Fixed Restoration IFU

Dandy’s fixed restorations are fabricated using digital technology, allowing for a precise fit and customization to the patient's specific needs. They are made of a highly durable and biocompatible material, ensuring long-term comfort and function.  

Indications for Use

Dandy’s fixed restorations are made to restore worn, carious, broken, and aesthetically unpleasing dentition.

Contraindication

Fixed restorations should be used with caution in patients with uncontrolled periodontal disease, severe bone resorption, or oral lesions.

Potential Risks and Benefits of Fixed Restorations

Advise patients of the following

The use of fixed restorations may have potential risks, including failure, misfit, breakage, and recurrent caries.

However, the benefits include improved speech, comfort, appearance, chewing, and digestion.

Restoration and Cementation

• Test fit all restorations to ensure adequate fit and aesthetics
• Take x-ray if margins are not visible to ensure proper adaptation
• Adjust high spots (using articulating paper to mark areas)
• Cementation of restoration
  • Zirconia Restorations
    • Bond zirconia crowns using a chemical and mechanical pretreatment protocol, such as air-particle abrasion and tribochemical silica coating.
      • The practice will need to sandblast and steam-sanitize all zirconia restorations.
    • Utilize zirconia-specific primers, especially those with 10-MDP, for chemical bonding.
    • Please see: Zirconia Cementation and Adjustment Guidelines, for more information.

• Emax Restorations
  • Versatile cementation choices are available with e.max restorations. Crowns and bridges can be cemented using adhesive, self-adhesive, or conventional methods. Inlays, onlays, and veneers are typically cemented adhesively.
  • Lithium disilicate restorations require etching before placement.
  • For adhesive and self-adhesive cementation of IPS E.Max, silanize restorations are necessary.
  • Please see:  Comprehensive Guide to Cementation of E.Max Restorations, for more information.
• Metal Restorations
  • Metal crowns require air abrasion with alumina particles for enhanced adhesion.
  • Tooth pretreatment
  • Please see: Full Metal and Porcelain Fused to Metal (PFM) Cementation and Adjustment Guidelines, for more information.

Adjustment recommendations

• Operate the bur at high speed, applying minimal pressure while using water.
  • It's important to maintain the temperature using water and air spray. This method helps prevent the formation of micro-fractures. A fine-grit diamond is advisable for adjustments, and air-only handpiece adjustments are not recommended.
  • For shaping different surfaces, specific tools are best:
    •  A football-shaped bur is effective for the occlusal and lingual surfaces, especially on anterior teeth 
    • A tapered bur is better suited for the buccal and lingual surfaces.

Daily Cleaning

• Oral Hygiene:
  • Brushing:
    • Recommended brushing teeth twice a day, using a soft-bristled toothbrush and a fluoride toothpaste.
  • Flossing:
    • Recommend daily flossing to remove plaque and debris from between the teeth and around the fixed restoration. A floss threader may be needed for hard to reach areas  (for bridges).
  • Mouthwash:
    • Alcohol-based mouthwashes, tend to dry out the mouth and lead to increased plaque and tartar buildup.

Dietary and Habit Recommendations

• Avoid abrasive foods: Limit hard, crunchy, or sticky foods that can damage the restoration or cause it to loosen.
• Avoid sugary foods: where new cavities can form or cause premature decay of the restorative margins.
• Stay hydrated: Drinking plenty of water will help keep your patient’s mouth clean and prevent gum disease.
• Avoid bad habits: Refrain from using teeth to open packages or bite on 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

ADA Codes

• Multiple codes are available
• Please consult with a CDT for recent information.
