1.1. Immediate Dentures

1.1.1. Introduction

Definitions: (from the Glossary of Prosthodontic Terms, Fifth Edition, 1987)

  • Immediate denture/overdenture: A complete or removable partial denture or overdenture fabricated for placement immediately after the removal of natural teeth
  • Interim immediate denture: A dental prosthesis to be used for a short interval of time for reasons of esthetics, mastication, occlusal support, convenience, or to condition the patient to the acceptance of an artificial substitute for missing natural teeth until more definitive prosthetic therapy can be provided.
  • Overdenture, overlay denture: A prosthesis that covers and is partially supported by natural teeth, tooth roots, or dental implants

1.1.2. Types of Complete Immediate Dentures at TUSDM

  • Interim immediate denture - FDTD/U or L
  • Conventional immediate denture - FDID/U or L

1.1.3. Two Types of Treatment Plans at TUSDM

  • Conventional immediate denture (FDID/U or L) followed by a reline (FDRB/U or L)


  • Interim immediate denture (FDTD/U or L) followed by a second denture (FDUP/U or L)

1.1.4. Comparison of the Conventional and Interim Immediate Denture Techniques

Conventional Interim
Definitive Transitional
Intended as the final or long term prosthesis Intended for short term use only
After healing, it is relined with acrylic resin After healing, a second denture is made
Indicated when two extraction visits are feasible Indicated when only one surgical visit is preferable to maximize insurance benefits
Possibly indicated for Medicaid patients as Medicaid allows denture treatment and denture reline treatment Contraindicated for Medicaid patients as Medicaid will not cover the cost of two dentures
The esthetics of the denture cannot be changed The second denture procedure allows an alteration of esthetics, and all other factors, if indicated
At the end of treatment, the patient has one denture At the end of treatment, the patient has a spare denture to use in case of extenuating circumstances
If all posterior teeth are initially removed, vertical dimension of occlusion is not preserved. (However, opposing bicuspids can be maintained.) Since posterior teeth need not be removed, vertical dimension of occlusion may be preserved
Contraindicated for patients who will need complicated treatment plans involving both arches, such as periodontal therapy, crowns and fixed and partial dentures and dentures opposing removable partial dentures Often indicated when the patient will become edentulous in one arch and become partially edentulous in the opposing arch for the first time. An interim complete upper denture can be made. Then any periodontal procedures, crowns and fixed partial dentures, can then be done during the initial healing stage
