Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an auxiliary support for dental photography. Background Technology
[0002] In modern oral medicine, digital X-ray imaging technology has become an indispensable diagnostic tool. Intraoral sensors, as the core receiving component of digital X-ray imaging technology, are placed directly inside the patient's mouth. X-rays are emitted through a tube connected to a high-voltage generator, thereby acquiring high-resolution images of teeth and periodontal tissues. This technology provides crucial imaging evidence for dentists to diagnose caries, perform root canal treatment, assess periodontal disease, and plan implant surgeries, greatly improving diagnostic accuracy and treatment success rates.
[0003] However, because the sensor is difficult to locate and fix quickly and accurately in the patient's mouth, it cannot always maintain the best correspondence with the X-ray tube, which directly results in a high failure rate of the first imaging. Therefore, multiple imaging sessions are often required in clinical practice. This not only significantly reduces the efficiency of diagnosis and treatment, but also inevitably increases the cumulative radiation dose received by patients and medical staff, posing a potential health risk. Utility Model Content
[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an auxiliary support for dental imaging, which can quickly and accurately position the sensor at a preset imaging position and maintain stability, thereby ensuring a stable and optimal correspondence between the sensor and the X-ray tube, improving diagnostic efficiency, and reducing the radiation exposure risk for patients and medical staff.
[0005] An oral radiography auxiliary support according to an embodiment of the present invention includes: a support; a focusing ring disposed at the front end of the support, the focusing ring being configured to provide an aiming target point for an external X-ray source; a first limiting groove disposed on the support, the first limiting groove being located at the distal end of the focusing ring, the groove wall of the first limiting groove being parallel to the plane of the focusing ring, the first limiting groove being configured to limit the position of a sensor and make it parallel to the plane of the focusing ring; and a second limiting groove disposed on the support, the second limiting groove being located on one side of the first limiting groove, the second limiting groove being configured to limit the position of the sensor mesh tail.
[0006] It has at least the following beneficial effects: the focusing ring is fixedly mounted on the front end of the bracket, which can serve as a physical reference point, providing a clear visual aiming point for the external X-ray source during imaging, thereby ensuring the accuracy of the projection angle from the source. For example... Figure 2 and 3As shown, a first limiting groove is provided on the support at the distal end of the focusing ring. The plane of the first limiting groove is parallel to the plane of the focusing ring, so as to accurately hold and fix the sensor inside the mouth, ensuring that the imaging plane of the sensor is always parallel to the plane of the focusing ring after placement. A second limiting groove is provided on one side of the first limiting groove on the support. The second limiting groove is used to accommodate and fix the wire mesh tail connected to the rear end of the sensor, preventing the wire from swinging randomly in the oral cavity or getting entangled with tissues such as teeth and cheeks. Thus, the technical solution of this utility model, by combining the focusing ring and the first limiting groove, constructs a standardized projection geometry system, enabling doctors to quickly complete positioning through the focusing ring, ensuring that the sensor and the X-ray tube always maintain the best correspondence, thereby solving the core problems of inaccurate focusing and unstable sensor fixation, improving the success rate of the first imaging, and achieving the effects of improving diagnostic and treatment efficiency and reducing radiation risks for both doctors and patients.
[0007] According to some embodiments of the present invention, it further includes: an upper soft pad disposed at the upper end of the bracket; and a lower soft pad disposed at the lower end of the bracket, wherein the lower soft pad and the upper soft pad are configured to provide stable occlusal support for the teeth.
[0008] According to some embodiments of the present invention, the upper soft pad is provided with a first anti-slip member, and the lower soft pad is provided with a second anti-slip member. The first anti-slip member is configured to prevent displacement between the teeth and the upper soft pad in the biting state, and the second anti-slip member is configured to prevent displacement between the teeth and the lower soft pad in the biting state.
