Description
Technical field
This utility model is related to a kind of Zhi Kangti, and specifically a kind of mouth cavity orthodontic rectification implant anchorage is followed closely.
Background technology
Orthodontic treatment mainly adjusted by various apparatus for correcting the nerve of facial skeleton, tooth and Maxillary region and muscle it
Between harmony, that is, between the upper mandibular bone of adjustment, between upper lower teeth, between tooth and jawbone and contact their nerve
And abnormal relation between muscle, it finally rescues target is to reach the balance of stomatognathic system, stablize and attractive in appearance.Orthodontic therapy
During, any imposing on treats inevitable one in opposite direction, the size identical power of generation simultaneously of power that tooth moves it, and supports
This mobile situation correcting the counteracting force that tooth body causes is referred to as " anchorage ".In fact, anchorage is to provide to produce orthodontic
The basis of power.Typically in orthodontic treatment, anchorage part is mainly made up of non-tooth of rescuing, and palatine and alveolus also can be used as anchorage
Part.The tooth of anchorage part is that Zhi Kangli is acted on by Orthodontic force produced rightabout power.Anchorage is divided in (1) jaw props up
Anti- (2) intermaxillary anchorage (3) extramaxillary anchorage.Orthodontist often takes much time and energy goes to control anchorage, allows hope to move
Tooth move as much as possible it is undesirable to the tooth of movement moves as few as possible.Anchorage control occupies act in correction is controlled
The status of sufficient weight, only correct anchorage design and good anchorage control, could obtain and high-quality rescue result.
At present, implant anchorage technology is indispensable control anchorage means in mouth cavity orthodontic clinic.Prop up in prior art
Anti- nail is divided into two class formations.The first kind is bolt structure, and it is similar to general bolt structure, has head of screw and the body of screw, spiral shell
Rivet nut is provided with external screw thread, and this anchorage screw screws in and plays fixed traction effect in bone.Such anchorage screw advantage is that fixing force is strong,
Solid and reliable.Its defect is that the thickness to bone has higher requirement, it is desirable to have certain bone amount just can use, therefore to anchorage
Nail position selects there is certain limitation.Equations of The Second Kind is flat sheet-like structure, has referred to as surface implant having.The anchorage of this structure
Can directly be bonded on bone surface, rely on mucosa to cover fixation.But its initial stage fixing force is relatively weak, and needs longer
Healing stage.
Therefore, it is badly in need of a kind of initial stage fixing force at present strong, good stability, can try one's best and not disturbed by bone thickness and root of the tooth,
Simple to operate, and wound less anchorage nail.
Content of the invention
In order to solve the problems of the prior art, the utility model proposes a kind of fixing force is good, do not limited by bone thickness, damaged
Hinder correction implant anchorage body little and easy and simple to handle.
For realizing above-mentioned purpose, this utility model adopts the following technical scheme that：
A kind of correction implant anchorage body, including traction nail and fixed body；Wherein, described traction nail include ailhead, cervical region and
External thread part；Described fixed body includes bone binding face and bone seeks connections with face, and described bone binding face is provided with some implantation nails；Described fixation
Body is gradually thinning to edge by middle part；It is provided with screw slots, described screw slots inwall is provided with and described traction in the middle part of described fixed body
The female thread of nail external thread part coupling, the two is spirally connected.
Wherein more preferably, described implant is pyramidal structure.
Wherein more preferably, described implantation nail number is four to six.
Wherein more preferably, the position of described four to six implantation nails is evenly distributed in bone binding face.
Wherein more preferably, described screw groove sidewall extends the truncated cone-shaped screw slots that fixed body seeks connections with face formation protrusion.
Wherein more preferably, described fixed body is circular, oval, square or rectangle.
Wherein more preferably, described fixed body bone binding face is provided with structure or coating beneficial to Bone Ingrowth.
Wherein more preferably, described Zhi Kangti is made up of pure titanium or titanium alloy material.
The beneficial effects of the utility model are as follows：
1. fixed body bone binding face is provided with some implantation nails, Zhi Kangti can be fixed on bone by tapping, operation letter
Just.The thickness no requirement (NR) to bone for this structure, very thin bone can also be fixed well, and therefore doctor can unrestricted choice anchorage position
Put, and wound is little, other positions will not be injured.
2. the design of implantation nail position increased the fixed effect of Zhi Kangti, prevents Zhi Kangti from rotating.
3. fixed body is gradually thinning to edge by middle part, finds that through experiment this structure can promote week after Zhi Kangti is fixing
Enclose bone length and seek connections with to fixed body bone and bigger fixing force is produced on face, make Zhi Kangti obtain secondary fixation, increased Zhi Kangti's
Steadiness.
