylene from aqueous solutions

Article

Aug 2019

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 was measured using the GC-Mass. The removal rate of trichloroethylene increased with increasing contact time and adsorbent dosage while it decreased after an increase in pH and initial concentration of trichloroethylene. The best pH and adsorbent dose for the removal of trichloroethylene was 7.5 and 0.313 g/L, respectively. The optimum removal efficiency for TCE removal by ZIF-8 adsorbent was 96.29%. Kinetic studies showed that adsorption of TCE by ZIF-8 follows a pseudo second order. Langmuir isotherm with an R² of 0.9926 for TCE was the best graph for the experimental data. The maximum adsorption capacity was 136.33 mg/g. The results showed that ZIF-8 adsorbent could be effective in removal of trichloroethylene from aqueous solution.

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, mechanical properties, surface roughness and contact angle. The bond strength of the metal–ceramic system, with and without TiSiN interlayers, was evaluated by using a three-point bending test. The coatings consisted of nanocrystalline solid solutions (grain sizes of 3.6–4.3 nm) with a face-centered cubic structure. The film hardness, ranging from approximately 21 to 38 GPa, was observed to increase with increasing substrate bias, irrespective of the substrate type. The best adhesion values (critical loads of ~54 N) were obtained on both substrates for coatings deposited at of −100 V bias voltage. The deposition of the TiSiN coatings determined the roughness decrease of both NiCr and CoCr coated alloys. The contact angle measurements indicated a hydrophobic character for the films deposited at bias voltages ranging from −50 to −150 V and a hydrophilic character at a bias of −200 V. The results indicated that TiSiN coatings improved the bond strength of NiCr – ceramic systems. Based on these results it is expected an increase of the clinical service life of the dental restorations having a TiSiN interlayer between the metallic support and the ceramic layer.

Evaluation of the mechanical properties and porcelain bond strength of cobalt-chromium dental alloy fabricated by selective laser melting

Article

Oct 2013

Limited information is available regarding the microstructure and mechanical properties of dental alloy fabricated by selective laser melting (SLM). 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. Five metal specimens and 10 metal ceramic specimens were fabricated to evaluate the mechanical properties of SLM Co-Cr dental alloy (SLM alloy) with a tensile test and its porcelain bond strength with a 3-point bending test. The relevant properties of the SLM alloy were compared with those of the currently used Co-Cr dental alloy fabricated with conventional cast technology (cast alloy). The Student t test was used to compare the results of the SLM alloy and the cast alloy (α=.05). The microstructure of the SLM alloy was analyzed with a metallographic microscope; the metal ceramic interface of the SLM porcelain bonded alloy was studied with scanning electron microscopy, energy dispersive x-ray spectroscopy, and an electron probe microanalyzer. Both the mean (standard deviation) yield strength (884.37 ±8.96 MPa) and tensile strength (1307.50 ±10.65 MPa) of the SLM alloy were notably higher than yield strength (568.10 ±30.94 MPa) and tensile strength (758.73 ±25.85 MPa) of the currently used cast alloy, and the differences were significant (P<.05). The porcelain bond strength of the SLM alloy was 55.78±3.02 MPa, which was similar to that of the cast alloy, 54.17±4.96 MPa (P>.05). Microstructure analysis suggested that the SLM alloy had a dense and obviously orientated microstructure, which led to excellent mechanical properties. Analysis from scanning electron microscopy, energy dispersive x-ray spectroscopy, and the electron probe microanalyzer indicated that the SLM alloy had an intermediate layer with elemental interpenetration between the alloy and the porcelain, which resulted in an improved bonding interface. Compared with the currently used cast alloy, SLM alloy possessed improved mechanical properties and similar porcelain bond strength.

Influence of Surface Treatment on the Shear Bond Strength of Ceramics Fused to Cobalt-Chromium

Article

Feb 2010

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); and Gr4: Duceram + W. The specimens were aged using thermal cycling (3000x, 5 to 55 degrees C, dwell time: 30 seconds, transfer time: 2 seconds). The shear test was performed with a universal testing machine, using a load cell of 100 kg (speed: 0.5 mm/min) and a specific device. The bond strength data were analyzed using ANOVA and Tukey's test (5%), and the failure modes were analyzed using an optical microscope (30x). The means and standard deviations of the shear bond strengths were (MPa): G1 (57.97 +/- 11.34); G2 (40.62 +/- 12.96); G3 (47.09 +/- 13.19); and G4 (36.80 +/- 8.86). Ceramic (p= 0.03252) and surface treatment (p= 0.0002) significantly affected the mean bond strength values. Air-particle abrasion with Al(2)O(3) improved the shear bond strength between metal and ceramics used.
