Alfa Triple Tray by Premier
The Alfa Triple Tray by Premier allows you
to take an upper and lower impression at the same time. It's an expansion
of the idea of the quadrant triple tray that has become so popular for
crown and bridge impressions. Designed by Dr. Jim DiMarino for taking
alginate impressions, it not only saves chair time, but it reportedly
reduces the gag reflex.
With a palate-free design, the Alfa Triple Tray allows the patient's
tongue to position itself to keep the material from flowing down the
throat. By keeping the tongue in a more natural position, Dental
Economics editor Dr. Joe Blaes claims that it actually
eliminates gagging (see "Pearls" in Dental Economics, June,
2003).Here's the technique. Mix the
alginate and load both the upper and lower at the same time. Place
the loaded tray in the mouth and instruct the patient to close. With
the patient closed on the tray, it isn't necessary to hold it. Wait
until the alginate is set, and remove it in the usual manner. You
now have an impression of both upper and lower arches. |

There are some tricks to the impression technique, and for this purpose
you can find a free tutorial at
www.dentrek.com.
You can buy the trays packaged with a trial pack on the outside so that
you can try the trays before you open the entire package--a nice idea to
help you see if you like them. They're made in three sizes: small, medium
and large, and can be purchased through your dealer.
The first use that comes to mind is for taking impressions for bleaching
trays. Using a fast-setting stone, you can have custom bleaching trays
ready for the patient in minimal time.
Besides alginate impression material, you may want to try the new alginate
alternative vinyl polysiloxane impression materials such as Status Blue by
Zenith/DMG or Position Penta by 3M Espe.
