Acrylic Removable Dentures

Affectionately known in dentistry as a “flipper”, this is the least expensive of all removable partial dentures. When a flipper is intended for temporary use while replacing one or more front teeth, it is often termed a ” stayplate”. Most frequently, these are intended to be used only for several months while awaiting healing during the various phases of implant placement. The pink plastic of the denture base is brittle acrylic, the same material used to make standard full dentures.
The largest single advantage to this type of RPD is that new teeth and new denture base can easily be added to an existing treatment RPD.If later in the course of treatment some of the existing natural teeth are extracted for any reason, new false teeth can be added quickly to the partial, maintaining the patient’s appearance. In spite of the fact that they are considered temporary solution, many people keep this type of appliance for many years, because as long as they are properly maintained, they look outwardly as good as the more expensive permanent appliances described below.

Flippers do have a number of disadvantages, however.

  • The acrylic denture base is somewhat brittle, and due to their irregular shape, these partials tend to break frequently, especially those made for the lower arch.
  • In order to counteract their tendency to break. The acrylic is usually built fairly thick which can take some “getting used to”.
  • The denture base rests only on the gum. And even though they are much more stable than full dentures, they are much less stable than the more permanent t RPD’s which are “tooth born“
  • As the gum resorbs, the false teeth tend to sink below their original level making it necessary to reline them frequently, and sometimes even to reset the teeth which adds to their expense.
  • Flippers are most frequently retained with wire clasps. They are frequently unsightly due to the limitations that pertain to their placement.
