Marginal and internal fit of contemporary monolithic zirconia inlays: Impact of resin cement, and thermomechanical aging

This study found no significant difference in marginal fit between Zolid Gen-X (4Y-TZP) and IPS e.max ZirCAD Prime (3Y-TZP/5Y-TZP gradient) under tested conditions. Both materials achieved clinically acceptable fit. However, RelyX cement provided significantly better marginal integrity than Panavia, and aging significantly increased marginal gaps. Internal fit was unaffected by material, cement, or aging, but exceeded ideal values. Cement choice and aging are crucial factors for marginal seal longevity.

Abstract

This study found no significant difference in marginal fit between Zolid Gen-X (4Y-TZP) and IPS e.max ZirCAD Prime (3Y-TZP/5Y-TZP gradient) under tested conditions. Both materials achieved clinically acceptable fit. However, RelyX cement provided significantly better marginal integrity than Panavia, and aging significantly increased marginal gaps. Internal fit was unaffected by material, cement, or aging, but exceeded ideal values. Cement choice and aging are crucial factors for marginal seal longevity.
