Instructions for use for complete dentures (IFU)

Overview: This article provides the indications, contraindications, insertion protocols, and maintenance requirements for Dandy Complete Dentures to ensure patient safety and device longevity.

Indications and device offerings

Dandy Complete Dentures are digitally fabricated, removable prostheses intended to replace missing natural teeth and oral structures in fully edentulous patients. These dentures utilize biocompatible materials for precise fit and long-term function.

Contraindications and risks

Do not use complete dentures in patients with uncontrolled periodontal disease, severe ridge resorption, untreated oral lesions, or known hypersensitivity to acrylic, PMMA, or methacrylate monomers.

Potential Risks:

• Gingival irritation or mucosal soreness.
• Instability due to poor adaptation.
• Allergic response to base or teeth materials.

Insertion and adjustment protocols

Follow these steps to ensure the complete denture is seated correctly and adjusted without damaging the material.

Insertion Steps:

1. Clean the patient's oral tissues with a soft-bristle brush.
2. Hold the complete denture by the edges and insert it using a gentle rocking motion.
3. Instruct the patient to bite and swallow to fully seat the device.
4. Apply adhesive if retention is insufficient.

Adjustment Guidelines:

• Use high-speed rotary instruments with light pressure.
• Use water and air spray to maintain temperature; avoid dry adjustments to prevent micro-fractures.
• HIPA Materials: Use cooling during adjustment to preserve resin integrity.
• 199 Resin Materials: Adjust gently to avoid delamination.
• PMMA Materials: Use carbide burs and polish for the final finish.

Daily cleaning and maintenance

Dandy recommends cleaning complete dentures daily before and after every use to remove saliva and debris.

Daily Cleaning Steps:

1. Remove the complete denture and rinse with warm water (not exceeding 45°C/113°F).
2. Use a soft, liquid, antibacterial dish soap that is unscented and dye-free.
3. For periodic maintenance, use a soft-bristle brush to clean the inside of the appliance.

Approved Cleaning Agents:

• Polident (10–15 minute sessions).
• Efferdent (10–15 minute sessions).

Prohibited Substances: Do not immerse complete dentures in chlorine bleach, hydrogen peroxide, mouthwash, or alcohol products, as these cause material discoloration.

Additional Information

• Clinical studies have shown final dentures to be an effective and reliable treatment option for patients with missing teeth.
• If the patient experiences any adverse events, such as pain or irritation, they should discontinue use and contact your practice immediately.
• Final dentures have a limited warranty, which may vary depending on the manufacturer.
• Smoking with the dentures inserted can cause discoloration

Storage and disposal

When not in use, store complete dentures in a clean, dry place away from excessive heat.

Disposal Instructions:

• Treat used complete dentures as biohazardous waste due to contact with saliva or blood.
• Use red bags and authorized carriers for disposal.
• Check local regulations before placing items in the general waste.
