A prosthodontic assembly comprising:
- a restoration having a cavity defined by a first surface;
- an abutment positioned within the cavity;
- and
- a plurality of standoffs positioned in between the first surface and the abutment to provide a gap.
1 more element
A prosthodontic assembly comprising:
- a first prosthodontic component comprising an upper region with at least one recess, and
- a coping configured for creating a final restoration, the coping comprising a body portion having a proximal end, a distal end and an inner surface that defines an internal cavity and at least one standoff that extends from the inner surface towards a center of the internal cavity, the at least one standoff being configured to fit within the at least one recesses so as to prevent relative rotation between the first prosthodontic component and the coping, the at least one standoff also being configured to provide a gap between the inner surface of the coping and the upper region of the first prosthodontic component.
A prosthodontic assembly comprising:
- a coping having a cavity defined by a first surface;
- an abutment positioned within the cavity;
- and
- a plurality of standoffs positioned in between the first surface and the coping to provide a gap.

A prosthodontic assembly comprising:
- a final restoration comprising a body portion having a proximal end, a distal end and an inner surface that defines an internal cavity, the inner surface including a top region and a flanged region, and at least one standoff that extends from the inner surface towards a center of the internal cavity;
- and
- an abutment positioned within the cavity;
- wherein the at least one standoff and the flanged region are configured to produce a substantially uniform gap between the final restoration and the abutment upon which the final restoration rests.