[0009] According to some embodiments of the present invention, the bracket is provided with a first bending portion, which is located between the focusing ring and the first limiting groove. The first bending portion is configured to compensate for the sensor spatial offset caused by the oral cavity structure, so as to ensure that the sensor imaging plane is located at the preset center of the focusing ring and is consistent with the normal direction of the focusing ring.
[0010] According to some embodiments of this utility model, the focus ring and the bracket are detachably connected.
[0011] According to some embodiments of the present invention, a limiting panel is provided on the bracket, the limiting panel is parallel to the plane where the focusing ring is located, and a first limiting groove is formed between the upper soft pad and the limiting panel.
[0012] According to some embodiments of the present invention, the bracket is provided with a second bending portion, which is located between the focusing ring and the first limiting groove, and the second bending portion is configured to avoid the soft tissue of the cheek.
[0013] According to some embodiments of this utility model, the upper soft pad is located in front of the lower soft pad.
[0014] According to some embodiments of the present invention, the cross-sectional area of the upper soft pad gradually decreases from back to front, and the cross-sectional area of the lower soft pad gradually decreases from front to back.
[0015] According to some embodiments of the present invention, the lower soft pad is provided with a third limiting groove, which is connected to the second limiting groove. The third limiting groove is configured to guide and accommodate the sensor circuit.
[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation
[0019] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0020] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.
[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0022] Reference Figures 1 to 7 This utility model discloses an auxiliary support for dental imaging, including a support 1, a focusing ring 2, a first limiting groove 3, and a second limiting groove 4. The focusing ring 2 is disposed at the front end of the support 1 and is configured to provide an aiming target point for an external X-ray source. The first limiting groove 3 is disposed on the support 1 and is located at the distal end of the focusing ring 2. The groove wall of the first limiting groove 3 is parallel to the plane of the focusing ring 2 and is configured to limit the position of a sensor 7 and make it parallel to the plane of the focusing ring 2. The second limiting groove 4 is disposed on the support 1 and is located on one side of the first limiting groove 3. The second limiting groove 4 is configured to limit the position of the tail 71 of the sensor 7.
[0023] Reference Figure 1 The focusing ring 2 is fixedly mounted on the front end of the bracket 1. It serves as a physical reference point, providing a clear visual aiming point for the external X-ray source during imaging, thus ensuring the accuracy of the projection angle from the source. Figure 2 and 3 As shown, a first limiting groove 3 is provided on the bracket 1 at the distal end of the focusing ring 2. The plane of the groove wall of the first limiting groove 3 is parallel to the plane of the focusing ring 2 to precisely hold and fix the intraoral sensor 7, ensuring that the imaging plane of the intraoral sensor 7 is always parallel to the plane of the focusing ring 2 after placement. A second limiting groove 4 is provided on one side of the first limiting groove 3 on the bracket 1. The second limiting groove 4 is used to accommodate and fix the mesh tail 71 connected to the rear end of the sensor 7, preventing the wire 72 from swinging freely in the oral cavity or getting tangled with teeth, cheeks, or other tissues.
[0024] Therefore, the technical solution of this utility model, by combining the focusing ring 2 with the first limiting groove 3, constructs a standardized projection geometry system, enabling doctors to quickly complete positioning through the focusing ring 2, ensuring that the sensor 7 and the X-ray tube always maintain the best correspondence, thereby solving the core problems of inaccurate focusing and unstable sensor 7 fixation, improving the success rate of the first imaging, and achieving the effect of improving the efficiency of diagnosis and treatment and reducing the radiation risk for both doctors and patients.
[0025] In some specific embodiments of this utility model, an upper soft pad 5 and a lower soft pad 6 are also included. The upper soft pad 5 is disposed at the upper end of the bracket 1, and the lower soft pad 6 is disposed at the lower end of the bracket 1. The lower soft pad 6 and the upper soft pad 5 are configured to provide stable occlusal support for the teeth.
