ABSTRACT:
A method and confirmation device for making an accurate impression of the upper or lower teeth, implant and gum assembly in which the device includes a cylindrical section having one end temporarily attachable to the exposed threaded end of the implant and a second end having an opening to receive a guide pin. An elongated wing extends tangentially from the cylindrical surface perpendicular to the axis of the cylinder so that when the cylindrical section is attached to the implant, the wing extends along the gum line and has an end that is rigidly attachable to the cylindrical section of a neighboring confirmation device. A rigid metallic frame is thereby established which serves as a foundation for impression material molded in a dental tray around the frame and dental process comprising the implants and remaining teeth and gums. The frame prevents distortion of the impression material, thereby providing that the molded impression is an accurate form with which a master model of the finished dentures can be made.
