Abstract
Exemplary embodiments relate to a dental abutment and methods of forming the same. The abutment () may include a head portion () located at an upper end of the abutment and constructed to support a prosthetic tooth replacement and soft tissue adjacent the head portion, an anti-rotation feature () located at a lower end of the abutment and constructed to mate with a dental implant, and a fillet () located at an interface between the head portion and the anti-rotation feature. The fillet may reduce a risk of fracture at the interface between the head portion and the anti-rotation feature. In some examples, the abutment may be formed at least partially of a ceramic material.