[0026] like Figure 1 and Figure 3 As shown, the upper soft pad 5 is fixedly installed on the upper end face of the main body of the bracket 1, while the lower soft pad 6 is fixedly installed on the lower end face of the main body of the bracket 1. The upper soft pad 5 and the lower soft pad 6 are positioned opposite each other, thus forming a stable occlusal support structure. During use, the patient simply needs to bite naturally, allowing the upper and lower teeth to contact and slightly compress the upper soft pad 5 and the lower soft pad 6 respectively. This comfortable biting action quickly and stably fixes the entire bracket 1 in the preset imaging position within the oral cavity. This not only effectively prevents image blurring caused by movement of the bracket 1 during imaging, improving the stability and reliability of the operation, but also increases patient comfort during the examination.
[0027] Furthermore, the upper soft pad 5 and the lower soft pad 6 are made of elastic biocompatible materials. Specifically, flexible materials such as medical silicone, food-grade rubber or thermoplastic elastomers can be selected, which will not be elaborated further here.
[0028] In some specific embodiments of this utility model, the upper soft pad 5 is provided with a first anti-slip member 51, and the lower soft pad 6 is provided with a second anti-slip member 61. The first anti-slip member 51 is configured to prevent the teeth from shifting between the upper soft pad 5 and the teeth in the biting state, and the second anti-slip member 61 is configured to prevent the teeth from shifting between the lower soft pad 6 and the teeth in the biting state.
[0029] like Figures 5 to 7 As shown, to further improve the stability of occlusal fixation, a first anti-slip element 51 and a second anti-slip element 61 are respectively provided on the occlusal surfaces of the upper soft pad 5 and the lower soft pad 6. The first anti-slip element 51 and the second anti-slip element 61 can effectively increase the friction between the teeth and the contact surfaces of the soft pads. Therefore, when the patient bites, it can reliably prevent relative sliding or displacement between the upper and lower teeth and their respective soft pads, thereby ensuring the stability of the entire auxiliary bracket 1 and sensor 7 at the critical exposure moment and eliminating the problem of image blurring caused by slippage.
[0030] Specifically, the first anti-slip element 51 and the second anti-slip element 61 are a series of regularly or irregularly distributed raised structures. In a preferred embodiment, these raised structures are micro-serrated patterns, arrayed hemispherical protrusions, or multiple parallel strip-shaped ridges. Alternatively, the anti-slip element can also be implemented as a high-friction coefficient coating covering the mating surface, such as a food-grade rubber coating or a composite elastomer coating, preventing slippage through the material's inherent viscous properties.
[0031] In some specific embodiments of this utility model, the bracket 1 is provided with a first bending part 11, which is located between the focusing ring 2 and the first limiting groove 3. The first bending part 11 is configured to compensate for the spatial offset of the sensor 7 caused by the oral cavity structure, so as to ensure that the imaging plane of the sensor 7 is located at the preset center of the focusing ring 2 and is consistent with the normal direction of the focusing ring 2.
[0032] like Figure 3 In the specific embodiment shown, the bracket 1 includes a first connecting portion 14, a second connecting portion 15, and a first bending portion 11 connecting the two. The first bending portion 11 is located between the first limiting groove 3 and the focusing ring 2. Specifically, both the first connecting portion 14 and the second connecting portion 15 extend horizontally. The upper soft pad 5, the lower soft pad 6, the first limiting groove 3, and the second limiting groove 4 are all integrated at the rear end of the first connecting portion 14, while the focusing ring 2 is located at the front end of the second connecting portion 15. The front end of the first connecting portion 14 is connected to the rear end of the second connecting portion 15 through the first bending portion 11, and the first bending portion 11 is constructed as an inclined transition structure. Thus, the inclined first bending portion 11 raises the plane where the first connecting portion 14 is located, making it higher than the plane where the second connecting portion 15 is located. This spatial height compensation design can effectively adapt to the anatomical structure of the patient's palate and ultimately ensure that the imaging plane of the sensor 7, which is fixed by the first limiting groove 3, can accurately retract to and align with the preset center and normal direction of the focusing ring 2, thus ensuring the accuracy of the projection geometry.
