Study Notes
Waxes in Dentistry
- Wax is a solid substance at ambient temperature that becomes a low viscosity fluid when heated.
- Waxes are classified as natural, synthetic, or a combination of both.
- Natural waxes are derived from plants, animals, or minerals.
- Synthetic waxes are manufactured by a variety of chemical processes and are composed of hydrocarbons and/or esters.
- Natural waxes used in dentistry include beeswax, paraffin, and microcrystalline wax.
- Natural waxes are used for a variety of dental purposes, including processing, impression, and pattern waxes.
Processing Waxes
- Boxing and utility waxes are soft, pliable waxes used primarily in taking and pouring impressions.
- They are used to create a mold around the teeth to be replicated in a dental model.
Pattern Waxes
- Pattern waxes are used to construct the initial model of a dental restoration.
- Casting wax is used to build the framework of a removable partial denture.
- Inlay waxes, often used for crowns, inlays, or bridges, are carefully shaped to mimic the desired restoration size and form.
- Stress-relief in wax can occur when the wax is adapted at too low a temperature.
- Waxes, like most materials, expand when heated and contract when cooled.
- The thermal expansion and contraction of waxes can be slightly altered by blending different types of waxes, but this response to temperature changes cannot be completely eliminated.
