[Problems of prosthetic treatment following preprosthetic measures in the maxilla]

The experiences with prosthetic treatment of the maxilla, following praeprosthetic surgery have been examined. It is of significance that this surgical intervention does not always result in a more favorable jawform and interalveolar relationship, factors which help determine the stability of the denture during mastication. The postoperative prosthodontic treatment of maxillary resorption remains problematical quite often becoming still more complicated because of additional problems in part undiagnosed by the dentist. Some of these problems and their solutions are discussed in a clinical case. The importance of denture stability during mastication independent of other retentive factors is emphasized as well as an occlusion coordinated with the "condyle in fossacentric" and the chewing strokes. The disregard of these stabilizing and retentive factors is too frequently the cause of praeoperative as well as postoperative failure in addition to contributing to accelerated residual ridge resorption.
