Abstract
An implant analog includes an abutment that can be mounted in the dental lab replica of the relevant section of a patient's mouth more securely than heretofore possible. Because of the implant analog, a crown will attach more accurately to the implant in the patient's mouth. The analogs have a pin or other protrusion that projects from the base of the analog. The analog has substantially the same height and dimensions as a conventional implant and abutment.
