Description
Technical field
The present invention relates to a kind of medicine equipment, particularly a kind of many screw thread planting bodies.
Background technology
Oral implantology is the inter-trade medical technology grown up nineteen sixties, makes to be related to doctor
, electronics, machinery, the complex art subject of material and biomethanics；Implant denture is a medical technology interdisciplinary, plantation
Artificial tooth is widely used in the reparation of dentition defect, and tooth-implanting can recover the function of missing tooth to greatest extent, but plantation is adopted
Tooth one has the disadvantage that healing time is long greatly；Lot of experiments shows, certain contact is kept between planting body and bone tissue
The speed of Integrated implant, enhancing primary stability and bone tissue healing can effectively be accelerated；Therefore, expect a kind of in screw-in alveolus
The process and healing stage of bone remain the appearance of the planting body to bone tissue with certain pressure, so as to improve implant denture
Success rate and the probability for realizing i.e. visitor's heavy burden.
The content of the invention
In order to overcome the deficiencies in the prior art, a kind of healing time of present invention offer is short, and primary stability is good, plants successfully
The high many root column planting bodies of rate.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of many screw thread planting bodies, including planting body, the planting body lateral wall are provided with screw thread, and the planting body is in top sides
Edge is provided with chamfering, and the planting body is divided into top, middle part, bottom, and the bottom is provided with self tapping cutting slot；The middle part is inside
Recessed, the screw thread is divided into screw thread, middle screw thread and lower screw thread from top to bottom, and the upper screw thread is the tiny spiral shell of isosceles trapezoid
Line；The middle screw thread is turned under in horizontal crescent；The lower screw thread is not isosceles trapezoid fine thread.
As a preference, the top tangent plane is in isosceles trapezoid.
As a preference, the bottom tangent plane is in circular arc.
As a preference, the top of the planting body inwardly opens up a taper hole, and the taper hole bottom is downward vertically
Stretch a screw.
As a preference, fixed screw thread is provided with the middle part of the screw.
As a preference, overall outline and the horizontal line angle of the upper screw thread are 93 °, and pitch is 0.1mm-
0.2mm。
As a preference, the middle thread pitch is 0.8mm-1.0mm.
As a preference, the lower screw thread and horizontal line angle are 90 °, and pitch is 0.6mm-0.8mm.
As a preference, the self tapping cutting slot opening angle is 120 °, is highly 2mm-5mm.
Present invention has the advantages that：This planting body adds the contact surface with bone tissue by the isosceles trapezoidal structure of upper screw thread
Product, improves the degree of integration of planting body and cortex bone；For enhancing planting body resistance it is vertical to lateral snap-in force, middle screw thread is set
The downward crescent structure of level is counted into, and by increasing the surface area of pitch raising planting body, pitch and middle part planting body volume
Constriction, special structure can increase planting body primary stability；Lower screw thread makes kind using not isosceles trapezoid external thread structure
Implant has three kinds of different screw threads, the lateral pressure different with cancellous bone generation to cortex bone when screwing in jawbone, and middle part
Screw thread has self-locking action, is conducive to planting body primary stability, and the primary stability of high-quality is conducive to Integrated implant.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the plan view of the present invention；
Fig. 2 is the schematic cross-sectional view of the present invention.
Embodiment
In order that the object, technical solution and advantage of the application are more clearly understood, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.
Reference picture 1- Fig. 2, the present invention is a kind of many screw thread planting bodies, including planting body 1, and it is by pure titanium, particularly 5 grade
Titanium material is made, and the lateral wall of planting body 1 is provided with screw thread 2, and the planting body 1 is provided with chamfering, 1 point of planting body in top edge
For top 101, middle part 102, bottom 103, the tangent plane of top 101 is in isosceles trapezoid, is screwed in jawbone, with jawbone tangent plane in angle just
In fixation, the tangent plane of bottom 103 be in circular arc, beneficial to screw in jawbone when stress be uniformly distributed, can be prevented effectively from bone damage
Wound, bottom 103 is provided with self tapping cutting slot 3, and planting body 1 can be made to play self-locking action, increases the primary stability of planting body 1；It is described
Middle part 102 concaves, and can increase the primary stability of planting body 1, visitor can bear a heavy burden, and formed after Integrated implant, the length of planting body 1
More preferably, the screw thread 2 is divided into screw thread 21, middle screw thread 22 and lower screw thread 23, the upper screw thread to phase stability from top to bottom
21 be isosceles trapezoid fine thread, and overall outline and the horizontal line angle of upper screw thread 21 are 93 °, and pitch is 0.1mm-0.2mm,
The screw thread 2 of isosceles trapezoid adds the contact area of screw thread 2 and bone tissue, is conducive to the integration of planting body 1 and cortex bone；It is described
Middle screw thread 22 is turned under in horizontal crescent；The lower screw thread 23 is not isosceles trapezoid fine thread, and pitch is 0.8mm-
1.0mm, pitch increase, the groove of screw thread 2 is deep, can increase the surface area of planting body 1, while the decurved design of horizontal crescent makes
Planting body 1 can resist it is vertical to lateral snap-in force, make fixing-stable；The lower screw thread 23 is the not tiny spiral shell of isosceles trapezoid
Line, is 90 ° with horizontal line angle, pitch is 0.6mm-0.8mm, lower screw thread 23 is extruded to side bone, is conducive to stress
Transmitted inside to bone tissue.
Structure between upper screw thread 21, middle screw thread 22 and lower screw thread 23 is different, makes planting body 1 when screwing in jawbone, to cortex
The bone lateral pressure different with cancellous bone generation, while the decurved structure of horizontal crescent of middle screw thread 22, makes middle screw thread 22
The effect for producing self-locking is locked by jawbone, is conducive to the primary stability of planting body 1, the initial stage of high-quality is conducive to Integrated implant, described
