CLEAR CLONE CONCEPT DENTURE - part 3
Enter the Clear Clone Denture Technique (part 3) Clinical Technique
You have the C3 dentures back
from Drake.
Time to get impressions and
jaw relation records.
Be sure to have the following:
- Heavy body fast set PVS (I use Kettenbach Panasil)
- Light body REGULAR SET (I use Kettenbach Panasil)
- PVS adhesive (use same brand as impression material)
- Acrylic Burs
- Camera
- Disposable brush
- Perio Probe
It’s a good idea to try the C3s
in the mouth. Make sure they do not
impinge on any tissues. Its easy to look
through the clear acrylic and see if there are any heavy pressure points. Additionally, make sure the occlusion is
reasonably stable between the C3 and whatever it opposes. You don’t need perfect occlusion with 22
stops. Just a handful of contacts that
are stable and the C3 is not rocking about.
Adjust occlusion if needed.
Note the pressure points on the
mandibular along the premolar border areas.
It’s a good idea to relieve these with your acrylic bur.
Check border extensions. If you desire to extend borders, now is the
time. Use heavy body fast set in 2 or 3
increments to capture new borders. BE
SURE TO APPLY ADHESIVE TO THE BORDERS and onto the intaglio. (see the blue
adhesive in the photo)
This border molding was done in
two steps. The posterior palatal seal
and tuberosities and partway toward the peripheral frenula on each side are
first. Be sure to have the patient go
through all the oral calisthenics that we discussed a few Blog entries
back. Open wide, try to blow air through
your nose while I pinch your nostrils, and the ever popular “suck on my
finger”. Typically, I also place a small
dollop onto the rugae area to further refine a stop to avoid overseating the
tray.
Remove the C3 after border
molding and inspect. You can add
additional material if you fail to capture adequate borders. You can also cut back with the acrylic bur if
you have impingements/bleedthroughs.
PLEASE REMEMBER, this is a CLOSED BITE impression.
Even when doing border
molding, place the opposing C3 and have the patient close into full occlusion
during the impression procedures. It is
really easy to lose jaw to jaw relationship during impressions. This is particularly true if too much
material is placed during wash procedure.
Once borders are satisfactory,
Its time to do a wash impression. From
this point, you can use the same technique we discussed previously when doing a
denture reline. You will use a thin wash
of regular set PVS over the entire intaglio surface, have the opposing
appliance already in place and gently but deliberately place the wash laden C3
into the mouth. Have the patient gently
close into maximum intercuspation (it should be the same as you confirmed with
just the C3 in place). Once in place,
gently border mold and do all the border molding tricks you have up your
sleeve. (pinch nose and have patient blow, purse lips, “suck on my finger” etc)
Now repeat these procedures on the opposing arch.
When finished, take a
final bite registration and facebow.
This will give the lab all necessary information. Be sure to write a thorough prescription and
provide specific details of any changes desired that are different than the C3.
If midline is off, its easy to
score the new midline on the C3 and darken it with a Sharpie Marker. Be sure to take a photograph.
I find the C3 a very handy tool
for a variety of edentulous patient based treatment. If you learn this technique, it can create a
very efficient workflow for your cases, be them traditional dentures or full
mouth implant restorations.
