Description

Technical Field

[0001] This utility model relates to the field of dental restoration equipment technology, specifically to a digital Gothic bow device. Background Technology

[0002] Accurate recording and transfer of jaw position relationships is a crucial step for edentulous patients undergoing full-mouth restoration. To better address the challenges faced by patients with small dental arches and steep alveolar ridges in recording and transferring jaw position relationships, various digital Gothic arch devices have been designed to achieve personalized recording and transfer of jaw position relationships.

[0003] Existing digital Gothic bow devices have the following drawbacks:

[0004] Firstly, when recording and transferring jaw position relationships, if the jaw plane is tilted anteriorly or laterally, it can easily increase the horizontal force on the denture, causing it to shift. However, current digital Gothic arch devices cannot adjust the jaw plane within the patient's mouth; they are usually set according to the designer's experience to evenly divide the occlusal space, which does not conform to the patient's actual occlusion. An incorrect jaw plane will lead to inaccurate jaw position relationships, which in turn will affect the tooth arrangement of complete dentures, the establishment of balanced jaws, and the final functional recovery.

[0005] Secondly, the digital Gothic arch devices currently available all use open impressions, which cannot achieve edge shaping when the patient is in the correct occlusal position, thus failing to obtain a more accurate working model and affecting the adhesion of the denture. Utility Model Content

[0006] The technical problem to be solved by this invention is to accurately obtain the jaw position relationship in existing digital Gothic bow devices. The purpose is to provide a digital Gothic bow device to solve the above-mentioned problem.

[0007] This utility model is achieved through the following technical solution:

[0008] A digital Gothic bow device includes a maxillary bow adapted to the patient's maxilla and a mandibular bow adapted to the patient's mandible, wherein the maxillary and mandibular bows are detachably provided with occlusal plates for obtaining a closed-mouth impression or tracing elements for obtaining a centric jaw relationship.

[0009] In one possible design, when the digital Gothic bow device is used to obtain a closed impression, occlusal plates are provided on both the maxillary and mandibular arches.

[0010] The recording device includes a lower recording device and an upper recording device. When the digital Gothic bow device is used to obtain the centric jaw relationship, the mandibular bow is provided with a lower recording device for obtaining the mandibular movement trajectory, and the maxillary bow is provided with an upper recording device for recording the mandibular movement trajectory and obtaining the trajectory apex.

[0011] In one possible design, both the maxillary and mandibular arches include trays and adjustment modules;

[0012] The tray has opposing occlusal and working surfaces. The occlusal surface is adapted to the patient's maxilla or mandible, and the working surface is connected to other components via an adjustment module.

[0013] There are 3-5 adjustment modules spaced apart on the working surface of the tray. Each adjustment module is movably connected to the tray and used to adjust the position of other components.

[0014] In one possible design, the tray is equipped with a sliding column and a fixing rod located at the connection between the tray and the adjustment module;

[0015] The sliding column extends outward and is provided with a sliding groove adapted to the adjustment module. Correspondingly, the adjustment module is slidably mounted on the sliding column.

[0016] The sliding column is provided with a fixing hole that communicates with the sliding groove, and the fixing rod is detachably installed on the fixing hole and used to fix the adjustment module.

[0017] In one possible design, the adjustment module includes a base column and a sliding block. The base column is slidably mounted on a slide column of the tray. The outward-facing end of the base column has a concave ball groove for connecting other components. Accordingly, the base column is connected to other components via a ball joint connection. The sliding block is disposed on the side of the base column and is at least partially exposed outside the slide column.

[0018] In one possible design, the mandibular arch also includes an arch plate, the bottom surface of which is connected to a tray via an adjustment module, and the top surface of which is detachably connected to an occlusal plate or a mandibular prosthesis.

[0019] In one possible design, the bite plate is constructed in an arch shape to fit the arch plate, with a minimum thickness of 0.5 mm and increasing in increments of 0.5 mm to form a thickness step.

[0020] In one possible design, the lower tracing component includes a tracing plate and a tracing screw. The two ends of the tracing plate are used to connect to the bow plate, and the middle of the tracing plate is provided with a tracing hole adapted to the tracing screw. The tracing screw is detachably mounted on the tracing hole. Accordingly, the length of the tracing screw extending out of the tracing plate is equal to the thickness of the selected engagement piece. The tracing hole is constructed as a screw hole.

[0021] In one possible design, the upper recording component includes a recording plate and a card plate. The top surface of the recording plate is connected to a tray via an adjustment module, and the bottom surface of the recording plate is detachably connected to the card plate. The card plate is provided with an adjustment groove for adjusting the position of the card plate relative to the recording plate and a recording hole for recording the position of the recording screw. Correspondingly, a fixing screw for connecting the recording plate and the card plate passes through the adjustment groove, and the recording hole is adapted to the recording screw.

