dental trayA simple technique that helps to create ideal impressions is to use Scotch tape on the outer aspect of your slotted disposable trays. First, I suggest using Teledyne Master Trays, because while they are generally appropriate in size, they can be altered by heating the plastic and bending into the desired position. Once cooled, it will not rebound.

The use of tape prevents the impression material from continuing to ooze out of the slots. The tape stops the material and diverts it laterally to the outer aspect of the tray. I always brush all the internal aspects of the tray with adhesive as well, to help secure the material.

In addition to using Scotch tape on the outer aspect of the tray, I also place it on the distal aspects of the tray. Placing tape in the hamular notch and the retromolar pad areas prevents the impression material from oozing out, and confines ther impression material, minimizing the chance for pulls or distortions on the distal most tooth.

I love the ideas Bob. Do you have an opinion on digital scanning impressions such as the Trios Scanner?

brilliant- tape is easier and faster than the wax I've been using. Thanks!

I too would like to hear comments about ITiro compared to the cerac scanner

Is this for final impressions or for alginates also?

I used this method twice this morning. Once for a lower cast partial impression and the other for an upper crown and bridge impression. Both turned out excellent. Great technique.

You can use the technique for any type of impression.

How about adhesive backed wax as used in RPD construction. Much faster and more pliable and adhesive.

Are there any FDA considerations/restrictions on using this technique?

Why do we even care about FDA restrictions? Give me a break! This is a technique, not a product. What has happened in this country when we cannot think for ourselves?
