RPD Review Questions
The impression and/or the cast may be inaccurate and thus be the cause of the problem. However, because of the time and cost involved in making the framework, all other possible causes should be eliminated before making a new impression. Scarring of the cast or sharp fins or protuberances on the framework might be correctable by analyzing the metal contacts with the teeth with some type of disclosing medium and relieving the metal. Inaccuracies from very minor tooth movement may also be corrected in this manner. If attempts to fit the framework to the mouth are unsuccessful, then one can assume that either the impression or the cast is inaccurate and the impression will need to be remade.
