Abstract
An improved dental impression tray fabricated with vertical rests that anchor onto predetermined areas of the mouth to allow stabilization of tray while impression material sets. This disclosure also provides for a venting of selected teeth to the outside air to eliminate damaging force of vacuum on freshly cured material when tray is lifted. More specifically, the practitioner fills the impression tray with moldable material and seats fully into the mouth. Venting pins are immediately fitted through impression tray and impression material and seated onto the occlusal surfaces of the teeth. After the impression material has set, venting pins are removed. The impression tray is then lifted vertically and removed.
