Tray

TM

Separate alignment

sticks from each

other.

Assemble the cross,

making sure the

horizontal stick is

snapped all the way

down.

The hole of one alignment

stick is oblong and wi ll

only ﬁ t on one end of the

other stick. This makes

assembly goof-proof

Assembled align-

ment sticks.

The assembled sticks look

like this...

Fill both sides of

tray with adhesive

and polymer.

For best results, apply

tray adhesive ﬁ rst. Then

ﬁ ll the tray with polymer,

taking care to ﬁ ll the

retention tracks.

Fill the alignment

stick area with

polymer.

Fill this area with polymer

to hold the alignment

sticks. Afterward, you

will remove the alignment

sticks and the remain-

ing hole will form a tight

guide when the lab rein-

serts the sticks.

Insert assembled

cross into polymer

retaining area on

handle and locate

facial midlines.

After inserting the loaded

tray into mouth, ask the

patient to bite in centric

and relax the lips. Im-

mediately insert the cross

into the hole in handle and

locate the facial midlines.

Once located, seat the cross

completely and hold it there until

polymer is ﬁ rm and wait for ﬁ nal

set. Hint: use the pupils of the

eyes as a guide for the horizontal

midline and the bridge of the

nose and philtrum as the vertical.

Remove the sticks.

Remove the sticks and send

them along to the lab. After

pouring up the casts, the

sticks will be re-inserted

securely into the hole in the

tray handle thus allowing

the lab tech to mark the

facial midlines on the casts.
