Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a jaw plane plate. Background Technology

[0002] In the process of complete denture restoration in clinical orthodontics and prosthodontics departments, accurate measurement of the occlusal plane is a core step in ensuring the success of denture fabrication. The accuracy of the occlusal plane directly affects the occlusal balance after denture fitting, the harmony of the patient's facial morphology, and the restoration of normal eating function. If the occlusal plane is misaligned, it may lead to malocclusion, abnormal facial morphology, and in severe cases, even affect the patient's chewing efficiency and temporomandibular joint health.

[0003] Currently, most traditional occlusal plane plates used in clinical practice are fixed plate structures, whose anterior-posterior position, vertical height, and angle cannot be adjusted. This single structure is difficult to adapt to different patients' dental arch morphology (such as differences in the position of the first and second molars), tooth height, and occlusal plane angle. This leads to the need for repeated tool changes or estimations during the measurement process, which not only reduces measurement efficiency but may also introduce measurement errors due to insufficient adaptability, affecting the prosthetic restoration effect. Utility Model Content

[0004] This invention provides a jaw plane plate to address the problems of the prior art.

[0005] The objective of this utility model can be achieved through the following technical solution: A jaw plane plate includes: a horizontal support, two sets of vertical supports, two sets of measuring plates and a magnetic plate. The magnetic plate is slidably disposed at the lower end of the horizontal support and fixed by screws. The vertical supports are slidably disposed on both sides of the horizontal support and fixed by screws. The measuring plates are rotatably disposed on the inner side of the corresponding vertical supports and fixed by screws.

[0006] In a further improvement, a dovetail groove is provided in the middle of the horizontal support, and a guide rail is slidably arranged in the dovetail groove. The top of the dovetail groove is fixed to the guide rail by a fixing screw, and the magnetic plate is fixedly connected to the lower end of the guide rail by screws.

[0007] In a further improvement, vertical grooves are provided on both sides of the horizontal support, and the lower end of the vertical support is slidably disposed in the vertical groove. A second fixing screw is connected to the outside of the vertical groove, and the second fixing screw passes through the empty groove of the vertical support.

[0008] In a further improvement, a rotating shaft is fixedly connected to the outside of the measuring plate by screws. The rotating shaft is rotatably set in the rotating hole of the vertical bracket. The top of the vertical bracket is provided with a slot that connects to the rotating hole. An angle plate located on the outside of the vertical bracket is fixed on the rotating shaft. A fixing screw three is threadedly connected to the upper end of the vertical bracket. The fixing screw three is located between the rotating shaft and the slot.

[0009] In a further improvement, the measuring plate is a transparent plate with crisscrossing measuring lines distributed on it.

[0011] This invention solves the problem of traditional fixed structures being unable to be adjusted, achieving flexible adjustment in three dimensions: front-back position, vertical height, and angle. The front-back position is adjustable to accommodate the positional needs of different measurement points, such as the first and second molars, satisfying the measurement requirements of the mandibular local or overall occlusal plane. The vertical height is adjustable to precisely match the height of the central incisors in different patients, ensuring a consistent measurement benchmark.

[0016] The following is a description of the embodiments and appendices. Figures 1-2 The technical solution of this utility model will be further described below.

[0017] Example 1

[0018] A jaw plane plate includes: a horizontal support 1, two sets of vertical supports 2, two sets of measuring plates 3 and a magnetic plate 4. The magnetic plate 4 is slidably disposed at the lower end of the horizontal support 1 and fixed by screws. The vertical supports 2 are slidably disposed on both sides of the horizontal support 1 and fixed by screws. The measuring plates 3 are respectively rotatably disposed on the inner side of the corresponding vertical supports 2 and fixed by screws.

[0019] like Figures 1-2 As shown, the practical principle of this utility model is as follows:

[0020] Specific measurement process: Before measurement, loosen fixing screw one, fixing screw two and fixing screw three, align the magnetic plate of the jaw plane plate with the jaw frame and fix it with magnetic attraction to complete the equipment installation.

[0021] After adsorption and fixation, the jaw plane plate can slide freely back and forth along the transverse support because all fixing screws are in a loose state.

[0022] If it is necessary to measure the local occlusal plane formed by the mandibular first molar region and the central incisor, slide the occlusal plane plate forward so that the rear end of the measuring plate fits against the occlusal surface of the mandibular first molar;

[0023] If it is necessary to measure the overall mandibular plane including the second molar, slide the mandibular plane plate backward until the rear end of the measuring plate can cover the mandibular surface area of ​​the second mandibular molar to determine the anterior and posterior position of the fit.

[0024] After confirming the front and rear positions, tighten the first fixing screw to lock the relative position of the horizontal support and the magnetic plate, ensuring that there is no displacement in the front and rear directions during the measurement process.

[0025] Next, adjust the vertical height: gently push the vertical support up and down along the vertical grooves on both sides of the horizontal support, so that the lower end of the measuring plate fits against the occlusal surface of the mandibular central incisor (tooth number 1), ensuring that the measuring reference matches the height of the central incisor. After fitting, tighten the second fixing screw to fix the height of the vertical support. At this point, the vertical position of the measuring plate is locked.

[0026] After fixing the vertical height, rotate the right measuring plate: Hold the outer side of the measuring plate and gently rotate it around the axis until the rear end of the measuring plate is in contact with the occlusal surface of the right mandibular second molar (or the target molar). During the rotation, the angle plate, which is synchronously linked to the axis, will rotate with the measuring plate. The tilt angle of the measuring plate can be read visually through the scale on the angle plate. After the measuring plate is in close contact with the occlusal surfaces of the central incisor and the target molar, tighten the third fixing screw on the right side to lock the angle, completing the measurement of the right occlusal plane angle.

