Description

Technical Field

[0001] This invention relates to the field of dental braces manufacturing, and more specifically to a pressure film device for dental braces film manufacturing and its usage method. Background Technology

[0002] Orthodontic aligners are a series of completely transparent, thin-shell-like devices made of medical-grade polymer materials. Each aligner is precisely manufactured based on a digital three-dimensional model of the patient's teeth, and can tightly wrap around the entire row of teeth.

[0003] In patent application CN218053743U, published on 2022-12-16, entitled "A Braces Forming Device for Orthodontic Treatment," this invention discloses a braces forming device for orthodontic treatment, including a first forming mold block, a second forming mold block connected to the lower end of the first forming mold block, limit blocks fixedly provided on both the front and rear sides of the lower end of the first forming mold block, limit grooves fixedly provided on both the front and rear sides of the upper end of the second forming mold block, a sealing gasket fitted between the first and second forming mold blocks, and an injection port fixedly provided at the middle of the front end between the first and second forming mold blocks. This invention forms a corrective brace in the forming groove by pressing a sealing gasket between the first and second forming mold blocks, and by fixing an injection port at the middle of the front end between the first and second forming mold blocks. A rubber plug is then inserted into the injection port. Thus, both the sealing gasket and the rubber plug prevent the plastic material from overflowing from the forming groove.

[0004] In the aforementioned patents or prior art, commonly used braces require periodic adjustments to their shape or internal structure based on the patient's orthodontic progress. However, because these transparent braces, manufactured using membrane processing technology, are often produced in a single molding process, each adjustment often necessitates re-molding and remaking the braces. This process not only prolongs the treatment period but also significantly increases the patient's treatment costs.

[0005] Therefore, it is necessary to invent a pressure film device for dental brace film processing and its usage method to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a molding device for dental brace film processing and its usage method. By combining an independently adjustable dental mold structure with air-assisted molding, it solves the problems of prolonged orthodontic cycle and high treatment cost caused by the need for secondary molding to adjust the shape of dental braces in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a pressure film device for processing dental braces film, comprising a base, guide columns symmetrically mounted above the base, a top seat mounted above the guide columns, a sliding seat slidably connected to each set of guide columns, a hydraulic cylinder mounted between the sliding seat and the top seat, a lower mold mounted above the base, an adjustment component disposed inside the lower mold, an auxiliary forming component disposed above the lower mold, an upper mold disposed below the sliding seat, and an injection port throughly connected to one side of the upper mold.

[0008] In a preferred embodiment of the present invention, the adjusting component includes a sliding cavity, which is arc-shaped and opened in the lower mold. A connecting cavity is opened between the upper part of the inner wall of each group of sliding cavities and the top of the lower mold, and a through hole is opened between the upper part of the inner wall of each group of sliding cavities and the side of the lower mold.

[0009] As a preferred embodiment of the present invention, each group of sliding cavities is provided with a sliding block, and a telescopic guide rod is installed between one side of each group of sliding blocks and the inner wall of the sliding cavity. Each group of connecting cavities is rotatably connected with a rotating plate.

[0010] As a preferred embodiment of the present invention, each group of rotating plates is provided with a symmetrical groove below, and each group of sliding blocks is provided with a slider symmetrically mounted above, and the slider is slidably connected to the corresponding groove.

[0011] As a preferred embodiment of the present invention, each group of through holes is equipped with an internally threaded sleeve, and each group of internally threaded sleeves is threaded with a bolt through it, and the bolt is rotatably connected to the corresponding sliding block.

[0012] As a preferred embodiment of the present invention, each group of bolts is fitted with a graduated cylinder for limiting, each group of graduated cylinders is symmetrically equipped with a guide block, and each group of through holes is symmetrically provided with a guide groove on the inner wall, and the guide groove is slidably connected with the corresponding guide block.

[0013] In a preferred embodiment of the present invention, the auxiliary forming component includes a limiting cavity, which is opened above each group of rotating plates. A connecting rod is connected through each group of limiting cavities, and a connecting ring is installed below each group of connecting rods.

[0014] As a preferred embodiment of the present invention, a fixing block is installed below each of the connecting rings, and multiple sets of fixing holes are provided in a ring shape below the inner wall of each of the limiting cavities, and the fixing blocks are engaged with the corresponding fixing holes. A spring is sleeved on each of the connecting rods, and the two ends of the spring are respectively attached to the upper part of the connecting ring and the inner wall of the limiting cavity.

[0015] As a preferred embodiment of the present invention, a dental mold is installed above each of the connecting rods, and the dental molds are arranged in an arc shape. An annular airbag is installed on the base, and the annular airbag surrounds each dental mold in an annular shape. An air supply pipe is installed on one side of the base, and the air supply pipe is connected to the inside of the annular airbag.

