Detailed description of the invention
Below by embodiment, this utility model is specifically described; what be necessary to herein means out is that following examples are only for being further detailed this utility model; can not be interpreted as the restriction to this utility model protection domain, those skilled in the art can make some nonessential improvement and adjustment according to foregoing to this utility model.
Embodiment: a kind of artificial growth tooth system, as Figure 1-4, artificial growth tooth system is made up of root of the tooth prosthese 1, base station 2, screw element 3; Described base station 2 is fixedly connected on described root of the tooth prosthese 1 upper end by described screw element 3; Described root of the tooth prosthese 1 is provided with trapezoidal thread 6 and angular thread 5 from top to bottom; Described trapezoidal thread 6 helical pitch is 0.8mm, and described angular thread 5 helical pitch is 0.6mm; Inner sunken face 4 is provided with between described base station 2 maximum gauge place 7 and described root of the tooth prosthese 1 upper surface 8; Described root of the tooth prosthese 1 top is provided with annular ditch 12.
The shape facility of inner sunken face 4 can promote Bone Ingrowth, and the sclerotin greatly strengthening structure is compatible, has outstanding biocompatibility, structure is merged well with human body bone.Meanwhile, structure is made in use to have higher safety and longer holding time.Meanwhile, after sclerotin, Mucous rehabilitation complete, its adaptation is also improved, and avoids that the connective tissue that causes because of closely sealed deficiency is not closed, the low inferior problem of defense mechanism.
Root of the tooth prosthese 1 is provided with trapezoidal thread 6 and angular thread 5 from top to bottom, solves and should ensure structural strength, the again convenient problem implanted.Through experiment learn, trapezoidal thread 6 helical pitch (S1) is 0.8mm, angular thread 5 helical pitch (S2) for 0.6mm time, the combination property of structure is better.Calculate according to quiet, dynamic loading generally, the helical angle of trapezoidal thread 6 is optimum between 90 ° to 135 °; The helical angle of angular thread 5 is optimum between 30 ° to 80 °; The axial length (L1) of trapezoidal thread 6 is preferably between 4.80mm to 4.90mm; The axial length (L2) of angular thread 5 is preferably between 4.20mm to 4.40mm.
Root of the tooth prosthese 1 surface, with bioactivity coatings, can fast and effeciently start contact surface bone tissue growth, accelerates the wound healing after one-stage operation, to start secondary operation as early as possible, completes Dental Erosion.
The design of annular ditch 12 consolidated further Dental Implant system implant after locating effect, avoid vertically moving or dislocating of structure.The quantity of annular ditch 12 preferably 1-3, the present embodiment is 2.
