ABSTRACT:
An inflatable dental tray for creating a dental impression. The tray is inflated for retention of an impression material that solidifies after a dental structure has been impressed therein. The inflatable tray can be configured for various inflation methods and in various shapes to form full or partial impressions. In one aspect of the invention the tray is inflated with impression material that flows from apertures forming a buildup. In another embodiment, the inflatable tray has a rigid support. Various additional inventive aspects include an exterior filled inflated tray and fill tubes that provide for proper mixing of impression material.
