Description

Technical Field

[0001] The invention belongs to the technical field of oral medical equipment, and in particular relates to an oral implant impression taking auxiliary device. Background Art

[0002] Oral implant is a modern dental treatment method used to replace missing teeth. It implants (usually titanium alloy materials) are placed in the alveolar bone, and restorations (such as crowns, bridges or dentures, etc.) are installed on the implants, and the restorations are supported by the implants. This treatment method has significant advantages in restoring oral chewing function, improving appearance and enhancing oral health. The specific operation procedure is to open a small hole in the alveolar bone under local anesthesia, and install the implant on the alveolar bone through the small hole, so that the implant is combined with the alveolar bone of the maxillary or mandibular oral cavity. When the implant is successfully combined with the alveolar bone, a pre-made restoration is installed on the implant to restore the normal chewing function and appearance of the oral cavity.

[0003] The restoration needs to be made according to the condition of the teeth, upper and lower jaws, and gums around the implant, so that the restoration can match the patient's oral structure. Otherwise, the upper and lower jaws are prone to poor matching, resulting in uneven force on the restoration on the implant, causing the restoration to fall off or be damaged, and reducing the life of the oral implant restoration. Therefore, when making the restoration, it is necessary to use the mold material to obtain an accurate model of the teeth and gums around the implant to ensure that the restoration is matched with the surrounding oral structure.

[0004] When obtaining a model of the interior of the oral cavity, the impression material is generally placed on a impression tray, the patient opens his mouth as wide as possible, and then the impression tray is slowly placed between the upper and lower jaws into the mouth. The patient's upper or lower teeth slowly move closer to the impression material on the impression tray, and gradually squeeze the impression material to obtain a model. However, when taking impressions, some patients open their mouths at a small angle or their mouths open at a large angle but the upper and lower jaws cannot remain stable. When the impression tray is placed in the mouth, the upper or lower teeth are prone to scratching the impression material on the impression tray, resulting in impression failure. The impression material on the impression tray needs to be smoothed again and the operation needs to be repeated, resulting in poor convenience in oral implant impressions.

[0005] At present, when taking a mold for oral implants, tools are often used to assist the patient to open his mouth, actively open the patient's upper and lower jaws to the upper and lower sides, and increase the opening angle of the patient's mouth. At the same time, the upper and lower jaws can be kept stable after opening, and the teeth are prevented from scraping the molding material when the molding tray enters the mouth, thereby improving the convenience of oral implant molding. After the molding tray successfully enters the mouth, the tool needs to be separated from the teeth of the maxilla and mandible, and then the teeth of the maxilla or mandible are squeezed to squeeze the molding material to obtain a model. However, since the upper lip or lower lip of the mouth will cover the teeth and gums inside it, when the teeth of the maxilla or mandible approach the molding material to squeeze it, the upper lip and lower lip covering the teeth and gums will make it difficult to fill the molding material into each small groove or gully of the teeth and gums, so that the obtained model lacks details, reduces the accuracy of oral implant molding, and makes it difficult for the manufactured restoration to accurately match the patient's oral structure. Summary of the invention

[0019] The present invention provides an oral implant impression taking auxiliary device, Figures 1 to 6 The present invention is described with reference to the structural schematic diagram of FIG.

[0020] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the technical solutions of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] At present, when taking a mold for oral implants, tools are often used to assist the patient to open his mouth, actively open the patient's upper and lower jaws to the upper and lower sides, and increase the opening angle of the patient's mouth. At the same time, the upper and lower jaws can be kept stable after opening, and the teeth are prevented from scraping the molding material when the molding tray enters the mouth, thereby improving the convenience of oral implant molding. After the molding tray successfully enters the mouth, the tool needs to be separated from the teeth of the maxilla and mandible, and then the teeth of the maxilla or mandible are squeezed to squeeze the molding material to obtain a model. However, since the upper lip or lower lip of the mouth will cover the teeth and gums inside it, when the teeth of the maxilla or mandible approach the molding material to squeeze it, the upper lip and lower lip covering the teeth and gums will make it difficult to fill the molding material into each small groove or gully of the teeth and gums, so that the obtained model lacks details, reduces the accuracy of oral implant molding, and makes it difficult for the manufactured restoration to accurately match the patient's oral structure.

