Does Wonderpeg cause my E.max crown to have a lower value or become grey?
NO! Two things not related to Wonderpeg may be causing the problem.
1. E.max overglaze material comes in two types, Florescent and Standard. The Fluorescent glaze will cause the crown to be a lower value after the glaze cycle. If the lower value is not desired, the standard glaze material is recommended.
2. E.max ingot selection can be a little tricky. The HT (high translucency) ingots tend to be lower in value. As the pressing temperature is increased, so will the translucency resulting in a lower value. Some shades may require the use of the value ingot and color staining to produce the proper results.

Can Wonderpeg be used with e.max crowns?
Wonderpeg can be used with e.max crowns at normal temperatures. Generally, there should be little to no residue. If there is residue inside the crown, the methods below are recommended for cleaning out the residue.
1. Turn down the pressure and lightly sand blast. If you are a dental office without a large sand blaster, try purchasing an inexpensive pencil blaster for cleaning out the residue.
2. Use a gentle ultrasonic cleaner.
3. Use a tooth brush and water and lightly scrub out any residue.

Will any of the Wonderpeg contents cause the formation of bubbles during oxidation or during first or second layer opaque?
Wonderpeg would not under normal circumstances cause formation of bubbles. The only way Wonderpeg might cause the formation of bubbles is if the technician uses too much product and it is wrapping around the crown. Bubbles in the opaque are caused by metal contamination; improper metal finishing technique; improper casting technique; or start of drying time during opaque firing cycle.

Can Wonderpeg be used only to solder pieces or can
it also be used with zirconia and ceramic direct?
You can use Wonderpeg as a firing support for zirconia and ceramic. It can be used to directly support the coping. You can also solder with the product. However, if you have a large hole, you first need to use foil to get the shape of the die.

Any tips for how to solder with Wonderpeg?
Put a small piece of platinum or palladium (cheaper) foil in the hole fitting to the die (you can use super glue to hold it if necessary, but make sure you do not use too much), and then use the Wonderpeg just for support. It is better if the material dries out slightly. If the moisture from Wonderpeg gets on the area to be soldered, the solder will not stick. But if the technician is careful, it is not necessary to dry the material. The area to be soldered should be smooth and any substances should cleaned off. Use a graphite pencil to mark areas where the technician does not want the solder to flow. A small amount of flux is recommended on a gold crown. Heat the thickest part first near the area to be soldered and then move over in circular motion to the area that is thinner. Solder should flow towards the flame or hottest area which will be the thinnest. It will take little time for an area with a hole in it to patch.

How long must should the technician dry Wonderpeg?
If Wonderpeg is not dry enough, it may shrink a bit when fired which could be responsible for movement of the crown and therefore warping. The other possible reason for movement of the crown is if there is a bubble or air pocket in the placement of the product, then the crown will slump and distort. Make sure Wonderpeg is dry and that the product is packed in good with no air bubbles. Although a properly supported coping will not warp as easily, the primary cause is the use of a solder in which the flow temperature is too close to the melting temperature of the alloy. If the coping is overheated during soldering, the coping will warp even if properly supported.

Should Wonderpeg be refrigerated?
No, Wonderpeg should be stored at room temperature.
