Description
Technical field
The invention belongs to field of oral cavity medical equipment, be primarily related to implanting body of artificial tooth.
Background technology
Tooth-planting is the emerging technology that the multi-crossed disciplines such as oral surgery, prosthetic dentistry, science of dental materials and biomechanics, bionics and medical aesthetics produce, and has been acknowledged as frontier most potential in modern Clinical Science of Stomatology development.Its development and maturation significantly improve stomatologic present situation, have promoted stomatologic development.Along with the development of oral implantology, implantation body not only disclosure satisfy that basic masticatory function is recovered, and also wants the aesthetic that can recover even to beautify local, also wants to reach the mechanical property requirements that dummy is supported in structure simultaneously.But implanting body of artificial tooth yet suffers from some problems, as little in born occlusion ability；Implant local occurs that stress is concentrated, and causes frontal resorption；Osseous tissue healing rate is slow, primary stability it is difficult to ensure that.
Summary of the invention
For above mentioned problem, the invention aims to provide a kind of primary stability high, reduce local stress, reduce frontal resorption, shorten healing time, the implanting body of artificial tooth increased the service life.
nullTo achieve these goals，The technical solution adopted in the present invention is: implanting body of artificial tooth，Implantation body top is provided with asymmetric screw thread，Bigger gmatjpdumamics can be born，And screw thread is capable of auto-lock function，Ensure that implantation body will not loosen under the effect without external force，The top of screw thread is that screw thread shoals、The taper shallow thread of tapered design，The damage to cortical bone can be reduced，Accelerate knitting，The top of implantation body is provided with chamfering，Chamfering can increase the contact area with soft tissue，Make that soft tissue form grows is more natural，Implantation body bottom is provided with the cylindricality being slightly less than stress，Implantation body is made to be easier in implant surgery in place，Arc surface is processed in bottom，Arc surface can dispersive stress effectively，Stress collection is avoided to neutralize the root damage to spongy bone，Implantation body is internal to be made up of Morse's taper and cross lock and structure with base station coupling part，Described cross closing component structure is made up of structure sheet，Morse's taper can make connection more firm，Cross closing component structure can be effectively prevented base station and rotate，The sealed lower section of cross is provided with circular hole，The lower section of circular hole is provided with a standard thread blind hole.
Implantation body's profile presents cylindricality, and presents upper taper at footpath, the end, bottom cylindricality, and upper taper angle is 5 °.
Implantation body uses asymmetric screw thread, and pitch is 0.8 mm, and the depth of thread is 0.3 mm, and the angle of screw thread lower limb and horizontal plane is 20 °, top edge be radius be the arc transition of 0.4 mm, top is the cambered surface of 0.1 mm.
Being arc surface and planar profile bottom implantation body, cambered surface radius is 2～5 mm, and planar diameter is 1 mm, and arc surface top, the end is the cylindricality less than end neck, a length of 0.5 mm.
Implant neck is the chamfer design of 0.2 mm.
Being provided with pore structure inside described implantation body, the angle between top vertebral foramen bus and axis is 17 °, deep 0.8mm.
With taper hole be close to for cross closing component structure, the degree of depth 1.8 mm, high 1 mm of cross locking piece.
The sealed bottom of cross is pore structure, hole depth 1 mm, is provided with the fillet that radius is 0.2 mm at the bottom of hole.
Standard thread blind hole it is provided with, deep 2.2 mm of blind hole in hole.
Patent of the present invention is owing to using above technical scheme, it is possible to obtain following technique effect: 1, plantation profile presents cylindricality, and presents upper taper at footpath, the end, bottom cylindricality, column construction can maximally effective dispersive stress, in 5 ° of tapers at neck at the bottom of top, bear bigger stress.2, screw thread is asymmetric screw thread design, it is possible to bear bigger gmatjpdumamics, and screw thread is capable of auto-lock function, it is ensured that under the effect without external force, and implantation body will not loosen.3, threaded upper portion depth shallower, the damage to cortical bone reduces, and the beneficially Integrated implant of implantation body can be effectively prevented the intrusion of microorganism and other pollutant, the beneficially healing rehabilitation in implantation face simultaneously.4,5, neck portion design in an inverted cone, the beneficially release of induced osteogenesis albumen, promote Integrated implant, increase primary stability.6, the design of bottom arc surface, makes stress be easier to around and disperses, it is to avoid bottom stress is concentrated, and lowermost end is plane, makes implantation body more stable.7, it is close to the cylindricality being slightly less than neck at the bottom of implantation body for diameter bottom arc surface, makes implantation body be easier to when implanting in place.8, implantation body and base station coupling part are designed as Morse's taper and add cross closing component structure, make connection more firm, and can be effectively prevented rotation, increase long-time stability, improve implantation body's success rate.

Detailed description of the invention
With embodiment, the present invention is carried out more detailed description below in conjunction with the accompanying drawings.
As it is shown in figure 1, the present invention is the implantation body 1 of a kind of column construction, implantation body 1 top is provided with asymmetric screw thread 2, it is possible to bearing bigger gmatjpdumamics, and screw thread is capable of auto-lock function, it is ensured that under the effect without external force, implantation body will not loosen.The top screw thread of screw thread 2 shoals, tapered design, and taper shallow thread 3 can reduce the damage to cortical bone, accelerates knitting.The top of implantation body 1 is provided with chamfering 4, and chamfering 4 can increase the contact area with soft tissue, and make that soft tissue form grows is more natural.Implantation body 1 bottom is provided with the cylindricality 5 being slightly less than stress, makes implantation body be easier in implant surgery in place.Arc surface 6 is processed in bottom, and arc surface 6 can dispersive stress effectively, it is to avoid stress collection neutralizes the root damage to spongy bone.Being made up of Morse's taper 7 and cross lock and structure 8 as in figure 2 it is shown, internal with base station coupling part, cross closing component structure is made up of structure sheet 9, and Morse's taper 7 can make connection more firm, and cross closing component structure 8 can be effectively prevented base station and rotate.The sealed lower section of cross is provided with circular hole 10, and the lower section of circular hole 10 is provided with a standard thread blind hole 11.
In above-described embodiment, a diameter of 4.1mm of implantation body 1, a length of 12 mm.Screw thread 2 uses asymmetric helicitic texture, as it is shown on figure 3, top edge is arc transition, lower limb tangent line and horizontal angle are 20 °, and screw thread 2 pitch is 0.8 mm, and the depth of thread is 0.3 mm.The angle of upper taper is 5 °, a length of 3mm of conical section；Bottom arc surface 6 radius is 2.5 mm.Angle between Morse's taper 7 bus and vertical curve is 17 °, deep 0.8 mm, and the degree of depth of cross sealed 8 is 1.8 mm.
Being described above a specific embodiment of the present invention, many of which size is to be 4.1 to realize stress
