54
Q

What are the teeth with the clasp assemblies around them considered?

55
Q

Maxillomandibular relationship in which the condyles articulate with the thinnest avascular portion of their respective disks with the complex in the anterior-superior position against the slope of the articular eminence:

A

centric relation

56
Q

Centric relation is the maxillomandibular relationship in which the condyles articulate with the thinner avascular portion of their respective disks with the complex in the ___ position against the slope of the articular eminence:

A

anterior-superior

57
Q

CR is ____ of tooth contact

A

independent

58
Q

CR position is restricted to:

A

purely rotational motion

59
Q

The relationship of the condyle & disc in relation to the slope of the articular eminence; independent of tooth position:

A

centric relation

60
Q

What do we mean when we say CR position is restricted to purely rotational motion?

A

The mandible will be ONLY rotating around the condyle

61
Q

Position with complete intercuspation of opposing teeth; independent of condylar position:

A

Maximal intercuspal position (MIP)

62
Q

Maximal intercuspal position (MIP) Is ___ of condylar position

An accurate positive reproduction of the maxillary or mandibular arch:

A

Cast

Master cast

68
Q

RPD that depends entirely on natural teeth for support:

A

Tooth-supported RPD

69
Q

Why are there not tissue-only-supported RPDs?

A

Because this would be a CD

70
Q

A

Tooth-tissue supported RPD

71
Q

Also called an “extension based RPD”
