Purpose: The following chairside pickup workflow is applicable to cases involving implant supported locator overdentures. Agents can give this information to Drs who have questions.
Audience: CST
Dandy does not automatically provide overdenture attachment parts or housings with every case.
If your implant system is supported for overdenture parts, the attachment components will be available for selection directly within the ordering workflow. Parts can only be ordered from within that workflow.
If parts are not selected, Dandy will provide the denture that has holes to fit the housings into. The practice is responsible for supplying any required attachment components and housings.
See images of the housings and necessary equipment needed below:
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
Suggestions
Drill lingual exhaust vents for excess material connecting into relief holes
When placing auto-polymerizing material inside denture reliefs, set a timer or put some on your glove to test for polymerization
