[0002] In existing medical procedures, when it is necessary to take X-rays of teeth, patients are often required to hold the film in their mouths with their hands. On the one hand, this method of filming is prone to unclear filming due to finger position problems, or poor filming results due to the movement of the film during the process of being held by the fingers. On the other hand, children or the elderly may have problems with their strength or trembling when holding the film, resulting in offset or blurry films.

[0003] In addition, in the existing technology, in order to avoid the problem of deviation in the filming angle, a spherical filming bracket is used. The filming bracket has a connecting rod, one end of which extends into the oral cavity to reach the tooth end to be filmed, and the other end is connected to a ring. Although this structure makes the centers of the film and the ring in a line to facilitate filming, such equipment is large and complex in structure, and must be connected to the oral cavity when used, resulting in patients having to make some uncomfortable postures in order to cooperate with the position of the spherical bracket.

[0066] This embodiment provides a variety of fixed brackets for dental radiography, which are installed on teeth and used to place films when taking dental radiographs. Figure 1 As shown, it includes a tooth bracket 100 and at least one radiograph bracket 200;

[0067] The tooth support 100 is an arc-shaped structure imitating the gums in the human oral cavity, and can be directly put on the teeth during use.

[0068] The length of the radiographing bracket 200 may be equal to or shorter than the length of the outer wall of the tooth bracket 100 .

[0069] When it is a short structure, the radiographic support 200 is fixedly or detachably mounted on the outer wall of the tooth support 100 .

[0070] During use, after the tooth support 100 is put on the tooth T from bottom to top, the radiographing support 200 is adjusted to the target shooting position, and the film 200 is inserted therein to complete the preparation work.

[0071] In addition, according to the needs of use, the fixing bracket can also be Figure 2This type of short style.

[0072] In addition, the width and size of the fixed bracket are designed to imitate the shape of the human oral cavity. Generally, multiple standard devices can be formulated according to different groups of people (children, adults, the elderly, men, women, etc.), and they can be divided into xxs, xs, s, m, l, xl, xxl, xxl, etc.

[0073] In addition, regarding the specific structure of the tooth bracket 100 and the radiographic bracket 200, Figure 3-9 The specific embodiment of the present invention is described in detail.

[0074] Example 1

[0075] like Figure 3 As shown, Figure 1 Schematic diagram of the cross-sectional structure along AA direction.

[0076] In this embodiment, the tooth bracket 100 is composed of a tooth bracket inner plate 120, a tooth bracket outer plate 110 and a tooth bracket groove bottom plate 130;

[0077] The inner plate 120 of the tooth bracket 100 and the outer plate 110 of the tooth bracket are installed on both sides of the tooth bracket groove bottom plate 130 to form a U-shaped groove I, in which the tooth T is clamped when in use;

[0078] Taking into account the differences in size of human teeth, the device can not only be made into a variety of models, but also be made of deformable materials such as silicone rubber. When put on the outside of the teeth, the tooth bracket can be pressed to make it fit more closely around the teeth, thereby preventing it from falling off during the X-ray process.

[0079] The device can also be made of elastic material, and generally a bracket slightly smaller than the tooth is selected. When it is put outside the tooth, the tooth bracket can fit more closely around the tooth due to its elasticity, thereby preventing it from falling off during the filming process.

[0080] The radiographing bracket 200 is composed of an inner plate 220 of the radiographing bracket, an outer plate 210 of the radiographing bracket and a bottom plate 230 of the radiographing bracket slot;

[0081] The inner plate 220 of the radiographing bracket and the outer plate 210 of the radiographing bracket are installed on both sides of the bottom plate of the radiographing bracket slot to form a U-shaped groove II, in which the film P is clamped when in use;

[0082] The inner plate 120 of the radiograph support and the outer plate 210 of the tooth support are fixed to each other, and the fixing method is one-piece molding, welding, bonding, etc. In addition, in order to make the device as thin and light as possible, thereby reducing the burden on patients, the inner plate 120 of the radiograph support and the outer plate 210 of the tooth support can be two side surfaces of the same plate body, that is, the inner plate 120 of the radiograph support and the outer plate 210 of the tooth support are combined into the shape of the same plate, and the comprehensive thickness is equal to or thinner than the thickness of the inner plate 220 of the radiograph support or the outer plate 110 of the tooth support.

