[Theory and practice in the taking of complete denture impressions]

The fundamental principles applicable to complete dentures are examined. Particular attention is given to the anatomical state of the so-called "biostatic areas" and the importance of a positive load: support ratio between the dental plate and biological tissue. The fundamental principles relating to the taking of impressions are discussed and stress is laid on the importance of imparting a functional character to the relief. Various techniques for the construction of a correct plate and their advantages and disadvantages are illustrated. Reference is made to preliminary impressions, resin spoons, the functional nature of the peripheral edges, and final impressions, with or without compression.
