About

There is limited data available on VITA AMBRIA glass ceramic , so this study is conducted to investigate the esthetic parameters of this new glass press system.

Full description

This study will be randomized, double blinded, 1:1 parallel group, superiority clinical trial. including two research groups; VITA AMBRIA ( intervention) and IPS e.max press( Comprator). The total subjects in this study are 50, recruited from the faculty' out patient clinic. 50 partial coverage indirect restorations will fabricated and cemented for each subject. Clinical evaluations will be conducted at baseline, 6, and 12 months of follow-up according to FDI World Dental Federation criteria by two independent evaluators. The primary outcome is examining the color stability and translucency.
