Wear quantification of human enamel and dental glass–ceramics using white light profilometry

Influence of Full‐Contour Zirconia Surface Roughness on Wear of Glass‐Ceramics

“…The flat surface of the specimen was affixed with a thin layer of blue wax (Inlay Wax Hard Blue; Henry Schein, Inc, Melville, NY) to the surveyor rod on its flat end, and then the rod was gradually lowered until the specimen base was embedded in the resin of the brass holder. The surveyor rod was maintained in position until the resin polymerized to ensure the specimen surface remained 1.5 mm above the resin …”

“…EX specimens were sintered in a furnace (Ney CeramPress Q50; Dentsply International, York, PA) according to the manufacturer's instructions for final crystallization. Finally, all specimens were mounted in brass holders with the testing surface perpendicular to the long axis of the brass ring using a customized silicone mold and autopolymerizing acrylic resin . Specimens were wet‐finished with 1200‐ and 2400‐grit silicon carbide paper to ensure the flat and smooth surface.…”

“…The difference between the base height and the zirconia slider tip was measured . For glass‐ceramic tabs, surface wear was calculated by measuring height and volume loss using non‐contact optical profilometry (Proscan 2000) . The S38/3 sensor was used for scanning at a 50 μm step size in both x and y directions.…”

Dimensional Measurement for Dentistry

“…With surface form (shape) measurements, Co-ordinate Measuring Machines (CMMs) are more suited for the inspection of automotive parts in industry since the 1950's (Bosch, 1995). Since the late 90's, along with the development of new technology in optics and computing, numerous applications have been advanced in the fields of medicine and dentistry (Chadwick, 1989;Seymour et al 1996;Kabban, et al 2001;Zou, et al , 2009Cherukara GP et al 2002;Theocharopoulos et al, 2010;Morris et al 2011 ).…”

Solid-state reaction in nanoparticulate alumina/LZSA glass-ceramic composites

“…For decades, synthetic glass-ceramics have been studied to understand their thermal behavior and also the relationship between composition, processing and microstructure. In the last decades, different applications for glass-ceramics have been studied based on their mechanical [2][3][4][5], thermal [6][7][8], electrical [9][10][11][12], biological [3,[13][14][15][16], and optical [17- 19] properties, among others. Glass-ceramics are produced from a controlled crystallization of a glass that generates a microstructure formed by one or more crystalline phases, eventually some porosity, and a residual glassy phase, since crystallinity ranges from 0.5 to 99.5%, although it achieves typical values between 30 and 70% [20].…”