[0083] The groove I and the U-shaped groove II are parallel to each other, so that the film can be parallel to the teeth, thereby fully reflecting the state of the teeth.

[0084] According to the needs of use, the relative height between the groove I and the U-shaped groove II can be adjusted, for example: the groove I is deeper than the groove II, or the groove I is shallower than the groove II, or the groove I is the same height as the groove II.

[0085] Generally speaking, the thickness of each of the above-mentioned plates is between 0.5mm and 7mm;

[0086] The width of the groove I is set according to the width of the teeth of different groups of people;

[0087] The width of the groove II is set according to the thickness of conventional commercially available films and is suitable for different films.

[0088] Example 2

[0089] like Figure 8 As shown, Figure 1 Schematic diagram of the cross-sectional structure along AA direction.

[0090] In this embodiment, the tooth bracket 100 is composed of a tooth bracket inner plate 120, a tooth bracket outer plate 110 and a tooth bracket groove bottom plate 130;

[0091] The inner plate 120 of the tooth bracket 100 and the outer plate 110 of the tooth bracket are installed on both sides of the tooth bracket groove bottom plate 130 to form a U-shaped groove I, in which the tooth T is clamped when in use;

[0092] Taking into account the differences in size of human teeth, the device can not only be made into a variety of models, but also be made of deformable materials such as silicone rubber. When put on the outside of the teeth, the tooth bracket can be pressed to make it fit more closely around the teeth, thereby preventing it from falling off during the X-ray process.

[0093] The device can also be made of elastic material, and generally a bracket slightly smaller than the tooth is selected. When it is put outside the tooth, the tooth bracket can fit more closely around the tooth due to its elasticity, thereby preventing it from falling off during the filming process.

[0094] The radiograph holder 200 is composed of an inner plate 220 of the radiograph holder, an outer plate 210 of the radiograph holder (which is the inner plate 120 of the dental holder and shares a plate body with the inner plate 120 of the dental holder on two sides), and a bottom plate 230 of the radiograph holder groove;

[0095] The inner plate 220 and the outer plate 210 of the radiograph holder are installed on both sides of the bottom plate of the radiograph holder groove to form a U-shaped groove II. During use, the film P is clamped therein;

[0096] The groove I is parallel to the U-shaped groove II, so that the film can be parallel to the teeth, thus comprehensively reflecting the state of the teeth.

[0097] Both sides of the bottom plate 230 of the radiograph holder groove have extension segments 231;

[0098] The extension segments 231 on both sides are in the shape of two arms, and the bottom plate 130 of the dental holder is held therein, but it does not affect the mutual movement between the two structures;

[0099] The extension segment 231 also has a sliding groove 2311;

[0100] Both sides of the bottom plate 130 of the dental holder have sliders 131 with a stop mechanism at positions corresponding to the sliding grooves; the slider with a stop mechanism is composed of a slider with a threaded rod-shaped protrusion fixed on the bottom plate 130 of the dental holder and a nut that can be screwed with the thread;

[0101] During use, the slider with the threaded rod-shaped protrusion passes through the sliding groove, and it can be realized that, when the radiograph holder is pushed or pulled by an external force, the slider moves in the sliding groove to realize the movement in the direction of the arrow, so as to be able to accommodate films P of different thicknesses. That is, when the film is thick, the width of the groove II is increased by pulling, so that the film can be inserted, and when the film is thin, the width of the groove II is reduced by pushing, so that the film can be clamped tightly in the groove;

[0102] When it moves to a suitable position, the bottom plate 130 of the dental holder and the extension segments 231 on both sides thereof are locked and fixed to each other by tightening the nut.

[0103] According to the needs of use, the relative height between the groove I and the U-shaped groove II can be adjusted. For example: the groove I is deeper than the groove II, or the groove I is shallower than the groove II, or the groove I is at the same height as the groove II.

[0104] When the groove I and the groove II are not at the same height as shown in the figure, the structure at the extension segment position remains unchanged, and the structure at the groove part can be adjusted according to the depth requirement.

[0105] Example 3

[0106] like Figure 4 As shown, Figure 1 Schematic diagram of the cross-sectional structure along AA direction.