[0022] Based on the above problems, an oral implant impression assisting device provided by an embodiment of the present invention is used in conjunction with a support plate, a mounting seat and an opening hook on a bracket. When a patient performs oral implant impression taking, the opening hook on the mounting seat is used to hook the teeth of the upper and lower jaws, actively assisting the patient to open his mouth and maintaining stability, making it convenient to place the impression tray into the patient's mouth. When placing the impression tray, the teeth of the upper and lower jaws can be prevented from scratching the impression material. At the same time, when the opening hook assists the patient to open his mouth, the upper and lower lips of the patient's mouth are respectively in contact with the suction cup, and then the external negative pressure element and the suction cup are used to adjust the pressure. The tray cooperates to adsorb and fix the upper lip or lower lip. When the opening hook is separated from the teeth of the upper or lower jaw, the teeth of the upper or lower jaw approach the molding material on the molding tray for molding, which automatically separates the teeth of the upper jaw from the upper lip or the teeth of the lower jaw from the lower lip, so that the molding material is fully filled into each tiny groove or gully of the teeth and gums, thereby improving the accuracy of oral implant molding. The manufactured restoration can accurately match the patient's oral structure and ensure the effect of oral implant treatment. The molding auxiliary device of the present invention has good effect, is easy to use, has strong practicality, and is worthy of promotion.

[0023] Reference Figure 2 , Figure 2: is a front view of the mold taking auxiliary device of this embodiment, as shown in Figure 2 As shown, an oral implant model taking auxiliary device comprises a bracket 1, a support plate 2 is vertically fixed on the bracket 1, a through hole 20 is horizontally opened on the support plate 2, the patient's face is located on one side of the support plate 2, and the patient's mouth is located in the through hole 20, the support plate 2 is located on the upper and lower sides of the through hole 20 and has two slide grooves 21 horizontally opened, two pairs of mounting seats 3 are respectively arranged on the two slide grooves 21 and are slidably connected thereto, four open hooks 4 are vertically arranged on the mounting seats 3 in a one-to-one correspondence, and the heads of the open hooks 4 on the upper and lower sides are located at one end close to each other, so as to hook the teeth of the upper and lower jaws of the patient's mouth. Its opening, multiple suction cups 5 are fixed on the inner walls of the upper and lower sides of the through hole 20 at equal intervals, the suction cups 5 are connected with the external negative pressure element through pipes, and when the patient opens his mouth, the suction cups 5 abut against the upper lip and lower lip of the mouth to adsorb and fix the upper lip or lower lip of the patient's mouth. When the impression tray is placed in the patient's mouth, the two mounting seats 3 on one of the slide grooves 21 are pulled away from each other, and the opening hook 4 is separated from the teeth of the upper or lower jaw of the patient's mouth. When the teeth of the upper or lower jaw of the patient approach the impression tray for impression taking, the teeth of the upper jaw are separated from the upper lip or the teeth of the lower jaw are separated from the lower lip.

[0024] In this embodiment, the bracket 1 is used in conjunction with the through hole 20 on the support plate 2. The patient is in a standing or sitting position, with the patient's face abutting against one side of the support plate 2, and the patient's mouth is located in the through hole 20. The patient opens his mouth and uses the opening hook 4 to hook the teeth of the upper and lower jaws respectively, actively assisting the patient to open his mouth. When the demolding tray is placed in the patient's mouth, the teeth of the upper and lower jaws are prevented from scraping the molding material on the molding tray. While assisting the patient to open his mouth, the upper and lower lips of the patient's mouth are respectively abutted against the suction cups 5 on the inner walls of the upper and lower sides of the through hole, and the suction cups 5 are used in conjunction with the external negative pressure element to provide a negative pressure relief for the mouth. The upper and lower lips are adsorbed and fixed. When it is necessary to take an impression of the maxillary or mandibular teeth, the two opening hooks hung on the corresponding teeth are moved away from each other. When the opening hooks are detached from the maxillary or mandibular teeth, the maxillary or mandibular teeth approach and squeeze the impression material on the impression tray, which automatically separates the teeth to be impressioned and the corresponding gums from the upper lip or lower lip, allowing the impression material to fully fill every tiny groove or gully of the teeth and gums, thereby improving the accuracy of oral implant impression taking, achieving precise matching of the manufactured restoration with the patient's oral structure, and ensuring the effectiveness of oral implant treatment.

[0025] As a further optimization scheme, in the present embodiment, two arc plates 6 are provided in the through hole 20, the opening directions of the two arc plates 6 are vertical and opposite to each other, the center line of the arc plate 6 is parallel to the center line of the through hole 20, the arc plate 6 is located between the mounting seat 3 and the head of the opening hook 4, the arc plate 6 is connected to the support plate 2, and the suction cup 5 is fixed at equal intervals on the side where the two arc plates 6 are close to each other.

