## Abstract

A dental abutment coping or ring for securing a dental prosthesis to dental abutments. The coping or ring includes a body for insertion into a dental prosthesis, and a cavity or space sized to accept a head of the dental abutment. The interior surface of the cavity includes an interface region sized and shaped to accept the dental abutment in a retentive interface fit or a passive fit, depending on an angle of the interface surface. The exterior surface can have channels configured to contain a cement bonding the exterior surface to the dental prosthesis. A dental prosthesis system including the dental copings provides a retentive interference fit between the prosthesis and the dental abutments, even where the dental abutments are not parallel. A plurality of copings and abutments enables a retentive fit to varying degrees depending on the degree of interference fit in each coping and abutment.

## Claims

### Claim 1

A dental abutment coping for securing a dental prosthesis to a dental abutment, the dental abutment coping comprising:
a body extending from a first end to a second end along a longitudinal axis, the body defining a cavity extending from an opening in the second end of the dental abutment coping, the body comprising:
an exterior surface adapted to be inserted into a corresponding interface cavity of the dental prosthesis;
a peripheral region of the second end, the peripheral region extending around the opening and comprising a beveled surface oriented towards the longitudinal axis at an angle relative to the longitudinal axis; and
an interior surface sized to accept a head of the dental abutment, the interior surface having a tapered interior region and an interface interior region, the interface interior region being between the peripheral region and the tapered interior region, and the tapered interior region defining an increasing internal diameter of the cavity between a distal end of the cavity and the interface interior region.
