ABSTRACT:
The device is distinctive in that tooth (D) and matching adapter (A) are both designed with matching shapes to allow, after assembly, the formation and definition of one or more spaces (V) of variable shape, as appropriate, the adapter and tooth being made with one or more openings allowing the filling and application of a special-purpose material (M) in the above-mentioned space(s), said special-purpose material fulfilling the functions of locking the tooth relative to the adapter by absolute contact between the tooth and adapter by forming a contact cushion that ensures distribution of the stresses and strains in all the areas filled by the material.
