A Short Note On Overdentures....with ppt for download.


A complete or partial removable denture supported by retained roots that is intended to provide improved support, stability, and tactile and proprioceptive sensation and to reduce ridge resorption.

  Preserve alveolar ridge
                -retention (eventually)
                -stress distribution
·                      Poor oral hygiene
                             -caries and periodontal disease
  Soft tissue undercuts
  Breakage of denture
                -stress concentration over abutments

Selection of abutment teeth
  One per quadrant
  Not adjacent teeth
  Usually mandibular cuspids and premolars
  Maxillary cuspids frequently cause esthetic and retention problems due to soft tissue undercuts

  Regard as transitional
                        - need perfect oral hygiene
                        -daily non acidulated topical fluoride (sodium fluoride)
  Probably better to place 2 implants
