Description

Technical Field

[0001] The present invention relates to the field of oral medical treatment, and in particular to a manufacturing method of a digital snoring prevention device and the snoring prevention device. Background Art

[0002] For physical therapy of patients with mild / moderate snoring and obstructive sleep apnea-hypopnea syndrome, in addition to surgery and positive pressure ventilation, various snoring devices are also commonly used. They pull the mandible to a protruding position to expand the airway and eliminate obstruction symptoms.

[0003] The traditional manual production process for snoring devices is cumbersome. Obtaining the occlusal relationship alone involves multiple steps, including taking impressions with molding materials, casting plaster models, obtaining bite wax records, and installing an articulator. This is not only time-consuming but also overly reliant on the practitioner's experience, inevitably introducing artifacts that can affect treatment outcomes. In the field of digital customization, reconstructing the occlusal relationship remains a significant challenge. Both the requirements for equipment like electronic facebows and the complexity of cutting and processing occlusal replicas hinder clinical adoption. For example, digital processing is not yet fully implemented in removable dentures due to the need for impressions with molding materials, casting plaster models, and installing an articulator before fabrication. Furthermore, designs based on intraoral digital scanning often focus on determining the patient's personalized mandibular motion trajectory, such as protrusion and lateralization. This requires extensive computational effort, and a simple and reliable solution for accurately obtaining the patient's centric jaw position remains lacking. Summary of the Invention

[0026] <Manufacturing method of digital anti-snoring device>

[0027] In order to solve the above problems, Figure 1 1 is a flow chart of a method provided by an exemplary embodiment of the present invention, comprising the following steps:

[0028] Step S1, obtaining initial three-dimensional data of the maxillary dentition and the mandibular dentition;

[0029] Step S2, confirming the midline position of the upper and lower front teeth when the upper and lower front teeth are occluded in the centric jaw position by making the upper and lower front teeth occlude the upper and lower jaw pads of the jaw pad;

[0030] Step S3, in the mandibular protrusion position with the midlines of the upper and lower front teeth aligned, obtaining a reference mandibular protrusion amount and a matching occlusal opening amount corresponding to the specifications of the snoring device to be manufactured, and fixing the positional relationship between the upper and lower tooth pads at this time;

[0031] Step S4, reconstructing final three-dimensional data of the maxillary dentition and the mandibular dentition by scanning the oral cavity and combining the initial three-dimensional data with the upper and lower front teeth occluding the jaw pad with a fixed position relationship;

[0032] Step S5: manufacturing a snoring suppressor having the reference mandibular protrusion amount and the matching bite opening amount based on the final three-dimensional data.

[0033] In step 1 (and step 4), a 3D scanner, such as a 3-shape oral scanner, can be used to scan the patient's maxillary and mandibular dentition separately. This allows for intraoral scanning and model reconstruction to create a 3D virtual model of the entire dentition. Furthermore, during follow-up visits, data saved from previous scans, such as a full dentition model exported in STL format, can be used as needed. This is not limited to these methods; CBCT and other methods can also be used to obtain 3D medical image data of the patient's oral cavity.

[0034] In step S2, for example Figure 2 The jaw pad 1 for auxiliary occlusal recording in the anterior teeth area shown is folded back to back via the bending portion 12 and placed in the patient's mouth, so that the incisal edges of the upper and lower anterior teeth are respectively bitten into the groove 4 between the labial upper groove wall 10 and the lingual upper groove wall portion 8, and the groove 5 between the labial lower groove wall 11 and the lingual lower groove wall portion 9. In the initial occlusal position of the upper and lower anterior teeth, that is, the centric jaw position when the upper top surface 15 of the lower tooth pad 3 and the lower bottom surface 16 of the upper tooth pad 2 are in contact with each other, the doctor can determine the dentition midline that is basically aligned with the patient's facial midline through the perspective structural portions 6 and 7 formed respectively on the labial upper groove wall 10 and the labial lower groove wall 11, or by observing the anterior teeth 3-3 and combining the surrounding positions, so as to mark and record the midline positions of the upper and lower anterior teeth in the centric jaw position.

[0035] Specifically, the jaw pad 1 can be integrally formed from a flexible base material into a roughly elliptical or track-shaped outer contour, and the labial upper groove wall 10 and the labial lower groove wall 11 are formed into two arc segments rising from the two curved sides of the base material, extending left and right to the position for accommodating the front teeth 3-3, so that their inner circumferential walls can respectively make envelope-type contact with the incisal edges of the upper and lower front teeth. The perspective structural parts 6 and 7 only need to be structures that allow the doctor to observe the midline position of the front teeth in the central jaw position inside the mouth from the outside. For example, they can be constructed as hole portions that pass through the labial upper groove wall 10 and the labial lower groove wall 11 respectively, or as groove portions that are recessed from the top or bottom edges of the labial upper groove wall 10 and the labial lower groove wall 11 to the side of the groove wall body, or directly constructed of a transparent material. Optionally, as Figure 3 As shown, when the patient adjusts the jaw position according to the doctor's instructions, the doctor can clearly identify the midline positions of the upper and lower front teeth through the perspective structural parts 6 and 7, so that the pair of midline positions can be marked in the initial occlusal position, for example, using a marker pen, or with the help of scale lines (not shown) attached to the jaw pad 1.

