title: [The dentoalveolar junction].
abstract: A short survey on experiments carried out on human, dogs and models is presented. Special attention is paid to the periodontium. Registered deformation phenomena hint that the dentoalveolar system behaves as a reciprocally acting different elastic unit. This can be interpreted taking into account the mechanics of an anisotropic deformable matter. When the tooth is loaded, collagenous fibres of the periodontium are secondary activated to traction, in the course of which the fibrae alveolodentales apicales block dislocation of the apex radicis and not--as supposed in the past--getting out of the tooth from its alveolus.
