Winged Impression Cap for Reduced Height Dental Impression Post
U.S. Patent No: 6,508,650 B2
An apparatus and method comprised of dental implant impression mounting hardware with a non-interfering, low profile for making time saving and accurate, simultaneous upper and lower impressions and bite registration, with the mouth completely closed and the jaw accurately positioned in centric closure. A low-profile, impression post is snapped within a matching low profile, winged and perforated impression cap held securely within a self-curing elastomeric impression material. The cured impression material retains the low profile impression cap which snaps free of the mating low profile impression alignment post. The impression post is removed and attached to an analog of the permanent endo-osseal implant and snapped back into low profile impression cap embedded in the elastomeric mold. This low profile assembly prevents interference with the taking of a simultaneous upper and lower elastomer impression of the accurately interdigitated jaw using a “triple tray” while insuring excellent registration.