[0033] In another specific embodiment, such as Figure 7 As shown, the main body of the bracket 1 includes only the first connecting part 14. Similarly, the first connecting part 14 extends horizontally, and the upper soft pad 5, the lower soft pad 6, the first limiting groove 3, and the second limiting groove 4 are all disposed at the rear end of the first connecting part 14. Figure 3 The specific embodiment shown is different. The focus ring 2 is directly connected to the front end of the first connecting part 14 through an inclined first bending part 11, so that the plane where the horizontally extending first connecting part 14 is located is higher than the lowest end of the focus ring 2. This design can simplify the structure and reduce the manufacturing cost while ensuring the basic alignment relationship between the focus ring 2 and the sensor 7.
[0034] In some specific embodiments of this utility model, the focusing ring 2 and the bracket 1 are detachably connected. Specifically, this connection can be achieved through threaded connection, snap-locking, or magnetic attraction, etc., which will not be further elaborated here. It is worth noting that the detachable structure of the focusing ring 2 allows doctors to quickly replace the focusing ring 2 with one of specific specifications according to different imaging needs or sensor 7 models, thereby enhancing the clinical applicability and functional expandability of the equipment. On the other hand, the detachable structure facilitates the separate removal of the focusing ring 2 for thorough cleaning and disinfection after treatment, effectively ensuring medical safety and avoiding the risk of cross-infection. It also provides convenience for the independent replacement of vulnerable parts, thereby effectively extending the overall service life of the product and reducing the storage and maintenance costs of medical institutions.
[0035] In some specific embodiments of this utility model, a limiting panel 12 is provided on the bracket 1, the limiting panel 12 is parallel to the plane where the focusing ring 2 is located, and the first limiting groove 3 is formed between the upper soft pad 5 and the limiting panel 12.
[0036] like Figure 1 , Figure 3 and Figure 7 As shown, a limiting panel 12 is provided on the bracket 1. The limiting panel 12 is parallel to the plane where the focusing ring 2 is located. The first limiting groove 3 is defined by the rear surface of the upper soft pad 5 and the front surface of the limiting panel 12, thus constructing a sensor 7 positioning channel with a precise tilt. When the sensor 7 is inserted into the first limiting groove 3, its rear end face is blocked and calibrated by the front surface of the limiting panel 12, ensuring the parallelism between the imaging plane of the sensor 7 and the plane of the focusing ring 2. At the same time, the front end face of the sensor 7 is constrained by the rear surface of the upper soft pad 5. Since the upper soft pad 5 is an elastic structure, the limiting panel 12 and the upper soft pad 5 together constitute a stable and reliable clamping mechanism. This not only realizes the rapid installation of the sensor 7, but also further ensures the accuracy of the sensor 7's position on the bracket 1, thus providing a core guarantee for obtaining standard X-ray images.
[0037] In some specific embodiments of this utility model, the bracket 1 is provided with a second bending portion 13, which is located between the focusing ring 2 and the first limiting groove 3, and the second bending portion 13 is configured to avoid the soft tissue of the cheek.
[0038] like Figure 1In the embodiment shown for imaging the right posterior molar, the rear end of the second bending portion 13 is connected to the front end of the first connecting portion 14, and its front end is connected to the rear end of the second connecting portion 15. The second bending portion 13, the first connecting portion 14, and the second connecting portion 15 together form a left-protruding relief groove. Through the inwardly concave structure of this relief groove, when the support 1 is placed in the mouth, it provides an effective physical clearance space for the soft tissue on the inner side of the patient's cheek, thereby fundamentally avoiding excessive compression or support of the cheek mucosa by the traditional rigid support 1, significantly improving the patient's comfort and cooperation.
