Fill dental try with alginate.
Wait several minutes and remove the tray. If it sticks wiggle it a little to break up the vacuum it may have made.
Mix Ultracel and pour into the cast you made. Tap the cast to release air bubbles and to allow the Ultracel to fill all areas. Let the cast with Ultracel rest for 45 minutes to an hour.
Separate case from tray very carefully as to not damage the plaster.
Use your various dental tools and dremel to fix the plaster casting using great care to not break it.
Set your plaster mould upright on the table with the teeth facing upward.
Melt a thin layer of wax onto the plaster.
Using your sculpting tools sculpt the teeth how you would like them.
Use your lighter and melt the surface of the teeth ever so slightly to create a smooth and shiny surface.
Place some clay over and above the gum line (used to create an overflow for the next mold).
Mix up alginate and fill a container large enough to fit the cast inside of it.
Submerge the entire cast in to the alginate.
Hold in place until dry.
Remove excess alginate that has got on top of your cast with your tools when the alginate has dried.
Carefully remove cast from alginate.
Remove any leftover wax that is still in the alginate mould.
Paint a thin layer of the release agent on to the cast. Let dry and repeat two more times.
Drip a little acrylic fluid into the mould and slush it around.
Gently sprinkle acrylic powder in to the teeth mould. Vary the colours from transparent to light tooth shade to yellow and then to dark to create a realistic shade.
Reposition the plaster teeth into the mould making sure it fits snugly.
Place a very light weight on top of the plaster case that is inside the mould. Wait several minutes.
Place the mould inside of the pressure cooker that is filled with hot water.
Wait ten to fifteen minutes. If you do not have a pressure cooker wait for thirty to forty-five minutes.
Remove it from the pressure cooker.
Separate the moulds very carefully.
Remove the plastic teeth from the cast.
Remove excess spill plastic by using your dremel tool.
Polish the teeth with a soft bristle toothbrush and toothpaste.
Tips and warnings
- If you want normal dentures skip Section 2 and 3.
- Broken plaster means having to start over.
- Never rush.
- When fitting in the dental tray with alginate do so standing up and bent of a sink.
- If you do not intend to fill your cast with plaster right away submerge it in hot water so it will not shrink.
- You can sometimes make a second denture from the plaster mould but usually you will need to remake the plaster cast.
- You can create gums by using the same "dripping" technique as with the teeth.
- You can paint on colour by using slightly watered down grease paint. It will soak into the plastic and not smear.
- If the teeth do not fit snugly trim as needed with the dremel tool.
- Working with these chemicals are dangerous and should only be worked on in a forced ventilation system area.
- Always wear safety glasses and mask.
- When fixing up your first cast do not remove the muscle between the teeth and gum.