[0016] A method of using a pressure-forming device for dental brace film processing, employing any one of the above-described pressure-forming devices for dental brace film processing, includes the following steps:

[0017] S1: Based on the patient's current orthodontic data, rotate the corresponding bolt to move the sliding block, and then adjust the corresponding dental model to the target position via the rotating plate; if it is necessary to adjust the circumferential angle of the dental model, gently pull upward and rotate the dental model, and release it after adjustment to lock it automatically. Position all dental models one by one in this way to ensure their alignment meets the requirements of the current orthodontic stage. S2: Start the hydraulic cylinder, drive the sliding seat to move the upper mold down, close with the lower mold, and completely cover the positioned dental mold; S3: Inflate the annular airbag through the air supply tube, causing it to expand and tightly fill the gaps between the dental molds; S4: The molding material is injected into the cavity between the upper and lower molds through the injection port; while the material is continuously injected, the annular air bladder is gradually controlled to shrink, guiding the material to fully fill the tooth gap area, and finally completing the molding of the transparent dental crown.

[0018] Compared with the prior art, the technical effects and advantages provided by the present invention in the above technical solution are as follows: 1. By rotating the corresponding bolt, the dental mold is driven to move forward and backward within the internal threaded sleeve, thereby pushing the sliding block along the sliding cavity. The sliding block, through its slider engaging with the groove of the rotating plate, converts linear motion into the left-right swinging of the rotating plate within the connecting cavity, thus enabling lateral angle adjustment of the dental mold. Furthermore, the dental mold can be independently rotated by directly pulling it up; after adjustment to the desired angle, it automatically locks itself thanks to the restoring force of the spring. This structure allows for flexible and precise positional adjustments of the dental mold according to the patient's orthodontic stage, eliminating the need for re-molding required for adjustments in traditional processes, significantly reducing the cost of orthodontic treatment.

[0019] 2. By inflating the annular air bladder, it expands and fully fills the gaps between the dental molds. Simultaneously, molding material is injected into the cavity between the upper and lower molds through the injection port. During continuous material injection, the annular air bladder is gradually contracted to guide the material to tightly fill the interdental area, ensuring precise molding of the aligner in the interdental spaces and ultimately obtaining a single aligner product that closely conforms to the tooth shape.

[0023] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] This invention provides, for example Figure 1-14 The device shown is a molding device for processing dental braces film, including a base 001, guide columns 101 symmetrically mounted above the base 001, a top seat 102 mounted above the guide columns 101, a sliding seat 103 slidably connected to each set of guide columns 101, a hydraulic cylinder 104 mounted between the sliding seat 103 and the top seat 102, a lower mold 105 mounted above the base 001, an adjustment component 002 provided inside the lower mold 105, an auxiliary forming component 003 provided above the lower mold 105, an upper mold 106 provided below the sliding seat 103, and an injection port 107 connected through one side of the upper mold 106.

[0025] The upper mold 106 and the lower mold 105 can be accurately closed by the hydraulic cylinder 104 driving the sliding seat 103 to move. Then, the substrate is injected into the mold cavity through the injection port 107 to complete the forming process of the dental brace film.

[0026] Furthermore, in the above structure, the adjustment component 002 includes a sliding cavity 201, which is arc-shaped and opened in the lower mold 105. A connecting cavity 202 is opened between the upper part of the inner wall of each group of sliding cavities 201 and the top of the lower mold 105. A through hole 203 is opened between the inner wall of each group of sliding cavities 201 and the side of the lower mold 105.

[0027] By using a distribution pattern that matches the arc of the human dental arch, the sliding cavity 201 allows the device to make independent and precise adjustments to the position of a single tooth.

[0028] Furthermore, in the above structure, each set of sliding cavities 201 is provided with a sliding block 204, and a telescopic guide rod 205 is installed between one side of each set of sliding block 204 and the inner wall of the sliding cavity 201. Each set of connecting cavities 202 is rotatably connected with a rotating plate 206.

[0029] The telescopic guide rod 205 provides guidance and support for the linear movement of the sliding block 204 in the sliding cavity 201, ensuring that its movement trajectory is stable and controllable.

[0030] Furthermore, in the above structure, each set of rotating plates 206 is symmetrically provided with a sliding groove 207 below, and each set of sliding blocks 204 is symmetrically provided with a slider 208 above, and the slider 208 is slidably connected to the corresponding sliding groove 207.

[0031] The linear motion of the sliding block 204 is converted into the deflection motion of the rotating plate 206 in the connecting cavity 202 by the sliding pair formed by the slider 208 and the groove 207, thus realizing the conversion of motion form.

[0032] Furthermore, in the above structure, each set of through holes 203 is equipped with an internally threaded sleeve 210, and each set of internally threaded sleeves 210 is threaded with a bolt 209, and the bolt 209 is rotatably connected to the corresponding sliding block 204.

[0033] The threaded transmission mechanism is formed by the internal threaded sleeve 210 and the bolt 209, so that rotating the bolt 209 can precisely control the lateral displacement of the sliding block 204.

[0034] Furthermore, in the above structure, each set of bolts 209 is fitted with a scale cylinder 212 for limiting, each set of scale cylinders 212 is symmetrically equipped with a guide block 213, and each set of through holes 203 is symmetrically provided with a guide groove 211 on the inner wall, and the guide groove 211 is slidably connected with the corresponding guide block 213.

