How to Adjust a Partial Denture

In this article we have outlined some best practices for adjusting partial dentures based on their material type. 

Metal / Acrylic / Flexible 

• CLASPS:
  • Use pliers to adjust the clasp at the terminal third (last 1⁄3 of the clasp).
  • Bend the clasp outwards for more relief.
  • Gently bend the clasp inward for retention and outward for relief.
• PALATE / INTAGLIO AND FLANGE: 
  • Use bur at high speed with low  pressure to: 
    • Provide relief on guide planes and intaglio 
    • Trim down flange

Flexible

• Soak the partial in hot water for 2-3 minutes.
• Once the partial is heated, it will become more flexible. Hold the clasps in the ideal position for   1-2 mins as it cools.
• Use bur with low pressure to adjust the remaining tight areas.

Denture Teeth

A bur is best used for occlusal adjustment. A rubber wheel is best used for facial adjustment/polishing

• If teeth are too long:
  • Using bite paper, adjust the pontic teeth that are hitting high
  • Use bur at high speed with low pressure to shave down teeth to the proper length
