[Our experiments with various preprosthetic surgical interventions]

Of 371 subjects hospitalized for preprosthetic operations during the years 1960-1972, 182 were re-examined on whom 228 preprosthetic interventions had been performed. The results obtained with vestibuloplasty associated with free skin transplantation, which had been executed mainly in the upper jaw, were very encouraging. To achieve a direct comparison of the method indicated by Schuchardt with the so-called buccal-inlay technique, both procedures have been performed simultaneously in a number of patients. Of the other preprosthetic surgical techniques, the plastic operation on the floor of the mouth yielded good results, too. If the relatively strict indications for the submucous vestibuloplasty according to Obwegeser were observed, this technique also proved satisfactory, whereas the results of the vestibuloplasty with healing by second intention and those of our restorative plastic operation on the alveolar crest were not satisfying.
