Directions for Use

To ensure proper use of final dentures, dental professionals and patients should follow these steps:

Insertion Protocol:

1. Clean oral tissues with a soft-bristle brush or rinse
2. Hold the denture by the edges; insert using a gentle rocking motion
   1. If it is a partial denture, gently place it in the mouth and use your fingers to guide it into position.
      Avoid using excessive force or pushing the partial denture too far.
3. Instruct the patient to bite and swallow to seat 
   1. If it is a partial denture, instruct the patient to gently bite down on the partial denture to ensure proper fit and stability.
4. Use adhesive if retention is insufficient
5. Use carbon articulation paper to adjust any heavy occlusion points.

Adjustment Guidelines:

• Use high-speed rotary instruments with light pressure
• Maintain temperature with water and air spray
• Avoid dry adjustments to prevent micro-fractures
• Recommended burs:
  • #13 Green Mounted Stone for chair-side adjustments.
  • Rubber wheel for smoothing over the polishable surface after adjustment 

Cleaning and Care **

DAILY CLEANING

Dandy recommends cleaning your dentures daily before and after every use.  Immediately after removal, use warm water (not to exceed 45°C/113°F) and dishwashing soap to remove remaining saliva and debris from the device.

• Only use soft, antibacterial dish soap (liquid)
• Do not use flavored or scented soaps
• Do not use soaps with heavy dyes and colors

USING CLEANING AGENTS

For periodic debris removal and maintenance, use a soft-bristle brush to clean the inside of your appliance. The denture should be cleaned with antibacterial denture cleaning solutions like Polident and Efferdent. These cleaners are designed for use in brief sessions of 10–15 minutes. Always make sure to follow the manufacturer's instructions for proper use.

Do not use:

Avoid immersing the denture in, or cleaning it with, any of the following substances: sodium hypochlorite (chlorine bleach), hydrogen peroxide, mouthwash, or alcohol products. Using these can lead to discoloration and damage to the material.
