[0029] Please see Figure 1-4 This utility model provides a technical solution:

[0030] A disposable oral impression includes a mandibular base impression frame 1. The mandibular base impression frame 1 has five through mounting and fixing holes 2 on both the front and rear of its outer surface. A flexible tongue-tethered silicone block 3 is fixedly connected to the lower inner wall of the mandibular base impression frame 1. An impression mounting groove 4 is formed between the lower inner wall of the mandibular base impression frame 1 and the flexible tongue-tethered silicone block 3. Several through permeable holes 8 are opened on the lower inner wall of the impression mounting groove 4. A mandibular buffer layer structure 5 is movably engaged in the impression mounting groove 4. A connecting block 6 is fixedly connected to the right side of the outer surface of the mandibular base impression frame 1. A hand handle 7 is fixedly connected to the end of the connecting block 6 away from the mandibular base impression frame 1.

[0031] In this embodiment, the lower tooth buffer layer structure 5 includes a lower tooth elastic frame 51. The upper end of the lower tooth elastic frame 51 has a lower tooth mold groove 52. The lower inner wall of the lower tooth mold groove 52 has several through holes 53. Five elastic rubber pads 54 are fixedly connected to the front and rear parts of the outer surface of the lower tooth elastic frame 51. The ten elastic rubber pads 54 correspond one-to-one with the positions and sizes of the ten mounting and fixing holes 2. The lower tooth elastic frame 51 is movably inserted into the lower tooth base impression frame 1 through the ten elastic rubber pads 54 and the ten mounting and fixing holes 2. The size and area of ​​the lower tooth elastic frame 51 are equal to the size and area of ​​the impression mounting groove 4. The lower tooth elastic frame 51 is located in the impression mounting groove 4. The upper end face of the lower tooth elastic frame 51 is flush with the upper end face of the lower tooth base impression frame 1. The flexible tongue silicone block 3 is located inside the lower tooth elastic frame 51. Several permeation holes 8 are connected to several through holes 53.

[0032] Through the above scheme: the lower tooth base impression frame 1 provides basic support and shape framework for the whole, and its installation and fixing holes 2 are correspondingly inserted with the elastic rubber pads 54 of the lower tooth elastic frame 51, so that the lower tooth buffer layer structure 5 is accurately installed in the impression installation groove 4, and the two are matched in size and flush at the top end, ensuring structural stability and uniform force on the impression. The flexible lingual silicone block 3 is located inside the lower tooth elastic frame 51, conforming to the lingual side of the oral cavity, preventing the impression material from overflowing and improving comfort. During the impression, the impression material is placed in the lower tooth impression groove 52, and the permeation hole 8 is connected to the through hole 53, allowing the material to permeate and diffuse evenly between layers, avoiding uneven distribution caused by local accumulation or poor flow. The lower tooth elastic frame 51 can be appropriately deformed according to the shape of the patient's lower teeth to better conform to the tooth contour, reduce impression deformation and loss of details, thereby effectively solving the problems of general impression trays, improving the accuracy of restoration fabrication, ensuring the reliability of treatment results, and providing a better solution for oral impression taking.

[0033] It should be noted that this utility model is a disposable oral impression. During use, the lower tooth base impression frame 1 serves as the main frame. Its mounting and fixing holes 2 cooperate with the elastic rubber pads 54 of the lower tooth buffer layer structure 5, allowing the lower tooth elastic frame 51 to be precisely inserted into the impression mounting slot 4. Because the two are of equal size and area and their upper surfaces are flush, structural stability and uniform force during impression taking are ensured. The lower tooth elastic frame 51 can adapt to different patients' lower tooth shapes, thus solving the problem of difficult fitting of universal impression trays and reducing impression deformation and loss of detail. To improve the precision of prosthesis fabrication, a flexible lingual silicone block 3 is placed inside the lower tooth elastic frame 51, conforming to the physiological structure of the lingual side of the oral cavity, thereby improving patient comfort and preventing impression material overflow, ensuring impression integrity, and improving the reliability of treatment results. The impression material is placed in the lower tooth impression socket 52. Since several permeation holes 8 and several through holes 53 are connected, the impression material is evenly distributed in the impression area during the impression taking process, which can avoid impression defects caused by uneven distribution. Finally, medical staff operate the entire impression device by holding the handle 7.
