Dental implant abutment copings

A dental prosthesis system comprising:

• a plurality of dental abutments;
• a dental prosthesis including a plurality of interface cavities;
• and
• a first dental abutment coping, comprising:
• a body extending from a first end to a second end along a first longitudinal axis, the body defining a cavity extending from an opening in an open end of the first dental abutment coping, the body comprising:
• an exterior surface adapted to be inserted into one of the interface cavities of the dental prosthesis,
• a peripheral region of the second end, the peripheral region extending around the opening and comprising a first beveled surface oriented towards the first longitudinal axis, and
• an interior surface sized to accept a head of each of the plurality of dental abutments, 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,
• the interface interior region of the first coping comprising an interface surface substantially parallel to the first longitudinal axis;
• a second dental abutment coping, comprising:
• a body extending from a first end to a second end along a second longitudinal axis, the body defining a cavity extending from an opening in the second end of the second dental abutment coping, the body comprising:
• an exterior surface adapted to be inserted into one of the interface cavities of the dental prosthesis,
• a peripheral region of the second end, the peripheral region extending around the opening and comprising a first beveled surface oriented towards the second longitudinal axis, and
• an interior surface sized to accept a head of each of the plurality of dental abutments, 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, and
• the interface region of the second coping comprising a second beveled surface oriented towards the second longitudinal axis at an angle relative to the second longitudinal axis;
• wherein the plurality of dental abutments each comprises:
• a retention element with a base oriented towards an apical end of the dental implant and a shoulder oriented towards a coronal end of the dental abutment at an angle relative to a third longitudinal axis such that the perimeter of the retention element increases with increasing distance from the coronal end of the dental abutment through the region of the shoulder,
• a post extending from the apical end of the dental abutment to the base of the retention element, and
• the head extending from the coronal end of the dental abutment to the shoulder of the retention element.
