The Indirect Working Die Technique for Fabrication of Provisional Restorations

Publication ID Published Volume

This resource contains a 32-minute video that guides learners through the IWDT process. An instructor’s guide is also included to provide additional information. Whether a treatment plan calls for restoration of a single tooth or several teeth, provisional crowns or fixed partial dentures that occlude properly, have accurate margins, and have proximal contacts are needed to protect teeth during transition periods until final and definitive restorations are fabricated. These provisional restorations must protect vital pulp tissues. The making of these provisional dental crowns and fixed partial dentures can be facilitated by the indirect working die technique (IWDT). A provisional restoration that is made outside a patient's mouth with the IWDT can satisfy all biologic, mechanical, and esthetic requirements, and can be constructed with the use of accurate, flexible, elastomeric dies. The IWDT can be used to fabricate provisional restorations in advance of a patient’s dental appointment. It can also be taught to expanded-function dental assistants, freeing up the doctor to perform other procedures. Overall, use of the IWDT should increase efficiency and savings in treatment cost.

Educational Objectives

By the end of this session, learners will be able to:

  1. Fabricate accurate provisional restorations prior to the patient's appointment.
  2. Develop an understanding of the advantages of the indirect technique vs. the direct technique as it relates to marginal accuracy of restorations.
  3. Understand how elastomers can be used to fabricate working dies for use in the construction of provisional restorations.
  4. Develop a program for fabricating provisional restorations that can be utilized by dentists and expanded functionally to dental assistants in an office setting.
  5. Understand the time and cost-saving advantages of utilizing an indirect technique for making provisional restorations.
