Failure of a cast to seat properly on the cast during the restoration process can be due to various factors such as distortion during fabrication or changes in the cast material. To overcome this, the cast can be scraped with a sharp instrument to remove any excess material that may be preventing proper seating. Washing the casting with HCI (hydrochloric acid) may help to clean and smooth the surface, but it is not a common practice for this specific purpose. Forcefully positioning the casting can cause damage to the cast and is not recommended. If the discrepancy is more than 0.3 mm, it is generally advised to discard the cast and make a new one to ensure a precise and accurate fit.