[0022] In one possible design, the outer end of the stencil has an outwardly extending face bow connection structure.

[0023] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0024] By adjusting at least one of the maxillary and mandibular arches—that is, adjusting it intraorally according to the clinical situation—a correct occlusal plane is obtained. Using this occlusal plane as a reference, on the one hand, occlusal lenses are used to obtain a closed-mouth impression of the patient through closed occlusion. In this position, the patient's closed occlusion is in the correct occlusal relationship, with the upper and lower occlusal lenses in close contact, resulting in a more accurate closed-mouth impression and more precise shaping of the occlusal margins. On the other hand, tracing elements are used to accurately obtain the patient's centric occlusal relationship, resolving the problem of dividing the occlusal space based on personal experience, and making the occlusal relationship more consistent with the patient's actual occlusion.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model. Example

[0036] like Figures 1-7 As shown, a digital Gothic bow device includes a maxillary bow 100 adapted to the patient's maxilla and a mandibular bow 200 adapted to the patient's mandible. The maxillary bow 100 and the mandibular bow 200 are detachably provided with an occlusal piece 300 for obtaining a closed-mouth impression or a tracing piece for obtaining a centric jaw relationship.

[0037] When the digital Gothic bow device is in operation, although the maxillary bow 100 and mandibular bow 200 are located in the patient's maxilla and mandible respectively, the maxillary bow 100 and mandibular bow 200 are constructed with basically the same components to reduce costs and improve economy.

[0038] Regarding the acquisition of different types of data, namely obtaining a closed-mouth impression using occlusal film 300 and obtaining centric jaw relationship using tracing pieces, specifically:

[0039] When a patient tries on the digital Gothic bow device, both the maxillary arch 100 and the mandibular arch 200 are located in the patient's mouth, with the maxillary arch 100 and mandibular arch 200 positioned in the patient's maxilla and mandible, respectively. After adjusting at least one of the maxillary arch 100 and mandibular arch 200, i.e., adjusting within the patient's mouth according to clinical needs, the correct jaw plane is obtained.

[0040] Using the occlusal plane as a reference, the device works in conjunction with the occlusal lens 300 to obtain a closed-mouth impression of the patient through closed occlusion. In this position, the patient's closed occlusion is in the correct occlusal relationship, with the upper and lower occlusal lenses 300 in close contact, resulting in a more accurate closed-mouth impression and more precise shaping of the occlusal margins. Simultaneously, it works with the tracing element to accurately obtain the patient's centric jaw relationship, resolving the issue of dividing the occlusal space based on personal experience and ensuring that the jaw relationship more closely matches the patient's actual occlusion.

[0041] In one possible implementation, both the maxillary arch 100 and the mandibular arch 200 include a tray 1 and an adjustment module 2;

[0042] The tray 1 has opposing occlusal surfaces and working surfaces. The occlusal surfaces are adapted to the patient's maxilla or mandible, and the working surfaces are connected to other components via the adjustment module 2.

[0043] The adjustment module 2 has 3-5 units and is spaced apart on the working surface of the tray 1. Each adjustment module 2 is movably connected to the tray 1 and is used to adjust the position of other components.

[0044] Based on the above design scheme, tray 1 is designed according to the obtained patient initial impression. When the patient tries on the digital Gothic bow device, the occlusal surface of tray 1 fits the patient's maxilla and mandible to minimize errors. The working surface of tray 1 is connected to adjustment module 2. By adjusting the relative position of module 2 with respect to other components, an accurate occlusal plane is obtained.

[0045] As is easily understood, the tray 1 is constructed to fit any shape of the upper or lower jaw. Due to the differences between different patients, the specific shape of the tray 1 varies from person to person in order to achieve the purpose of personalized customization and improve the accuracy of relevant data acquisition. Therefore, this embodiment does not impose any restrictions on the shape of the tray 1.

[0046] The mandibular arch 200 includes an arch plate 3 and an adjustment module 2 for adjusting the position of the arch plate 3 so that the arch plate 3 is horizontally aligned with the patient's nasal ala-tragus line, i.e., parallel to the patient's correct jaw plane. At this point, the position of the arch plate 3 can be fixed to obtain the correct jaw plane, thereby establishing a benchmark for subsequent data acquisition, which helps to reduce errors and improve the accuracy of the data.

[0047] It is worth noting that, considering the shape of the maxilla and mandible, the adjustment module 2 has at least three parts, with two located at the molars on both sides and the other at the incisors. If necessary, the number of adjustment modules 2 can be increased to five to avoid both an excessive number of adjustment modules 2 and interference between them, which could lead to insufficient adjustment range.

[0048] For other components, in this embodiment, it refers to one of the occlusal plate 300, the arch plate 3, and the upper component 420. It is readily understood that if the digital Gothic arch device is used to acquire other oral data, any suitable existing components can be selected.

