Dental implant -carrier assembly

A dental implant fixture consisting of an implant with a threaded section (1), an apical end (3) with cutting edges-one of which is straight and which radiates out from the centre—a head (5), a hexagon (4) protruding out of the head, an axial cavity and an open blind threaded cavity (13). The implant has a casing (7) mounted on the hexagon (4) and a shaft (11) with a threaded end (12) that passes through the casing and is fixed into the implant cavity (13). This shaft has a free end, which is operated by a holder (17) with the following features:

• The area connecting the implant head (5) to the threaded section of the implant (1) has a taper of between 48 and 65°,
• The straight cutting edge (6) of the apical end of the implant is inclined in relation to its theoretical radial position at an angle of between 0 and 20°, with the outermost end of the edge the part that first makes contact with the area to be cut,
• The upper head in the standard implant has a diameter of 4.1 mm, and the upper hexagon measures 2.7 mm between faces and is 0.7 mm high, while the threaded section can have a diameter of 3.3, 3.75 and 4 mm.,
• An abutment projecting out of the casing (7) consisting of a hexagonal projection (9) situated on a hexagonal base (8). The sides of both features are in line with each other and with the faces of the implant hexagon
• an O-ring seal (14) made of suitable material and positioned on the projecting end (15, 16) of the fixture shaft (11) and which is housed in the cavity (20) of the holder (17).
