These partial dentures are made completely of acrylic plastic, which is coloured pink to blend with the gums and has the denture teeth bonded on. You may have heard these referred to as flippers. They are a more temporary version of a partial denture as they don’t have the strong metal sub-structure.
These partial dentures have a metal framework that is custom-fit to the arch and has clasps that fit around the existing teeth to provide retention. The pink acrylic is attached to the metal framework with denture teeth in the edentulous (missing teeth) area(s). This is a stronger partial denture that will last longer than the acrylic. It is often more comfortable as well because the metal structure is strong and therefore can be thinner than if that area were made out of the weaker acrylic.
The impression and fabrication of this complete denture is done when the gums and bone have healed completely (at least 6 months after the teeth have been removed).
The denture is made before the teeth are removed and then inserted in the patient’s mouth immediately after the teeth are extracted. During the 6 month healing period, the jaw bone and gums will shrink as a result of the teeth being removed. During this time, temporary or soft relines can be done to keep the denture tight an comfortable. We mix up and add a lining material to the inside of the denture which will mould to the jaw. A hard or permanent reline (which basically remakes the pink part of the denture) is needed after the 6 month mark as the healing is complete by this time.
