ABSTRACT:
The present invention comprises a dental tray having a base extending in a dental arch an arcuate distance at least sufficient such that a portion of one surface of the base is disposable generally above some of the occlusal surfaces and such that a portion of the surface of the base is disposable generally above some of the incisal surfaces in one operating position of the dental tray. A lingual sidewall is connected to one side of the base and a buccal sidewall is connected to the opposite side of the base, each sidewall extending a surface molding distance generally perpendicularly from the base and the sidewalls cooperating with the base to form a space for accommodating molding and impression material.
