About modeling wax
Modeling wax on this shelf comes in tins and sets, in colours for the dentin, enamel and opaque parts of the pattern.
Modeling wax is a wax suitable for making patterns in the fabrication of restorations. Waxing is the contouring of a wax pattern, or of the wax base of a trial denture, into the desired form. The wax pattern sets the shape, size and contour of the restoration.
The FDA lists intraoral dental wax, used to construct the patterns from which metal prostheses are cast, as a Class I device (21 CFR 872.6890).
How modeling, carving, cervical and dipping wax and wax discs differ
- Modeling Wax — The wax that is added and shaped to build the pattern.
- Carving Wax — Sold as blocks and rods to be cut to shape.
- Cervical Wax — Used at the neck of the pattern, at or near the cemento-enamel junction.
- Dipping Wax — Kept molten in a bath; the die is dipped to make a coping pattern in one step.
- Wax Discs — A blank for the milling machine, not for hand waxing.
- Pattern Wire Wax — Ready-made wax shapes that are placed on the cast in place of free-hand waxing.
What to look at when choosing
Flow: under ANSI/ADA specification No. 4 a Type 1 wax may flow at most 1 percent at 37 °C, and Type 1 and Type 2 waxes must flow between 70 and 90 percent at 45 °C.
Shrinkage on cooling: cooling from 37 °C to 25 °C can contract inlay wax by up to 0.35 percent.
Distortion: a wax pattern can hold internal strains from the way it was worked, and it distorts when the strain relaxes. Time and temperature both make it worse, which is why patterns are generally invested immediately after they leave the die or cast.