[0107] In this embodiment, the tooth bracket is composed of a tooth bracket inner plate 120, a tooth bracket outer plate 110 and a tooth bracket groove bottom plate 130;

[0108] The inner plate 120 of the tooth bracket and the outer plate 110 of the tooth bracket are installed on both sides of the bottom plate 130 of the tooth bracket groove to form a U-shaped groove I, in which the tooth T is clamped when in use;

[0109] Taking into account the differences in size of human teeth, the device can not only be made into a variety of models, but also be made of deformable materials such as silicone rubber. When put on the outside of the teeth, the tooth bracket can be pressed to make it fit more closely around the teeth, thereby preventing it from falling off during the X-ray process.

[0110] The device can also be made of elastic material, and generally a bracket slightly smaller than the tooth is selected. When it is put outside the tooth, the tooth bracket can fit more closely around the tooth due to its elasticity, thereby preventing it from falling off during the filming process.

[0111] On the inner side plate of the tooth support, corresponding to one side of the U-shaped groove I, there is an elastic cushion layer 111;

[0112] On the outer side plate of the tooth support, corresponding to one side of the U-shaped groove I, there is an elastic cushion layer 121;

[0113] The elastic cushion layer is generally made of medical silicone rubber material, which is elastic and deformable. When the tooth enters the groove, it can further achieve a clamping effect between the tooth and the bracket.

[0114] The radiographing bracket 200 is composed of an inner plate 220 of the radiographing bracket, an outer plate 210 of the radiographing bracket and a bottom plate 230 of the radiographing bracket slot;

[0115] The inner plate 220 and the outer plate 210 of the radiographing bracket are mounted on both sides of the bottom plate of the radiographing bracket slot to form a U-shaped groove II, in which the film P is clamped when in use;

[0116] The inner side plate of the radiographic support has an elastic cushion layer 221 on one side corresponding to the U-shaped groove II;

[0117] On the outer plate of the radiographic support, one side corresponding to the U-shaped groove II is provided with an elastic cushion layer 211;

[0118] The elastic cushion layer is generally made of medical silicone rubber material, which is elastic and deformable. When the film enters the groove, it can further achieve a clamping effect between the film and the bracket, avoiding the problem of slipping due to saliva secretion in the mouth.

[0119] The inner plate 120 of the radiographing bracket and the outer plate 210 of the tooth bracket are fixed to each other, and the fixing method is one-piece molding, welding, bonding, etc.

[0120] The groove I and the U-shaped groove II are parallel to each other, so that the film can be parallel to the teeth, thereby fully reflecting the state of the teeth.

[0121] According to the needs of use, the relative height between the groove I and the U-shaped groove II can be adjusted, for example: the groove I is deeper than the groove II, or the groove I is shallower than the groove II, or the groove I is the same height as the groove II.

[0122] Example 4

[0123] like Figure 5 As shown, Figure 1 Schematic diagram of the cross-sectional structure along AA direction.

[0124] In this embodiment, the tooth bracket is composed of a tooth bracket inner plate 120, a tooth bracket outer plate 110 and a tooth bracket groove bottom plate 130;

[0125] The inner plate 120 of the tooth bracket and the outer plate 110 of the tooth bracket are installed on both sides of the bottom plate 130 of the tooth bracket groove to form a U-shaped groove I, in which the tooth T is clamped when in use;

[0126] Taking into account the differences in size of human teeth, the device can not only be made into a variety of models, but also be made of deformable materials such as silicone rubber. When put on the outside of the teeth, the tooth bracket can be pressed to make it fit more closely around the teeth, thereby preventing it from falling off during the X-ray process.

[0127] The device can also be made of elastic material, and generally a bracket slightly smaller than the tooth is selected. When it is put outside the tooth, the tooth bracket can fit more closely around the tooth due to its elasticity, thereby preventing it from falling off during the filming process.

[0128] On the inner side plate of the tooth support, corresponding to one side of the U-shaped groove I, there is an elastic cushion layer 111;

[0129] On the outer side plate of the tooth support, corresponding to one side of the U-shaped groove I, there is an elastic cushion layer 121;

[0130] The elastic cushion layer is generally made of medical silicone rubber material, which is elastic and deformable. When the tooth enters the groove, it can further achieve a clamping effect between the tooth and the bracket.

