Abstract
Description
Technical Field
[0001] This utility model relates to a jaw position guide calibration ruler, belonging to the field of oral medical technology. Background Technology
[0002] Currently, orthodontic treatment involving dental instruments such as braces and retainers is considered a potential treatment option for obstructive sleep apnea (OSA). Jaw retainers can help adjust the position of the jaw and tongue, thereby helping to open the airway and alleviate obstructive sleep apnea. Existing dental instruments for OSA treatment require personalized customization based on the patient's jaw position data, which necessitates the use of intraoral scanning instruments or other methods to collect this data.
[0003] After a patient begins wearing orthodontic appliances, titration is required to adjust the jawline for optimal therapeutic effect. Titration is performed by an experienced dentist or oral surgeon. Specific titration values cannot be determined during titration, and multiple titrations may not accurately establish the jawline relationship. Adjustments are made every few weeks based on patient tolerance, with each increase not exceeding 1mm, until the maximum comfortable range / applied appliance limit is reached. Patient tolerance is the primary factor determining the appropriate degree and speed of mandibular advancement. In most patients, tolerance gradually increases.
[0004] After searching the existing technology, it was found that Chinese patent CN213640862U discloses a mandibular protrusion measuring ruler. Although the device can measure the distance of mandibular protrusion, it is cumbersome to operate, requires multiple insertions and removals, and increases patient discomfort. In addition, multiple insertions and removals may cause the patient to be measured in an unstable jaw position. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a jaw position guide calibration ruler that can simplify operation, adapt to different patients, and improve patient comfort.
[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a jaw position guide calibration ruler, comprising:
[0007] The jaw position guide calibration ruler body is a sheet-like structure extending along the length direction. The upper surface of the jaw position guide calibration ruler body forms an upper incisor contact surface suitable for contacting the maxillary incisors, and the lower surface of the jaw position guide calibration ruler body forms a lower incisor contact surface suitable for contacting the mandibular incisors. Multiple upper incisor positioning protrusions are spaced apart along the length direction on the upper incisor contact surface, and multiple lower incisor positioning protrusions are spaced apart along the length direction on the lower incisor contact surface. The upper incisor positioning protrusions and the lower incisor positioning protrusions are symmetrically arranged with respect to the central axis extending along the length direction of the jaw position guide calibration ruler body.
[0008] Furthermore, in order to better fit the teeth, the upper incisor positioning protrusion is provided with an upper incisor fitting surface that matches the inner side of the upper incisor, and the lower incisor positioning protrusion is provided with a lower incisor fitting surface that matches the inner side of the lower incisor.
[0009] Furthermore, the extended surface of the upper incisor contact surface of the jaw position guide calibration ruler body intersects with the extended surface of the lower incisor contact surface to form an angle.
[0010] Furthermore, at least one side of the jaw position guide calibration ruler body is provided with multiple scale marks corresponding to thickness information at intervals along the length direction.
[0011] Furthermore, the distance between adjacent upper incisor positioning protrusions along the length direction on the occlusal position guide calibration ruler body ranges from 0.5mm to 5mm, and the distance between adjacent lower incisor positioning protrusions along the length direction on the occlusal position guide calibration ruler body ranges from 0.5mm to 5mm.
[0012] Furthermore, between the adjacent upper incisor positioning protrusions on the occlusal position guide calibration ruler body, located on the left and right sides of the upper incisor positioning protrusions, a first prefabricated breakage groove is provided on the sheet-like structure of the occlusal position guide calibration ruler body.
[0013] Between the adjacent lower incisor positioning protrusions on the occlusal guide calibration ruler body, located on the left and right sides of the lower incisor positioning protrusions, a second prefabricated breakage slot is provided on the sheet-like structure of the occlusal guide calibration ruler body.
[0014] The first pre-made break-off slot and the second pre-made break-off slot are aligned laterally on the jaw position guide calibration ruler body and form a pre-made break-off slot that penetrates the jaw position guide calibration ruler body.
[0015] Furthermore, the jaw position guide calibration ruler body is integrally formed.
[0016] Furthermore, one end of the jaw position calibration ruler body is provided with a handle.
[0017] Furthermore, the end of the handle that is away from the jaw position guide calibration ruler body is provided with an end structure with a rounded transition.
[0018] Furthermore, the end of the jaw position guide calibration ruler body away from the handle is provided with an end structure with a rounded transition.
