title: Interim dentures and treatment dentures.
abstract: Improvement in the interim denture procedure in the past decade has been one of the significant advancements in prosthodontic practice. The interim denture approach is only slightly more time-consuming and expensive than the conventional immediate denture approach, yet it has many advantages. Among those advantages are the following: (1) allows rapid results; (2) results in a higher quality definitive denture; (3) allows the surgical treatment to be performed during one appointment; (4) permits duplication of the natural tooth position; and (5) provides the patient with a spare denture after the definitive denture is completed. An interim denture technique was described that utilized a flexible layered silicone mold to form the replaced teeth. The interim denture procedure is flexible and lends itself to many variations in technique to meet unusual clinical situations. An interim removable partial denture technique was described that involves block-out of undesirable undercuts and duplication of the master cast for fabrication of the partial denture. This technique results in an interim partial denture that can be placed with little or no adjustment and that will provide better service for those who require it. Three simple procedures for fabricating treatment dentures were described and the indications for each were discussed. Although treatment dentures are not often used, they are essential for the dentist who is treating difficult patients who require complete dentures.
