Side effects
In individual cases, temporary irritation of the
mucous membrane or sensitivity of the teeth may
occur. These side effects usually subside within a
short time after the treatment 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
and monitors the whitening treatment. The patient
applies VivaStyle gel at home, after having been
instructed by the dental professional.
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. Well defined
trays will improve patient comfort and reduce the
chance of irritation of the mucous membrane.
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 – 1 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.
Instructing the patient
Careful instruction of the patient is fundamental to
the safe, effective application of VivaStyle tooth
whitening gel at home.
1. Review each individual step of the application
procedure in detail with your patient, using the
enclosed information on VivaStyle.
2. Check for an accurate fit of the tray.
3. Using a VivaStyle gel syringe, show the patient
how to fill the tray correctly. It is important not to
overfill the trays. The calibration markings on the
syringe should be used as guide when extruding
the material.
4. Show the patient how to insert the tray into the
mouth. Explain the proper procedure for removal
of any excess tooth whitening gel.
5. Determine how long the patient should wear the
tray. One hour a day is usually sufficient.
Depending on the individual requirements of the
patient, a longer wear time may be prescribed.
6. Explain the proper removal and cleaning
procedures for the tray. The tray should be stored
in the enclosed tray case.
