Description

Technical Field

[0001] The utility model relates to a dental tray, in particular to a dental tray with a honeycomb groove-shaped tissue surface structure. Background Art

[0002] Dental trays are a key tool for taking initial impressions in prosthodontics. Their design and performance directly impact the accuracy of the impression and the effectiveness of subsequent denture restorations. In clinical practice, dental tray design must meet multiple technical requirements: First, it must ensure that the impression material adheres securely to the tray to prevent peeling during impression removal; second, it must apply uniform pressure to edentulous areas requiring pressure to achieve a high-quality initial impression. However, existing dental tray designs still have numerous shortcomings in these areas.

[0003] While traditional solid-bottom trays (such as those described in CN222383395U) can be used to apply pressure to the freed defect area, their simple surface structure lacks an effective bonding mechanism with the impression material. This results in the impression material easily peeling off the tray surface during the impression removal process, especially when the impression material is highly fluid.

[0004] Perforated tissue trays (such as those described in CN222383395U) enhance the mechanical bond between the impression material and the tray by providing multiple through-holes on the tray surface. However, this design has significant drawbacks in practical applications. While the through-hole design improves the adhesion of the impression material, it also relieves some of the pressure required for impression removal, resulting in an inability to achieve an ideal impression in edentulous areas where pressure is required.

[0005] To address the shortcomings of these two tray types, clinical practice often involves applying adhesive to non-porous trays to improve the bond between the impression material and the tray. However, this approach presents numerous challenges. First, applying the adhesive requires additional time and steps, increasing the complexity of clinical work. Second, ensuring uniform adhesive application is difficult, especially around the edges and corners of the tray, where uneven application can easily lead to detachment of the impression material. Utility Model Content

[0006] The purpose of the present utility model is to overcome the defects of the above-mentioned prior art and provide a dental tray with a honeycomb groove-shaped tissue surface structure. Through the design of densely arranged polygonal groove array units and connecting holes, it can not only achieve mechanical embedding of the impression material, but also effectively prevent the impression material from peeling off while maintaining the impression pressure.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] The utility model provides a dental tray with a honeycomb groove-shaped tissue surface structure, which is used for making a preliminary impression of an edentulous jaw. The tray comprises a tray body and a connecting handle provided on one side of the tray body. The tray body is a tissue surface for placing an impression material. The tissue surface of the tray body is provided with a plurality of densely arranged polygonal groove array units, and the polygonal groove array units are connected by a shared side wall to form a honeycomb network structure.

[0009] A connecting hole is opened on the connected wall surface of adjacent polygonal groove array units. The aperture of the connecting hole is smaller than the inner diameter of the honeycomb surface of the groove unit, so that the mold material can pass through the connecting hole to achieve mechanical interlocking of the mold material and the tray body.

[0010] Furthermore, the polygonal groove array unit is a hexagonal groove unit, and its side length is 0.5-1 mm.

[0011] Furthermore, the aperture of the communication hole is 0.2-0.4 mm smaller than the height of the shared side wall of the polygonal groove array unit.

[0012] Furthermore, the thickness of the shared side wall of the polygonal groove array unit is 0.05-0.15 mm.

[0013] Furthermore, the groove depth of the polygonal groove array unit is 0.1-0.3 mm.

[0014] Furthermore, the communication holes are circular through holes, and the communication holes are symmetrically distributed along the central axis of the shared side wall of the polygonal groove array unit.

[0015] Furthermore, at the edge of the tray body, the polygonal groove array unit is an incomplete hexagonal groove structure that matches the edge of the tray body.

[0016] Furthermore, a circle of flanges is provided at the edge of the tray body, and the height of the flanges is greater than the height of the shared side walls of the polygonal groove array units.

[0017] Furthermore, a warping portion is provided on the edge of the tray body, forming a U-shaped closed side of the tray body, and the connecting handle is connected to the U-shaped closed side.

[0018] Furthermore, the tray body is a 3D printed one-piece molding structure.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1) The tray body of the present invention adopts a honeycomb structure, which significantly improves the bonding force between the impression material and the tray through densely arranged polygonal groove array units and connecting holes. Specifically, the polygonal groove array units are connected by shared side walls to form a honeycomb mesh structure. This structure not only increases the contact area between the tray and the impression material, but also realizes the mechanical interlocking of the impression material through the connecting holes. The aperture of the connecting hole is smaller than the inner diameter of the honeycomb surface of the groove unit, so that the impression material can pass through the connecting hole and fill between the groove units, forming a tight mechanical interlocking relationship, which effectively prevents the impression material from peeling off due to pressure changes or excessive fluidity during the demolding process, while maintaining a uniform distribution of the demolding pressure, avoiding the reduction of the impression accuracy due to pressure release.

[0021] 2) In addition, the honeycomb structure design also has good material dispersion performance, which can evenly distribute the impression material and ensure that all parts of the impression can obtain sufficient material filling, thereby further improving the integrity and stability of the impression.

[0024] The following is a detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments. Any features such as preparation methods, materials, structures or composition ratios not explicitly described in this technical solution are considered to be common technical features disclosed in the prior art.

