Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a dental implant auxiliary tray for oral restoration. Background Technology

[0002] In dental implant treatment, accurately obtaining a patient's oral model is a crucial step, directly affecting the formulation of subsequent implant plans and the restorative outcome. Traditional implant trays have fixed dimensions, making it difficult to accommodate the differences in oral size and shape among different patients. Some patients have small oral cavity or limited mouth opening, making it difficult to place the tray smoothly. Doctors often need to trim the tray on-site, which is cumbersome and prone to damage, affecting its integrity and impression accuracy, resulting in incomplete or inaccurate impressions. Therefore, we propose a dental implant tray for dental restoration. Utility Model Content

[0003] The purpose of this invention is to provide an implant support tray for dental restoration, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a dental implant auxiliary tray for oral restoration, comprising a first tray and a second tray, wherein an upper support groove is formed on the top of the first tray and the second tray, and a lower support groove is formed on the bottom of the first tray and the second tray, wherein a fixing rod is fixedly connected to the inner side of the first tray and the second tray respectively, and a rotating shaft is rotatably connected to the fixing rod, wherein a first handle is fixedly connected to one end of the first tray, and a second handle is fixedly connected to one end of the second tray, and a snap-fit ​​component is provided between the first handle and the second handle.

[0005] The first and second trays each have a tray plate in the middle. The tray plate is a quarter-elliptical ring with the same curvature as the alveolar bone in the oral cavity. The outer side of the tray plate is fixedly connected to a rim.

[0006] The pallet has a positioning hole on its surface, a baffle in the middle of the positioning hole, and a connecting rod fixedly connected between the positioning hole and the baffle.

[0007] The positioning holes are multiple in number and their distribution distance is equal to the distance between the alveolar bone in the oral cavity.

[0008] The snap-fit ​​component includes a snap-fit ​​connector fixedly connected to the first grip, and a snap-fit ​​groove is provided at the snap-fit ​​connector on the second grip.

[0009] The snap-fit ​​groove has a guide slope on the side near the first grip.

[0010] The upper and lower support grooves can be filled with printing molds, which are used to imprint tooth marks.

[0011] This utility model has at least the following beneficial effects:

[0012] In use, this utility model features a positioning hole with a baffle on the tray. When a dental implant transfer rod is present in the oral cavity, the baffle can be opened to avoid it without affecting the overall structure of the tray. The first and second trays are connected by a rotating shaft, allowing for flexible adjustment of the opening degree according to the size of the patient's oral cavity. For patients with small mouths or limited mouth opening, the shape of the tray can be adjusted before use to ensure smooth placement in the oral cavity, avoiding difficulties in taking impressions due to tray size issues. This improves the versatility of the tray and the comfort of the patient. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] Please see Figures 1 to 4This utility model provides a technical solution: a dental implant auxiliary tray for oral restoration, including a first tray 1 and a second tray 2. The outer sides of the first tray 1 and the second tray 2 are fixedly connected to a side circumference 12. The first tray 1 and the second tray 2 have an upper support groove 3 on the top and a lower support groove 4 on the bottom. The inner sides of the first tray 1 and the second tray 2 are respectively fixedly connected to a fixing rod 5. The fixing rod 5 is rotatably connected to a rotating shaft 6. The first tray 1 has a first handle 7 fixedly connected to one end and the second tray 2 has a second handle 8 fixedly connected to one end. A snap-fit ​​member 9 is provided between the first handle 7 and the second handle 8.

[0021] The first tray 1 and the second tray 2 are rotatably connected to the rotating shaft 6 via a fixing rod 5. They are also equipped with a first handle 7 and a second handle 8. When preparing to place the tray into the mouth of a patient with a small mouth, the doctor holds the two handles and opens them outward. At this time, the fixing rod 5 rotates around the rotating shaft 6, causing the ends of the first tray 1 and the second tray 2 to converge inward, changing the overall shape of the tray and reducing its lateral size. This makes it easier to place the tray into the mouth and allows the doctor to easily adjust the tray according to the actual size and shape of the patient's mouth, thus improving the tray's adaptability.

[0022] The tray 11 is a quarter-elliptical ring with the same curvature as the alveolar bone. After the tray is placed into the patient's mouth, the doctor brings the two handles together to reset the first tray 1 and the second tray 2. During the resetting process, the tray 11 can naturally align with the patient's alveolar bone. At the same time, the distribution distance of the positioning holes 111 is equal to the distance of the alveolar bone, which further assists in the precise positioning of the tray and ensures that the tray fits tightly with the teeth, alveolar bone and other structures in the mouth.

[0023] A snap-fit ​​element 9 is provided between the first grip 7 and the second grip 8. The snap-fit ​​element 9 includes a snap-fit ​​connector 91 fixedly connected to the first grip 7 and a snap-fit ​​groove 92 opened on the second grip 8. A guide slope 93 is opened on the side of the snap-fit ​​groove 92 near the first grip 7. When the two grips are brought together, the snap-fit ​​connector 91 slides into the snap-fit ​​groove 92 along the guide slope 93 to complete the fixation. The guide slope 93 plays a guiding role, which makes it easy for the snap-fit ​​connector 91 to accurately enter the snap-fit ​​groove 92. After the snap-fit ​​is completed, it can enhance the stability of the snap-fit ​​and prevent the tray from shifting due to the patient's oral movements during the impression taking process.

[0024] The working principle of this utility model is as follows: Medical staff fill the impression material into the upper groove 3 or lower groove 4 according to the need for impression taking. When preparing to place the tray into the mouth of a patient with a small mouth, the doctor holds the two handles and opens them outward. At this time, the fixing rod 5 rotates around the rotating shaft 6, causing the ends of the first tray 1 and the second tray 2 to converge inward, changing the overall shape of the tray and reducing the lateral size of the tray, making it easier to be placed into the mouth. After the tray is placed into the patient's mouth, the doctor brings the two handles together, so that the first tray 1 and the second tray 2 are reset, and the tray 11 can be naturally aligned with the patient's alveolar bone. When the two handles converge, the snap-fit ​​connector 91 slides into the snap-fit ​​groove 92 along the guide slope 93 to complete the fixation, enhance the stability of the snap-fit, and prevent the tray from shifting due to the patient's oral movements during the impression taking process. The guide slope 93 plays a guiding role, making it easy for the snap-fit ​​connector 91 to accurately enter the snap-fit ​​groove 92, ensuring that the impression material solidifies in a stable environment and obtains an accurate oral impression.

[0025] Example 2

[0026] Please see Figure 4 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the surface of the tray 11 is provided with positioning holes 111, and a baffle 112 is provided in the middle of the positioning hole 111. A connecting rod 113 is fixedly connected between the positioning hole 111 and the baffle 112. There are multiple positioning holes 111, and the distribution distance is equal to the distance of the alveolar bone in the oral cavity. When there is a dental implant transfer rod in the patient's oral cavity, the tray needs to be drilled. The connecting rod 113 is cut with scissors, and the baffle 112 can be opened to make the positioning hole 111 pass through. During the impression taking process, the dental implant transfer rod in the oral cavity can be avoided, ensuring that the tray can fit the oral cavity smoothly. At the same time, it ensures that the impression material can accurately cover the teeth and surrounding tissues to obtain a complete oral model.