[0027] Repeat the measurement procedure on the right: Loosen the left fixing screw three, rotate the left measuring plate so that its lower end fits against the occlusal surface of the left mandibular central incisor and its rear end fits against the occlusal surface of the left mandibular second molar (or target molar). After reading the angle through the left angle plate, tighten the left fixing screw three to lock the angle, thus completing the measurement of the left occlusal plane angle.

[0028] The magnetic plate is magnetically attached to the jaw frame, providing a stable mounting base for the overall structure and facilitating quick fixing and disassembly. The magnetic plate is connected to the slide groove of the horizontal support via a guide rail, allowing it to slide back and forth along the horizontal support to adjust the front and back position of the measuring plate and adapt to the measurement needs of different teeth (such as the first molar or the second molar).

[0029] The vertical support can slide up and down along the vertical grooves on both sides of the horizontal support to adjust the vertical height of the measuring plate and adapt to the height position of the incisors in different patient models; the measuring plate is connected to the vertical support through a rotating shaft and can rotate around the shaft to adjust the angle and adapt to the tilt angle of the jaw plane of different patients; the angle plate rotates synchronously with the rotating shaft to display the angle value intuitively; fixing screws one, two, and three are used to lock the front and rear position, vertical height, and angle, respectively, to ensure the stability of the structure after adjustment and avoid displacement during measurement.

[0030] This invention solves the problem of traditional fixed structures being unable to be adjusted, achieving flexible adjustment in three dimensions: front-back position, vertical height, and angle. The front-back position is adjustable to accommodate the positional needs of different measurement points, such as the first and second molars, satisfying the measurement requirements of the mandibular local or overall occlusal plane. The vertical height is adjustable to precisely match the height of the central incisors in different patients, ensuring a consistent measurement benchmark. The angle is adjustable and displayed intuitively through an angle plate, accurately adapting to the tilt angle of the occlusal plane in different patients, improving measurement accuracy. The magnetic adsorption design facilitates quick installation onto the articulator, and after adjustment, it is fixed with screws, resulting in a stable structure and convenient operation. This significantly improves the adaptability and accuracy of occlusal plane measurements, providing a reliable basis for complete denture fabrication.

[0031] As a further preferred embodiment, the horizontal support 1 is provided with a dovetail groove 11 in the middle, and a guide rail 12 is slidably arranged in the dovetail groove 11. The top of the dovetail groove 11 is fixed to the guide rail 12 by a fixing screw 51, and the magnetic plate 4 is fixedly connected to the lower end of the guide rail 12 by screws. The dovetail groove is an inverted trapezoidal groove, which forms a sliding pair with the guide rail that matches the shape, allowing the guide rail to slide only in the front-back direction and restricting vertical and horizontal offset; the fixing screw passes through the top of the horizontal support and abuts against the guide rail. When tightened, the guide rail position is locked by friction, which is suitable for position switching when measuring the first molar (needs to be further forward) or the second molar (needs to be further back), ensuring the reliability and repeatability of front-back position adjustment.

[0032] As a further preferred embodiment, the horizontal support 1 has vertical grooves 13 on both sides, and the lower end of the vertical support 2 is slidably disposed in the vertical grooves 13. A fixing screw 52 is connected to the outside of the vertical grooves 13, and the fixing screw 52 passes through the slot 21 of the vertical support 2. The lower end of the vertical support is embedded in the vertical groove of the horizontal support, and the vertical height can be adjusted by sliding up and down along the groove. The slot on the vertical support is an elongated hole, allowing the screw of the fixing screw 2 to pass through and move up and down synchronously with the vertical support. When the fixing screw 2 is tightened, the screw presses against the inner wall of the vertical groove of the vertical support, and the height of the vertical support is fixed by friction. The slot design avoids the fixing screw 2 from obstructing the sliding of the vertical support, and the vertical support is not loose after fixing.

[0033] In a further preferred embodiment, a rotating shaft 6 is fixedly connected to the outer side of the measuring plate 3 by screws. The rotating shaft 6 is rotatably disposed within the rotating hole 22 of the vertical bracket 2. The top of the vertical bracket 2 has a slot 23 communicating with the rotating hole 22. An angle plate 7 located on the outer side of the vertical bracket 2 is fixed to the rotating shaft 6. A fixing screw 53 is threadedly connected to the upper end of the vertical bracket 2. The fixing screw 53 is located between the rotating shaft 6 and the slot 23. The rotating shaft is rigidly connected to the measuring plate and rotates synchronously with the measuring plate. The angle plate is fixed to the end of the rotating shaft, and its scale can intuitively display the rotation angle. The slot at the top of the vertical bracket separates the side wall of the rotating hole into an elastic arm. The fixing screw 53 passes through the elastic arm and abuts against the rotating shaft. When tightened, the elastic arm deforms and squeezes the rotating shaft to achieve angle locking.

[0034] The angle plate makes angle adjustment visible, facilitating precise control of the measuring plate's tilt angle; the slotted elastic design enhances the locking force of the three pairs of rotating shafts of the fixing screw, preventing angle loosening; through the cooperation of the rotating shaft and the elastic arm, the angle adjustment range is wide and the fixation is reliable, which can adapt to the individual differences of different patients' jaw planes and significantly improve the accuracy of angle measurement.

[0035] As a further preferred embodiment, the measuring plate 3 is a transparent plate with crisscrossing measuring lines distributed on it. The transparent material avoids obscuring the tooth model below, making it easy to observe the fit between the measuring plate and the tooth's occlusal surface; the crisscrossing measuring lines form a coordinate grid, which can serve as a reference benchmark to help determine the horizontality and verticality of the occlusal plane.

[0036] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
