Implant Supported Overdenture Without Extractions & Surgery Workflow

The following implant-supported locator overdenture workflow applies to patients with no existing dentition or appliance to establish their VDO and/or bite and requires a chairside pickup. 

Clinical Use Cases 

  • The patient lost or broke their Implant Supported Overdenture and cannot establish VDO.
  • Immediate-load of an Implant Supported Overdenture post-surgery. 

If your patient's treatment plan requires extraction of existing dentition and implant placement, please follow our Implant Supported Overdenture with Extractions & Surgery Workflow article. 

Case Setup Scan

APPOINTMENT 1 

  • Select the arch(es) that need a full denture to be fabricated. On the scanner order form, select: “Removables” > “Full Dentures” > “Printed/Milled.”
  • If facing difficulty scanning, doctors may take a standard impression and scan either the impression or the model. 

Register Bite 

APPOINTMENT 2 

Prepare the wax rim to be scanned:

  • After receiving the wax bite rim from Dandy, guide the wax bite rim into the patient’s mouth to get an accurate bite impression.
  • Apply light body wash to the wax bite rim for border molding and accuracy.
  • Clearly mark the wax bite rim with the patient’s smile lines, canine lines, and midlines.
  • Add blue mousse (or any other bite registration material) to register bite.
  • Take photos of the patient [highly recommended]: 
    • Head on photo with the patient smiling naturally (with wax bite rim in place).
    • 2 profile pictures (1 from each side) with the patient smiling naturally (with wax bite rim in place).
    • [If possible] A head on photo of the patient with cheek retractors in place (with wax bite rim in place). 

Wax Bite-Rim Scan

Scanning the wax rim:

  • Select the arch(es) that need a full denture to be fabricated. On the scanner order form select  “Removables” > “Full Dentures” > “Printed/Milled.”
  • When scanning arch(es) with wax bite rim(s) select “Denture” from pop-up.
  • Perform 360 extraoral scan of the wax bite rim(s) with the light body wash.
  • To obtain bite registration:
    • If single arch wax bite rim, scan with wax bite rim in mouth (from molar to midline) with blue mousse.
    • If dual arch wax bite rim(s), scan both arches in occlusion outside of mouth (full arch from molar to molar)  with blue mousse. 

Chairside Pickup Setup

APPOINTMENT 3 

  • 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.
