How Supplied

Sticks, pellets, and tins

Composition

Can be a mixture of different waxes, such as paraffin, carnauba, ceresin, and beeswax

Armamentarium and Directions

• This dental material is used in a dental laboratory setting and arrives to the dental office as a custom order.

 

imageSpecial Notes/Helpful Hints • Inlay wax is used to produce patterns for metal casting through the lost wax technique. • At its working temperature, inlay wax possesses low flow to prevent distortion of the wax pattern. • During the lost wax technique, inlay wax must burn out with no residual because residual material would interfere with casting of the pattern.

How Supplied

Sheets and preformed shapes

Composition

Can be a mixture of different waxes, such as paraffin, carnauba, ceresin, and beeswax

Armamentarium and Directions

• This dental material is used in a dental laboratory setting and arrives to the dental office as a custom order.

 

imageSpecial Notes/Helpful Hints • Casting wax is used to construct the wax pattern for the metal framework of a partial denture. • Casting wax comes slightly tacky to help hold the material in place on a gypsum cast. • At its working temperature, casting wax possesses low flow to prevent distortion of the wax pattern. • During the lost wax technique, casting wax must burn out with no residual because residual material would interfere with casting of the pattern.

MATERIAL

How Supplied

Sheets (7.5 cm wide, 15 cm long, and 0.13 cm thick)

Composition

Ceresin, beeswax, carnauba wax, and various synthetic waxes

Armamentarium and Directions

• This dental material is used in a dental laboratory setting and arrives to the dental office as a custom order.

 

imageSpecial Notes/Helpful Hints • Baseplate wax is used to build the contours of a denture and hold the position of the denture teeth before the denture is processed in acrylic. • This material can also be used to take a bite registration for articulation of study casts. • The composition of baseplate wax can be altered to give varying hardness. Examples are as follows: Type I is a soft wax at room temperature and is used for contouring a denture. Type II is a medium wax that is used for patterns that are placed into the mouth in a temperate climate. Type III is a wax with flow qualities at a functioning temperature similar to inlay wax. • Residual stress on the baseplate wax during handling can move teeth and change the occlusion of the denture. • At its working temperature, baseplate wax possesses low flow to prevent distortion of the wax pattern. • During the lost wax technique, casting wax must burn out with no residual because residual material would interfere with casting of the pattern.
