Abstract
A dental impression tray assembly includes an impression tray as well as a liner. The liner is adapted to cover holes in the impression tray in order to prevent leakage of impression material through the holes during a dental procedure. Preferably, the liner is removably connected to the tray so that the practitioner has the option of using the tray with or without the liner.