[0138] The inner plate 120 of the radiographing support and the outer plate 210 of the tooth support are detachably mounted to each other. The detachable manner is that the radiographing support can be hung on the inner plate 120 of the tooth support at will through the hanging ear 212.

[0139] The hanging ear 212 is inserted into the gap between the upper end of the elastic pad layer 121 and the outer plate 120 of the tooth support.

[0140] After the hanging is completed, the groove I and the U-shaped groove II are parallel to each other, so that the film can be parallel to the teeth, thereby fully reflecting the state of the teeth.

[0164] After the hanging is completed, the groove I and the U-shaped groove II are parallel to each other, so that the film can be parallel to the teeth, thereby fully reflecting the state of the teeth.

[0165] According to the needs of use, the relative height between the groove I and the U-shaped groove II can be adjusted, for example: the groove I is deeper than the groove II, or the groove I is shallower than the groove II, or the groove I is the same height as the groove II.

[0166] The auxiliary bracket includes a bracket body 310, a handle portion 320 and a fork portion 330;

[0167] The handle portion 320 and the fork portion 330 are respectively fixedly mounted (integrally formed or welded or bonded, etc.) at two ends of the bracket body 310;

[0168] The structure and shape of the fork 330 match the channel 141 on the slot 140. During use, after the tooth bracket is put on the tooth and the film is inserted into the radiographic bracket, the fork of the auxiliary bracket is inserted into the slot 140. The entire bracket can be further firmly fixed in the designated position by holding the handle with the hand.

[0169] Of course, considering that when taking an upper tooth radiograph, if there is no auxiliary bracket, the main bracket may fall off. Therefore, when manufacturing such brackets, brackets corresponding to the upper and lower teeth can also be manufactured separately;

[0170] Then for this type of bracket that is not universal for upper and lower teeth, for the upper teeth bracket, the fork portion 330 of the auxiliary bracket can be directly fixedly mounted on the bottom plate 130 of the tooth bracket groove, so that the slot 140 and its related structures can be omitted.

[0171] Variations of the above embodiment:

[0172] Considering that some teeth are equipped with insert files, in order to ensure that the insert files do not affect the use of the entire bracket, such as Figure 8 As shown, on the bottom plate of the tooth support groove, located at the position of the central axis, a through hole 150 is provided which runs through the entire bottom plate. The diameter of the through hole 150 is generally larger than the outer diameter of a standard file.

[0173] Variations of the above embodiment:

[0174] Considering that human teeth are different, if customization is performed, the cost and treatment time will increase significantly, which is not conducive to the medical process. Therefore, the width of the bottom plate of the tooth bracket groove can be set to an adjustable structure.

[0175] like Fig. 9 As shown, the tooth bracket groove bottom plate is composed of a first movable bottom plate 131, a second movable bottom plate 132 and an adjusting member 10;

[0176] The first movable bottom plate 131 has a pair of slide grooves 1311 on both sides in the length direction;

[0177] The adjusting member is composed of a slider 11, a threaded connecting rod 12 and a nut 13;

[0178] The slider 11 is fixedly connected to one end of the threaded connecting rod 12, wherein the slider portion is disposed above the slide groove 1311, and the connecting rod portion is disposed below the slide groove 1311;

[0179] The other end of the connecting rod 12 passes through the second movable bottom plate 132, and a nut 13 is provided on the end thereof;

[0180] The nut 13 is screwed on the threaded connecting rod 12 and slides up and down by screwing;

[0181] During use, the relative distance between the first movable base plate 131 and the second movable base plate 132 is adjusted by moving the slider in the slide groove. When the relative distance adjustment is completed, the relative position of the first movable base plate 131 and the second movable base plate 132 is fixed by tightening the nut.

[0182] The mutual fixing mentioned in the above embodiments generally refers to conventional fixing means such as integral molding, welding, bonding, screwing, etc.

[0183] The solid state shooting method using the above-mentioned fixed bracket is as follows;

[0184] Step 1, fix the film in the film holder;

[0185] Step 2: Put the tooth bracket with the fixed bracket equipped with the film on the designated tooth; Step 3: Start the machine to take the film.
