Description
Technical field
The present invention relates to medical equipment technical fields, and relate more specifically to a kind of taper padlock planting body implant system.
Background technique
Currently, canine implant, as the main component for realizing Dental implantion technology, structure and function clinically obtains
It is continuous to improve and optimization, canine implant are planted in human body alveolar bone, make up the missing or failure and reality of nature root of the tooth
Its existing masticatory function.Traditional implant neck is the part that stress is concentrated, even if the maximum stress that load generates is far below bone
Strength degree, still can lead to expendable bone fatigue damage, the absorption of implant neck cortical bone causes planting body loose
Dynamic is the major reason for influencing plantation failure.Traditional planting body taper at 4 ° -45 °, the field angle to requirement on machining accuracy not
Height, surface smoothness can reach 0.4um, and base station assembles gap between the latter two and is less than 0.005um, and tradition plantation intracoelomic cavity is basic
All using manufacturing than hexagonal and other polygonal modes, in operative process, implant inner cavity hexagonal structure is installed in base station for this
When, be easy to cause false in place, allows operator to take for base station completely in place, directly applies loading force fastening base station, at this moment
Will cause abutment screw fracture or base station it is stuck plantation intracoelomic cavity, cause new operation risk instead.And the conical surface is shorter
Stress is not easy to disperse；Hexagonal or octagonal connection are not easy in place, padlock effect to be not achieved.
Summary of the invention
Deficiency in view of the above technology, the present invention disclose a kind of taper padlock planting body implant system, can effectively gram
The shortcomings that having taken in the prior art.
The invention adopts the following technical scheme: a kind of taper padlock planting body implant system, comprising: planting body and base station,

Degree is a quarter of the implant diameter, and the gap of the planting body and base station is less than 0.005um.
Further, first screw thread is micro- screw thread, and the distance between screw thread is 0.05mm.
Further, the first bullet implant holes is neck retention grooves, and the length of neck retention grooves is 2mm.
Further, the helical structure is double helix helicitic texture, the spiral between second screw thread away from for
0.6mm。
Further, first screw thread is connect with second thread helix, so that the entirety of the plantation body case
Structure is in helicitic texture.
Further, the root is smooth round blunt shape structure, and the root is provided with third screw thread.
Further, the cutting slot is positive anti-cutting slot, and the cutting slot number is 3, and the cutting slot is set
Be set to blade-like, 3 cutting slots along centrum portion bottom towards the straight stepped arrangement in neck direction.
Further, the implant holes is shaped to the conical by its shape to match with the centrum portion, and the plant
The taper for entering hole is equal to the taper in the centrum portion, and the taper in the centrum portion is within 3 °, and diametrical direction processing error is less than
0.01mm。
Further, first groove of the notch and second groove of the notch are provided on the outside of the installation through-hole.
Further, the first base station cap and the second base station are provided between the installation through-hole and first pyramidal structure
Cap, the first base station cap and the second base station cap are stepped.
Positive beneficial effect:
1, present invention implantation hole length be more than 50 or more length of implant guide stress from around traditional implant neck to kind
The bone tissue transition of implant body portion reduces cervical compressive, anti-bone resorption；
2, straight neck takes micro- Design of Screw Thread in the present invention, and neck cortex bone is not under compression, has between cortex bone and planting body
The good inherent stability and best closure having, excellent retention grooves can be effectively reduced the stimulation to edge cortex bone, subtract
Few bone resorption；
3, vertebra body surface of the present invention is provided with helical structure, and one times can be shortened relative to single thread by being designed using double thread
It performs the operation the time being implanted into, double thread design is to dramatically increase the surface area of planting body, while screw thread can effectively disperse jaw
Power improves the primary stability of planting body, expands bone-plantation body interface area, the self tapping under minimum heat production control.
4, the present invention can bring good initial stage with bone density gradual change using the thread depth expanded step by step, thread depth
Stability；
5, the present invention can arbitrarily adjust plantation angle, realize best repair direction, and when 3 pieces of cutting slots are conducive to plantation
Stability；
6, the butt of planting body of the present invention is designed using round blunt shape, and butt is more smooth, the considerations of in addition to biomethanics it
Outside, once butt approaches or be pierced by cortical bone, nose bottom or Sinus floor, it is possible to reduce the injury to surrounding tissue, to greatest extent
The stress collection at the reduction tip of a root position when neutralizing implantation bone tissue it is impaired；
7, planting body and base station of the present invention gap is less than 0.005um, can enhance the leakproofness of planting body, gap 0.005um
Less than bacterium diameter, bacterial reproduction is prevented.
