Overview: This article provides comprehensive instructions for use (IFU), indications, and maintenance guidelines for Dandy ceramic veneer restorations to ensure optimal patient outcomes.
Understanding Veneer Restorations
Dandy restorations are fabricated using digital technology to enable a precise fit and customization for specific patient needs. These veneers consist of highly durable, biocompatible ceramic material designed for long-term comfort and function.
Indications for Use
Clinicians should use Dandy veneer restorations to restore dentition that is:
Worn, carious, or fractured.
Discolored or misaligned.
Aesthetically unpleasing.
Veneers restore the form, function, and aesthetics of natural permanent teeth while maintaining proper interarch relationships and occlusal stability.
Contraindications and Risks
Veneers should be used with caution in patients with:
Uncontrolled periodontal disease.
Severe bone resorption.
Active oral lesions.
Warning – Sensitivity: This device contains trace levels of cobalt and chromium oxides. Clinicians must inform patients with known sensitivities to these metals before treatment, as rare allergic reactions can occur.
Warning – Irritation: Localized irritation of oral tissues may occur. Clinicians should monitor patients post-placement for signs of inflammation or discomfort.
Restoration and Cementation
Before final placement, clinicians must test the fit of all restorations to ensure adequate aesthetics and evaluate all margins for proper adaptation. Use articulating paper to identify and adjust high spots.
Zirconia Cementation Guidelines
For zirconia restorations, follow these specific protocols:
Pretreatment: Use a chemical and mechanical pretreatment protocol, including air-particle abrasion and tribochemical silica coating.
Sanitization: Sandblast and steam-sanitize all zirconia restorations before bonding.
Priming: Utilize zirconia-specific primers (specifically those with 10-MDP) for chemical bonding.
Emax Cementation Guidelines
Emax restorations (lithium disilicate) require specific preparation:
Etching: Lithium disilicate restorations must be etched before placement.
Silanization: Silanize restorations for adhesive and self-adhesive cementation.
Method: While crowns can use various methods, veneers are typically cemented adhesively.
Adjustment Recommendations
When adjusting ceramic veneers, follow these technical standards to prevent micro-fractures:
Speed and Pressure: Operate the bur at high speed with minimal pressure.
Cooling: Maintain temperature using constant water and air spray.
Tool Selection: Use a fine-grit diamond bur; do not use air-only handpiece adjustments.
Surface Shaping: Use a football-shaped bur for lingual and occlusal surfaces and a tapered bur for buccal and lingual surfaces.
Patient Maintenance and Cleaning
Advise patients to maintain oral hygiene to protect the restorative margins and prevent premature decay.
Daily Hygiene Practices
Brushing: Brush twice daily using fluoride toothpaste and a soft-bristled toothbrush.
Flossing: Floss daily to remove plaque from around the restoration; use a floss threader for hard-to-reach areas.
Mouthwash: Avoid alcohol-based mouthwashes as they can increase plaque and tartar buildup by drying the mouth.
Dietary and Habit Recommendations
Avoid Hard Foods: Limit crunchy or sticky foods that could loosen or damage the veneer.
Sugar Limitation: Limit sugary foods to prevent new cavities.
Avoid Misuse: Do not use teeth to open packages or bite hard objects.
Smoking Cessation: Smoking can cause discoloration at the restoration margins.
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 at the margins
Disposal Procedures
Ceramic restorations do not break down in standard recycling and require specific disposal methods.
Biomedical Waste: If the restoration has been in the patient's mouth or contacted saliva, it must be discarded as biomedical waste.
Solid Waste: New/unused all-ceramic restorations can be disposed of in regular household trash.
Recycling: Take ceramic items to specialized centers that accept construction debris or mixed ceramics.