[0039] Furthermore, the first bending portion 11 is integrated on top of the second bending portion 13 and divided into upper and lower functional segments. This structure raises the plane of the upper half connected to the first connecting portion 14 to a higher plane than the plane of the lower half connected to the second connecting portion 15. Thus, the clearance groove is responsible for avoiding the soft tissue of the cheek, while the first bending portion 11 is responsible for compensating for and avoiding the palatal dome structure in the upper part of the oral cavity. The synergistic effect of the two ensures that the support 1 and the sensor 7 it carries can be placed in the ideal projection position in the back of the oral cavity, and coexist harmoniously with all key anatomical structures in the process, providing a reliable spatial guarantee for capturing perfect images in one go.
[0040] It should be noted that in oral X-ray photography, dental films are generally divided into three categories based on the imaging area: anterior dental films, left posterior molar films, and right posterior molar films. For anterior dental films, since the anterior oral cavity has a relatively open space and no large area of soft tissue obstruction, a relatively simplified support structure can be used, such as... Figures 5 to 7 The diagram shows a straight handle configuration without the second bend 13. However, for imaging the left and right posterior molars, since the posterior teeth are located deep within the cheek soft tissue, this invention specifically incorporates a second bend 13. The second bend 13, together with the first connecting portion 14 and the second connecting portion 15, forms an inwardly recessed clearance groove. The groove's protrusion direction has a clear lateral orientation; that is, when imaging the left posterior molars, the clearance groove protrudes to the right to provide clearance space for the left cheek; correspondingly, when imaging the right posterior molars, the clearance groove protrudes to the left to provide clearance space for the right cheek.
[0041] In some specific embodiments of this utility model, the upper soft pad 5 is located in front of the lower soft pad 6. It should be noted that, due to the large curvature of the dental arch and the relatively narrow labial space in the anterior region, placing the upper soft pad 5 in front can effectively reduce the overall thickness of the support 1 on the labial side, thereby making the structure more compact and easier to place in a limited space. At the same time, when the patient bites, the upper and lower anterior teeth can more naturally fall on the front upper soft pad 5 and the normally positioned lower soft pad 6, respectively. This not only conforms to the occlusal mechanics of the anterior teeth and improves comfort, but more importantly, it ensures that the sensor 7 can be close to the lingual side of the anterior teeth at the optimal angle and position, thereby accurately capturing clear images from the incisors to the canines.
[0042] In some specific embodiments of this utility model, the cross-sectional area of the upper soft pad 5 gradually decreases from back to front, and the cross-sectional area of the lower soft pad 6 gradually decreases from front to back.
[0043] like Figures 5 to 7 As shown, the cross-sectional area of the upper pad 5 gradually decreases from back to front, forming a wedge-shaped structure that narrows at the front; while the cross-sectional area of the lower pad 6 gradually decreases from front to back, forming a wedge-shaped structure that narrows at the back. The narrowing shapes of the upper pad 5 at the front and the lower pad 6 at the back perfectly match the physiological curvature of the anterior part of the upper and lower palates, allowing the pads to fit more closely to the palatal dome, thereby achieving better structural stability when the patient bites, and effectively preventing the support 1 from sliding in the front-back direction at the moment of exposure.
[0044] In some specific embodiments of this utility model, the lower soft pad 6 is provided with a third limiting groove 62, which is connected to the second limiting groove 4. The third limiting groove 62 is configured to guide and accommodate the line 72 of the sensor 7.
[0045] like Figure 5 and Figure 6 As shown, the second limiting groove 4 extends vertically and is located at the rear end of the bracket 1, while the third limiting groove 62 extends longitudinally and is located on the lower pad 6. The third limiting groove 62 and the second limiting groove 4 are interconnected, forming a continuous guide channel for the line 72. After the sensor 7 is inserted, the mesh tail 71 extending from the rear end of the sensor 7 is housed in the second limiting groove 4, and the line 72 extending from the mesh tail 71 can be naturally guided and housed in the third limiting groove 62. This neatly organizes the loose line 72 into a preset path, effectively preventing the line 72 from hanging or swinging randomly in the oral cavity or getting tangled with the tongue or teeth. Furthermore, by fixing the line 72, it is prevented from being accidentally pulled during operation, thus avoiding displacement of the sensor 7 and ensuring the stability of the sensor 7's position at the moment of shooting.
