Dental device for alveolar ridge preservation at tooth extraction site and to promote jawbone regeneration

摘要

The present invention relates to a dental device (1) for preserving the alveolar ridge around the extracted socket (2) and for promoting jawbone regeneration in the extracted socket (2). The dental device (1) is characterized by comprising a screw (3) made entirely of biodegradable material to eliminate the need for removal procedures, where the screw (3) is undergoing bone tissue regeneration. It is adapted to be firmly anchored in the jawbone (4) of the socket (2) to prevent tremors, and a screw (3) is inserted to promote bone regeneration that fills the socket (2). In its original state, its head has a length that is coplanar with the alveolar ridge (5) around the socket (2), and the screw (3) is biological in bone growth within the socket (2). It has a depression (6) and a pore (7) that perfuse the depression (6) with blood to form a blood coagulum that functions as a matrix, and the diameter of the pore (7) is substantially 20. Micrometer or more.