[0036] like Figure 4 As shown, the bottom wall thickness t of each groove 4, 5 is approximately 1.0mm to 2.0mm and has a flat bottom surface. For example, when t is 1mm, the overlapping thickness of the two bottom walls in the initial occlusal position is 2mm. Therefore, the upper and lower front teeth are separated by the jaw pad 1 in the Z direction by 2mm (also known as the occlusal opening amount). This can prevent the upper and lower front teeth from being bitten by the incisal edges F1 and F2, while also minimizing the distance between the upper and lower front teeth and contouring the initial occlusal position. The wall thickness of other parts is approximately 1mm to 4mm, and the bend 12 (see Figure 2 The material thickness (in the dotted area) preferably does not exceed the thickness of the substrate on either side to facilitate bending. One side of the lower tooth pad 3 and one side of the upper tooth pad 2 are roughly symmetrical about the bending portion 12, and the width (the span direction for bending) of the bending portion 12 is sized to allow the lower tooth pad 3 to extend forward relative to the upper tooth pad 2 to the maximum mandibular protrusion position. Here, the lingual upper groove wall 8 and the lingual lower groove wall 9 can be formed, for example, by molding, as protrusions bulging from the surface of the substrate, and can each have a thickness that gradually decreases as it approaches the grooves 4 and 5. Although not shown, a forwardly extending handle, such as a slat, can also be provided on the outer peripheral walls of the labial upper groove wall 10 and the labial lower groove wall 11 to facilitate operation.

[0037] In step S3, when the patient extends the mandible forward as instructed by the doctor, while keeping the midlines of the upper and lower anterior teeth aligned, the maximum protrusive distance Ukmax of the mandible is measured (= the horizontal distance from the incisal edge of the lower anterior teeth to the labial surface of the incisal edge of the upper incisor in the centric jaw position + the horizontal distance from the incisal edge of the lower incisor to the incisal edge of the upper incisor in the maximum protrusive position).

[0038] Then, the patient is asked to retract the mandible to the reference mandibular protrusion Uk (≈Ukmax*60%), and adjust it to the matching bite opening Om based on appropriate opening and closing movements. These two values ​​will be used to determine the specifications of the snoring device to be manufactured, corresponding to the mandibular protrusion position at which the current patient can comfortably wear the snoring device to achieve the therapeutic effect.

[0039] For example, if the maximum protrusion distance Ukmax is measured to be 8 mm, Ukmax * 60% = 8 * 60% = 4.8 mm, and the reference mandibular protrusion distance Uk = 4 mm can be temporarily used. The mandibular protrusion distance can be indicated by a scale line (not shown) on the top surface of the lower tooth pad 3 (or the sloped surface 14 described later).

[0040] By repeating this action and asking the patient whether he feels any discomfort, after finding the most comfortable reference mandibular protrusion and matching bite opening, use a fast-setting curing material, such as heated wax, to fix this position.

[0041] A chamfered or rounded slope portion 14 facing the corresponding labial lower groove wall 11 (or labial upper groove wall 10) can be provided on the upper top surface 15 of the lower jaw pad 3 (or the lower bottom surface 16 of the upper jaw pad 2) so that the above-mentioned curing material can be quickly filled into the expanded portion 13 for curing, thereby forming a temporary orthodontic appliance by the jaw pad 1 and the curing material.

[0042] In step S4, the patient is asked to lie flat and wear the temporary appliance for about ten minutes. If it is confirmed that there is no discomfort, the occlusal relationship of the left and right posterior teeth can be scanned intraorally without the temporary appliance to obtain the final three-dimensional data.

[0043] In this process, the three-dimensional morphology of the posterior teeth on the left and right sides of the temporary appliance can be fused with the initial three-dimensional data to reconstruct a three-dimensional virtual model corresponding to the most comfortable reference mandibular protrusion and matching bite opening amount, such as Figure 5 As shown, the final three-dimensional data can be derived therefrom.

[0044] In step S5, for example, the final three-dimensional data can be sent to a processing institute by editing an email, and a manufacturing model can be generated through computer-aided design. For example, domestic resin materials can be used for cutting and manufacturing the snoring device. Three-dimensional printing can also be performed based on the three-dimensional virtual model to obtain a resin model until it feels comfortable when put into the mouth.