[0026] In this embodiment, two arc plates 6 are arranged in the through hole 20, and the suction cups 5 are fixed on the arc plates 6 at equal intervals, so that when the opening hook 4 assists the patient's upper and lower jaws to open, the arc plates 6 are used to enable the suction cups 5 to fit with the upper and lower lips, thereby improving the stability of the adsorption and fixation of the upper and lower lips of the patient's mouth, so that when taking the mold, the teeth and gums can be stably separated from the corresponding lips, further improving the convenience of taking the mold.

[0027] Reference Figure 4 , Figure 4 AA is a cross-sectional view of the mold taking auxiliary device of this embodiment, as shown in Figure 4 As shown as a further optimization scheme, in this embodiment, a first connecting rod 51 is vertically fixed in the middle of the two arc plates 6 away from the side of the head of the opening hook 4, and the end of the first connecting rod 51 close to the mounting seat 3 passes through the support plate 2. The first connecting rod 51 is slidingly connected to the support plate 2 along its length direction, and a first elastic member 52 is connected between the end of the first connecting rod 51 away from the arc plate 6 and the support plate 2 to drive the two arc plates 6 to move in a direction away from each other.

[0028] In this embodiment, the first connecting rod 51 and the first elastic member 52 can be used to drive the two arc plates 6 to move away from each other. After the suction cup 5 is adsorbed and fixed to the upper and lower lips of the patient's mouth, it can actively drive the upper and lower lips to separate from the teeth and gums of the upper and lower jaws, and can cooperate with the action of the patient's teeth approaching the molding material for molding, so as to further separate the upper lip or lower lip from the corresponding teeth and gums, and improve the effect of the molding material filling each small groove or gully of the teeth and gums. At the same time, before performing the molding operation, it is also convenient for the operator to observe the teeth and gums on the outside of the upper and lower jaws of the patient's mouth, thereby further improving the effect of oral implant molding.

[0029] As a further optimization scheme, in this embodiment, a second connecting rod 31 is passed through the mounting seat 3, and the second connecting rod 31 is parallel to the first connecting rod 51. The second connecting rod 31 is slidingly connected to the mounting seat 3 along its length direction. One end of the second connecting rod 31 is fixedly connected to the opening hook 4, and a second elastic member 32 is connected between the other end and the mounting seat 3 to drive the opening hooks 4 on the upper and lower sides to move away from each other.

[0030] In this embodiment, the second connecting rod 31 and the second elastic member 32 are used together to drive the opening hooks 4 on the lower sides to move away from each other. When assisting the patient's mouth to open, the angle of the patient's mouth opening can be increased as much as possible, making it convenient to place the mold tray and the mold material into the oral cavity. At the same time, when assisting the opening, the upper and lower lips of the patient's mouth can be made to fit tightly with the suction cup 5 as much as possible, thereby improving the adsorption and fixing effect of the upper and lower lips.

[0031] Reference Figure 1 , Figure 1 FIG. 1 is a top view of the mold taking auxiliary device of this embodiment, as shown in FIG. Figure 1 As shown, as a further optimization scheme, in this embodiment, a V-shaped limit plate 53 is horizontally provided at one end of the first connecting rod 51 away from the opening hook 4, the middle part of the V-shaped limit plate 53 is fixedly connected to the first connecting rod 51, and the end of the second connecting rod 31 away from the opening hook 4 is respectively abutted against the lower side of the V-shaped limit plate 53.

[0032] In this embodiment, a V-shaped limit plate 53 is provided on the first connecting rod 51, and the lower side of the V-shaped limit plate 53 is abutted against the second connecting rod 31, so that the V-shaped limit plate 53 can be used to simultaneously drive the first connecting rod 51, the second connecting rod 31, the arc plate 6, and the opening hook 4 to move toward the middle of the through hole 20. When the opening hook 4 hooks the patient's upper and lower teeth, the suction cup 5 also uses the external negative pressure element to adsorb and fix the upper and lower lips. Then, the first elastic member 52 and the second elastic member 32 drive the upper and lower teeth and lips to open outwards so that the patient's mouth is opened, and the operator puts the mold tray and the mold material into the oral cavity. After entering the interior, the two opening hooks 4 hooked on the teeth of the upper or lower jaw are moved outward, and the second connecting rod 31 also moves outward synchronously. When the opening hooks 4 are separated from the teeth of the upper or lower jaw, they will actively hook the corners of the upper or lower lip, further improving the separation effect of the upper or lower lip from the teeth and gums, making it convenient to use the molding material on the molding tray to mold the teeth and gums of the upper or lower jaw. When the teeth of the upper or lower jaw and the molding material are squeezed into an impression, the two opening hooks 4 continue to move outward until they are separated from the upper or lower lip of the mouth, so that the teeth and gums close to the corners of the mouth can also be separated from the teeth and gums.

