The Indirect Working Die Technique for Fabrication of Provisional Restorations

Abstract 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
