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.
L'invention concerne un équipement chirurgical d'implantologie dentaire com-portant un instrument de forage et un implant dentaire endo-osseux. Selon l'invention, l'implant dentaire endo-osseux comporte un tronçon distal tubulaire (1) comprenant une paroi cylindrique (2) de révolution autour d'un axe présentant un filetage externe (11) et délimitant un volume interne (3) d'emmagasinage de la matière osseuse, et dont l'extrémité distale d'épaisseur "e" forme une base transversale annulaire (4) de diamètre interne "d" et de diamètre externe "d+2e", ladite paroi cylindrique comportant au moins une échancrure distale (5, 6) formant une arête de coupe frontale (7, 8) au droit de la base annulaire (4). De plus, l'instrument de forage comporte un foret étagé présentant un tronçon distal de diamètre compris entre "d" et "d+2e" et un tronçon proximal de diamètre au moins égal à "d+2e" et inférieur au diamètre externe du filetage (11) de l'implant dentaire.
