+Detailed description

Digital dentistry has progressed rapidly in the last few years, primarily to improve and enhance the practice of dentistry through the advancement in digital tools and techniques, providing improved accuracy and precision, enhancing patient experience, increasing efficiency and productivity, thereby resulting in better treatment outcomes, whilst also improving clinical outcomes.

+Arms and interventions

Arm	Type	Interventions	Description
milled zirconia crowns	Experimental	Procedure: Each group was received monolithic ceramic crowns fabricated using different technique	this group was received milled zirconia crowns on their posterior molars indicated for full coverage restorations.
milled hybrid ceramic crowns	Experimental	Procedure: Each group was received monolithic ceramic crowns fabricated using different technique	this group was received milled hybrid ceramic crowns on their posterior molars indicated for full coverage restorations.
3d printed hybrid ceramic crowns	Experimental	Procedure: Each group was received monolithic ceramic crowns fabricated using different technique	this group was received 3d printed hybrid ceramic crowns on their posterior molars indicated for full coverage restorations.

Each group was received monolithic ceramic crowns fabricated using different technique (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.

+Outcome measures

Primary outcomes

the clinical performance, color stability and wear behavior of monolithic ceramic crowns fabricated using innovative digital techniques. [baseline, 3months and 6 months after crown cementation]: 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. * Color stability will be evaluated using a spectrophotometer. * Wear of restorations will be evaluated using a software analysis.

+Eligibility
