EQUIPEMENT CHIRURGICAL D'IMPLANTOLOGIE DENTAIRE ET ELEMENTS, IMPLANT DENTAIRE ET INSTRUMENTS DE FORAGE, CONSTITUTIFS
摘要:
A surgical equipment for implanting dental implants has a boring instrument and an endo-osseous dental implant. The endo-osseous dental implant has a tubular distal section (1) with a cylindrical wall (2) that turns around an axis, is provided with an outer thread (11) and delimits an inner bone material holding volume (3). Its distal end having a thickness 'e' forms a ring-shaped transverse base (4) with an inner diameter 'd' and an outer diameter 'd+2e'. The cylindrical wall has at least one distal indentation (5, 6) that forms a front cutting edge (7, 8) at the ring-shaped base (4). Also disclosed is a boring instrument with a stepped drill having a distal section with a diameter between 'd' and 'd+2e' and a proximal section with a diameter of at least 'd+2e' but smaller than the outer diameter of the thread (11) of the dental implant.
