Abstract
The invention provides an implant. The implant comprises an implant body, a plurality of screw thread areas are arranged on the outer peripheral face of the implant body, and thread tooth thickness of at least one screw thread area in a plurality of screw thread areas gradually increases. In this arrangement, when the implant screws in an alveolar bone, a later screwed thread form squeezes an early screwed thread form path again to achieve a path suitable for the later screwed thread form. The problem that the early screwed thread form path has an impact on the later screwed thread form path is effectively avoided. The stability and reliability of the implant are improved.

With reference to shown in Fig. 1, a kind of embodiments in accordance with the present invention, there is provided planting body.
Specifically, the planting body includes plantation body 10.The outer peripheral face of plantation body 10 is provided with multiple threaded portions, many
The thickness of the tooth form of at least one of individual threaded portion threaded portion gradually increases.
In the present embodiment, the planting body arranges multiple threaded portions using on the outer peripheral face of plantation body, wherein, it is many
The thickness of the tooth form of at least one of individual threaded portion threaded portion gradually increases.So arrange and the planting body is being screwed in
During alveolar bone, the track of the tooth form in front precession is extruded again in the tooth form of rear precession is adapted to rear with reaching
The track of the tooth form of precession, efficiently avoid and cause shadow to the track of the tooth form in rear precession in the track of the tooth form of front precession
Loud problem.Improve the stability and reliability of the planting body.
Wherein, multiple threaded portions include sealing threaded portion 20 and importing threaded portion 30, wherein, tooth form includes arranging
In the importing tooth form 31 for importing threaded portion 30, importing the thickness of tooth form 31 gradually increases.So arranging effectively to pass through
Changing importing tooth form 31 can again be extruded alveolar bone during precession, increased the stable connection of planting body
Property.
As shown in figure 1, plantation body 10 includes construction section 11 and introduction segment 12, sealing threaded portion 20 is arranged at construction section
On 11 outer peripheral face, import threaded portion 30 and be arranged on the outer peripheral face of introduction segment 12, import the thickness of tooth form 31 along towards close
The direction of envelope threaded portion 20 gradually increases.So arrange and continue to install after enabling to introduction segment 12 in precession alveolar bone
Section 11 is screwed in alveolar bone, because the screw thread for sealing threaded portion 20 is fine thread so that play to tooth during precession
The effect of groove bone sealing.
Preferably, the height of construction section 11 is L1, wherein, 4mm≤L1≤6mm.The height of introduction segment 12 is L2, wherein,
6mm≤L2≤12mm.So arrange and cause the planting body that there is more preferable mounting stability.
Specifically, introduction segment 12 includes the first introduction segment 121 and the second introduction segment 122.One end of first introduction segment 121 with
Construction section 11 is connected, and one end of the second introduction segment 122 is connected with the other end of the first introduction segment 121.Second introduction segment 122
The other end be imports end, be provided with cutting edge 1221 on the second introduction segment 122.By cutting of the cutting edge 1221 to alveolar bone
Effect, so arrange enable to will planting body screw-in alveolar bone in it is more laborsaving.
Labour-saving effect is reached in order to further save, by cutting edge 1221 along the axially extending of introduction segment 12.
Refer to again shown in Fig. 1, the internal diameter for importing threaded portion 30 has the along the line of the plantation axis direction of body 10
One taper, the first taper is α 1, wherein, 1≤5 ° of 3 °≤α.So arrange can further improve planting body stability and
Reliability.
Further, the external diameter for sealing threaded portion 20 has the second taper along the line of the plantation axis direction of body 10,
Second taper is α 2, wherein, 2≤12 ° of 8 °≤α.The stability and sealing effectiveness of planting body can so be effectively increased.
In order to further improve dental implants stability and sealing, sealing threaded portion 20 is arranged into triple thread.Its
In, the spacing of each line screw thread of triple thread is h1, wherein, 0.3mm≤h1≤0.4mm.
In order to further reach labour-saving purpose, the helical pitch of each threaded portion is arranged into identical numerical value.And each spiral shell
The helical pitch in line region is h2, wherein, 0.9mm≤h2≤1.2mm.Efficiently reduce implantation moment of torsion.
Specifically, the middle part and bottom of planting body is coarse-pitch thread, after lower bands cone and cutting edge are imported, into middle part
Cylinder, by being processed into 3 ° to 5 ° of slight taper, screw thread addendum width broadens gradually, reaches the mesh of the extruding to alveolar bone
's.Top is taper design, and good sealing effect, triple thread helical pitch is identical with middle and lower part pitch, keeps pitch synchronization, plantation to save
Power and smooth.
Using the planting body in the present embodiment, the planting body is applied to the patient of III, IV osteoid, and planting process is laborsaving,
Primary stability is good after implantation, and patient's healing stage is short, and with the shortest time Dental implantion process is completed, and allows the patient at short notice can be with
Recover masticatory function.
Than that described above, in addition it is also necessary to which explanation is " one embodiment ", " another enforcement spoken of in this manual
Example ", " embodiment " etc., refer to the specific features with reference to the embodiment description, structure or feature and are included in the application summary
Property description at least one embodiment in.It is not necessarily to refer to same reality that in the description statement of the same race occur in multiple places
Apply example.Furthermore, it is understood that when describing specific features, structure or a feature with reference to any embodiment, what is advocated is knot
Close other embodiment also to fall within the scope of the present invention realizing this feature, structure or feature.
In the above-described embodiments, the description to each embodiment all emphasizes particularly on different fields, without the portion described in detail in certain embodiment
Point, may refer to the associated description of other embodiment.
The preferred embodiments of the present invention are the foregoing is only, the present invention is not limited to, for the skill of this area
