Clinical and technical procedures (step-by-step) for the chairside fabrication of multilayer zirconia crowns.

Step	Clinical procedures	Technical procedures
1	Adhesive build-up Preparation Soft tissue management Placement of retraction cord
2	Intraoral scanning Preparation, antagonistic jaw and buccal scan (bite registration)
3		CAD design Preparation analysis (substance reduction, undercuts, artefacts) Determination of preparation limit Modification of the restoration design
4		CAM process Selection of ceramic block Dry-milling Speed-sintering
5		Staining and glazing of the restoration Conditioning of the intaglio restoration surface (air-abrading process)
6	Try-in Verification of correct shade Occlusal and proximal adjustments if needed
7	Luting Definitive cementation (e.g., self-adhesive cement) or provisional cementation
