From Manual to Additive: Streamlining Dental Impressions
Udell previously used the traditional manual approach to make its removable partial denture frames (RPD). Using the impression taken by a dentist of the patient’s mouth, a skilled technician pours up the stone model and then duplicates it into a refractory model that will become part of the mold used to cast the metal RPD framework. The technician designs a wax pattern to the refractory model that will define the geometry of the RPD and ll in undercuts in the gums to provide a smooth path for putting on and removing the RPDs.
Finished parts, like this polished alloy frame, have higher accuracy using the digital method.
“The time required to print a typical removable partial dental frame is reduced by 80 percent, which makes it possible to complete the partial denture framework in a day and a half.”
