The dental waxes may be composed of natural waxes and synthetic waxes. Gums, fats, fatty acids, and oils are also added to it.
Natural waxes are derived from mineral, vegetable, and animal origins. Synthetic waxes are chemically synthesized from natural wax molecules. They are typically composed of hydrogen carbon-oxygen and chlorine. Coloring agents are added into the wax for contrasts of wax patterns against tooth and model surfaces. Some formulations contain a compatible filler to control the expansion and shrinkage of the wax product. Most dental waxes contain 40 to 60% of paraffin by weight, which is derived from high boiling fractions.
