Description

Intraoral occlusal fin occlusion fixing projection support

Technical Field

The utility model relates to an oral care field specifically relates to a fixed projection support of intraoral occlusal flap interlock that is used for shooting the dental crown of upper and lower jaw tooth and the occlusal condition of upper and lower tooth.

Background

The intraoral occlusal flaps are used for shooting the crowns of the upper and lower teeth and the occlusion conditions of the upper and lower teeth. The special photography for the tooth crown part can lead the crowns of the upper and lower teeth to be included on the same photograph, but the root tip part of the teeth cannot be included. The dental crown part is often examined for caries, relationship between occlusal and adjacent surfaces of teeth, caries and pathological changes in the pulp cavity.

The shooting method is that the IP image die piece is provided with a disposable plastic sleeve, and a protruding paper board is arranged in the middle for occlusion during shooting. The patient sits on the examination chair, the sagittal plane of the head is vertical to the ground, and the maxillary occlusal plane is parallel to the ground. When in projection, the IP image plate is placed in the mouth of a patient, then the patient is ordered to slowly bite the middle protruding paper plate, and the film is close to the teeth. The X-ray angle is 8 degrees at the vertical angle, and the X-ray horizontal angle is parallel to the adjacent surface of the irradiated tooth. However, when an IP image plate is placed in a conventional shooting method, the patient needs to have high matching degree, and the vertical angle and the horizontal angle of the projection X-ray are required to be shot accurately, but often the patient can have large pharyngeal reflection when the IP image plate is placed in the patient, so that the problems of position slippage, displacement and the like easily occur in the oral cavity of the patient, the quality of the shot image is reduced, repeated shooting is required, and the radiation dose is increased for the patient.

Disclosure of Invention

The purpose of the invention is as follows: the utility model aims to provide a not enough to prior art, patient's pharynx reflection is little when being used for shooting intraoral occlusal flap, and the interlock is easy, is difficult to take place the fixed support of throwing photograph of intraoral occlusal flap interlock of position slippage, aversion in patient's oral cavity.

The technical scheme is as follows: the utility model discloses an intraoral occlusal fin occlusion fixation projection bracket, which comprises a bracket main body, two clamping pieces positioned at two ends of the bracket main body and an occlusion piece fixed at one side of the bracket main body;

the two clamping pieces are arranged oppositely, clamp the image plate and fix the image plate on the other side of the bracket main body far away from the occlusion piece;

the occlusion piece is attached to the support main body, and convex or concave grains are arranged on the surface of the occlusion piece.

The utility model discloses further preferred technical scheme does, the holder is the splint of L shape, and the both ends at the support main part are fixed respectively to a side of two splint, opposite side board with the support main part is parallel.

Preferably, the distance between the side plate of the clamping piece parallel to the bracket main body and the main frame main body is matched with the thickness of the image plate.

Preferably, the engaging member is made of soft silicone rubber, and has a width corresponding to the width of the stent body and a length slightly shorter than the length of the stent body.

Preferably, one end of the bracket main body is also provided with a hand piece, and the hand piece is parallel to the bracket main body.

Preferably, the stent body is made of a radiolucent plastic material

Has the advantages that: (1) the utility model discloses an occluding piece is laminated on the support main part, and its surface is provided with protruding or sunken line, can increase the occlusal force, prevents the position slippage and skew, and patient's pharynx reflection is little, and the interlock is easy, adopts the fixed projection support centre gripping intraoral occlusal fin of the utility model, can avoid repeated irradiation many times to increase the problem of patient's radiation dose; the clamping pieces are arranged oppositely to clamp the image plate, so that the angle of the image plate can be fixed, and the accurate incidence of the vertical angle and the horizontal angle of the projection X-ray is ensured;

(2) one end of the bracket main body of the utility model is also provided with a hand-held piece, which is convenient for holding, and avoids the operating hand of the doctor from touching the oral cavity of the patient and causing cross infection; meanwhile, the handheld piece is parallel to the support main body, so that the doctor can operate conveniently, and the doctor can adjust the angle of the image plate through the handheld piece.

1-bracket body, 2-clamping piece, 3-occluding piece and 4-hand piece.

Detailed Description

The technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the embodiments.

Example (b): the utility model provides a fixed support of throwing of occlusal fin interlock in mouth, includes a support main part 1, is located two holders 2 at 1 both ends of support main part, is fixed in occlusal piece 3 of 1 one side of support main part to and the handheld piece 4 of the one end of fixed support main part 1.

The stent body 1 is made of a plastic material which is transparent to X-rays, and the hand piece 4 is parallel to the stent body 1.

The occluding piece 3 is made of soft silica gel, the width of the occluding piece is consistent with that of the bracket main body 1, the length of the occluding piece is slightly shorter than that of the bracket main body 1, the occluding piece 3 is attached to the bracket main body 1, and convex or concave grains are arranged on the surface of the occluding piece.

Two holders 2 set up in opposite directions, and holder 2 is the splint of L shape, and a side of two splint is fixed respectively at the both ends of support main part 1, and another curb plate is parallel with support main part 1. The distance between the side plate of the clamping piece 2 parallel to the bracket main body 1 and the main frame main body is matched with the thickness of the image plate. The image plate is clamped and fixed on the other side of the bracket body 1 far away from the occlusion piece 3.

When in use, the IP image plate is firstly arranged in the disposable plastic film sleeve, and the prepared IP image plate is clamped between the two clamping pieces 2, so that the bracket main body 1 is ensured to be positioned at the middle position of the IP image plate.

Order the patient to open the mouth, order the patient to slowly bite the soft silicone occlusion piece 3, and make the IP image plate and the teeth close to each other as much as possible.

As mentioned above, although the present invention has been shown and described with reference to certain preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