[0033] As a further optimization scheme, in this embodiment, the second connecting rod 31 is slidably connected to the mounting seat 3 along its circumference, the longitudinal section of the opening hook 4 is L-shaped, the vertical end of the opening hook 4 is fixedly connected to the second connecting rod 31, and its horizontal section abuts against the teeth of the patient's upper and lower jaws.

[0034] In this embodiment, on the basis of the second connecting rod 31 being slidingly connected with the mounting seat 3 along its length direction, the second connecting rod 31 is rotatably connected with the mounting seat 3, so that when the opening hook 4 is driven to move outward, when the opening hook 4 hooks the upper lip or lower lip of the patient's mouth corner, the opening hook 4 continues to be driven to move outward, and the second connecting rod 31 is used to rotate around its circumference, so that the opening hook 4 is smoothly separated from the upper lip or lower lip of the patient's mouth corner, thereby further improving the ease of use.

[0035] In addition, in this embodiment, the second connecting rod 31 is rotatably connected to the mounting base 3. When the opening hook 4 hooks the patient's upper or lower teeth, the angle of the horizontal section of the opening hook 4 can be adjusted according to the patient's oral condition. The best position of the horizontal section of the opening hook 4 on the same side is in an eight-shape to ensure the stability of the hooking of the upper and lower teeth.

[0036] In this embodiment, when the second connecting rod 31 is rotatably connected to the mounting seat 3, the second elastic member 32 is a spring, which is sleeved on the second connecting rod 31. One end of the spring is connected to the V-shaped limit plate 53. A thrust roller bearing is coaxially sleeved on the second connecting rod 31 and is located on the side of the mounting seat 3 close to the V-shaped limit plate 53. The other end of the spring is connected to the thrust roller bearing, so that when the second connecting rod 31 rotates on the mounting seat 3, the second elastic member 32 always maintains traction on the second connecting rod 31, and at the same time avoids the second elastic member 32 hindering the rotation of the second connecting rod 31.

[0037] As a further optimization solution, in this embodiment, the outer diameter of the horizontal section of the open hook 4 gradually increases from its head to its tail.

[0038] In this embodiment, the outer diameter of the horizontal section of the opening hook 4 gradually increases from the head to the tail, so that the thickness of the horizontal section of the opening hook 4 that contacts the teeth is smaller, which not only makes it convenient to hook the teeth with the opening hook 4, but also prevents the opening hook from scraping the molding material on the molding tray when the molding tray is placed in the oral cavity, thereby further improving the convenience of molding.

[0039] Reference Figure 3 , Figure 3 : is a side view of the mold taking auxiliary device of this embodiment, as shown in Figure 3 As shown, as a further optimization scheme, in this embodiment, the thickness of the support plate 2 gradually decreases from the middle of the slide groove 21 to both ends, and two multi-stage elastic contraction rods 22 are horizontally arranged in the slide groove 21, and their center lines are parallel to the center line of the through hole 20. The multi-stage elastic contraction rod 22 is slidably connected to the support plate 2 along the length direction of the slide groove 21, and one end of the multi-stage elastic contraction rod 22 is fixedly connected to the mounting seat 3, and the mounting seat 3 is abutted against the support plate 2 on the side close to the multi-stage elastic contraction rod 22.

[0040] In this embodiment, the thickness of the support plate 2 gradually decreases from the middle of the slide groove 21 to both ends, which can improve the fit between the support plate 2 and the patient's face, improve the opening hook 4 to hook the upper and lower teeth and the suction cup 5 to fix the upper and lower lips, and at the same time, the multi-stage elastic contraction rod 22 is used to make the opening hook 4 automatically contract when moving outward, so that after the opening hook 4 is separated from the teeth, it can smoothly hook the upper lip or lower lip at the corner of the mouth, further improving the ease of use.

[0042] In this embodiment, the bidirectional screw 23 in the slide groove 21 and the rotating power element 24 on the support plate 2 are used together to drive the multi-stage elastic contraction rod 22, the mounting seat 3, the second connecting rod 31 and the opening hook 4 on the same slide groove 21 to move, thereby further improving the convenience of use.
