Patent ID: 7204692

Claim:
A dental impression system comprising: one of a dental abutment or implant comprising: a proximal end, a distal end, and a collar positioned between said proximal and distal ends, said collar having an upper shoulder portion and a peripheral retention edge with an outer diameter, and an impression cap for coupling to said one dental abutment or implant comprising: a body having first and second ends and an inner cavity between said first and second ends, at least one of said first and second ends being an open end, a retention flange at said open end extending downwardly from the body in a direction generally parallel to a longitudinal centerline of the body, said flange having an inner retention surface engageable with said retention edge, said inner retention surface having a generally cylindrical configuration with a diameter slightly less than the outer diameter of said retention edge, such that, when the impression cap is fully coupled to said one dental abutment or implant, said inner retention surface forms a friction fit with said retention edge and a cylindrically shaped portion of said inner surface extends from said retention edge toward said distal end, and an inner angled surface located at the first end of the body, the inner angled surface having a size and an angle complementary to the upper shoulder portion and including an indentation, which defines a gap between the inner angled surface and the upper shoulder portion when the impression cap is coupled to the dental abutment or implant.