[0025] Example 1

[0026] The present embodiment provides a dental tray with a honeycomb groove-shaped tissue surface structure, which is used to make a preliminary impression of an edentulous jaw, comprising a tray main body 1 and a connecting handle 2 arranged on one side of the tray main body 1. The tray main body 1 is a tissue surface for setting an impression material. A plurality of densely arranged polygonal groove array units 11 are provided on the tissue surface of the tray main body 1. The polygonal groove array units 11 are connected by shared side walls to form a honeycomb network structure; connecting holes 12 are provided on the connected wall surfaces of adjacent polygonal groove array units 11. The aperture of the connecting hole 12 is smaller than the inner diameter of the honeycomb surface of the groove unit, so that the impression material can pass through the connecting hole 12 to achieve mechanical interlocking of the connecting hole 12 and the tray main body 1.

[0027] Specifically, the mechanical bond between the tray and the impression material is enhanced by providing a plurality of densely spaced polygonal groove array units 11 on the tissue surface of the tray body 1. These polygonal groove array units 11 are interconnected via shared sidewalls, forming a honeycomb-like network structure. When the impression material is placed on the tray body 1, it naturally flows into the connecting holes 12 formed on the connecting walls of adjacent polygonal groove array units 11. Because the aperture of the connecting holes 12 is smaller than the inner diameter of the honeycomb surface of the groove units, the impression material forms an "anchor" effect within them, achieving a mechanical fit with the tray body 1, enhancing adhesion between the two, and preventing the impression material from peeling off during use.

[0028] In a specific implementation, the polygonal groove array unit 11 is a hexagonal groove unit with a side length of 0.5-1 mm. The aperture of the communication hole 12 is 0.2-0.4 mm smaller than the height of the shared side wall of the polygonal groove array unit 11. The thickness of the shared side wall of the polygonal groove array unit 11 is 0.05-0.15 mm. The groove depth of the polygonal groove array unit 11 is 0.1-0.3 mm.

[0029] Specifically in principle, in the present invention, the polygonal groove array unit 11 adopts a hexagonal design with a side length of 0.5-1mm, because the hexagon can be arranged most densely on the plane, maximize the use of space, form a stable honeycomb mesh structure, and enhance the bonding force between the tray and the impression material. The aperture of the connecting hole 12 is 0.2-0.4mm smaller than the height of the shared side wall, so that after the impression material passes through the connecting hole, it can form an effective anchor in the groove unit to prevent material peeling. The thickness of the shared side wall is 0.05-0.15mm, which not only ensures the structural strength, but also does not hinder the flow of the impression material too much, so that it can be smoothly filled and mechanically interlocked. The groove depth of the hexagonal groove unit is 0.1-0.3mm, which can provide sufficient space for the impression material to flow in to form an interlock, and ensure that the tray body 1 has sufficient thickness to apply the mold pressure, thereby effectively preventing the impression material from peeling while maintaining the mold pressure, and improving the impression quality and stability.

[0030] In a specific implementation, the communication holes 12 are circular through holes, and the communication holes 12 are symmetrically distributed along the central axis of the shared side wall of the polygonal groove array unit 11 .

[0031] In a specific implementation, at the edge of the tray body 1 , the polygonal groove array unit 11 is an incomplete hexagonal groove structure that matches the edge of the tray body 1 .

[0032] In a specific implementation, a flange 14 is provided at the edge of the tray body 1 , and the height of the flange 14 is greater than the height of the shared side wall of the polygonal groove array unit 11 .

[0033] Specifically in principle, in the present invention, the connecting holes 12 are designed as circular through holes and are symmetrically distributed along the central axis of the shared side wall of the polygonal groove array unit 11, so that the impression material can flow evenly into the groove unit, forming a symmetrical mechanical fit, enhancing the bonding force and ensuring structural stability. The polygonal groove array unit 11 at the edge adopts an incomplete hexagonal groove structure that matches the edge of the tray body 1, which not only adapts to the shape of the tray body, but also ensures the mechanical fit of the impression material at the edge, preventing the material from peeling off. At the same time, the height of the flange 14 set at the edge of the tray body 1 is greater than the height of the shared side wall, which can effectively prevent the impression material from overflowing or peeling off at the edge, protect the integrity and fit of the internal honeycomb structure, and ensure the quality of the impression.

[0034] In a specific implementation, a warping portion 13 is provided on the edge of the tray body 1 to form a U-shaped closed side of the tray body 1 , and the connecting handle 2 is connected to the U-shaped closed side.

[0035] In a specific implementation, the tray body 1 is a 3D printed one-piece molding structure.

[0036] The above description of the embodiments is intended to facilitate understanding and use of the utility model by those skilled in the art. Those skilled in the art will readily be able to make various modifications to these embodiments and apply the general principles described herein to other embodiments without requiring inventive effort. Therefore, the utility model is not limited to the above-described embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of this utility model without departing from the scope of this utility model should be within the scope of protection of this utility model.
