The work sword that should increase the crack ware is the arc design, adapts to the radian of root of the tooth more, easily inserts between root of the tooth and the alveolus bone, and that conveniently grinds one's teeth in sleep pulls out, this structure, easy operation are applicable to pulling out that complete mouthful tooth was completely cured, and application scope is extensive.

Description

A kind of root of the tooth increases gap device

Technical field

This utility model relates to the increasing gap device used during the exodontia of a kind of department of stomatology, particularly relates to a kind of for dental root fracture of grinding one's teeth in sleep, and General dental elevator cannot go deep into the root of the tooth in root of the tooth and alveolar bone gap and increase gap device.

Background technology

Dental root fracture is the most common a kind of phenomenon in tooth extraction procedure, and especially during molar extraction, incidence rate is higher, its Reason is to grind one's teeth in sleep mostly to be 2～3 roots of the tooth, and root of the tooth is forked, grinds one's teeth in sleep and is positioned at rear section, oral cavity simultaneously, sudden and violent after being once completely cured Reveal out of condition, generally require and open gingival flap and just can see, but for position third molar rearward, even if opening gingiva Lobe can not appear the root of the tooth fractureed very well, increases the difficulty that root of the tooth is pulled out.The most existing apparatus pulling out root of the tooth be mainly dental elevator, Apical elevator and increase gap device, dental elevator with and increasing gap device be typically all straight, limited by bicker, pulled out position grinding one's teeth in sleep rearward Cannot be inserted directly into during root of the tooth；There is certain angle the working end of apical elevator, but the work edge at its tip is suitable only for nearly root The less tabs of point, is not suitable for pulling out bigger being completely cured.Therefore during for grinding one's teeth in sleep, especially third molar is pulled out relevant The apparatus of dental root fracture is the most impracticable.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of root of the tooth to increase gap device, and purpose is in order to solve to grind one's teeth in sleep the especially the 3rd Grinding one's teeth in sleep dental root fracture during pulling out, root of the tooth pulls out this actual techniques problem of difficulty.

In order to solve above-mentioned technical problem, this utility model is accomplished by:

A kind of root of the tooth increases gap device, and including Handheld Division, bar portion and working end, described Handheld Division is provided with bar portion, and bar portion is same several It is arranged to two bent angles in what plane, from Handheld Division to working end, is followed successively by the first bent angle and the second bent angle, described working end and bar Portion is connected, and employing obtuse angle, working end designs, and working end is provided with the work edge using cambered design, and described increasing gap device is for join in pairs Set uses, and the work edge of increasing gap device is in opposite direction in pairs, is used for meeting different parts demand.

Preferably, outer the showing of described Handheld Division is provided with the stria that anti-hands is sliding, and the cross section of Handheld Division is hexagon.

Compared with prior art, this utility model has the advantages that the curved design of work edge of the present utility model, more Adapt to the radian of root of the tooth, it is easy to inserting between root of the tooth and alveolar bone, that conveniently grinds one's teeth in sleep pulls out；This structure, simple to operate, it is suitable for In pulling out that dental pattern is completely cured, applied widely.

Accompanying drawing explanation

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

Fig. 2 is the close-up schematic view in Fig. 1 at A.

Fig. 3 is work edge end cross sectional representation in this utility model.

In figure each labelling be respectively as follows: 1, Handheld Division, 2, bar portion, the 21, first bent angle, the 22, second bent angle, 3, working end, 31, work edge.

Detailed description of the invention

With specific embodiment, detailed description of the invention of the present utility model is described in further detail below in conjunction with the accompanying drawings.

As it is shown in figure 1, a kind of root of the tooth increases gap device, including Handheld Division 1, bar portion 2 and working end 3, described Handheld Division 1 is provided with Bar portion 2, bar portion 2 is arranged to two bent angles on same geometrical plane, is followed successively by the first bent angle 21 He from Handheld Division to working end Second bent angle 22, described working end is connected with bar portion, and employing obtuse angle, working end designs, and working end is provided with and uses cambered design Work edge 31, outer the showing of described Handheld Division is provided with the stria that anti-hands is sliding, and the cross section of Handheld Division is hexagon, described Increasing gap device is for support the use in pairs, and the work edge of increasing gap device is in opposite direction in pairs, is used for meeting different parts demand.

Working end is designed to obtuse angle by this increasing gap device, conveniently stretches into the gap between root of the tooth and alveolar bone；Utilize the arc of work edge Design, has adapted to the radian of root of the tooth, owing to the cross section of Handheld Division is hexagon, plays wheel shaft dynamics, have simultaneously when selection For increasing gap and the effect of dental elevator, increasing gap device and use paired Aided design, the arc of work edge is arranged to rightabout, to meet Different locational requirements.

The above is only embodiment of the present utility model, again states, for those skilled in the art, On the premise of without departing from this utility model principle, it is also possible to this utility model is carried out some improvement, these improve also lists this in In the protection domain that utility model right requires.

Claims (2)

1. a root of the tooth increases gap device, it is characterised in that: include Handheld Division (1), bar portion (2) and working end (3), described Handheld Division Being provided with bar portion, bar portion is arranged to two bent angles on same geometrical plane, is followed successively by the first bent angle from Handheld Division to working end (21) and the second bent angle (22), described working end is connected with bar portion, and employing obtuse angle, working end designs, and working end is provided with Using the work edge (31) of cambered design, described increasing gap device, for support the use in pairs, increases the direction of the work edge of gap device in pairs On the contrary, it is used for meeting different parts demand.

A kind of root of the tooth the most according to claim 1 increases gap device, it is characterised in that: outer the showing of described Handheld Division (1) is provided with The stria that anti-hands is sliding, and the cross section of Handheld Division is hexagon.
