Overview: This article provides comprehensive Instructions for Use (IFU) for Dandy ceramic crowns, including indications, contraindications, cementation protocols, and patient maintenance..
Indications and Clinical Use
Dandy ceramic crowns use digital technology to restore form, function, and aesthetics. Clinicians use these crowns to:
Restore single, permanent teeth that are fractured, discolored, or severely worn.
Replace missing permanent teeth by spanning edentulous spaces with dental implants.
Provide occlusal stability.
Contraindications and Safety Warnings
General Contraindications
Use caution in patients with uncontrolled periodontal disease, oral lesions, or severe bone resorption.
Metal Sensitivity Warning
Ceramic material contains trace levels of cobalt and chromium oxides. Clinicians must inform patients with known metal allergies or sensitivities prior to treatment.
Tissue Irritation Warning
Individual variability may cause localized irritation. Clinicians should monitor patients post-placement for signs of inflammation or discomfort.
Restoration and Cementation Protocols
General Fit Testing
Test fit all restorations to ensure adequate aesthetics. If margins are not clearly visible, take an x-ray to ensure proper adaptation. Use articulating paper to identify and adjust high spots.
Zirconia Cementation
Pretreatment: Use a chemical and mechanical protocol, including air-particle abrasion and tribochemical silica coating.
Sanitization: Sandblast and steam-sanitize all Zirconia restorations before placement.
Priming: Utilize Zirconia-specific primers containing 10-MDP for chemical bonding.
E.max (Lithium Disilicate) Cementation
Etching: Etch all lithium disilicate restorations before placement.
Silanization: Silanize restorations for adhesive and self-adhesive cementation.
Method: Use adhesive methods for inlays, onlays, and veneers; crowns and bridges support adhesive or conventional methods.
Adjustment Recommendations
To prevent micro-fractures, clinicians should:
Use a fine-grit diamond bur at high speed with water and air spray to maintain temperature.
Avoid air-only handpiece adjustments.
Use a football-shaped bur for occlusal and lingual surfaces.
Use a tapered bur for buccal and lingual surfaces.
Patient Maintenance and Care
Daily Hygiene
Brushing: Brush twice daily using fluoride toothpaste and a soft-bristled brush.
Flossing: Floss daily. For bridges, clinicians should recommend a floss threader.
Mouthwash: Avoid alcohol-based mouthwashes as they may increase plaque buildup.
Dietary Habits
Avoid hard, crunchy, or sticky foods that may loosen the restoration.
Limit sugary foods to prevent decay at restorative margins.
Do not use teeth to open packages or bite hard objects.
Additional Information
- If the patient experiences any adverse events, such as pain or irritation, they should contact your practice immediately.
- Fixed restorations have a limited warranty, which may vary depending on the manufacturer.
- Smoking with restorations can cause discoloration
Disposal Instructions
Standard Disposal
Dispose of all-ceramic restorations as regular solid waste if they have not contacted saliva. Place them in a regular garbage bin or take them to a center accepting mixed ceramics.
Biomedical Waste
Restorations that have been in the patient's mouth or contacted saliva must be discarded as biomedical waste.
