ABSTRACT:
Disclosed is a dental arrangement and method for restoring broken teeth which require a crown and a retention post for securing the crown in a post hole formed in the tooth. The post hole is dimensioned to receive a first sleeve, which in turn is dimensioned to receive the retention post. By using the sleeve for confirming a desirable post hole size, and for centering the retention post during the making of the impression, a sufficient margin of error is built into the space between the post hole and the retention post to allow the placement of cement. A wax sealed second sleeve, with a short post therein, is used in making a die of the tooth.
