Prosthesis replacing teeth in partially dentate arch- NOT designed to be removed by patient:
Fixed partial denture (FPD)
47
FPD:
Fixed partial denture
48
Is a hybrid implant restoration considered a FPD or a RPD? Explain:
FPD; only the dentist can remove the prosthesis- the patient cannot remove it themselves
49
Prosthesis replacing teeth in partially dentate arch designed to be removed by the patient:
Removable partial denture (RPD)
50
When you have a dental prosthesis that can be removed by the dentist, but not by the patient this is considered a:
FPD
51
Tooth used to support prosthesis:

52
Residual bone & soft tissue covering that remains after tooth loss:
Residual (edentulous) ridge
53
What may serve as part of support for certain types of RPD:
Residual (edentulous) ridge
54
What are the teeth with the clasp assemblies around them considered?
Abutment teeth
55
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:
Centric relation
56
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:
Anterior-superior
57
CR is ______ of tooth contact
Independent
58
CR position is restricted to:
Purely rotational motion
59
The relationship of the condyle & disc in relation to the slope of the articular eminence; independent of tooth position:
Centric relation
60
What do we mean when we say CR position is restricted to purely rotational motion?
The mandible will be ONLY rotating around the condyle
61
Position with complete intercuspation of opposing teeth; independent of condylar position:
Maximal intercuspal position (MIP)
62
Maximal intercuspal position (MIP) is ____ of condylar position:
Independent
63
The point of tooth contact when a patient is in CR position:
Centric occlusion (CO)
64
What position is seen in the following image?

Diagnostic cast
68
Replica of the teeth, residual ridges, & other parts of the dental arch used to FABRICATE dental restoration or prosthesis:
Master cast
69
RPD that depends entirely on natural teeth for support:
Tooth-supported RPD
70
Why are there not tissue-only-supported RPDs?
Because this would be a CD
71
-RPD supported and retained by teeth at ONLY one end
-Denture base is supported by teeth AND the residual ridge
Tooth-tissue supported RPD
72
What type of Kennedy Classification is seen in the following RPD?
