Chairside Implant Supported Overdenture with Extractions & Surgery Workflow

The following workflow applies to patients who need their dentition extracted and replaced with an implant supported locator overdenture where a surgical guide is used. 

Patient Selection Criteria

  • The patient needs full extraction of their dentition on one / both arches.
  • A surgical guide is required for the placement of the implants.
  • Immediate-load of an Implant Supported Overdenture post-surgery. 

If your patient's treatment plan does not require extraction of existing dentition and implant placement, please follow our Implant Supported Overdenture Without Extractions & Surgery Workflow article. 

Key Workflow Steps

The outline below highlights the key steps for our implant supported overdenture and surgical guide workflow.

  1. Scan and Order - The doctor takes chairside scans and CBCT scans of the patient.
  2. Surgical Guide - Dandy provides a treatment plan and surgical guide to the Doctor.
  3. Implant Surgery - Implant Surgery and Tooth Extraction.
  4. Seat Immediate Denture - Immediate Denture seated.
  5. Seat Final Overdenture - Final Implant supported Overdenture seated.

Appointment 3

Before Chairside Pickup

  • Remove implant healing caps and place locator abutments; Verify abutments are above the tissue.
  • Apply blockout spacers to abutments.
  • Seat denture housings with black nylons onto each abutment to confirm passive fit of the prosthesis over the housing.
  • Verify reliefs by test fitting denture (using pip paste and a bur, reduce material if needed). Check the occlusion against the opposing arch.
  • Dry and clean denture thoroughly before adding material for chairside pickup to ensure material bonds properly.

Chairside Pickup

  • Place chairside auto-polymerizing material inside denture reliefs.
  • Guide denture in mouth, being sure to seat the denture all the way down. Have patient close into bite.
  • Remove once auto-polymerization is complete (follow manufacturer’s instructions).
  • If there are voids around the abutments, place additional material carefully so as not to get any inside the abutments.
  • Using a carbide bur, clean up any excess material on the intaglio and/or lingual areas.
  • Polish as needed for a smooth finish.