[0045] For example, in the above step S3, there may be a situation where the patient cannot accurately feel the most comfortable position due to on-site interference, or the snoring device may be deformed due to long-term wearing and need to be replaced. Therefore, after step S5, it is possible to return to and repeat the above steps S2 to S5, and a different (for example, adjacent model) jaw pad can be selected at this time. For example, six models #1 to #6 can be set: #1 is a jaw pad with a bite opening of 2mm, the incisal edges of the upper anterior teeth and the lower anterior teeth in an end-to-end position, and the mandibular advancement is minimal; #2 is a jaw pad with a bite opening of 2mm, the incisal edge of the lower anterior teeth 2mm in front of the incisal edge of the upper anterior teeth; #3 is a jaw pad with a bite opening of 2mm, the incisal edge of the lower anterior teeth 4mm in front of the incisal edge of the upper anterior teeth; #4 is a jaw pad with a bite opening of 4mm, the incisal edges of the upper anterior teeth and the lower anterior teeth in an end-to-end position; #5 is a jaw pad with a bite opening of 4mm, the incisal edge of the lower anterior teeth 2mm in front of the incisal edge of the upper anterior teeth; #6 is a jaw pad with a bite opening of 4mm, the incisal edge of the lower anterior teeth 4mm in front of the incisal edge of the upper anterior teeth.

[0046] Choose the model that best suits the patient's protrusion position from these six prefabricated jaw pads. It's recommended that new snoring preventer users start with position #2. The bite opening for each model can be achieved by setting the bottom wall thickness of each groove 4 and 5 to at least 1mm. The protrusion of the lower anterior teeth, 2mm and 4mm, can be achieved through the design of the bend 12 and can be confirmed using the scale lines mentioned above.

[0047] Place the selected jaw pad between the patient's upper and lower teeth, and ask the patient to bite the front teeth into the groove, with the labial groove wall touching the labial surface of the teeth, and the midlines of the upper and lower front teeth aligned. Then adjust a small amount of silicone rubber to fix this occlusal position (see Figure 6 In step S6, the occlusal relationship is scanned intraorally (step S4). In this way, another snoring device with similar performance can be made for the patient (step S5), increasing the use options and improving the adaptability.

[0048] As described above, step S6 can be used in place of steps S2-S3. A prefabricated jaw pad having a predetermined occlusal opening and mandibular advancement is selected. When the upper and lower front teeth are engaged with the upper and lower jaw pads of the prefabricated jaw pad, the positional relationship between the upper and lower jaw pads is fixed in the mandibular advancement position with the midlines of the upper and lower front teeth aligned. This allows for the rapid formation of a temporary orthodontic appliance through appropriate selection. Furthermore, based on the design of the flexible substrate and the bend 12, appropriate adjustments are still permitted before fixation to achieve the aforementioned reference mandibular advancement and matching occlusal opening.

[0049] In addition, between the above steps S1 and S2 , step S0 may be performed, wherein the initial three-dimensional data scanned in step S1 is sent, for example, by email to a processing institute to produce a personalized jaw pad 1 .

[0050] <Technical Effects>

[0051] According to the present invention, the following advantages can be achieved: the entire process is digitized, and there is no excessive reliance on the experience of doctors and technicians, which facilitates the promotion and application of this technology; errors caused by improper mixing of materials, improper water-powder ratio, storage and transportation wear and tear during the process of taking impressions and pouring models are avoided during production, thereby increasing accuracy and ensuring quality; the jaw pad and snoring device are small in size and have high dimensional accuracy, which increases comfort and is easier for patients to accept. The use of wax, silicone rubber, etc. for fixation can quickly and effectively prevent the upper and lower dental pads 2 and 3 from being misaligned from the midline alignment state, and can be used for re-oral scanning to obtain the final three-dimensional virtual model. Using adhesive materials such as photosensitive resins, powdered metals or plastics, 3D printing based on digital model files does not require the use of molds, saves labor time, and is conducive to the rapid preparation of snoring devices.

[0052] Thus, the present invention provides a method for reconstructing the occlusal relationship of a digital jaw pad based on the visual alignment of the midlines of the upper and lower anterior teeth, thereby realizing a digitally designed, additively manufactured snoring device with high quality, efficiency, and precision. The jaw pad's markings or scale lines are used to assist in recording the occlusal relationship. Based on the patient's actual experience, the device can be generated through 3D printing using the final three-dimensional data, which is what you see is what you get. This satisfies personalized requirements in advance without the need for trial-type adjustments. With the midline position of the upper and lower anterior teeth fixed and aligned, there is no need to simulate the movement of the dentition and joints, and the amount of computational operations is minimal. The use of perspective structural parts 6 and 7 eliminates the need for multi-directional observation, greatly simplifying the doctor's operation. Recording the centric and protrusive occlusal relationship of the upper and lower jaws is more accurate, and the mapping relationship is simple and reliable. After sample production and intraoral trial wear testing, the snoring device was found to be suitable for a comfortable mandibular protrusive position and has good stability, showing excellent clinical feasibility and application prospects.

[0053] Although the present invention has been described with reference to various specific embodiments, it will be appreciated that modifications may be made within the spirit and scope of the inventive concepts described. It is intended, therefore, that the present invention not be limited to the embodiments described, but will have the full scope defined by the language of the appended claims.
