The Influence of Three Different Digital Cement Spacers on the Marginal Gap Adaptation of Zirconia-Reinforced Lithium Silicate Crowns Fabricated by CAD-CAM System

Applied Sciences, 2021
Background: This study compared the influence of three different radial spacers (60,90,120 microns) on the marginal gap adaptation by using computer-aided manufacturing (CAD-CAM) for producing monolithic zirconia reinforced lithium silicate (ZLS) ceramic

Effect of Different Types of Construction Techniques on the Vertical Fit of Screw-Retained Fixed Implant-Supported Prosthesis [PDF]

Journal of Mashhad Dental School, 2021
Introduction: Marginal misfit in screw-retained implant restorations when screwing torque leads to deformation of superstructure and formation of strain in the lower bone.

Crystallization firing effect on the marginal discrepancy of the IPS. emax CAD crowns using two different CAD/CAM systems

Journal of Baghdad College of Dentistry, 2023
Background: Marginal adaptation is critical for long – term success of crown and bridge restoration. Computer aided design / computer aided manufacture (CAD/ CAM) system is gaining more importance in the fabrication of dental restoration. Objective: The

A New Keynesian Triangle Phillips Curve [PDF]

, 2013
We propose a solution to address the observed negative sign on the marginal cost variable in new Keynesian Phillips curve estimations. Our solution is based on an elaborate specification of the cost function faced by firms and the formulation of a ...

Convergence properties of pseudo-marginal markov chain monte carlo algorithms [PDF]

, 2015
We study convergence properties of pseudo-marginal Markov chain Monte Carlo algorithms (Andrieu and Roberts [Ann. Statist. 37 (2009) 697-725]). We find that the asymptotic variance of the pseudo-marginal algorithm is always at least as large as that of ...