[0019] By adopting the above technical solution, this utility model has the following beneficial effects:
[0020] This invention utilizes a sheet-like structure extending along its length to allow the jaw position guide calibration ruler to be stably placed between the user's maxillary and mandibular incisors. During occlusion, the upper incisor contact surface contacts the maxillary incisor, and the lower incisor contact surface contacts the mandibular incisor. The upper incisor positioning protrusions align with the maxillary incisors, and the lower incisor positioning protrusions align with the mandibular incisors. Furthermore, during jaw occlusion, the jaw position guide calibration ruler provides counteracting tension through the symmetrically distributed upper and lower incisor positioning protrusions, maintaining stable jaw position guidance for the user. This ensures stability of the user's jaw opening and closing state under different jaw position guidance requirements, avoids measurement errors caused by occlusal deviation, improves the accuracy of jaw position guidance, and ensures the reliability of jaw position guidance calibration.
[0021] Furthermore, the extended surfaces of the upper incisor contact surface and the lower incisor contact surface of the jaw position guide ruler intersect to form an angle, allowing different users to match corresponding upper and lower jaw opening and closing volumes under the same jaw position guide volume, thus providing better stability of jaw opening and closing status. At least one side of the jaw position guide ruler has multiple graduations along its length, corresponding to thickness information, allowing users to intuitively read the jaw opening and closing volume during occlusion, facilitating numerical estimation and improving measurement accuracy. Simultaneously, the pre-fabricated break-off slot of the jaw position guide ruler body allows users to adjust the length of the ruler by bending it when jaw opening and closing volume requirements change, preventing the ruler from occupying too much space in the oral cavity and affecting comfort, thus improving ease of use. A handle is provided at one end of the jaw position guide ruler body, making it easier for users to hold and adjust during operation, further improving stability and comfort. Both the end of the handle furthest from the jaw position guide calibration ruler body and the end of the jaw position guide calibration ruler body furthest from the handle adopt a rounded end structure to reduce irritation to the oral soft tissues during use and improve wearing comfort.
[0022] In summary, this invention is stable and easy to use, effectively helping users stabilize their jaw opening and closing state under different lead-ahead volume requirements, while providing accurate measurement of jaw opening and closing volume, and has good clinical application value.

[0032] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0033] like Figure 1-9 As shown, a jaw position guide calibration ruler includes:
[0034] The jaw position guide calibration ruler body 1 is a sheet-like structure extending along the length direction. The upper surface of the jaw position guide calibration ruler body 1 forms an upper incisor contact surface 11 suitable for contacting the upper incisors, and the lower surface of the jaw position guide calibration ruler body 1 forms a lower incisor contact surface 12 suitable for contacting the lower incisors. Multiple upper incisor positioning protrusions 111 are spaced apart along the length direction on the upper incisor contact surface 11, and multiple lower incisor positioning protrusions 121 are spaced apart along the length direction on the lower incisor contact surface 12. The upper incisor positioning protrusions 111 and the lower incisor positioning protrusions 121 are symmetrically arranged with respect to the central axis extending along the length direction of the jaw position guide calibration ruler body 1.
[0035] In this embodiment, as Figure 1-2 and Figure 5-9As shown, the sheet-like structure is first placed between the user's maxillary and mandibular incisors. When the user bites, the maxillary incisor contact surface 11 contacts the maxillary incisor, the mandibular incisor contact surface 12 contacts the mandibular incisor, the maxillary incisor positioning protrusion 111 fits against the maxillary incisor, and the mandibular incisor positioning protrusion 121 fits against the mandibular incisor. During the biting process of the maxillary and mandibular incisors, the occlusal guidance calibration ruler body 1 provides counteracting tension through the symmetrically distributed maxillary incisor positioning protrusions 111 and mandibular incisor positioning protrusions 121 to maintain the stability of the user's occlusal guidance. This ensures the stability of the user's maxillary and mandibular open / closed state under different occlusal guidance requirements, avoids measurement errors caused by occlusal deviation, improves the accuracy of occlusal guidance, and ensures the reliability of occlusal guidance calibration.
[0036] Specifically, such as Figure 1-2 As shown, the upper incisor positioning protrusion 111 is provided with an upper incisor fitting surface 112 that is adapted to the inner side of the upper incisor, and the lower incisor positioning protrusion 121 is provided with a lower incisor fitting surface 122 that is adapted to the inner side of the lower incisor.
[0037] In this embodiment, as Figure 1-2 As shown, the end of the upper incisor positioning protrusion 111 is curved to form an upper incisor mate surface 112, and the end of the lower incisor positioning protrusion 121 is curved to form a lower incisor mate surface 122.
[0038] Specifically, such as Figure 1-2 and Figure 5-9 As shown, the extended surface of the upper incisor contact surface 11 of the jaw position guide calibration ruler body 1 intersects with the extended surface of the lower incisor contact surface 12 to form an angle.
