Twin Clasp – Provide Contour with Pre-Prep Model

ROE’s Twin Clasp Technique is a wonderful service for the patient who prefers not to give up their partial when fabricating a new crown under one of the clasps. When restoring this abutment tooth with a monolithic, milled crown, the impression protocol is simple.  If the tooth to be prepped is intact, capture a pre-prep impression to provide the contours, then a normal impression of the prepared tooth. With these two impressions, we will design a new crown with similar contours as the previous crown or natural tooth.
