Abstract: The present invention relates to a method and an apparatus for obtaining an artificial alveolus for a pin with a spheric head supporting at least one tooth root or, in connection with a similar device, a bridge carrying more teeth, the apparatus being provided with at least one root assembly. The artificial alveolus is formed by a body with two portions integral with each other. Between the spheric head pin and the alveolus an elastic covering is provided and is capable of being deformed in order to allow springing and slight oscillations of the spheric head pin with respect to the alveolus. Each root assembly is obtained in a body provided with a vertical threaded bore opened upwards.
