“…There are some reports in the literature on the aluminum content of titanium after airborne-particle abrasion (1,14,17,19). However, in previous studies on various dental alloys (20), the high amount of aluminum was found after airborne-particle abrasion.…”

“…The use of titanium and its alloys for cast restorations and partial denture frameworks has increased substantially over the last years, because of their excellent biocompatibility, corrosion resistance, high strength-to-weight ratio, and low cost (1,2). Also, this trend can be mainly attributed to the development of casting technology for titanium alloys, such as new casting machines, investment materials and the extensively reported advantages of titanium over other base metal alloys (1,2).…”

“…Also, this trend can be mainly attributed to the development of casting technology for titanium alloys, such as new casting machines, investment materials and the extensively reported advantages of titanium over other base metal alloys (1,2). However, the presence of an excessive oxide layer is a possible cause of decreased bonding durability (3).…”

The aim of this study was to analyze the shear bond strength between commercially pure titanium, with and without laser welding, after airbone-particle abrasion (Al 2 O 3 ) and 2 indirect composites. Sixty-four specimens were cast and divided into 2 groups with and without laser welding. Each group was divided in 4 subgroups, related to Al 2 O 3 grain size: A -250 µm; B -180 µm; C-110 µm; and D -50 µm. Composite rings were formed around the rods and light polymerized using UniXS unit. Specimens were invested and their shear bond strength at failure was measured with a universal testing machine at a crosshead speed of 2.0 mm/min. Statistical analysis was carried out with ANOVA and Tukey's test (α=0.05). The highest bond strength means were recorded in 250 µm group without laser welding. The lowest shear bond strength means were recorded in 50 µm group with laser welding. Statistically significant differences (p<0.05) were found between all groups. In conclusion, airborne particle abrasion yielded significantly lower bond strength as the Al 2 O 3 particle size decreased. Shear bond strength decreased in the laser welded specimens.

“…Previous experiments on binding Ti with a dental ceramics in a traditional firing process revealed that different thermal expansion coefficients of these materials and the formation of oxygen layers lead to the formation of fractures [15][16]. The application of field assisted sintering technique and the gradual change in composition of the dental ceramics -Ti gradient may overcome these problems.…”

“…During the firing of porcelain on Ti at high temperature, however the chemical reaction of metal with oxygen is violent and the reaction causes to form the Ti oxides layer that thickens and apparently weaks the bonding of the interface between porcelain and Ti. [1][2][3] To alleviate the embrittled interface, Wang et al 4) deposited a Cr single layer and Cr/Cr oxide bi-layer coatings by the technique of physical vapor deposition, and the coatings served as an oxygen diffusion barrier on the Ti substrate prior to veneering of porcelain. Similarly, Sadeq et al 5) applied a thin gold coating on the surface of Ti to limit the Ti oxidation during firing cycles.…”

Porcelain veneered on pure titanium with an intermediate plasma-sprayed ZrO 2 bond coat layer was investigated in this study. The pure porcelain coating veneered on Ti was used as a control. The specimens were subjected to four-point bending test to measure the bonding strength. The fractograph, microstructure, surface roughness, and phase of plasma-sprayed ZrO 2 bond coat were examined. The phase constituents at the location of adhesive failure of the fractured specimens were investigated by thin-film X-ray diffractometry. Experimental results reveal that the bonding strength of the coating with the intermediate layer was increased by 55.7% that was accompanied by a significant decrease of the area of adhesive failure in the fracture. The ZrO 2 provided a higher surface roughness to enhance the mechanical bond at the interface of porcelain/ZrO 2 , meanwhile it acted as a sufficient oxygen diffusion barrier at 800 C to prevent the oxidation of Ti at the interface of ZrO 2 /Ti.
