Onyx / Clinical Protocols

Clinical Protocols

Esthetic dentistry should be quantifiable. These protocols give your team and the Onyx team the same records, the same measurements and the same steps, from the first photograph to cementation.

01The Onyx Workflow

Five steps, two approvals.

Every Onyx case moves through the Hybridge portal in the same order. The protocols below support each step.

01
Upload initial records
- Initial intraoral scans
- Photos following the Onyx Photographic Protocol for DSD
02
Approve the diagnostic design
- Review in the Exocad Viewlink app
- Receive the wax-up STL file or a 3D printed model
- Review the Tooth Preparation Protocol for your material
03
Prepare and upload final records
- Tooth preparation and provisional scans, analyzed with the Onyx team
- Photos following the Shade Selection Protocol
- Confirm the delivery date
04
Approve the definitive design
- Review in the Exocad Viewlink app, then approve or suggest modifications to the Onyx team
05
Try-in and deliver
- Follow the Adhesive Cementation Protocol
- Upload a scan for a night guard when applicable

02Photographic Protocol

Six views for Digital Smile Design.

Upload these views with your initial records. They become the foundation of the 3D diagnostic design.

04Tooth Preparation Protocols

Prepare for the material.

Ceramic materials for definitive restorations

Silicate ceramics

Feldspathic and lithium silicate (e.max)

Oxide ceramic

Zirconia (zirconium oxide)

Feldspathic

Indications

Veneers
Anterior crowns on non-discolored abutment teeth

Feldspathic veneer preparation diagram: 0.5 to 0.7 mm incisal, 0.5 mm labial, 0.2 to 0.3 mm cervical

Veneers

Ceramic layer thickness

Incisal0.5 to 0.7 mm

Labial0.5 mm

Cervical0.2 to 0.3 mm

Feldspathic anterior crown preparation diagram: at least 1.5 mm incisal and 1.0 mm circumferential

Anterior crowns

Ceramic layer thickness

IncisalAt least 1.5 mm

CircumferentialAt least 1.0 mm

Crown margin1.0 mm

Lithium Silicate (e.max)

Indications

Veneers
Anterior and posterior crowns
Inlays, onlays, vonlays

Shoulder or chamfer preparation.

Lithium silicate preparation diagrams: shoulder and chamfer preparation, with minimum reduction for a veneer, an anterior crown and a posterior crown

Final 3D Design Approval

For both provisional and final restoration designs, a brief virtual session with the Onyx team is recommended.

05Adhesive Cementation Protocol

Six steps to delivery.

Recommended bonding protocols for ceramic restorations, by material. Every restoration leaves the lab with its surface already treated, so chairside work starts at try-in.

Feldspathic and lithium silicate (e.max)

At the lab. Feldspathic ceramic and e.max restorations are already acid etched.

Silane

Resin cement

Bonding protocol for both materials

1Intraoral restoration try-in
2Ultrasonic cleaning in alcohol for 5 min, or with a specific cleaner
3Silane application for 20 s and dry
4Proper isolation
5Pretreat tooth surfaces, per manufacturer’s recommendations
6Light-cure or dual-cure composite resin cement

Zirconia

At the lab. Zirconia restorations are already air-particle abraded.

Bonding protocol

1Intraoral restoration try-in
2Ultrasonic cleaning in alcohol for 5 min, or with a specific cleaner
3Application of special phosphate monomer-based primer
4Proper isolation method
5Pretreat tooth surfaces
6Dual-cure or self-cure composite resin luting agent
