ABSTRACT:
There are disclosed jigs that are used in the present invention. These jigs are directed to hold and retain left, right and intra-proximal attachment forms prior to and during the soldering of the attachment to a crown. Each jig has a precisely formed head portion sized and shaped to receive and retain a mating engaging portion of the attachment so that the attachment is soldered in a predetermined position to the crown. The jig is made of a high temperature material and has a tail portion that is integral with and extends from the shaped head so that both the jig and the crown may be retained in an investment material during the soldering of the attachment to the crown. The attachments are used for bridges or partial restorations. Preferably the jig is provided with a scored surface to provide an improved gipping surface while imbedded in the investment material during soldering.
