[Physiologic alveolar regression as a current parameter in geriatrics].

Gerontological findings, especially the biomorphotic become more and more important not only for scientific stomatology, but also for general stomatological practice and its priority dealing with the periodontal problems and, moreover, as a result, in turn, for application in geriatrics. The first part of the mostly theoretical foresight will be followed by the attempt of a practical method and of preliminary results supposing a future simplification in the sense of a pantomographic method according to Paatero for the measurement of the alveolar regression.
