Effect of particle deposition protocols on flexural strength of zirconia after cyclic loading

Nov 30, 2017 by in Dental Materials Comments Off on Effect of particle deposition protocols on flexural strength of zirconia after cyclic loading

Objectives: Although air-particle abrasion delivers advantages for improved adhesive strength of resin cements to yttria-stabilized tetragonal-zirconia-polycrystalline (zirconia), it is not widely studied whether this process impairs the mechanical properties of…
