tandgjut14.JPG (14320 bytes)Now it's time to start sculpting the new teeth. For this I use a wax from an art store. On the picture I melt a thin layer of wax onto the plaster teeth so it will be easier to sculpt on it.
Here I am sculpting a pair of crocked, disgusting teeth. To make sure that you won't need any adhesive to make them stay in, I always search for an undercut that will help in snapping the teeth in. Usually it is only needed to cover the first 6-8 teeth and it will stay in great. I think it is totally unnecessary to make a prosthetic that covers all of the teeth as it will be very hard to speak with them.tandgjut15.JPG (15960 bytes)
tandgjut16.JPG (15861 bytes)When I am happy with the sculpture I use my lighter to melt the surface a bit. Why? Because it gets so shiny that you could never do it any other way.
Here is the finished sculpture. I forgot to take a picture of the next step so I will have to explain it in text. On top on the gums I put a piece of clay to make an overflow in the next mold
. This is an important step because when you fill the next mold
with plastic it will be much harder to fit the mold
s together if you don't have an overflow that takes care of the excessive plastic.

Then I hold it in place until it's dry.tandgjut18.JPG (7954 bytes)
tandgjut20.JPG (16783 bytes)A couple of minutes later you can start removing all of the alginate that has gotten on the top of the cast. I use a spatula and sculptors tools to do this. Then carefully lift the teeth up and clean out any leftover wax.
Here it is all separated and is looking good.tandgjut21.JPG (15522 bytes)
