The first step in this is to place the molar brackets on the child typodont and then take an alginate impression with the brackets on. Remove the impression when it has set and if the brackets did not get removed with the impression, take them off the typodont and place them into the alginate. Next, pour the stone so it includes the brackets. What you will get is a poured up stone model with the brackets included. The idea is to keep the brackets from moving (IMMOVABLE) while you solder the wire in place. The next step is to bend the wire so the curve fits the lingual aspect of the anterior teeth. You want a smooth curve that touches all the anterior teeth. The idea is that this is used as a retainer to keep teeth from moving. (I think - someone correct me if I am wrong) We did this project in the middle of midterms and my concentration was on other classes. I also only have a few photos of the project.
After the wire is bent and placed you can hold in with some plaster.
When everything is straight and aligned you can now solder. Use flux and make sure everything is clean. You can use a torch or a bunsen burner for the joint. Make sure your wire is closer to the bracket than my picture depicts. I took this before any adjustments were made to the wire. You want it nice and close so the solder flows between the bracket and wire. I only have pictures of this and not the final product. So sorry. Maybe someone else can post pictures of their solder joints?
When you are done it should fit onto the junior typodont without any hassles. Make sure to polish the solder joint and make everything shiny before turning it in.
