Everything you’ll learn you need can be bought at a dental supplier. Start by testing a tray for size.
Step 1: Make a Cast
Filling the tray with a thick mixture of alignate.
Let the patient put the tray in by themselfs and ask them to lean forward and drool.
A few minutes later the alignate is dry and it is time to remove the cast. Sometimes it may stick a bit but that is only a vacuum and if you wiggle it a bit it will come loose. If you don't intend to fill it with plaster at once submerge it into water so it won't shrink.
Now mix a little Ultracal carefully, pouring it down the mold. Then tap the mold against the table so the last airbubbles will come to the surface. Let it set for about 45 minutes before you separate the molds.
Then fix the edges but be very careful not to damage the cast. You now have a finished cast of the clients teeth. Note the little muscle that normaly is under the lip.
It's important that you don't remove it as you can damage the muscle if you make a pair of teeth without making a slit for it.
Step 2: Sculpt the teeth
Use a wax from an art store. Melt a thin layer of wax onto the plaster teeth so it will be easier to sculpt on it. To make sure that you won't need any adhesive to make them stay in, search for an undercut that will help in snappning 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.
When happy with the sculpture, use a lighter to melt the surface a bit so it gets so shiny that you could never do it any other way.
Step 3: Another mold
On top on the gums 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 molds together if you don't have an overflow that takes care of the excessive plastic. Fill a small jar with alignate and submerge the whole thing into it.
Then hold it in place until it's dry. A couple of minutes later you can start removing all of the alignate that has gotten on the top of the cast. Use a spatula and sculptors tools to do this. Then carefully lift the teeth up and clean out any leftover wax.
Step 4: Release agent
Put on some special release agent. Let it dry between layers and apply 2-3 layers.
With rubber gloves on start dripping a little acrylic fluid into the mold and slush it around. Always work under forced ventilation and keep gloves on the whole time as this can be hazardous to your health. Gently sprinkle the acrylic powder down in the teeth mold. Start with a little transparent powder and continue with a light
toothshade. Then continue with a little more yellow and last a quite dark one. This is for making the teeth seem like they have a natural shade. Unfortunatly it is very hard to get it right the first time, only experience will help you here. When the correct amount of acrylic mixture is in the mold gently reposition the plaster teeth into the mold. It is very important to make it fit as snugly as is did when you made the mold. Any misplacement will make the teeth to become to think or some other defect. Place the mold under light presure for a couple of minutes. Place the molds into a pressure cooker (3 bar) with hot water for final hardening. Wait for 10 to 15 minutes.
If you don't have a pressure cooker you will ahve to wait maybe 30-45 minutes.
Hopefully you now can separate the molds and take out a good cast.
Sometimes you can make a second casting but often the plaster teeth becomes bad.
Step 4: Take Teeth Off
Now it's time to very carefully take the teeth off. This can be very hard but putting them in warm water will make the release agent to dissolve and help a bit. Now things can get bad The teeth is at this point very fragile and if it breaks it will be hard to fix them. When the gums is finished they will be a lot more stable but not yet. If something that you need had broken you will have to start all over. Using a Dremel tool you cut down all unnessecary spill plastic. A lot of people who do this kind of work make a negative mold for the gums, just like for the teeth but instead you should "drip" the gums. This is done by taking fluid and powder and form a gum right on top of the cast. Continue to do this until it has gotten as thick as you want it. Grind the finished plastic teeth. Polish is a very important step in this quite long procedure. Normally polish with ordinary tooth paste that actually works very well.
Step 5: Finishing touches
Paint a little dark brown between the teeth and make the gums a little more red with ordinary makeup colors. The grease paint sinks into the plastic and won't smear.
Apply a thin layer of nail polish for a nice shine. Now it's time to fit them on the actor. It's important that they don't hurt you anywhere or fits to hard on some places. This can cause damage to the actors teeth or gums and you will get sued for millions of dollars. You will have to grind them down to a perfect fit so they won't fall out or hurt your actor. This can be hard but take a little at a time and work slowly.
Fangs
Needed:
• Friendly Plastic (hobby/craft stores)
• Pan
• Stove
• Tap water
Steps:
1. Put ordinary tap water on a pan, and bring it to a boil. Then pour the water into a coffee-mug and take it to your making area (with mirror).
2. Cut small pieces of friendly plastic (into pieces about the size of a half-dollar) and put them into the hot water using a table spoon.
3. Remove the Friendly plastic from the hot water after it has been in for about 20 seconds (time may vary).
4. Mold the friendly plastic to your tooth that you want to extend, and be sure to have a little bit more than What You Need: to cover your tooth, the excess is used for shaping to the roof of your mouth to be used as a retainer for holding the tooth in place.
5. Once you have the friendly plastic in your mouth, and covering your tooth, mold it to the desired shape and length.
6. After achieving the desired shape and length, leave the friendly plastic on your tooth for a minute or two, this allows it to harden in your mouth helping it retain the actual shape that holds it in place. You can also drink cold water to speed the
hardening process, but, be careful not to shift or touch to plastic tooth while doing so or you could disfigure it. (If at anytime you mess up, don't worry, the friendly plastic is reusable, just put it back into the hot water and melt it again).
7. Follow steps #1 through #7 for your next tooth (or teeth).
8. After you have made a set of teeth, you may want to put them both into your mouth affixed to the teeth that they were made to fit onto, and while they are in place, melt another piece of friendly plastic and mold it to the roof of your mouth (while your FANGS are in place). This will create a "retainer" that will hold your teeth in place.
Color these Fangs
1. Soak your Fangs in COLD coffee. Hot coffee will melt your fangs.
2. Soak your Fangs in COLD tea. Hot tea will melt your Fangs.
3. (If you smoke, or know someone who does),... Blow cigarette smoke through and old white T-shirt (or cotton cloth), and then rub it on your Fangs until desired color is matched.
4. Myself, I used step #3 to color my Fangs, as I am a smoker, and it worked very well I must say. (I'm not saying that smoking is good).
Notes:
• Friendly Plastic is RE-USEABLE, so if you mess up don't worry. You can re-melt it over and over again and keep using the same piece if you want to.
• Results will vary from person to person, if you don't make a perfect pair on your first try, just keep trying and you'll get satisfying results sooner or later. It took me about 4 tries to get the results that I wanted.
• This is perfect for werewolves and vampires.
