An indirect-direct method of crown fabrication for existing removable partial denture clasps.

A technique that uses a combined indirect-direct method for the fabrication of a crown under an existing removable partial denture clasp has been presented. Advantages of this method are as follows: (1) The coping is placed directly on the preparation so the rest and retentive surfaces are more accurately developed than with other methods. (2) Fewer adjustments are required because of the accuracy of this method as compared with waxing the crown in one step.
