ABSTRACT:
A dental tray is provided using a molded plastic. One form of tray includes buccal and lingual walls defining a series of recesses or indentations on opposed wall faces. When in use, a flexible impression support is applied to the walls and is coated with a suitable impression cement which enters the recesses and secures the impression support thereto.
After an impression has been taken, the impression support is stripped from the tray and a mold is made therefrom.
The use of recesses in the walls facilitates manufacturing of an inexpensive device of plastic using high speed, injection molding techniques.