[0049] In one possible implementation, the tray 1 is provided with a sliding column 101 and a fixing rod 102 located at the connection between the tray 1 and the adjustment module 2;

[0050] The sliding column 101 extends outward and is provided with a sliding groove adapted to the adjustment module 2. Correspondingly, the adjustment module 2 is slidably disposed on the sliding column 101.

[0051] The sliding column 101 is provided with a fixing hole that communicates with the sliding groove, and the fixing rod 102 is detachably mounted on the fixing hole and used to fix the adjustment module 2.

[0052] Based on the above design, the adjustment module 2 is slidably mounted on the slide column 101 so that the adjustment module 2 can slide up and down relative to the slide column 101, thereby adjusting the relative height between adjacent adjustment modules 2. When the adjustment module 2 slides to the required position, the position of the adjustment module 2 can be pressed and fixed by the fixing rod 102 to obtain an accurate jaw plane and avoid disturbance in subsequent work.

[0053] In one possible implementation, the adjustment module 2 includes a base column 201 and a sliding block 202. The base column 201 is slidably disposed on the slide column 101 of the tray 1. The outward-facing end of the base column 201 is provided with a concave ball groove for connecting other components. Accordingly, the base column 201 is connected to other components through a ball joint connection. The sliding block 202 is disposed on the side of the base column 201 and is at least partially exposed outside the slide column 101.

[0054] Based on the above design scheme, the base post 201 is slidably mounted on the slide post 101 to realize the up and down movement of the adjustment module 2 relative to the tray 1. The base post 201 is connected to other components through the concave ball groove. The base post 201 is connected to other components through the ball joint connection. Further adjustment is achieved by using the rotation of the ball joint connection, which not only increases the adjustment methods but also increases the adjustment range to accurately obtain the jaw plane.

[0055] The slider 202 is at least partially exposed outside the slide column 101, thus acting as a handle for the convenience of medical personnel and improving the ease of operation of the adjustment module 2.

[0056] It is worth noting that there are multiple adjustment modules 2. Taking the adjustment of the arch plate 3 as an example, when one of the adjustment modules 2 moves up or down relative to the tray 1, the arch plate 3 will deflect. Furthermore, after the adjustment module 2 slides, the range of motion of the ball joint connection changes, allowing the position of the arch plate 3 to be readjusted through the ball joint connection. Repeating the above operation adjusts the position of the arch plate 3 so that its horizontal orientation is level with the patient's nasal alar-tragus line, i.e., parallel to the patient's correct jaw plane. At this point, the positions of each adjustment module 2 can be fixed, achieving the correct jaw plane.

[0057] In one possible implementation, the mandibular arch 200 also includes an arch plate 3, the bottom surface of which is connected to the tray 1 via an adjustment module 2, and the top surface of which is detachably connected to the occlusal plate 300 or the mandibular trimmer 410.

[0058] Based on the above design, the arch plate 3 serves two purposes: firstly, it acts as a connector to fix the occlusal plate 300 or the mandibular guide 410 onto the mandibular arch 200; secondly, it is used to display the position of the occlusal plane. That is, by adjusting the adjustment module 2, the arch plate 3 is made parallel to the patient's occlusal plane, thereby achieving the goal of obtaining the correct occlusal plane.

[0059] In a straightforward manner, similar to tray 1, the arch plate 3 is designed based on the obtained initial patient impression to achieve personalized customization and improve the accuracy of relevant data acquisition.

[0060] In addition, such as Figure 2 As shown, to facilitate quick and easy connection between the engagement piece 300 and the undercarriage piece 410, a fixing post is provided on the top surface of the bow plate 3. Correspondingly, the engagement piece 300 and the undercarriage piece 410 are provided with matching fixing grooves. Based on this, connection can be achieved by the cooperation of the fixing post and the fixing groove, and conversely, separation can be achieved by pulling the fixing post out of the fixing groove. The structure is simple and the operation is convenient.

[0061] Furthermore, the bow plate 3 is provided with an inner groove, and the fixing post is located in the inner groove. At this time, when the bow plate 3 is connected to the engagement piece 300 or the lower guide piece 410, the height of the outward protrusion of the engagement piece 300 and the lower guide piece 410 is smaller.

[0062] It is noteworthy that when the digital Gothic arch device is used to obtain a closed-mouth impression, both the maxillary arch 100 and the mandibular arch 200 are equipped with occlusal plates 300. The mandibular arch 200 is connected to the occlusal plate 300 or a tracing element via an arch plate 3. Depending on clinical practice, the occlusal plate 300 may also be connected to the maxillary arch 100 if necessary.

