ADEX OSCE EXAM Questions with
100% Verified Answers Latest
Versions 2025 Graded A+
What muscle dictates the DL of the mand flange of a denture - Precise
Answer ✔✔superior constrictor muscle
how far to trim back the custom tray from the mucosal reflection -
Precise Answer ✔✔2 mm
occlusion rim heights - Precise Answer ✔✔maxillary 22 mm,
mandibular 18 mm
The inferior surface of the maxillary occlusal rim should be parallel to...
- Precise Answer ✔✔Camper's Line (Ala-tragus Line) and inter-
pupillary line
primary and secondary support for mand denture - Precise Answer
✔✔primary - buccal shelf, secondary - alveolar ridge
Posterior palatal seal - Precise Answer ✔✔extends through the hamular
notches, 2 mm in front of fovea palatinae, carried 5 mm anterior to the
vibrating line
,if denture falls down when smiling - Precise Answer ✔✔buccal notch
and buccal flange are excessively thick
Golden Proportion Ratio - Precise Answer ✔✔1.6:1:0.6
(central:lateral:canine)
S sounds like "th" - Precise Answer ✔✔either max anteriors are too far
palatal or palate is too thick. S sounds bring the max and mand closest
together (than other sounds)
Occlusal clearance gold - Precise Answer ✔✔1.5 mm functional, 1 mm
non-functional
Occlusal clearance PFM - Precise Answer ✔✔1.5-2 mm functional, 1-
1.5 non-functional
all ceramic clearance - Precise Answer ✔✔2 mm
Percentages for PFM copings - Precise Answer ✔✔high noble (98%
gold, platinum and palladium - these metals do not oxidize on casting),
Noble (50-60% palladium, 30-40% silver - silver will oxidize), Base
(70-80% nickle, 15% chromium - these both oxidize on casting)
Coping thickness - Precise Answer ✔✔noble metal is 0.3-0.5, base as
thin as 0.2
, Implant overdenture minimum space - Precise Answer ✔✔locator - 8.5
mm, ball and o-ring - 10-12 mm, bar clip - 13-14 mm
Polysulfide impression material - Precise Answer ✔✔rubber base,
setting time of 12-14 min
PVS - Precise Answer ✔✔poured up to 1 week, hydrophobic, do not
wear latex gloves, 6-8 min setting time, temperature sensitive (sets faster
in heat)
polyether - Precise Answer ✔✔impregnum, hydrophillic4-6 min setting
time, most stiff,
gypsum made of? types? - Precise Answer ✔✔calcium sulfate
hemihydrate; type I - rarely used, plaster of paris, type II - ortho casts,
not very strong, type III - dentures, type IV - use for stone dies, type V -
stone dies, most popular today
PDL types of elastin - Precise Answer ✔✔No mature elastin, 2 types of
immature: oxytalan (regulates vascular flow, parallel to root surface) and
eluanin
attached gingiva - narrowest bands - Precise Answer ✔✔buccal mand
canines and 1st premolars, lingual mand incisors and canines