[0046] The following reference Figures 1 to 7 The structure shown further illustrates the specific implementation of this dental imaging support.
[0047] Example 1: Reference Figures 5 to 7 This embodiment provides an oral radiography auxiliary bracket specifically for taking anterior dental radiographs. The main body of the bracket 1 adopts a simplified straight handle configuration and does not have a second bending part 13 to adapt to the open space of the anterior tooth area.
[0048] Specifically, the upper soft pad 5 and the lower soft pad 6 are respectively located at the upper and lower ends of the first connecting part 14. The upper soft pad 5 is located in front of the lower soft pad 6. The cross-sectional area of the upper soft pad 5 gradually decreases from back to front to form a wedge-shaped structure, and the cross-sectional area of the lower soft pad 6 gradually decreases from front to back to form a wedge-shaped structure, thereby better conforming to the physiological curvature of the upper and lower palates. When the patient bites, the upper and lower anterior teeth can naturally fall on the corresponding soft pads. Combined with the first anti-slip element 51 and the second anti-slip element 61 on the surface of the soft pad, the bracket 1 can be quickly and stably fixed, ensuring that the sensor 7 is accurately close to the lingual side of the anterior teeth to obtain clear images.
[0049] Example 2: Reference Figures 1 to 3 This embodiment provides an oral radiography auxiliary bracket specifically for taking radiographs of the right posterior molars. To address the issue of the deep space in the posterior tooth area and its proximity to the cheek, the bracket 1 is provided with a second bending portion 13.
[0050] Specifically, the support 1 is provided with a second bent portion 13, the rear end of which is connected to the front end of the first connecting portion 14 of the support 1, and the front end of which is connected to the rear end of the second connecting portion 15 of the support 1. The three together form a left-protruding relief groove, which provides effective physical clearance space for the soft tissue of the patient's right cheek and prevents compression. Furthermore, the first bent portion 11 is integrated on the second bent portion 13, dividing it into upper and lower sections, and the plane of the first connecting portion 14 is higher than the second connecting portion 15, thereby simultaneously avoiding the cheek and adapting to the height of the palatal vault, ensuring that the support 1 can be comfortably and stably placed deep in the left posterior part of the oral cavity to complete accurate imaging.
[0051] Example 3: Reference Figure 4 This embodiment provides an oral radiography auxiliary bracket specifically for taking radiographs of the left posterior molar. Its basic structure and working principle are exactly the same as those of Embodiment 2, and they form a mirror symmetry relationship. Further details will not be provided here.
[0052] The working principle of this dental radiography auxiliary bracket is explained below through specific shooting steps. First, the dentist selects a suitable auxiliary bracket 1 according to the shooting requirements. The intraoral sensor 7 is inserted and secured in the first limiting groove 3, which is formed by the upper soft pad 5 and the limiting panel 12, ensuring that the sensor 7 is reliably fixed and its imaging plane is parallel to the plane of the focusing ring 2. Then, the tail 71 of the sensor 7's circuit 72 is tucked into the second limiting groove 4, and the circuit 72 itself can be naturally embedded in the third limiting groove 62. The bracket 1 with the sensor 7 installed is placed in the target area inside the patient's mouth, and the patient is guided to naturally bite down, so that the upper and lower teeth stably bite onto the upper soft pad 5 and the lower soft pad 6 respectively. The biting force quickly stabilizes the entire bracket 1 in the preset position. For posterior teeth imaging, the second bend 13 and the clearance groove on the bracket 1 actively avoid the soft tissue of the cheek, ensuring comfort and stability. Finally, the dentist directly aligns the X-ray machine's tube outlet with and presses it against the focusing ring 2 at the front end of the bracket 1. Since the plane of the focus ring 2 and the plane of the sensor 7 are forced to remain parallel through the rigid structure of the bracket 1, the sensor 7 is automatically positioned at the center of the projection and on the normal line, achieving the effect of aiming and focusing.
[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0054] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
