Multilayer Super-Translucent Zirconia for Chairside Fabrication of a Monolithic Posterior Crown

Table 1

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
