Mechanical Properties of Polymer-Infiltrated-Feldspar for Restorative Composite CAD/CAM Blocks

Abstract:

Polymer-infiltrated-feldspar used for restorative composite CAD/CAM blocks were prepared by infiltrating polymerizable monomers into the partially sintered feldspar blocks. The flexural strength was tested according to the standard of ISO-4049. The micro-structure was examined by SEM. The effects of sintering temperature, high pressure and the addition of SiO₂ and Al₂O₃ on the ultimate flexural strength were evaluated. The flexural strength corresponding to infiltration with pressure was much higher than that without pressure at high sintering temperature. The addition of SiO₂ and Al₂O₃ into the natural feldspar mineral increased the flexural strength of the blocks significantly.
