Q

What is centric relation?

A

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.

25
What position is independent of tooth contact?
CR
26
What is maximal intercuspal position?
– Position with complete intercuspation of opposing teeth.
27
What position is independent of condylar position?
maximal intercuspal position
28
What is a model?
reproduction for demonstration, accuracy not implied
29
What is a cast?
An accurate positive reproduction of the maxillary or mandibular arch
30
What is a diagnostic cast?
Cast for the purpose of diagnosis & treatment planning
31
What is a master cast?
Replica of teeth, residual ridges, & other parts of the dental arch used to fabricate dental restoration or prosthesis
32
What is a tooth-supported RPD?
RPD that depends entirely on natural teeth for support
33
What is a tooth-tissue supported RPD?
– RPD supported and retained by teeth at only one end. – Denture base is supported by teeth & the residual ridge
34
When should you make an RPD?
* Edentulous area(s) too long or numerous for a fixed prosthesis * Need to restore lost soft and hard alveolar tissue, especially in the anterior region * Reduced periodontal support of remaining teeth * Need to distribute masticatory stresses across the dental arch: cross-arch stabilization * No posterior abutment tooth * Attitude & desires of patient (economic considerations) * Immediate replacement of teeth
35
What are the disadvantages of RPDs?
* Removable, not considered ‘part’ of patient * May be lost or broken * Clasps may be visible, less esthetic * May dislodge during function * May trap food while eating
36
What is the height of contour on a tooth?
Line encircling a tooth that designates its greatest diameter at a selected position
37
What is a suprabulge area?
Portion of tooth above the height of contour
38
What is an infrabulge area?
– Portion of tooth below the height of contour – May also be referred to as Undercut
39
What is a kennedy class I?
Bilateral edentulous areas located posterior to the remaining natural teeth
40
What class?
Class I
41
What is a kennedy class II?
A unilateral edentulous area located posterior to the remaining natural teeth
42
What is a kennedy class III?
A unilateral edentulous area with natural teeth remaining both anterior and posterior to it
43
What is a kennedy class IV?
A single, but bilateral (crossing the midline) edentulous area located anterior to the remaining natural teeth

What is a modification space?
Edentulous areas other that those determining the classification.
48
What are applegates rules?
Eight rules governing the application of the Kennedy Classification system
49
Classification should follow rather than precede any ____________ of teeth that might alter the original classification
extractions
50
If a third molar is missing and is not to be replaced, it _______ considered in the classification
is not
51
If a third molar is present and is to be used as an abutment, it _____ considered in the classification
is
52
What do you usually do in an RPD if the first molar is present but the 2nd and 3rd aren't
Generally, if the first molar is present and the second and third molars are missing, the second and third molars are not replaced
53
The most _________ edentulous area (or areas) always determines the classification
posterior
54
Edentulous areas other than those determining the classification are referred to as _____________ and are designated by their number
modifications
55
The extent of the modification is not considered, only the __________ of additional edentulous areas is considered
number
56
There can be no modification areas in Class _____ arches
IV - Other edentulous areas lying posterior to the single bilateral area crossing the midline would instead determine the classification
