Remember: The first 6 pages of this chapter in the syllabusare a
nice overview of record making and materials.

HAND ARICULATE IN CO
No recording material needed as you have STABLE natural tooth
contacts around the arch. The more likely situation would be one
that has molarcontacts on both sides of the arch. Dont use elastics
to tie these casts together!
Use wooden sticks that are sticky waxed to all 4 sides to ensure
no movement.

ARTICULATE WITH RECORDING MATERIAL IN CO
You have relatively stable natural contacts but require
recording materialto ensure your articulation is as stable as
possible. Increase in edentulous areas and/or less stable contacts
from the previous.

ARTICULATE WITH RECORDING MATERIAL AND WAX RIMS IN CO
Edentulous areas have increased in size while natural tooth
contacts decreaseor you have distal extension areas. The need for
wax to to support the recording material to ensure greater
accuracy.Still in a CO position and keep your eye on the natural
tooth contacts you are
using for reference. IE: DONT COVER YOUR ANTERIOR TOOTH
CONTACTS!

ARTICULATE WITH RECORDING MATERIAL AND WAX RIMS IN CR
Normally used when you have a CD/RPD with wax rims in all
posterioredentulous areas. May also be used when you have RPD/RPD
with fewnatural teeth remaining and will restore in CR.When I make
my CR record I first use Aluwax in the anterior for my CR recordan
then once Im sure Im recording in a repeatable position I go back
and add
Exobite in the posterior and just make sure the lower tooth go
back properly intomy Aluwax record.
