The utility model provides a damaged extender of spenoid, includes handle and work end, the handle is length 8 -12cm's round bar, the work end is fixed in one side of handle, its length are 2 -4cm, the hand ladle of should working draw together with the body of rod that the handle is connected and be fixed in this rod front's working head, the working head is long 4 -6mm, wide 3 -5mm's ligulate, the attenuation gradually before by the late arrival of its thickness, and the rear end thickness of this working head be 5.5 -6.5mm, and front end thickness be 2.5 -3.5mm, and the sagittal of this working head is personally submitted shallow spoonful and is described. The utility model discloses simple structure, preparation are convenient, small in size, convenient operation can avoid squeezeing in the gum end with filling material, prevent that filling material from getting into the gum under, avoided filling material's under the clearance gum extra work, improve work efficiency, practice thrift filling material to reduce to fill a tooth in the treatment to the stimulation of gum.

Description

A kind of wedge shaped defect plugger

Technical field

This utility model relates to medical apparatus and instruments, particularly relates to a kind of wedge shaped defect plugger.

Background technology

At present, the kind of department of stomatology plugger is a lot, but is not also applicable to the special plugger of dental wedge defect at present.

In the filling treatment of wedge shaped defect, traditional plugger size is comparatively large, and operation easier is comparatively large, and under filler easily enters gum, both wasted material, had more again unnecessary material cleaning work, inefficiency, also can cause stimulation to gingiva.

Utility model content

Based on this, for above-mentioned technical problem, provide a kind of wedge shaped defect plugger.

For solving the problems of the technologies described above, this utility model adopts following technical scheme:

A kind of wedge shaped defect plugger, comprise handle and working end, described handle is the round bar of length 8-12cm, the side of described handle is fixed in described working end, its length is 2-4cm, this working end comprises the body of rod be connected with described handle and the working head being fixed on this lever front end, described working head is the tongue shape of long 4-6mm, wide 3-5mm, its thickness is by rear extremely front thinning gradually, the rear end thickness of this working head is 5.5-6.5mm, nose thickness is 2.5-3.5mm, and the sagittal plane of this working head is shallow spoon shape.

Described working end is two, and two working ends are individually fixed in the both sides of described handle, and the front end contrary outwards arc bending of the body of rod of described two working ends, and the working head opposed of these two working ends, described working head and handle are 130-140 ° of angle.

The surface distributed of described handle has network stricture of vagina.

The length of described handle is 10cm, and the length of described working end is 3cm, and described working head and handle are 135 ° of angles, and its length is 5mm, and width is 4mm, and its thickness is by rear to front thinning gradually, and the rear end thickness of this working head is 6mm, and nose thickness is 3mm.

This utility model structure is simple, easy to make, compact, easy to operate, filler can be avoided to clamp-on gum end, under preventing filler from entering gum, avoid the extra work of cleaning gum retrofilling material, increase work efficiency, save filler, and reduce the stimulation to gingiva in filling therapy.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, this utility model is described in detail:

Fig. 1 is structural representation of the present utility model;

Fig. 2 be working head of the present utility model face structural representation;

Fig. 3 is the plan structure schematic diagram of Fig. 2.

Detailed description of the invention

As shown in Figure 1, a kind of wedge shaped defect plugger, comprises handle 110 and working end 120.

Handle 110 is the round bar of length 8-12cm.

Grip for the ease of operator, the surface distributed of handle 110 has network stricture of vagina.

The side of handle 110 is fixed in working end 120, and its length is 2-4cm.

Working end 120 comprises the body of rod 121 be connected with handle 110 and the working head 122 being fixed on this body of rod 121 front end.

As Figure 1-3, working head 122 is the tongue shape of long 4-6mm, wide (rear end width) 3-5mm, after being convenient to first to be close to facing with narrower front end end when filling, move to corona direction, avoid filler being clamp-oned gum end, under preventing filler from entering gum, avoid the extra work of cleaning gum retrofilling material, increase work efficiency, save filler, and reduce the stimulation to gingiva in filling therapy.

The thickness of working head 122 is by rear to front thinning gradually, and the rear end thickness of this working head 122 is 5.5-6.5mm, and nose thickness is 2.5-3.5mm.

The sagittal plane of working head 122 is shallow spoon shape, and shallow spoon shape and tooth lip buccal side form are coincide, and can increase working head 122 and the contact area of defect facing, increase work efficiency.

Particularly, working end 120 is two, two working ends 120 are individually fixed in the both sides of handle 110, the front end contrary outwards arc bending of the body of rod 121 of two working ends 120, and working head 122 opposed of these two working ends 120, working head 122 and handle are 130-140 ° of angle, are applicable to the filling (for ease of the labelling of tooth position, denture is divided into upper right, upper left, lower-left, four, bottom right quadrant by scholar in the past) of four different quadrant inner teeth gears up and down.

Preferably, the length of handle 110 is 10cm, and the length of working end 120 is 3cm, working head 122 and handle are 135 ° of angles, and its length is 5mm, and width is 4mm, its thickness is by rear to front thinning gradually, and the rear end thickness of this working head 122 is 6mm, and nose thickness is 3mm.

Utility model works head 122 more general filling instrument small and exquisite (filling instrument working head length was at about 10mm in the past, thickness is at more than 4mm), be convenient to the filling reparation of rear wedge-shaped erosion of tooth, avoid the stop of and cheek pleural muscle meat too large because of volume and operating difficulties, working head nose thickness 3mm, be thinner than common filling instrument (4mm) and row's of being thicker than gum device (2mm), be convenient to the filling treatment of the wedge shaped defect close to gum edge place, ensured again the intensity of apparatus.

But, those of ordinary skill in the art will be appreciated that, above embodiment is only used to this utility model is described, and be not used as restriction of the present utility model, as long as in spirit of the present utility model, all will drop in Claims scope of the present utility model the change of the above embodiment, modification.
