Wax pattern Flashcards
The ideal dimension for the luting agent space has been suggested at what?
“The ideal dimension for the luting agent space
has been suggested at 20 to 40 microns for each
wall, which implies that a complete crown
should have an internal diameter between
40 and 80 microns larger than the diameter of the
prepared tooth.”
when doing wax up its difficult to
look straight on teeth and detect any differences in depth of field

blue outer flame, hottest point of the flame
by heating shank the wax will float where
away form the hottest part of the instrument.
Inlay wax compiosition
all waxing, any kind of a casting
Paraffin (40 – 60%) Dammar Resin Carnuba Ceresin Candelilla Wax Beeswax Dyes
How many types of inlay wax are there?
Type 1 and 2
Type 1 wax inlay
Medium to hard in consistency
Generally used with the direct technique for making patterns in the oral cavity
Solid at 37 degrees C
Shrinks more than Type II Inlay Wax
Type 2 wax inlay
Softer
More commonly used in the indirect technique
Solid at 25 degrees C
Any wax that have a hgher solidification range will be
more prone to shrinking
if you cut the margin when waxing what happens?
The actual crown will have an over finished margin on one spot. Creates post op sensisitivty.
way to get dye off
one thumb and forefinger on dye, other thum and foreginger on wax pattern, its the pressure of the fingers pushing against each other that speartes them
proximal contacts narrow or broader is better
Broader in buccal lingual and occlusal gingival direction in generalis better and more robust contact
When doing embrasure wax up go broad ginigivally or not?
Yes keep embrasures full and broad even gingivally
Wax to a
centrum: allows for freedoom in excursive movements. So rather than having tripod cusp tip its ok to have cusp tip to flat fossa.
Waxing powder
helps determine contact. intesnes green color wherever contacts are
