[0002] When performing dental implant restoration, the patient's dentition shape is usually used for impression taking. During the impression taking process, an oral impression tray and silicone rubber are required. First, the silicone rubber is filled into the oral impression tray, and then the patient is asked to take impressions of the maxillary and mandibular dentition. After the impression is obtained and the dentition model is obtained by pouring plaster, the silicone rubber is taken out of the oral impression tray. When performing dental implant restoration, the impression material needs to be filled on the impression tray, and then the impression tray is placed in the oral cavity to accurately transfer the position of the implant or abutment. In the existing oral impression tray, the tray is taken out by holding the connecting rod, but during the impression taking, the force on both sides of the tray may be uneven due to improper operation, causing the model to deform and reducing the accuracy of the impression.

[0026] Example

[0027] like Figure 1-3 As shown, the utility model provides an oral cavity impression tray structure, including a first tray 1 and a second tray 2. The first tray 1 is used to wrap the upper dental arch, and a plurality of first overflow holes 101 are provided on the first tray 1. The second tray 2 is used to wrap the lower dental arch, and a plurality of second overflow holes 201 are provided on the second tray 2. The first overflow holes 101 and the second overflow holes 201 are used to overflow excess silicone rubber during the molding process.

[0028] In this embodiment, the first tray 1 and the second tray 2 are detachably connected, and an isolation sheet 14 is provided at the front end of the second tray 2. The isolation sheet 14 is a rectangular plate with a grid sheet in the middle. The isolation sheet 14 is used to prevent the impression material from flowing down and causing suffocation of the patient, thereby improving the installation efficiency of the device. Slide grooves 4 are provided on both sides of the isolation sheet 14, and a connecting rod 5 slidably installed in the slide groove 4 is fixedly installed at the bottom of the front end of the first tray 1.

[0029] Among them, a slider 11 is rotatably installed on one side of the connecting rod 5 close to the isolation piece 14, and the slider 11 is slidably installed in the slide groove 4. A rotating plate 12 is fixedly installed on one side of the slider 11 that passes through the slide groove 4. A screw 13 is provided on the side of the slider 11 close to the connecting rod 5. The connecting rod 5 is provided with a threaded hole adapted to the screw 13. The width of the rotating plate 12 is 1-3 mm smaller than the width of the slide groove 4. The rotating plate 12 is rotated to make the screw 13 on one side of the slider 11 rotate in the slide groove 4, so that the rotating plate 12 is rotated to be parallel to the slide groove 4, and then the rotating plate 12 is directly taken out of the slide groove 4, thereby realizing the disassembly of the first tray 1 and the second tray 2, and improving the convenience of use.

[0030] In addition, the rear ends of the first tray 1 and the second tray 2 are fixedly installed with handles 3, and a reinforcement component is provided in the handle 3. The reinforcement component includes a U-shaped spring piece 6 movably installed in the handle 3, and insertion seats 9 for inserting the two ends of the U-shaped spring piece 6 are fixedly installed on both sides of the handle 3. An arc block 7 is fixedly installed on one end of the handle 3 close to the first tray 1 and the second tray 2, and the top of the U-shaped spring piece 6 is pressed against the inner side of the arc block 7. A limit block 8 is fixedly installed in the handle 3, and the limit block 8 is located on the inner side of the top of the U-shaped spring piece 6. The limit block 8 is used to prevent the U-shaped spring piece 6 from shifting. A circular hole 10 is opened on the handle 3, and the first tray 1 and the second tray 2 are taken out through the handle 3. Under the action of the U-shaped spring piece 6, when one side of the tray is subjected to greater pressure, the U-shaped spring piece 6 will be compressed, thereby reducing the force on this side and transferring part of the pressure to the other side, so that the force on both sides of the tray is uniform, thereby reducing deformation and improving the accuracy of mold taking.

[0031] Working principle: During the working process of the utility model, when the first tray 1 and the second tray 2 need to be disassembled, the rotating plate 12 is rotated to make the screw 13 on one side of the slider 11 rotate in the slide groove 4, so that the rotating plate 12 is rotated to be parallel to the slide groove 4, and then the rotating plate 12 is directly taken out of the slide groove 4, thereby realizing the disassembly of the first tray 1 and the second tray 2, improving the convenience of use, and during use, the isolation sheet 14 provided with a grid sheet in the middle prevents the impression material from flowing down and causing suffocation of the patient, thereby improving the installation performance of the device. After the molding is completed, the staff takes out the first tray 1 and the second tray 2 through the handle 3. During the removal process, under the action of the U-shaped spring sheet 6, when one side of the tray is subjected to greater pressure, the U-shaped spring sheet 6 will be compressed, thereby reducing the force on this side, and transferring part of the pressure to the other side, so that the force on both sides of the tray is uniform, thereby reducing deformation and improving the accuracy of molding.

[0032] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
