Partial Denture Adjustment Guide

Partials Adjustment Guide 

Metal / Acrylic Flexible 

CLASPS: 

1. Use pliers to adjust the clasp at the terminal third (last 1⁄3 of the clasp).
2. Bend clasp outwards for more relief.
3. Gently bend the clasp inward for retention and outward for relief. 

PALATE / INTAGLIO AND FLANGE: 

1. Use bur at high speed with low  pressure to: 

• • Provide relief on guide planes and intaglio 
  • Trim down flange

Flexible

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

If teeth are too long, causing tight occlusal contact:

1. Using bite paper, adjust the pontic teeth that are hitting high
2. Use bur at high speed with low pressure to shave down teeth to proper length  

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