Exam 10: Waxes

Pattern or casting waxes are used to fabricate:

In order to prevent residual stresses from forming:

Residual stress is stress remaining in a wax as a result of manipulation during heating,cooling,bending,carving,or other manipulation.Manipulation of wax puts molecules of the wax into positions that they like and can change because of their solid state.

The purpose of sticky wax is to:

Which of the following waxes may be used for bite registration?

The lost-wax technique uses _____ wax to produce crowns,inlays,and veneers.

Waxes:

Component waxes in dental waxes are usually _____ molecules with _____ molecular weights.

The flow of corrective impression wax at mouth temperature is ____%.

Which of the following is a plant wax that may be found as a component of inlay wax?

Organic molecules in waxes are composed primarily of long chains containing carbon,hydrogen,and oxygen.The long chains allow waxes to be flexible at room temperature or sticky as solids or liquids.

_____ wax is used as a wax veneer over an original impression to register the detail of soft tissues in a functional state.

Which of the following types of wax is used to fabricate wax patterns for crowns,inlays,and bridges?

Which type of wax may be molded around an unpoured impression to help contain the stone when it is vibrated into the impression?

Which type of wax is used to hold the position of denture teeth before the denture is processed in acrylic?

The _____ the coefficient of thermal expansion for waxes,the _____ the expansion as the wax is heated.

Which of the following statements is true of the property of flow for dental waxes?

Which of the following waxes are categorized as pattern waxes?

Sticky wax is:

At _____ temperatures,waxes hardly flow at all,but as the temperature approaches the melting _____ of the wax,the flow increases.
