[Special considerations in the prosthodontic treatment of the elderly].

A particular problem in the prosthodontic treatment of aged persons is their diminished ability to adapt to changes. Consequently, this requires an incremental treatment plan for changes in the mouth. In many cases it is preferable to modify an existing denture step by step instead of constructing a new one. Where extractions are necessary, immediate replacements should be provided, if this aids the patient stereognostically. The extraction of all remaining teeth should be done in a prolonged step-by-step procedure and with the use of an extendible denture. Continued care is imperative. Important factors to be considered are denture maintenance, esthetics and the multimorbidity of the geriatric patient.
