摘要： PURPOSE:To improve holding ability and to obtain stable holding by almost parallelly providing two blades, forming a planting part, coupling these blades in the shape of a saddle, for which an upper part is opened, and forming a planting tip edge in one circular arc shape or in a shape where two circular arcs are crossed at least. CONSTITUTION:Two blades 1 with the same dimension are parallelly fixed at an interval A of 2-3mm. The central parts in the upper ends of the blades 1 are coupled by a U-shaped bridge coupling part 4 for fixing and just formed in the shape of the saddle, for which the upper part is opened. Then, nutrition is supplied through an opening window to a bone and the bone is reproduced to swell up. By using a rotary machine tool 5 for which a rotary radius is almost equal with a radius (r) for a circular arc 1b of the blade 1 and thickness is almost equal with thickness (t) of the blade, a bone 6 is notched from the top of an alveolus, whose dental root is opened, and cut to depth at a degree that the blades 1 can be just embedded. Thus, since the two blades 1 are parallelly coupled at the interval A, an artificial dental root is strongly fixed to the bone without fail and planting can be executed with the high holding ability.

摘要： PURPOSE:To prevent the danger of damage when an upper jaw or lower jaw tube is inserted, by molding an artificial dental root by punching the same from a rolled or forged plate material composed of titanium or a titanium alloy by a wire cutting discharge machining method. CONSTITUTION:An artificial dental root is composed of a rolled or forged plate material having a thickness of about 1.2-2.5mm of titanium or a titanium alloy and processed and molded by a method wherein one plate material or a desired number of the plate materials in a laminated and integrated state is punched into a predetermined shape and predetermined dimensions by a wire cutting discharge machining method. Through-holes 3A having a diameter of about 2-4mmphi for strengthening the bonding with the dental root after implantation are formed to the flat part between the corner parts 3a and bottom part 3b of a leg part in an up-and-down direction in a distributed state and the inner wall surface of each through-hole 3A becomes a fine uneven surface by discharge machining to increase in its surface area and the adhesion and bonding with a tooth bone is well performed.

摘要： PURPOSE:To improve the fittingness with a chin bone and strengthen the bonding with the chin bone and improve durability by carrying out the contour shaping work through the electric discharge machining from a metal material and forming an oxidized film on the surface in contact with the chin bone by utilizing the oxidation action in electric discharge. CONSTITUTION:Before and behind shaping-working a head part 10, the outer surfaces of the outer peripheral edges of the blade parts 11 and 12 are shaping-worked, by carrying out electric discharge machining, shifting a wire electrode laid in straight line form in the horizontal direction on the figure along the direction of arrow (a), using pure water as working liquid, and the outside surfaces of the blade parts 11 and 12 are shaping-worked, and the inside surfaces of the blade parts 11 and 12 are shaping-worked along the direction of the dotted arrows (d) and (e), and then the rest inside surfaces of the blade parts 11 and 12 directly under the head part 10 are shaping-worked along the direction of dotted arrow (f), and the edge inner surfaces of the holes 11a, 11b, 12a, and 12b of the blade parts 11 and 12 are shaping-worked along the direction of the dotted arrows (g) and (h). In this case, an oxidized film is formed on the worked surface through the bonding of the metal surface atom which is activated through the electric discharge machining and the oxygen in the pure water in the working liquid.

摘要： PURPOSE:To process a good dental root implanting groove in a jawbone by mounting jig plates on the fixing shaft parallel to the revolving shaft of disc- shaped cutters in the same number as the cutters so as to leave a predetermined distance from the cutters and on the same plane. CONSTITUTION:A jawbone is subjected to cutting processing by rotary cutters 3, 3' to such a degree that depth D enough to just embed the blades 1, 1' of an artificial dental root or depth slightly deeper than that is obtained to simultaneously form two parallel grooves. The bottoms of the grooves are processed into a circular arc shape by the blades 1, 1' and the widths thereof are processed so as to provide a predetermined interval from the blades and the blades 1, 1' are implanted in the grooves to be fixed thereto in a fitted state. The recessed part corresponding to the circular arc of the lower end of a head 2 is simultaneously processed between two grooves by a small diameter cutter 5 and the lower end of the head 2 is also fitted in and fixed to the recessed part. By this method, the artificial dental root can be stably implanted in such a state that implanting holding force is high as a whole.