[0035] The guide groove 211 and the guide block 213 constrain the circumferential rotation of the scale cylinder 212, so that it can only move along the axial direction. Thus, the displacement of the bolt 209 can be read and recorded intuitively through the scale on the scale cylinder 212, and the swing angle of the rotating plate 206 can be indirectly calculated and recorded.

[0036] Furthermore, in the above structure, the auxiliary forming component 003 includes a limiting cavity 301, which is opened above each set of rotating plates 206. Each set of limiting cavities 301 is connected through a connecting rod 302, and a connecting ring 303 is installed below each set of connecting rods 302.

[0037] The connecting ring 303 mechanically limits the axial movement of the connecting rod 302 within the limiting cavity 301.

[0038] Furthermore, in the above structure, each set of connecting rings 303 is equipped with a fixing block 304 below it, and each set of limiting cavities 301 has multiple sets of fixing holes 309 arranged in a ring below the inner wall, and the fixing block 304 is engaged with the corresponding fixing hole 309. Each set of connecting rods 302 is fitted with a spring 305, and the two ends of the spring 305 are respectively attached to the upper part of the inner wall of the connecting ring 303 and the limiting cavity 301.

[0039] The preload provided by spring 305 ensures that the fixing block 304 and the fixing hole 309 remain stably engaged, thereby preventing the connecting rod 302 and the dental mold 306 at its upper end from rotating unexpectedly when not in an adjusted state. When adjustment is required, lifting the dental mold 306 upwards will cause the fixing block 304 to disengage from the fixing hole 309, at which point the dental mold 306 can be freely rotated to adjust its circumferential angle.

[0040] Furthermore, in the above structure, each set of connecting rods 302 is equipped with a dental mold 306, and each set of dental molds 306 is arranged in an arc shape. An annular airbag 307 is installed on the base 001, and the annular airbag 307 surrounds each set of dental molds 306 in an annular shape. An air supply pipe 308 is installed on one side of the base 001, and the air supply pipe 308 is connected to the inside of the annular airbag 307.

[0041] Inflating the annular air bladder 307 via the air supply pipe 308 allows the air bladder to expand after mold closing, tightly filling the gaps between each dental mold 306. This, combined with the molding material injected through the injection port 107, ensures that the material can fully flow into the interdental area. Subsequently, by controlling the contraction of the air bladder, the material can be precisely molded in the interdental area, thereby forming a dental crown that conforms to the tooth shape.

[0042] A method of using a pressure-pressing device for dental brace film processing, employing any of the above-mentioned pressure-pressing devices for dental brace film processing, includes the following steps: S1: Based on the patient's current orthodontic data, rotate the corresponding bolt 209 to move the sliding block 204, thereby adjusting the corresponding dental model 306 to the target position via the rotating plate 206. If it is necessary to adjust the circumferential angle of the dental model 306, gently pull upwards and rotate the dental model 306. After adjustment, release to automatically lock it in place. Position all dental models 306 one by one in this manner to ensure their alignment meets the requirements of the current orthodontic stage. S2: Start the hydraulic cylinder 104, drive the sliding seat 103 to move the upper mold 106 down, close with the lower mold 105, and completely cover the positioned dental mold 306; S3: Inflate the annular airbag 307 through the air supply pipe 308, causing it to expand and tightly fill the gaps between each dental mold 306; S4: The molding material is injected into the cavity between the upper mold 106 and the lower mold 105 through the injection port 107; while the material is continuously injected, the annular airbag 307 is gradually controlled to shrink, guiding the material to fully fill the gap area, and finally completing the molding of the transparent dental crown.

[0043] like Figure 1-14 As shown, when braces are to be fabricated, the dental mold 306 is first adjusted according to the patient's orthodontic data. The operator rotates the corresponding bolt 209, causing it to screw in or out along the internal thread sleeve 210, thereby pushing the sliding block 204 to move within the sliding cavity 201. The sliding block 204, through its slider 208, engages with the groove 207 of the rotating plate 206, converting linear motion into left and right oscillation of the rotating plate 206 within the connecting cavity 202, thus enabling the dental mold 306 to achieve lateral angle adjustment.

[0044] If the circumferential angle of the dental mold 306 needs to be adjusted, the dental mold 306 can be gently pulled upwards, causing the connecting rod 302 to move upwards, so that the fixing block 304 can be disengaged from the current fixing hole 309. Then rotate the dental mold 306 to the desired position, and after releasing it, under the action of the spring 305, the fixing block 304 will engage with the new fixing hole 309, completing the positioning.

[0045] After adjustment, the hydraulic cylinder 104 is activated to drive the sliding seat 103 to descend, causing the upper mold 106 and lower mold 105 to close, completely covering the tooth mold 306. Then, air is supplied to the annular airbag 307 through the air supply pipe 308, causing it to expand and fill the gaps between the tooth molds 306. At the same time, the raw material is injected into the closed mold cavity through the injection port 107.

[0046] During the injection process, the air pressure inside the annular airbag 307 is gradually reduced, causing it to slowly contract. This process allows the raw material to be continuously injected while gradually filling and precisely shaping the gap area of ​​the dental mold 306. Finally, after the material solidifies, it forms a single dental liner that perfectly conforms to the pre-set tooth shape.

[0047] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
