Indirect impression technique for multiple cast dowel and cores facilitated with three putty indexes

Fabrication of multiple direct cast dowel-and-core patterns is time-consuming and difficult because the clinician must assess the adequacy of the reduction of the final restoration and the path of insertion for the patterns. This article describes a technique for making impressions of multiple endodontically treated teeth for the indirect fabrication of cast dowel and cores, which are waxed up via three putty indexes obtained from the diagnostic waxup. This enables clinicians and technicians to communicate in a manner that facilitates predictable and consistent prosthetic therapy.
