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.

A method of preparing dental crowns efficiently and accurately, comprising the steps of
- a. preparing an analog dental crown mounting post which is a replica of an upper portion of a mounting post already or to be mounted in a mouth of a user, said analog dental crown mounting post having a downwardly extending elongated member with at least one removable and insertable radially extending anchoring extension within a bore disposed near a bottom end of said elongated member, said at least one extension passing completely through said elongated member;
- b. inserting bottom-end-down said elongated member into a dental crown casting mold;
- c. securing said elongated member temporarily in place within said casting mold;
- d. adding settable plaster molding material to said casting mold so as to embed said bottom end of said elongated member with said at least one extension by surrounding said bottom end of said elongated member with said plaster molding material;
- e. allowing said plaster molding material to set and harden with said elongated member and extensions embedded within said molding material;
- and
- f. utilizing said analog dental crown firmly anchored and secured to make a dental crown.
