[The characteristics of obtaining functional impressions under unfavorable conditions of the prosthetic bed of the edentulous mandible].

The results of treatment of 680 patients with a drastic atrophy of the alveolar portion of the toothless mandible evidence the advantages of the method for making functional casts, suggested by the authors. This method is based on anatomic features of the denture bed, topography and function of the mimic and masticatory muscles. Making of a preliminary cast is described in detail, as is the preparation of a model, making an individual spoon and the final functional cast.
