Abstract
The present invention relates to a system of interchangeable impression coping for use with osseointegrated implant systems. The coping system will allow an accurate registration of the fixture head, abutement, healing abutment, or other prefabricated components to which the implant may be connected. The coping system also permits the direct substitution of each of the various impression copings within an index or impression, so as to transfer, translate or transform the relations and/or the type of component to a model adapted from an index or poured from an impression registered using the coping system.
Claims11
A system of interchangeable impression copings for use with osseointegrated implant systems, comprising:
- at least a first impression coping having a component fitting surface mountable to at least a first type of component connectable to an osseointegrated implant;
- and
- at least a second impression coping having a component fitting surface mountable to at least a second type of said component different from said first type;
- wherein said first and second impression copings are substitutable for each other within an impression taken using either of said first or second impression copings.
A configurable impression coping, comprising:
- a body with walls having opposing vertical slots of different lengths;
- and
- an outer casing fitting over said body and having inner spurs;
- wherein said impression coping is configurable to accommodate abutments of different sizes by orienting said spurs to engage selected ones of said slots.
A method for efficient fabrication of a prosthesis model, comprising:
- providing a range of impression copings, each having a component fitting surface mountable to a different type of component connectable to an osseointegrated implant;
- forming an impression using a selected coping of said range of impression copings;
- replacing said selected coping in said impression with an alternative coping of said range of impression copings;
- and
- forming said model utilizing said impression with said alternative coping.
