In removable prosthodontics we know partial and total dentures, which can be removed by patients themselves and cleaned every day with tap water.
Removable posthodontics is less popular with patients, because it is not totally fixed, even if it is correctly placed. The patients often feel that the denture is a foreign object in their mouths, because its size decreases their ability to taste food, and at first hinders the natural motility of the tungue and consequently talking. In addition to this the removable prosthesis is sometimes less aesthetical than fixed prosthodontic solutions.
For this reasons we choose removable prosthodontic solutions only when fixed prosthodontic solutions are not possible.
