Abstract
A kind of minimally invasive crown slitter of dentistry, includes the clamp structure of pushing arm and confrontation arm composition, breaks rotation and the resetting structure of hat sword and its rotating shaft composition, the crank handle structure with radian.The abjection power of broken hat sword is limited in the complete grasping system of working end all the time, and abjection power is consistently equal to resistance, and horizontal resultant is approximately zero.Handle of holding with a firm grip make in pairs broken hat sword open, when broken hat sword struts dummy, for the trend of broken hat sword abjection, structural system itself can provide resistance, thus avoid it is artificial apply lateral thrust, damage periodontium.
Description
Technical field
The utility model belongs to oral medical apparatus technical field, is concretely a kind of the broken of slight side force of application
It is preced with device.
Background technology
Ill fitting prosthesis is the common disease and frequently-occurring disease of the department of stomatology, one clinically mainly made at present using metal
Word screwdriver-shaped crown slitter carries out broken hat with jaw type crown slitter.Usual way is longitudinally to grind a depth in dummy buccal aspect
Up to the ditch of adhesive layer, the operation principle of traditional crown slitter is that work edge is stretched into groove, and rotation is prized.Due to groove during force
Inner wall smooth and section is curved, work edge easily slides out.
In order to resist the trend skidded off, generally require force and withstand abutment to be prized, can produce during this larger
Lateral thrust, so as to cause immeasurable damage to the periodontium of abutment, thus traditional broken hat mode in abutment again
Healthy hidden danger has just been buried before treatment.Reducing lateral thrust helps to protect periodontium, and raising is suffered from after tooth treats again
Late result, it is therefore desirable to having a kind of can reduce the crown slitter tool of lateral thrust.
The content of the invention
The main purpose of the design is even to prevent the repressive damage that apparatus is caused to periodontium during broken hat to reduce
Wound.The primary structure of the present apparatus includes：Pushing arm 1, height 10mm.Resist arm 2, height 12mm.Broken hat sword 3, long 8mm is thick
4mm, the widest part 2mm.Broken hat sword rotating shaft 4, adaptation spring make it that two-edged inward turning resets and offseted under quiescent condition.Anti-skidding silicagel pad
5, increase non-skid property with concave convex texture.Girder 6 is connected, there is provided structural framework for connection each several part.Handle 7,8 passes through hinge 9
It is connected, and there should be certain radian even adjustable-angle to be limited to adapt to intraoral space as shown in Figure 3.The design structure
Practicality reasonable in design, is easy to the operation of narrow space in oral cavity, and side force is to abutment periodontal tissue during can reducing brokenly hat
The damage caused, has filled up the blank in minimally invasive broken hat field to a certain extent, to treating again and periodontosis prognosis for abutment
With certain facilitation, the comfort level that abutment is treated again is improved, the risk of periodontal tissue destruction is reduced, so as to improve complete
Civilian's chamber general level of the health.
It should be noted last that, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted.Although ginseng
The present invention is described in detail according to embodiment, it will be understood by those within the art that, to the technology of the present invention
Scheme is modified or equivalent, and without departure from the spirit and scope of technical solution of the present invention, it all should cover at this
Among the right of invention.
Brief description of the drawings

Fig. 3：Full structure top view
1. pushing arms in accompanying drawing 1,2,2. confrontation arms, 3. broken hat swords, 4. broken hat sword rotating shafts, 5. anti-skidding silicagel pads, 6. connections
Girder, 7. body-handles, 8. flexible handles, 9. hinges, 10. corona dummies.
Embodiment
On the hat dummy 10 that minimally invasive crown slitter working end is held on to milled cheek lateral sulcus, broken hat sword 3 stretches into cheek side in pairs
In ditch.Pass through handle 7,8 of holding with a firm grip so that pushing arm 1 is moved forward, pushing arm 1 and the confrontation formation clamping trend of arm 2.Pushing arm
Be forced into broken hat sword 3 so that broken hat sword struts hat dummy 10, now because clamping between pushing arm 1 and confrontation arm 2
Trend, it is therefore prevented that the abjection of broken hat sword, abjection power is bigger, and chucking power also accordingly increases, and whole system keeps dynamic equilibrium, no longer
Need operator to prop up hat dummy 10 to prevent brokenly hat sword abjection.
Power needed for strutting dummy is bigger, and abjection power is bigger, but the resistance of clamping is corresponding also bigger, horizontal direction
Make a concerted effort to be zero.The more traditional crown slitter of the present apparatus, can be greatly reduced the side force to abutment, and the bone tissue of effectively protection periodontal is good for
Health, is conducive to the therapeutic effect in long term.
Claims (3)
1. a kind of minimally invasive crown slitter of dentistry, includes the clamp structure of pushing arm and confrontation arm composition, hat sword and its rotating shaft composition are broken
Rotation and resetting structure, the crank handle structure with radian.
2. a kind of minimally invasive crown slitter of dentistry according to claim 1, the abjection power of broken hat sword is limited to working end all the time
