Adhesion of dental porcelain to cast, milled, and laser-sintered cobalt-chromium alloys: Shear bond strength and sensitivity to thermocycling

Effects of multiple firings on metal-ceramic bond strength of Co-Cr alloy fabricated by selective laser melting

“…[4][5][6][7] Additionally, the corrosion resistance of SLM specimens is similar to that of conventional processing. 16,21 The process of fabricating metal ceramic crowns requires a series of porcelain firings to achieve esthetic and clinical requirements. Thus, repeated firings of restorations are inevitable.…”

Effect of various intermediate ceramic layers on the interfacial stability of zirconia core and veneering ceramics

“…Many studies have attempted to evaluate the interfacial bonding quality between the Y-TZP substrate and veneering material through a common in vitro shear bond strength test [26,28,34,35]. However, critical assessments of the conventional in vitro research methods have shown that conventional shear protocols fail to consider uniform distribution of shear stresses [36].…”

Comparison of the metal-ceramic bond after recasting and after laser sintering

“…4 Co-Cr dental alloy fabricated with selective laser melting is a promising alternative to conventional cast alloy for metal ceramic restorations. 5 Liu et al 15 showed no effect on porcelain compatibility when 3 noble alloys were remelted twice, even without the addition of new alloy; these results are similar to the present results.…”

“…Laser sintering is a new technology that can substitute for base metal alloy casting [3][4][5] and has recently been considered a computer-aided design/computer-aided manufacturing method. The metal frameworks of partial fixed dental prostheses, facial prostheses, surgical models and stents, and titanium implants can be fabricated with these systems.…”
