Clinical Behavior and Patient Satisfaction of Zirconia-reinforced Glass-ceramic Crowns and Ultra-translucent-multilayered Monolithic Zirconia Crowns With a Conservative Marginal Design
Starting soon · Not applicable
Conditions studied: Clinical Behavior of ZLS and UTML
In brief
The aim of the present study is to evaluate clinical behavior and patient satisfaction of Zirconia-reinforced lithium disilicate press ceramic crowns when used in a conservative marginal design(0.6mm chamfer finish line). Comparison with Ultratranslucent multilayered monolithic zirconiacrowns will also be carried out in terms of marginal integrity, fracture, color stability and gingival health for 12 month
