[The classification of anomalies of the maxillodental system].

Since the known classifications of maxillodental abnormalities are either not up-to-date or essentially differ from the WHO classification, the authors suggest a working scheme for classification of maxillodental abnormalities, that is based on the international classification of diseases. All the principal disorders of the maxillodental system structure are taken into consideration in the suggested scheme, that is, in fact, a clinico-morphologic and therefore pathogenetic classification.
