Study Notes
Stages of Extractions
- Staging extractions are necessary in most cases
- Two-stage extractions are the treatment of choice
- Stage 1: Extract posteriors - leaving one posterior stop
- Save a posterior stop to have a reproducible occlusal reference
- Posterior stop also helps maintain vertical dimension of occlusion (VDO)
- Stage 2: When the denture is ready, the remaining dentition is extracted followed by denture insertion
- Stage 1: Extract posteriors - leaving one posterior stop
- Full mouth extractions are recommended for medically compromised patients who cannot undergo two-stage surgery
- In this case, the patient will have full mouth extractions without denture insertion and will be placed on a delayed interim/immediate denture
Treatment Workflow
- The treatment of choice is a two-stage extraction
- Save one posterior stop to act as a reference for bite registration
- Perform tooth setup and try-in based on the model
- Remove anterior teeth before setup and try-in
- Finalize immediate denture setup and wax up
Preliminary Treatment Plans
- Case #1
- Stage 1: Extractions of #5, 17, 28-32
- Stage 2: Extractions of # 6-11, 13, 20, 21, 23-26
- Case #2
- Stage 1: Extractions of #2, 5, 15, 18-20, 28, 29-31
- Stage 2: Extractions of #6, 11, 12, 21-28
Delayed Interims
- Average healing time before definitive reline, rebase or remake: 6-8 months
- Minimum healing time before a "delayed immediate/interim" denture: 6 weeks
Pre-Fit Instructions
- Pre-fitting the definitive prosthesis before the first stage extractions can save time
- Pre-fit intaglio surfaces and borders first to save time
- Occlusion can be addressed after insertion
Fitting the Prosthesis
- If the prosthesis does not fully seat after processing, potential errors include acrylic covering clasp arms, acrylic covering guide planes, acrylic covering undercuts, or inconsistent acrylic in other locations.
