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 articular 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:

A

Independent

63

The point of tooth contact when a patient is in CR position:

A

Centric occlusion (CO)

64
Q

What position is seen in the following image?

A

MIP

65
Q

A reproduction for demonstration, accuracy NOT implied:

A

Model

66
Q

An accurate positive reproduction of the maxillary or mandibular arch:

A

Cast

67
Q

Cast for the purposed of diagnosis & treatment planning:

Master cast

69
Q

RPD that depends entirely on natural teeth for support:

A

Tooth-supported RPD

70
Q

Why are there not tissue-only-supported RPDs?

A

Because this would be a CD

71
Q

-RPD supported and retained by teeth at ONLY one end
-Denture base is supported by teeth AND the residual ridge

A

Tooth-tissue supported RPD

72

Kennedy Class III

73
Q

Also called an “extension based RPD”:

Tooth-tissue RPD

74
Q

What type of Kennedy Classification is seen in the following RPD?
