(using the Pouring Jig)

1.  Insert die pins into RTP_Bases with finger pressure only. You are putting a tapered pin into a tapered hole, the more pressure you exert, the tighter the pin. A simple test is to wiggle the pin from side to side; if there is any play the pin is not fully seated.
Remember: Finger pressure only when inserting die pins.

2. The clear plastic sheets that are used when making the plaster index for the impression can be used over and over. Every so often you will need to rinse the plastic sheets to remove the plaster. It helps to keep them segregated by hanging each one on a small rack; otherwise, they will be hard to separate later when you are ready to reuse them.

3. If some of your accounts use the same metal impression trays over and over, you can label the plaster index with the name and size of the tray and save it for the next time you receive an impression in that tray.

4. To clean out small index holes on the bottom of the die surface, do the following: take a round, pointed toothpick and dip it in water, drop the water onto the hole and use the pointed end of the toothpick to work the water down into the hole and let it soak for a few seconds. Then take a high pressure air hose and blow the excess water out of the hole. This is the safest way to clean an index hole. Also, we have been told that a high pressure steamer works equally well.

5. Very few impressions will have the third molars, as most people have them removed at an early age. If the third molar is missing in the impression, very often the impression material will get in the way of the third molar pointer on the Pin-Locator. You can cut off about half of the third molar pointer on most Pin-Locators, but you may want to order some extra unaltered ones for those occasions when the third molar is included in the impression. This will save a lot of work trimming away impression material behind the second molar.

Hold the stone model and not the plastic base when separating a model from the impression, this will reduce chances of separating the stone model from the plastic base.
