Q

What is required for to start treatment if the treatment plan included a complete cast crown?

A

diagnostic wax up and external surface form

25
What is today's project?
Diagnostic Wax-Up of tooth #30
26
Will wax stick to the cast if it is not fully dried?
No
27
Do this before adding wax to the cast:
create a retention hole
28
Check this after finishing wax-up of #30:
excursive and protrusive movements
29
What is the fabrication guide made from?
diagnostic wax up
30
Why do we fabricate the reduction guide directly on the typodont?
standardize amount of tooth reduction
31
What do we use for fabrication of external surface form?
silicon putty
32
At what 3 points should the reduction guide by sectioned vertically?
mesial cusps, lingual groove, disto-lingual cusp
33
What need to be locked when rebuilding the articulatory?
centric latches
34
True or False? Loosen the L centric latch to get L lateral excursion.
F. R
35
Which latch(es) need to be released for protrusive movement?
both
36
True or False? Some restorations use a dentinal pin.
T
37
What type of restoration is an inlay?
intracoronal
38
What type of restoration is an onlay?
extracoronal
39
3 general types or restorations:
intracoronal, extracoronal, full crown
40
When should a full cast crown be used?
Severe occlusal stress, odonticallly treated tooth, significant loss of coronal dentin
41
Is the treatment plan or diagnostic workup done first with fixed, complete-case prosthodontics?
diagnostic work up
42
For complex cases:
Wax Up first
43
Step in cutting tooth #30
identify crest of buccal cusp, pencil line vertically to buccal from the cusp tip to the gingiva, cut about 3mm of occlusal with e-cutter or arbor band retrace buccal cusp with pencil, cut retention notch with round bur, then wax up
44
Mesial buccal cusp tip of Max1M occludes with:
occlusal embrasure of opposite pair of maxillary teeth
45
Centric contact area:
distal inner slope of triangular ridge of DB cusp
46
DB cusp of Man1M
central fossa of opposite maxillary molar
47
What determines the maximum height of the ridges of #30?
the contour of the maxillary teeth
48
Which cusps should we build up first?
M and D buccal cusps
49
What type of bur is used to break inter proximal contacts?
conical bur
50
Red and green indicate differences in:
grit
51
What is used to clean e-cutters?
bur brush
52
Where do you start your preparation/
1mm above the CEJ
53
Gold Gauge:
thickness of crown and many hard materials
54
Range of degree of angulation:
5-25
55
Why are the 2 sizes for 5 and 10?
small and larger tooth
56
Range of angles for the 10 slot on the TOC gauge:
6-10 degrees
57
True or False? There is one TOC angle per tooth for a full crown restoration.
F. 2 MD and DB
58
When wouldn't you be able to use a reduction guide in the the clinic?
tilted restoration, fix tilt during diagnostic wax up
