Q

____ cast is mounted to the correct axis by a facebow transfer

A

Maxillary

17
Q

____ cast is mounted in centric relation position to the maxillary cast

A

Mandibular cast

18
Q

The casts are mounted at the correct ______ distance from each other to allow the teeth to be arranged, bases are placed in mouth and teeth occlude at this ____ dimension

A

Vertical

19
Q

To make sure the maxillary baseplate stays in place during interocclusal bite registration, sprinkle a small amount of ______ powder on the tissue side of the denture

A

Denture adhesive powder

20
Q

T/F: Denture adhesive must be removed from cast before placing the record bases on master casts to avoid denture processing errors

A

True

21
Q

Both rims have a ______ carved in to achieve a useful bite registration; ensures stability in a lateral direction

A

V-shaped grooves in the molar region

22
Q

the 2 phases of ensuring _____ are Getting entire mandible retruded using bi-manual technique; positioning the condyle-disc assembly in the uppermost anterior position?

A

centric relation

23
Q

Should contact occur between the wax rims or bases during bite registration?

A

No

24
Q

T/F: The importance of accurate interocclusal records and accurately mounted casts merit extra time practicing with patient

A

True

25
Q

Resiliency of the tissues supporting the denture bases, stability and retention of record bases, TMJ and ints neuromuscular mechanism, technique employed in making the records, amount of pressure applied in making the records, and skill of dentist are factors that affect _____ record

A

Centric relation

26
Q

____ is the instrument that carries the relationship between the maxillae and condyles from the patient to the articulator

A

Facebow

27
Q

____ facebow uses an arbitrary axis (external auditory meatus) to approximate rotational centers of mandible

A

Arbitrary facebow

28
Q

_____ facebow uses the transverse hinge axis; used in fixed procedures; locates exact hinge axis points on skin then transfers cast to articulator in accurate relation to these points

A

Kinematic facebow

29
Q

The purpose of the ____ is to orient the max cast to the articulator in the same relationship to the opening/closing axis of the articulator as exists between the maxillae and the opening/closing axis of the TMJ of the patient

A

Facebow
