DENTAL DEVICE FOR RIDGE PRESERVATION AND PROMOTION OF JAW BONE REGENERATION IN AN EXTRACTION SITE

Dental device (1) for ridge preservation around the socket (2) of an extracted tooth and for promoting jaw bone regeneration inside the socket (2) of the extracted tooth. The dental device (1) comprises: a screw (3) which is entirely made of a biodegradable material to eliminate the need for a removal surgery, wherein the screw (3) is adapted for tight fixation within the jaw bone (4) in the socket (2) to prevent micromovements during bone-tissue regeneration, wherein the screw (2) has a length such that its top is, in the inserted state, flush with the alveolar ridge (5) around the socket (2) to promote full bone regeneration inside the socket (2), and wherein the screw (3) has a hollow (6) and pores (7) to allow blood perfusion into the hollow (6) for formation of blood coagulum to serve as biological matrix for bone growth inside the socket (2).
