Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
milled zirconia crowns
this group was received milled zirconia crowns on their posterior molars indicated for full coverage restorations.
Each group was received monolithic ceramic crowns fabricated using different technique
-Different digital techniques used for fabrication of the monolithic ceramic crowns were chosen for the current study, Clinical performance of all crowns regarding; marginal adaptation, fracture of restoration during service, color stability and wear behavior will be evaluated according to Modified United States Public Health Service (USPHS) Criteria at base line (1 week), 3 and 6 months after cementation of crowns.
