Card Set Information
What are 2 methods for denture processing?
What are the reqs for denture resin?
stiffness, low creep
: occlusion, minimize uneven loading
: mastication, impact
resist oral environment
What are different types of denture base materials?
heat cured, rubber reinforced
heat cured, fiber reinforced
: low solubility, water uptake, dimensionally stable, accurate
Which denture base has least shrinkage?
light cured (3% vs 6% cold, heat cured)
What is the heat cure rxn?
polymer & peroxide initiator (powder) +
monomer & inhibitor (liquid) +
->> polymer + heat (reaction)
Adv of injection molding?
less distortion during processing
minimal pin opening
-->> lab remount simplified
What is flasking injection channel requirements?
3-5mm diameter 1 for max, 2 for mand
Flasking process steps
1. complet festooning
2. seal to cast
3. remove from mounts
4. place in flasks partially filled with stone
5. coat teeth with improved stone
6. fill and close
7. boil out
: wax and record base
8. alcote stone but not teeth
9. mix polymer 20g polymer, 30ml monomer for 5 minutes room temp
10. assemble and clamp flask
11. mount pressure apparatus
Lab remount purpose
1. correct processing errors
2. restore VDO
3. restore centric and bilateral balanced occlusion
