Locator overdenture (lower only)
Once the two implants have finished their healing period, abutments will be placed which will allow an attachment point for the lower denture. The connection between the abutment and the denture will limit the amount of movement of the lower denture. Similar to a complete lower denture, a locator overdenture rests on the patient’s soft tissue and is reliant on the soft tissue for support.
Benefits
limits the amount of movement during function of the denture
attachments are polished and easily cleaned
maintain bone support in the area of the implants
increased chewing ability compared to a complete lower denture
Drawbacks
removable prosthetic that is still tissue supported
denture sores can still exist
there will still be denture movement, especially tipping with function
same bulk as a complete lower denture
denture is not supported during the healing period
Maintenance
in-office cleaning of the abutments
abutments as well as the corresponding retentive gaskets will wear and require replacement
the denture teeth will wear over time and require replacement
denture teeth can fracture and require repair
the denture will require a reline as the tissue remodels
