How and when does fabrication damage adversely affect the clinical performance of ceramic restorations?

Nov 28, 2017 by in Dental Materials Comments Off on How and when does fabrication damage adversely affect the clinical performance of ceramic restorations?

Abstract Objectives As compared to factory-processed ceramic parts, one unique trait of all-ceramic dental restorations is that they are custom-fabricated, which implies a greater susceptibility to fabrication defects. A variety…
