Embodiment
Shown in Figure 1, be structural representation of the present utility model.Should suitable teaching hospital comprise coniform spiral root shape planting body 3, implant neck 4, neck thread 6, root tip screw thread 7 with artificial tooth implant.Implant neck 4 tops are provided with the cross section and are circle, no base station, threadless taper connection hole 5, and connecting hole 2/3rds is a hex hole at 5 the end, and connecting hole 5 1/3rd is the round taper hole structure outward, and promptly the cross section of planting body topped hole is a circle.See Fig. 2 and shown in Figure 4, described connecting hole structure is beneficial to square body and seals when nail 8 and right cylinder cover screw fixture cover 10 insert fixedly and can not become flexible.The neck thread 6 of described coniform spiral root shape planting body 3 is a triangle thread, and root tip screw thread 7 is an acme thread, and trapezoidal by triangularity to root tip screw thread 7 from neck, thread depth descends gradually.Root tip is provided with 6 anti-spin slots 2, and the tip of a root notch 1 with machinability is established in anti-spin slot 2 belows.Described from the tip of a root to the neck thread gradually by trapezoidal change triangle, the thread depth from coil to coil raises.The easy precession of described helicitic texture can also enlarge pressurization by from coil to coil simultaneously.
Planting method for planting illustrates:
Clinical bone amount is normally named regular plantation, accounts for clinical 60% case, and the bone quantity not sufficient can divide thickness not enough and highly not enough, clinically accounts for 40%, cries complicated the plantation, is to want bone grafting and use biological membrane routinely.
Normal plantation: with upper jaw plantation diameter is that 4mm length is that the planting body of 15mm illustrates.
At first determine plantation point, direction, the degree of depth, make a transparent resin guide plate, in case bore during boring askewly, it is accurate substantially to accomplish to implant point.
Under local anaesthesia, cut the separation of pure property then, direct-view is that the 2mm twist drill is being complied with 1 aperture of guide plate brill with 300 commentaries on classics with diameter down, takes off guide plate, selects an expanding drill, and it is 3mm that size equals planting body tip of a root diameter, and the boring back just can be gone the planting body precession.
Get the coniform spiral root shape planting body 3 among Fig. 1, insert connecting hole 5, twist into flat alveolar bone by per minute 15-30 rotary speed with the hand-operated tools trunk shape precession device among Fig. 39.
Insert at base station connecting hole 5 at last and seal nail 8, advance to bore point at gum and sew up the 1-2 pin, promptly finish kind of a tooth.Crossed a period of time gum healing, after planting body is fixing,, inserted cover screw fixture cover 10 then again dentium sculptura.
Complicated plantation:
Bone quantity not sufficient kind tooth is complicated plantation, when alveolar bone has only 3mm need plant diameter 4mm planting body, as shown in Figure 5, available zigzag scalpel 11 burns on alcohol eliminates blade fragility, beats insertion gently, swing saw dentation scalpel 11 handle of a knifes slowly, go deep into 12mm, as shown in Figure 6, chew shape osteotome 12 with duck again and cut a hole, enlarge implantation hole, through planting depth gets final product.Than directly good with osteotome, the one, vibrate little, the 2nd, fracture line is in both sides, and is less to the plantation influence.
If phatnoma bone height is lower than 8mm, when having only 5mm need plant the planting body of 8mm length, the too short planting body of 5mm can adopt to push away the plantation of bone method at present also in arguement.As shown in Figure 7, on alveolar bone, bore a tubular bone with core drill 13 earlier, do not take out, also do not bore.As shown in Figure 8, with the rotating head 15 of planting body hand-operated tools 14 front ends of a size tubular bone is slowly released.Put into planting body again, a kind of may the far-end fracture being pushed out, another kind may not fractured, and the centre is pushed out a cavity, is which kind of fracture all is counted as merit.This method is directly advanced than promoting in the ballistic method, does not need bone grafting and biological membrane, and the head power that is hit is few, easily controls.