[0039] Specifically, such as Figure 1-2 As shown, multiple scale marks 15 corresponding to thickness information are provided at intervals along the length direction on both sides of the jaw position guide calibration ruler body 1.
[0040] In this embodiment, as Figure 1-2 and Figure 4 As shown, the angle formed by the intersection of the extended surfaces of the upper incisor contact surface 11 and the lower incisor contact surface 12 is α. The range of α can be between 1 degree and 45 degrees, preferably 7 degrees. The upper and lower incisor contact surfaces of the occlusal guidance calibration ruler body form a certain angle, allowing the calibration ruler to adapt to different occlusal states under different occlusal guidance requirements. At least one side edge of the occlusal guidance calibration ruler body has graduation marks along its length. These graduation marks correspond to different thickness information and are used to provide a visual reference during measurement. The graduation marks are arranged along the side edge of the calibration ruler body, allowing the user to intuitively judge the occlusal open / closed state during observation. In some embodiments, the range of α is not limited to 7 degrees and can be set according to specific needs.
[0041] Specifically, such as Figure 1-2 and Figure 5-9 As shown, the spacing between adjacent upper incisor positioning protrusions 111 along the length direction on the jaw position guide calibration ruler body 1 ranges from 0.5 mm to 5 mm, and the spacing between adjacent lower incisor positioning protrusions 121 along the length direction on the jaw position guide calibration ruler body 1 ranges from 0.5 mm to 5 mm.
[0042] In this embodiment, the specific spacing can be set to 1mm or 2mm. In some embodiments, the spacing is not limited to 1mm or 2mm and can be set according to specific needs.
[0043] Specifically, such as Figure 1-3 and Figure 5-9 As shown, between the adjacent upper incisor positioning protrusions 111 on the jaw position guide calibration ruler body 1, on the left and right sides of the upper incisor positioning protrusions 111, a first prefabricated breakage slot is provided on the sheet-like structure of the jaw position guide calibration ruler body 1.
[0044] Between the adjacent lower incisor positioning protrusions 121 on the occlusal position guide calibration ruler body 1, on the left and right sides of the lower incisor positioning protrusions 121, a second prefabricated breakage slot is provided on the sheet-like structure of the occlusal position guide calibration ruler body 1.
[0045] Among them, the first prefabricated breakage slot and the second prefabricated breakage slot are aligned in the transverse direction of the jaw position guide calibration ruler body 1 and form a prefabricated breakage slot 14 that penetrates the jaw position guide calibration ruler body 1.
[0046] In this embodiment, as Figure 1-3 and Figure 5-9 As shown, when in use, if the user's jaw position guidance amount needs are different, the calibration ruler body can be broken along the pre-made breakage slot as needed to adjust the length of the calibration ruler to adapt to different jaw position calibration needs.
[0047] Furthermore, the design of the pre-fabricated break-off slots 14 allows the length of the jaw position guide ruler body 1 to be adjusted according to the user's actual needs. When the user only needs a specific length of jaw position guide ruler, the unnecessary part can be broken off and removed through these pre-fabricated break-off slots 14. This also avoids discomfort caused by placing too much of the jaw position guide ruler in the oral cavity due to its excessive length. The pre-fabricated break-off slots 14 penetrate through the jaw position guide ruler body 1, allowing the operator to apply force along the pre-fabricated slots to achieve standardized cutting of the jaw position guide ruler body 1.
[0048] Specifically, such as Figure 1 and Figure 5-9 As shown, the jaw position guide calibration ruler body 1 is integrally formed.
[0049] Specifically, such as Figure 1-3 and Figure 5-9 As shown, one end of the jaw position calibration ruler body 1 is provided with a handle 16.
[0050] Specifically, such as Figure 1-3 and Figure 5-9 As shown, the end of the handle 16 away from the jaw position guide calibration ruler body 1 is provided with an end structure with a rounded transition.
[0051] Specifically, such as Figure 1-3 and Figure 5-9 As shown, the end of the jaw position guide calibration ruler body 1 away from the handle 16 is provided with an end structure with a rounded transition.
[0052] In this embodiment, as Figure 1-3 and Figure 5-9 As shown, one end of the jaw position measurement ruler body 1 is provided with a handle 16, which is used by the user for hand control during operation. The end of the handle 16 away from the jaw position measurement ruler body adopts a rounded transition structure to reduce discomfort to the hand from the edge. The end of the jaw position measurement ruler body away from the handle also adopts a rounded transition end structure to avoid irritation to the oral soft tissues. Figure 7-9 Different lead amounts are generated for different occlusal schemes.
[0053] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
