Evaluation of the flexural strength of metal frameworks fabricated by sintering-based computer-aided manufacturing methods
Sintering-based computer-aided metal manufacturing strategies have been proposed as an alternative to hard metal milling. While these fabrication methods have been evaluated in terms of marginal and internal discrepancies and bond strength to porcelain, limited information on metal frameworks is available regarding their flexural yield strength.Digital evaluation of laser scanning speed effects on the intaglio surface adaptation of laser-sintered metal frameworks
Laser sintering has several processing parameters, typically under the control of dental laboratory technicians. Laser scan speed is an important parameter, which has a significant effect on manufacturing time but may also affect the adaptation of restorations. However, limited information is available regarding its impact.The effect of layer thickness on the porcelain bond strength of laser-sintered metal frameworks
Laser sintering has become a common manufacturing technique in the fabrication of metal-ceramic restorations. The layer thickness of the sintering process may affect the surface morphology and hence the porcelain bond strength. However, limited information is available on the effect of layer thickness on porcelain bond strength.
