WHAT TO BRING ALONG?
Pliers & Wires
Wire Bending Exercise Book

1 Typodont with acrylic white teeth.
1 set of 018 slot Mini WICK Brackets bonded

ORMCO banded with Alexander 1st & 2nd molar bands, 018 slot

1 super glue
1 set cementation kit
1 "Stabilo" Waterproof Marker, M size, Black


TYPODONT SETUP

Please set up your typodont in class I or class III tendency, open-bite
All 1st molars are extracted
2nd molars and 3rd molars are mesially tipped.

Don’t forget to put back your bicuspids in place!

In clinical situation : Band the 2nd molars with the 1st molar bands
Band the 3rd molars with the 2nd molar bands

In a laboratory situation :

Replace the 1st molars with its attachments in the sockets
Replace the 2nd molars with its attachments in the sockets
One or two of the 2nd molars tipped forwards


NB: Buccal attachments of the mand. 2nd molars here in this case should be 171-0325
and 172-0325. An auxiliary slot may be used for up-righting spring.
