title: [The retention of plastic filling materials with various lining materials and technics].
abstract: In "tensile strength" tests an attempt was made to find out whether a material and/or the type of preparation of the cement base and/or a specific filling technique have any influence on the retention of a permanent filling in a cavity prepared according to Black's principles of preparation. The following was found: 1. Amalgam fillings placed on hardened cement bases did not show any differences in their retention behavior. The type of the protective base material was of no importance. 2. Fillings rapidly inserted according to Robiczek's method showed considerably higher retention values. 3. The filling material combines with the cement base only in rapidly inserted fillings which considerably contributes to increased retention.
