“…The feldspathic ceramic-Au-Pd alloy combination presented statistically higher mean values than those of the other two low-fusing ceramic (Super Porcelain Ti-22 and Vita Titankeramik)-cpTi combinations. This finding is in agreement with several other studies [17,20,27] where also better outcomes were observed with utilization of noble alloys compared to other alloys. Interestingly however, Triceram-cpTi combination presented non-significant results from the ceramic-Au-Pd combination in non-aged conditions.…”

“…Several authors considered the shear test as the most adequate method to measure bond between the metal and ceramics [2,8,11,26,31,32]. However other authors [10,12,17,20,33,34] suggest the threepoint-flexure test, four-point-flexure test [28] or biaxial flexure test [1]. The shear test used was highly reliable, because it is based on minimal experimental variables and creates less residual stress at metal-ceramic interface, where the oblique forces are also minimized.…”

“…These tests can be classified according to the nature of the applied stresses such as shear, tensile, flexural strength or torsion tests. Unfortunately there is still no consensus as to which method is more valid for clinical implications [17]. In addition, these methods often do not involve the fatigue component of mechanical tests and thereby the results remain optimistic to a certain extent.…”

“…Although various types of tests have been described in the literature to evaluate metal-ceramic bond strength (20), there is no methodology capable of directly measuring the shear forces along the metal/ceramic interface (21), since the specimens have residual thermal stresses at the interface due to a mismatch of the CTE of ceramic and metal (23). Considering the methodology of the present study, there was a predominance of mixed failures in the groups P700 and U700, while adhesive failures were more noted in groups P400 and U400 (Table 4).…”

“…Several tests have been designed and selected by researchers to evaluate the metal-ceramic bond strength (20,21). ISO standard 9693:1999/Amd.1:2005 employs a 3-point bending test and the minimum acceptable bond strength with this test is 25 MPa (22).…”

This study evaluated the casting accuracy of crown margins and metal-ceramic shear bond strength (SBS) of pure titanium injected into casting molds made using 2 investment types at 3 mold temperatures. Sixty crown (30-degree beveled finish line) and 60 cylinder (5 mm diameter x 8 mm high) patterns were divided into 6 groups (n=10), and cast using a phosphate-bonded investment (P) and a magnesium oxide-bonded investment (U), at 400°C (groups P400 and U400), 550°C (groups P550 and U550) and 700°C (groups P700 and U700) mold temperatures. Crown margins were recorded in impression material, the degree of marginal rounding was measured and margin length deficiencies (µm) were calculated. Titanium-ceramic specimens were prepared using Triceram ceramic (2 mm high) and SBS was tested. Failure modes were assessed by optical microscopy. Data were subjected to two-way ANOVA and Tukey's HSD test (α=0.05). For casting accuracy, expressed by marginal deficiency (µm), investment U provided more accurate results (64 ± 11) than P (81 ± 23) (p<0.001). The increase in temperature resulted in different effects for the tested investments (p<0.001), as it provided better casting accuracy for U700 (55 ± 7) and worse for P700 (109 ± 18). Casting accuracy at 700°C (82 ± 31) was significantly different from 400°C (69 ± 9) and 550°C (68 ± 9) (p<0.05). For SBS, there was no significant differences among the groups for factors investment (p=0.062) and temperature (p=0.224), or for their interaction (p=0.149). Investment U provided better casting accuracy than investment P. The SBS was similar for all combinations of investments and temperatures.

Bonding of ceramic to the alloy is essential for the longevity of porcelain fused to metal restorations. Imported alloys used now a days in processing them are not economical. So this study was conducted to evaluate and compare the bond strength of ceramic material to nickel based cost effective Nonferrous Materials Technology Development Center (NFTDC), Hyderabad and Heraenium S, Heraeus Kulzer alloy. An Instron testing machine, which has three-point loading system for the application of load onto the specimen was utilized for analyzing bond strength of both alloys. Student t test was conducted and t value obtained was 0.644, and the mean value of flexural bond strength of indigenous alloy is 81.75 with standard deviation of 12.25 and of imported alloy is 84.42 with standard deviation of 10.35, indicating that there was no significant difference between the two alloys. Due to ever increasing cost of imported non-precious alloy the need for a cost-effective replacement was fulfilled by indigenous NFTDC alloy.
