title: Changes in shape of posterior parts of upper jaws after extraction of teeth and prosthetic treatment.
abstract: Changes in the sagittal and transverse profiles of the anterior and posterior parts of the alveolar process after extraction of all teeth and insertion of immediate dentures were studied during a five-year period using casts of 14 patients. The casts were oriented in a uniform way with the help of reference points in the hard palate. The desired profiles could then be reproduced with a special tracing apparatus. Four profiles made during the five-year period were compared for each patient. Changes in shape of the upper jaws in the median sagittal plane agreed well with the results obtained in earlier investigations and showed a reduction of the anterior part of the alveolar process for each patient. In the posterior part of the upper jaw, on the other hand, an increase in size was seen in the transverse section of the alveolar process in most patients examined.
