Fit of cast commercially pure titanium and Ti-6Al-4V alloy crowns before and after marginal refinement by electrical discharge machining

Comparison of an analog and digital quantitative and qualitative analysis for the fit of dental copings

“…Both measurement techniques used in this study showed comparable results and are in the range of the values of former studies which used well-established methods like the cross-sectioning technique [20], direct view technique [30] and also replica technique [22]. However, the ODKM 97 generally tended to show higher values than the LMM especially for the marginal and incisal measurements, which partially can be explained by the powder that had to be applied against surface reflection and light scattering.…”

Applications of Current Technologies for Nondestructive Testing of Dental Biomaterials

“…In addition, they regularly evaluate the passivity of the fit of their cast prosthesis superstructure utilizing a stereomicroscope. If they detect any misfit between the cast superstructure and the supporting teeth and/or implants, they will correct the problem using recasting, soldering, welding and electrodischarging machining techniques (Contreras et al 2002;Ntasi et al 2010;Romero et al 2000;Zinelis 2007). …”

Tensile and Flexural Strength of Commercially Pure Titanium Submitted to Laser and Tungsten Inert Gas Welds

“…Titanium and its alloys are used since 1950, first in the aerospace industry and currently in several areas including Dentistry, due to its excellent biocompatibility, low density, high module of elasticity, high resistance to corrosion, low cost and low thermal conductibility (2)(3)(4). These characteristics allow their use by lost wax technique and mechanical and electronic polishing process is facilitated, increasing its applicability.…”
