[A preprosthetic-surgical solution for the extremely atrophic mandible].

Failures of reconstructing alveoloplasty, which are known from the literature and confirmed by the author's personal experience, are attributed to the intolerance of the load-carrying denture support. For this reason, it is suggested to perform an extra-oral intervention on the maximally atrophied mandible to reinforce its crest with autogenous bone. A second intervention is necessary in the form of a combination of floor-of-the-mouth revision and vestibuloplasty (method of Rehrmann), the load-carrying support remaining intact at the level fo the alveolar process.
