The handle 2 is arranged on the arc top of the tray body 1. The tray body 1 includes a bottom plate 11, and is provided on the inner and outer sides of the bottom plate 11. The inner side wall 12 and the outer side wall 13 of the edge, the radian of the inner side wall 12 and the outer side wall 13 match the radian of the corresponding edge of the bottom plate 11, and the inner side wall 12 and the outer side wall 13 and the bottom plate 11 form a groove whose bottom is narrower than the opening, A sliding bar 14 extending inside the bottom plate 11 is provided at the contact point between the inner side wall 12 and the edge of the bottom plate 11 .

Embodiment 2

[0023] Example 2: as figure 2 As shown, the adjustable oral impression tray provided in this embodiment includes a tray body 1 and a handle 2. The handle 2 is arranged on the arc top of the tray body 1. The tray body 1 includes a bottom plate 11, and is provided on the inner and outer sides of the bottom plate 11. The inner side wall 12 and the outer side wall 13 of the edge, the radian of the inner side wall 12 and the outer side wall 13 match the radian of the corresponding edge of the bottom plate 11, and the inner side wall 12 and the outer side wall 13 and the bottom plate 11 form a groove whose bottom is narrower than the opening, A slide bar 14 extending inside the bottom plate 11 is provided at the contact between the outer side wall 13 and the edge of the bottom plate 11 .

Embodiment 3

[0024] Embodiment 3: Different from the above-mentioned Embodiment 1 and Embodiment 2, both the inner side wall 12 and the outer side wall 13 are provided with slide bars 14, and correspondingly, the bottom plate 11 is provided with a corresponding slide way inside, so that the range that can be adjusted is wider. The most important thing is that the adjusted impression tray can better fit the shape of the patient's teeth by adjusting the inner side wall 12 and the outer side wall 13 together, so that the restoration of the teeth is more accurate.

[0025] As a preferred embodiment, in the above-mentioned embodiment, the opposite side edges of the slide bar 14 are provided with position locking blocks 15 , and correspondingly, the slideway is provided with a locking groove matching with the position locking blocks 15 .

[0026] As a preferred embodiment, in the above embodiment, a Z-shaped pressing arm 3 is provided on the back of the groove of the tray body 1 , and the pressin...
