<p>A stable dental prosthesis system includes transparent guides (240, 250, 260) with radio opaque markers (242, 262, 263) therein to accurately position an implant (220) in a jaw. To make the prosthesis for the implant (220), an implant analog (320, 420, 520, 620, 720) is used with an abutment (1020) that can be mounted in the dental lab replica of the relevant section of a patient's mouth securely. The analogs hava a pin (312, 2012) or other protrusion that projects from the base of the analog. The system also includes a perforated tray (2101) for accommodating protruding implant impression copings (2123) therethrough when the impression mold is made of the dental patient's mouth. A generally flat articulation wafer (2301) connects one impression of one jaw to an opposing wax impression of an opposite jaw, so that upper and lower prosthesis are in positional register. A flexible frame may also be provided for temporary teeth before osteointegration of the implant with the jaw bone.</p> |
