Abstract: An improved endo-osseous apparatus for dental plates is described which comprises a series of blades for the anchoring to the osseous tissue of the gums. The upper portion of each anchoring blade is formed by a projecting threaded pin of small diameter, provided with a movable or fixed cap or bush and with an internally threaded hollow element adapted to be screwed onto the pin. A ferula is provided with through holes, for insertion of the pins. The anchoring blades are fixed to the ferula by means of threaded hollow elements or knurled nuts which are screwed to the pin. The threaded hollow element may be a frustum conical cap, with the end zone flap-enlarged and having the same diameter as the cap or bush.
