41
Branch of dentistry that pertains to the replacement of missing teeth and oral tissues:
Prosthodontics
42
What are the three different divisions of prosthodontics?
1. Fixed Prosthodontics
2. Removable Prosthodontics
3. Maxillofacial Prosthodontics
43
What branch of prosthodontics would be ensured in the following examples:
A patient presents with cancer in the upper arch in the molar region, that is resected by a surgeon that leaves a hole in the tissue/bone of the maxilla:
maxillofacial prosthodontics
44

A patient presents with a a cleft palate, resulting in a hole in the upper palate:
Maxillofacial prosthodontics
45
Artificial replacement of one or more teeth and/or associated structures:
Dental Prosthesis
46
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 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:
Abutment
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 articulate 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
A reproduction for demonstration, accuracy, NOT implied:
Model
65
An accurate positive reproduction of the maxillary or mandibular arch:
Cast
66
Cast for the purpose of diagnosis and treatment planning:
Diagnostic cast
67
Replica of the teeth, residual ridges, & other parts of the dental arch used to Fabricate dental restoration or prosthesis:
Master cast
68
RPD that depends entirely on natural teeth for support:
Tooth-supported RPD
69
Why are there not tissue-only-supported RPDs?
Because this would be a CD
70
- RPD supported and retained by teeth at ONLY one end
- Denture base is supported by teeth AND residual ridge
Tooth-tissue supported RPD
71
Also called an "extension based RPD"
tooth-tissue RPD

What are the indications for RPDs? (7)
1. edentulous area(s) too long or numerous for a fixed prosthesis
2. need to restore lost soft & hard alveolar tissue (especially in the anterior region)
3. reduced periodontal support of remaining teeth
4. need to distribute masticatory stresses across the dental arch (cross-arch stabilization)
5. no posterior abutment teeth
6. immediate replacement of teeth
7. attitude & desires of patient (economic considerations)
