Abstract
An abutment has a central portion between a post portion receivable in a dental implant and a head portion having a selected configuration. A shelf extending from the head portion outwardly to the central portion forms an angle alpha between approximately 0 and 30 degrees with an imaginary plane perpendicular to a longitudinal axis of the head portion to form a confluent joint with a crown of various emergence profiles thereon. A crown is fabricated, in certain embodiments, utilizing a sleeve having a negative image closely matching that of the selected head portion configuration. The finished crown is attached to the abutment, as by cement, polished and then inserted into the osteotomy site, angularly adjusted and locked in place using a seating device made by means of a seating jig.
