usually subside within a short time after the treat-
ment is finished or
discontinued.
Application procedure
The dental professional examines the patient's
medical and dental history, determines the
indication, prescribes the length of the treatment,
applies the whitening gel and monitors the
whitening process.
Step-by-step instructions
Pretreatment
Prior to the application of VivaStyle tooth whitening
gel, the patient's medical and dental history should
be carefully examined and professional tooth
cleaning carried out.
Tray fabrication
A properly fabricated tray will improve the
effectiveness of the whitening process. Snugly
fitting trays will improve patient comfort and reduce
the chance of irritating the mucous membrane. It is
advisable to use VivaStyle tray material only.
1. Take impression, fabricate a stone model and
trim it for optimal lingual adaptation.
2. Heat tray material on a vacuum former until it
sags 1 to 2 cm (0.4 to 0.8 inch), adapt to model
and place under vacuum for 30 seconds.
3. After cooling, remove tray from stone model and
remove excess material.
4. Carefully scallop the tray about 0.5 mm short of
the gingival margins, using either fine scissors or
a blade.
5. Place tray back on the stone model to assess
accuracy of fit. Final shaping and defining of
periphery may be accomplished with a coarse
acrylic polisher.
Application
1. Check for an accurate fit of tray.
2. Remove the cap from the resealable application
tip of the syringe by twisting it off. Place a small
amount of gel toward the facial side of each
tooth space in the whitening tray. Use the
calibration markings on the syringe as a guide
when extruding the material; a syringe usually
contains enough gel to fill approx. three upper
and lower trays.
Note: Do not apply too much gel into the trays.
Overfilling does not result in faster or better
results, and may cause sensitivity.
Reseal syringes that still contain whitening gel by
placing the cap back on the application tip.
3. Place the tray with gel over the patient's teeth.
Note: Do not squeeze the tray when inserting it.
4. Remove excess gel by means of a cotton roll or
tissue – prevent the patient from swallowing the
material!
5. Determine how long the patient should wear the
tray. Twenty to thirty minutes are usually
sufficient. Depending on the individual
requirements of the patient, the whitening
procedure may be repeated.
Note: The patient must not eat, drink or smoke
while wearing the tray.
6. Remove the tray after the whitening process has
been completed.
