17
Q

True or false.

For direct wax techniques, type I inlay wax must soften at the temperature that is not hazardous to the pulp tissue and it must harden at the temperature above mouth temperature.

A

True

18
Q

True or false.

The colors of inlay waxes should contrast with the hues of teeth and dies

A

True

19
Q

True or false.

The colors of inlay waxes should contrast with the hues of teeth and dies

A

True

20
Q

Dental waxes are supplied in a variety of colors, what are those colors?

A
  • Blue
  • Green
  • Yellow
  • Red
  • Ivory
21
Q

Why are the colors of inlay waxes are useful?

A

To provide a suitable contrast against a die that is an accurate replica of a prepared tooth.

22
Q

What wax that is useful for aesthetic case presentations to patients?

A

Ivory-colored wax

23
Q

True or false.

Inlay waxes may be softened over a flame or in water at 54°C to 60° C to enable their flow in the liquid state and their adaptation to the prepared tooth or die.

A

True

24
Q

True or false.

A regular or soft type of wax is typically used for indirect work at room temperature or in cool weather a harder or medium type with a low flow property is indicated for use in warmer climates.

A

True

25
Q

Used to fabricate wax pattern for crowns in lace and bridges.

A

Inlay wax

26
Q

It contains different waxes such as paraffin ceresene carnoba and beeswax

A

Inlay wax

27
Q

What is the first procedure in the casting of an inlay or crown for the lost wax process?

A

The preparation of a dental wax pattern

28
Q

What is the difference when a wax pattern is made in the mouth versus a pattern that is made outside in the mouth? (Indirect and direct)?

A

A wax pattern made in the mouth (direct technique) will shrink appreciably as it is cold to room temperature.

A wax pattern made by the indirect method may not shrink as much.

29
Q

Why does the direct technique is rarely used in producing wax inlay patterns?

A

It is because of the wax sensitivity to changes in pressure temperature and heating and cooling rates during manipulation because the direct technique will shrink as it is cooled to room temperature

30
Q

Are used occasionally to facilitate the wax pattern preparation process this wax is kept molten to provide a station for mass production of patterns.

A

Dipping waxes

31
Q

Is a medium wax employed in direct techniques

A

Type I

32
Q

Is a soft wax used in the indirect techniques

A

Type II

33
Q

True or false.

No matter how a pattern is prepared it should be an accurate reproduction of the missing tooth structure or part of a prosthesis that is adapted to soft tissues the wax pattern forms the outline of the mold into which an alloy is a cast or a ceramic is hot isostatically pressed.

A

True

34
Q

True or false.
The pattern should be well adapted to the prepared cavity or replica cavity and properly carved without any significant distortion.

A

True

35
Q

After the pattern is removed from the prepared cavity it is in case in a gypsum or phosphate based material or other type of refractory material known as INVESTMENT. This process is called?

A

Investing the pattern

36
Q

True or false.

After investing anatomically accurate wax or resin patterns for inlays, onlays, crowns, bridges, and frameworks for removable partial dentures the invested material must be eliminated for completely before molten metal is cast or course ceramic is hot pressed into the mold cavity.

A

True

37
Q

The hardest and are for math use in tropical climates.

A

Type III wax

38
Q

A soft pliable waxes used primarily in taking and pouring of impressions. Supplied as long 40 cm strips that are 4 to 5 cm wide and 0.1 cm thickness.

A

Boxing wax

39
Q

Use the around the periphery of an impression trait to reduce irritation of the tray on the soft tissues or to extend the tray before the impression is taken.

A

Utility wax

40
Q

It is brittle at room temperature and sticky when heated it is used to assemble metallic or rest in pieces temporarily in position or to seal a plaster splint to a stone cast in the process of forming porcelain facings.

A

Sticky wax

41
Q

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

A

Corrective impression wax

42
Q

Used for accurate articulation of certain models of opposing arches.

A

Bite registration wax
