Procedure to make Flexible dentures

1. Welcome!

2. Update Acrylics Acrylic heat curing Pressing technique Polymerizes by boiling at 100 ° C Full dentures Partial dentures Metal frame

3. Update Acrylics Acrylic self curing For repair, relines and addition Polymerizes by 55 ° C For best result need to use a pressure pot

4. Update Acrylics History: Heat-curing acrylics since 1936 Cold-curing acrylics since 1958 Colour stable Cold-curing acrylics since 1982 Colour stable Cold-curing acrylics for full dentures since 1992

5. Update Acrylics Colour stable self-curing acrylics for all denture work ?? And you can use the pouring technique? Did I miss something?

6. Update Acrylics Introducing Vertex-Dental Castapress Cold Curing Pouring technique Injecting with syringe

7. Vertex Dental Castapress Advantages: No discoloration (not like standard self curing!!) Strong (not brittle) Fast! No investing & No pressing No damage of frame after de-vesting Less waste of material

8. Vertex Dental Castapress Marginal gap in micrometer measured by a non-contact laser scanner. The 5 most important test points along the posterior border line of an upper denture. 1 3 5 2 4 Material: 1 2 3 4 5 Castapress 180 70 230 30 110 Ivocap “plus” 160 170 280 60 150 Paladon 65 350 115 550 120 700 Futura Jet 700 60 240 40 700 Le Cast 240 60 550 60 350

11. YUWEI Dental MEISUI TIDAK ADA investing? TIDAK ADA gips/plaster? TIDAK ADA PEMANASAN AIR? TIDAK ADA pendinginan ? NO! HEMAT WAKTU 70%!

12. YUWEI Dental MEISUI Stone model Wax-up seperti biasa Campur putty Aplikasi kan putty

13. Vertex Dental Meisui Keluarkan gigi nya De-wax the stone, denture frame and teeth Soak the model in water for about 5 minutes Apply separator

14. Vertex Dental Castapress Create extra retention on the teeth Create Injection/ pouring channel Place back the teeth, apply super glue if needed to fix the teeth position Apply Acrybond or monomer for better bonding

15. Vertex Dental Castapress Carefully place back the impression Inject the acrylic with a syringe Or pour the acrylic Polymerize in pressure pot

16. Vertex Dental Castapress Remove silicone rubber Grind the acrylic Polish to high shine

17. Vertex Dental Castapress Benefits: Work up to 70% faster More efficient No extra costs High quality Dentures Less waste of material

26. Q: Teeth come off denture A: - Surface not grinded ( too smooth) - Wax residue on teeth ( oil from wax) - Did not apply monomer or Acrybond Q: Marble effect A: -Poor initial mixing -Contaminated mix from to much separating solution Trouble shooting

27. Q: Translucent gingiva or periphery A: Packing to early ( too liquid) Q: Holes (bubbles) or voids A: - Incorrect spruing (too small) - Packing to early (injection too fast) - Model not soaked in water (air comes out of model) Q: Moving teeth A: Turbulent injection ( spruing to high) Trouble shooting
