[Our experiences with a removable partial prosthesis as a preventive therapeutic device].

On the basis fo follow-up examinations, the author points to essential features on which the preventive action of the cast removable partial prosthesis depends. Frequently encountered periodontal diseases are caused by clasps and covering components of the denture base. Traumatic occlusions occur independently of the duration of wear, which is indicative of the dentist's inadquate attention. Metaphylaxis associated with adjustment of the prosthesis to the changing masticatory organ is the main prerequisite for long-term success.
