Monolithic Ceramic Crowns Fabricated by Different Digital Techniques

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

study is performed on 3 groups

\- Different digital techniques used for fabrication of the monolithic ceramic crowns were chosen for the current study; milled zirconia for the group (I) and milled hybrid for the group (II) and 3D-printed hybrid for the group (III).

NONE

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.

Group Type EXPERIMENTAL

Each group was received monolithic ceramic crowns fabricated using different technique

Intervention Type PROCEDURE

-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.

milled hybrid ceramic crowns

this group was received milled hybrid ceramic crowns on their posterior molars indicated for full coverage restorations.

Group Type EXPERIMENTAL
