[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment: A novel adjustable stainless steel impression tray, such as Figure 1 - Figure 4 As shown, it includes a maxillary tray 1.

[0028] The invention comprises an upper jaw tray 1 and a lower jaw tray 2, wherein the inner and outer edges of the upper jaw tray 1 and the lower jaw tray 2 are both provided with slidably adjustable frame components, and the upper jaw tray 1, the lower jaw tray 2 and the frame components on the upper jaw tray 1 and the lower jaw tray 2 are all made of stainless steel, wherein the upper jaw tray 1 is an arc-shaped structure, and the upper frame component of the upper jaw tray 1 comprises a first protective inner frame 103 and a first protective outer frame 101 on the inner and outer sides of the upper jaw tray 1, and the top of the first protective outer frame 101 is provided with a plurality of groups of open point grooves 102, and the first protective inner frame 103 ... An open point groove 2 104 is provided on the top of the mandibular tray 2, the mandibular tray 2 is a fan-shaped structure, and is provided with a mandibular tray 2 which is engaged with the first protective inner frame 103 up and down, and the frame assembly on the other side of the mandibular tray 2 includes a second protective outer frame 201, and at least three groups of open point grooves 3 202 are provided on the second protective outer frame 201, the maxillary tray 1 and the mandibular tray 2 are engaged up and down, and the second protective outer frame 201 wraps the outer side of the first protective outer frame 101, and a tongue baffle 3 is installed on the mandibular tray 2, and the tongue baffle 3 can shield the tongue part.

[0029] The present technical solution is essentially different, and adopts a unique open frame design. The open point groove 102, the open point groove 104 and the second protective outer frame 201 are selected at the stress concentration point, so that the size and shape of the tray can be adjusted. The number of the open point groove 102 and the open point groove 104 in the present technical solution is at least between 2 and 12, and is opened according to actual needs.

[0030] Furthermore, the upper and lower jaw trays 1 and 2 are provided with heat dissipation holes 105 for circulating air or solution. By providing the heat dissipation holes 105 on the upper and lower jaw trays 1 and 2, air and aqueous solutions can be circulated in the upper and lower jaw trays 1 and 2 placed on the teeth, which not only improves the comfort of the patients but also facilitates the cleaning afterwards.

[0031] Furthermore, the width of both ends of the first protective outer frame 101 gradually narrows.

[0032] Furthermore, the back of the upper jaw tray 1 and the lower jaw tray 2 are both provided with a gripping assembly, which includes a gripping body 4 and a reserved hole 401 on the gripping body 4. The three-dimensional gripping assembly and the three-dimensional gripping body 4 increase the stability of the mold. Compared with the traditional flat handle, the new design greatly improves the work efficiency of the dentist and improves the accuracy of the mold.

[0033] Innovation

[0034] 1. Adjustability, which is the essential difference from the traditional stainless steel plate.

[0035] The steel tray has a complete structure, good rigidity, high temperature resistance, and will not fall off the mold. However, its only disadvantage is that it adopts a fixed or one-piece structure, and its fixation cannot be adjusted. It cannot adapt to the tooth shape of everyone, because the height of people's dental arches is not exactly the same. Therefore, the clinical application of traditional stainless steel trays is greatly limited. The new adjustable stainless steel tray adopts an open structure, cleverly utilizing the toughness of the metal itself, and realizing the adjustability of the tray shape, which makes up for the only major defect of the traditional stainless steel tray.

[0036] Second, sufficient rigidity. The open structure of the pallet has a particular choice of opening point (cutting point). Maintaining sufficient rigidity is also one of the factors for the accuracy of the pallet. Adjustability and rigidity are a pair of contradictions. The better the adjustability, the worse the rigidity, and the better the rigidity, the worse the adjustability. Therefore, the position of the opening point (cutting point) is very important. After repeated tests, the choice of cutting point ( Figure 1 - Figure 3 shown).

[0037] To sum up, the inherent high temperature resistance of stainless steel can withstand high temperature and high pressure consumption requirements and save costs, which are not available in plastic nets and plastic trays (disposable). In clinical applications, the fixed stainless steel material is not easy to break, and the modified open paper structure makes it adjustable while maintaining sufficient rigidity, open adjustment, and high temperature resistance.

[0038] The working principle of this utility model:

[0039] The advantages of this technical solution are:

[0040] 1. Simplify the dentist's preoperative preparation and improve work efficiency.

[0041] 2. Significantly improve the dentist's impression taking accuracy.

[0042] 3. It can be reused efficiently, replacing traditional plastic-steel and plastic-aluminum alloy pallets, reducing waste of resources.

[0043] Fourth, the use of a unique open frame structure solves the problem that the shape and size of traditional stainless steel impression trays cannot be adjusted. It can adapt to the dental arch shapes of all different groups of people and greatly improves the clinical efficiency of dentists in taking impressions.

[0044] 5. The use of a three-dimensional handle solves the problem of poor grip of the flat handle of the traditional stainless steel tray, enhances the stability of the tray's inlet and outlet cavities and the solidification process, and improves the accuracy of mold taking.

[0045] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