[0063] In one possible implementation, the occlusal plate 300 is constructed in an arc shape to fit the arch plate 3, and the minimum thickness of the occlusal plate 300 is 0.5 mm, and the thickness increases in increments of 0.5 mm to form a thickness step.

[0064] Based on the above design, the occlusal plate 300 is used to compensate for the gap between the arch plate 3 and the upper retainer 420 to achieve the purpose of closed-mouth impression. Furthermore, the occlusal plate 300, by forming a thickness stepped structure, allows medical personnel to select an appropriate thickness, thereby improving the accuracy of the closed-mouth impression.

[0065] Specifically, the patient's vertical distance is confirmed using common methods such as the resting jaw gap method or the facial proportion equal division method. Based on the vertical distance, an occlusal interphalangeal joint 300 of corresponding thickness is selected so that the sum of the thicknesses of the upper and lower occlusal interphalangeal joints 300 equals the vertical distance.

[0066] It is worth noting that the recording device includes a lower recording device 410 and an upper recording device 420. When the digital Gothic bow device is used to obtain the centric jaw relationship, the mandibular bow 200 is provided with a lower recording device 410 for obtaining the mandibular movement trajectory, and the maxillary bow 100 is provided with an upper recording device 420 for recording the mandibular movement trajectory and obtaining the trajectory apex.

[0067] Specifically: In one possible implementation, the lower drawing member 410 includes a drawing plate 411 and a marking screw 412. The two ends of the drawing plate 411 are used to connect the bow plate 3. The middle part of the drawing plate 411 is provided with a marking hole adapted to the marking screw 412. The marking screw 412 is detachably set on the marking hole. Correspondingly, the length of the marking screw 412 extending out of the drawing plate 411 is equal to the thickness of the selected engagement piece 300. The marking hole is constructed as a screw hole.

[0068] Based on the above design, the lower tracing element 410 is connected to the arch plate 3 via the tracing plate 411, thereby fixing the lower tracing element 410 to the mandibular arch 200. The upper end of the tracing screw 412 extends to the top surface of the tracing plate 411 until the upper end of the tracing screw 412 lightly touches the upper tracing element 420. When the patient performs mandibular movements, the upper end of the tracing screw 412 moves along the upper tracing element 420, so that the upper tracing element 420 records the trajectory of the mandibular movements.

[0069] The pitch of the marking screw 412 is controllable. During the process of the marking bolt passing through the marking hole, the number of rotations of the marking screw 412 can be recorded to control the length of the marking screw 412 that passes through, so as to accurately achieve the purpose of the upper end of the marking screw 412 lightly touching the upper marking member 420.

[0070] Preferably, after the occlusal plate 300 is used, the height of the tracing screw 412 is controlled based on the obtained vertical distance, that is, the length of the tracing screw 412 protruding from the tracing plate 411 is equal to the thickness of the selected occlusal plate 300, to ensure ease of operation. Based on this, if a closed-mouth impression and centric jaw relationship are to be obtained simultaneously, the occlusal plate 300 is first installed on the mandibular arch 200, and then the lower tracing piece 410 is installed.

[0071] In one possible implementation, the upper recording component 420 includes a recording plate 421 and a card plate 422. The top surface of the recording plate 421 is connected to the tray 1 via the adjustment module 2, and the bottom surface of the recording plate 421 is detachably connected to the card plate 422. The card plate 422 is provided with an adjustment groove for adjusting the position of the card plate 422 relative to the recording plate 421 and a recording hole for recording the position of the recording screw 412. Correspondingly, a fixing screw for connecting the recording plate 421 and the card plate 422 is provided through the adjustment groove, and the recording hole is adapted to the recording screw 412.

[0072] Based on the above design, the upper recording element 420 is connected to the maxillary arch 100 via the recording plate 421, and the position of the recording plate 421 is adjusted by the adjustment module 2. When the lower recording element 410 moves with the patient's mandibular movement, the recording plate 421 records the trajectory of the mandibular movement. Medical personnel can determine the vertex of the trajectory based on the mandibular movement trajectory on the recording plate 421. At this time, the locking plate 422 is installed on the recording plate 421, and the position of the locking plate 422 is adjusted by the adjustment groove until the upper end of the recording screw 412 is inserted into the recording hole of the locking plate 422, thereby locking the position of the recording screw 412, thus realizing the recording of the positional relationship of the upper and lower jaws under the centric maxillary position.

[0073] In one possible implementation, the recording plate 421 has an outwardly extending facebow connection structure 4 at its outward-facing end. Based on the above design, the recording plate 421 is connected to the facebow's universal joint via the facebow connection structure 4, thereby recording the position of the maxilla relative to the temporomandibular joint. Thus, the patient's jaw position is accurately recorded using the digital Gothic bow device, facilitating the subsequent accurate transfer of the patient's jaw position.

[0074] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
