Abstract
The utility model relates to a gap increasing device for first molar root bifurcation. The gap increasing device comprises a handle part, wherein the handle part is provided with a rod part which is provided with a blade end, the work surface of the blade end is provided with a spiked protrusion which extends to the end of the blade end from the joint of the blade end and the rod part, and an included angle of the blade end and the rod part is between 120 degree and160 degree. According to the gap increasing device, the included angle of the blade end and the rod part is between 120 degree and160 degree, the work surface of the blade end can be smoothly inserted at a root bifurcation position below a dental crown due to the curve of the blade end, when in operation, the gap increasing device is placed between a cheek side root bifurcation of the first molar and a cheek side alveolar bone along the longitudinal axis direction of teeth, the handle of the gap increasing device can be struck with a bone hammer in the long axis direction of the teeth, so that the blade end is embedded into the root bifurcation, and then the blade end enters the root bifurcation.
Description
Technical field
This utility model relates to a kind of exodontia instrument, relates in particular to a kind of sixth-year molar furcation area and increases the crack device.
Background technology
Sixth-year molar because of eruption the earliest, be in the middle part of left and right sides jawbone, tooth body anatomic form is complicated, the masticatory function of bearing is maximum, it is high that dental caries and periodontal disease probability occur, and often causes that large of corona destroys or odontoseisis obviously etc. need to be pulled out the trouble tooth.
The sixth-year molar comparatively robust, the number of root many (2-4 roots), furcation area is large, and adjoins etc. (referring to Fig. 1, Fig. 2) with vitals such as maxillary sinus and nervus mandibularis pipes.Have chronic inflammatory disease and granulation tissue to exist if suffer from tooth at apical area, the tip of a root, periodontal membrane and the alveolar bone wall of trouble tooth all has absorption in various degree, odontoseisis, and it is comparatively easy to pull out these teeth.But for the sixth-year molar that has pulpal treatment or rootcanal filling treatment Shi Erxu to pull out, because its dental hard tissue's fragility increases, periodontal membrane space narrows down or disappears, the alveolar bone increase in density, when treatment need be pulled out for many years afterwards, normal the phenomenons such as corona is cracked, root of the tooth is easy to break occuring, obviously increased operating difficulty and become difficult point in the dental extraction, there is no so far desirable method, apparatus solves smoothly.And in extraction, can cause complication in the arts such as root of the tooth Enters upper jaw Dou, interior alveolar nerve injury as dealing with improperly then.
The utility model content
This utility model provides a kind of exodontia that designs for sixth-year molar dissect physiology characteristics specially to increase the crack device with the sixth-year molar furcation area, and this utility model is particularly suitable for the crack that increases of sixth-year molar furcation area.
This utility model adopts following technical scheme:
A kind of sixth-year molar furcation area increases the crack device, comprise: shank, be provided with bar section at shank, be provided with the sword end in bar section, the work surface of described sword end is provided with pointed projection, and pointed projection extends to the end of sword end from the junction of sword end and bar section, and the angle of described sword end and bar section is 120 ° ~ 160 °.
Compared with prior art, the utlity model has following advantage:
(1) to have adopted the angle of sword end and bar section be 120 ° ~ 160 ° technical measures to this utility model, the bending of sword end is so that the work surface of this utility model sword end can successfully be inserted to (Fig. 1 of furcation area place of corona below, the A place of Fig. 2 is furcation area), during operation, follow the tooth y direction, this utility model is placed between sixth-year molar buccal root bifurcated and the cheek side alveolar bone, along the long axis of tooth direction, with the bone hammer gum to knocking pommel of the present utility model, so that the sword end embeds furcation area, the sword end enters furcation area thereupon, in this process, under the combined effect of the technical measures that the spill of the pointed shape of pointed projection 11 and pointed projection and furcation area matches, so that pointed projection has guide effect, under the guiding of pointed projection, the sword end is stably cut between furcation area and the alveolar bone, and the pointed projection on the work surface makes periodontal membrane progressively separate with root of the tooth, to enlarge periodontal spaces, and from the superficial to the deep wedge in the furcation area and alveolar bone gap of sixth-year molar, simultaneously, along with the furcation area of from the superficial to the deep wedging sixth-year molar and alveolar bone gap, the height of pointed projection 11 is along with pointed projection 11 reduces technical measures so that be arranged in furcation area with the height of the pointed projection 11 in alveolar bone gap becomes greatly gradually to the direction of sword end 1 end, thereby so that the tooth generation is stablized and slowly
To displacement, the gap increases.Shake merit about last and increase the crack device to enlarge local tooth socket.Sword end and tissue of tooth contact surface are smooth, make it to be easy to take out.

The specific embodiment
A kind of sixth-year molar furcation area increases the crack device, comprise: shank 3, be provided with bar section 2 at shank 3, be provided with sword end 1 in bar section 2, pointed and the spill furcation area that the work surface of described sword end 1 is provided with pointed projection 11 and pointed projection 11 matches, and pointed projection 11 extends to the end of sword end 1 from sword end 1 and the junction of bar section 2, and described sword end 1 is 120 ° ~ 160 ° with the angle of bar section 2.In the present embodiment, the height of pointed projection 11 is along with the direction of pointed projection 11 to sword end 1 end reduces; The work surface of the surface of pointed projection 11 and sword end 1 is shiny surface.The section of described pointed projection 11 is " crescent ", and shape is for indulging shape protuberance " ridge ", and it is prominent to form point, and after in the dental elevator insertion furcation area district, its protuberance can be well chimeric with furcation area, makes dental elevator be difficult for sliding.This design has also increased the intensity of dental elevator, makes its not frangibility and distortion (see figure 4).
This utility model should be followed in use: whole process is answered clear visual field, avoids alveolar bone wall and nerve, blood vessel injury.Can not firmly knock, can not make the degree of depth that increases the crack excessive, especially should be noted getting when being completely cured except maxillary first molars.With the brisk knocking of bone hammer, increasing the crack can not blindly enlarge, in order to avoid cause unnecessary wound, increase the crack can be progressively with very, pull out and hocket, be used again dental forceps or narrow dental elevator, can be easy to the taking-up of being completely cured.The utlity model has special shape, exquisiteness, directly insert the periodontal spaces in the furcation area district of sixth-year molar when increasing the crack, not only sword is thin in its blade working end, and according to the root furcation anatomy configuration design, its outstanding vertical ridge can form good applying with the spill cambered surface in furcation area district, makes it to be difficult for slippage and damages adjacent teeth and soft tissue thereof.This method can shorten operating time, and wound is less, and is not easy to damage adjacent teeth and periodontal soft tissue.
