Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a disposable tooth impression tray. Background Art

[0002] When taking the maxillary model with the current disposable impression tray, the index finger and ring finger need to fix the model in the mouth. If the model is pressed hard, it is easy to be demolded. In addition, the edge of the existing disposable tray is not wrapped, so a large amount of impression material may flow into the mouth, causing nausea in the patient and ultimately leading to failure of impression taking.

[0003] For patients with relatively large dental arches, disposable trays cannot meet the needs when taking removable denture models. Doctors use alcohol lamps to soften the maxillary trays and then break them apart before they can be used in clinical practice. However, the trays in this case are prone to deformation in the center and may become scrapped due to deformation. Utility Model Content

[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 1:

[0028] See also Figures 1 to 4 The utility model provides a disposable dental impression tray, comprising a tray body 2, wherein the tray body 2 comprises a side panel 2.1 and a bottom panel 2.2, wherein the bottom panel 2.2 is a U-shaped flat plate, and the side panel 2.1 is a U-shaped ring panel, wherein the side panel 2.1 is fixedly connected to the outer U-shaped edge of the bottom panel 2.2, and a handle 1 is arranged at the center of the outer end surface of the side panel 2.1, and a base 4 is arranged at the lower end surface of the bottom panel 2.2, and the U-shaped bottom panel 2.2 has two symmetrical arm panels, and a base 4 is arranged at the center position of the bottom surface of each arm panel, and the interior of the bottom panel 2.2 is a U-shaped opening, and the bottom panel 2.2 is spliced ​​with a tongue-shaped plate 3 at the U-shaped opening, and the tongue-shaped plate 3 and the side panel 2.1 are both arranged above the bottom panel 2.2, and the non-spliced ​​edges of the tray body 2 and the tongue-shaped plate 3 are provided with retaining edges.

[0029] In this embodiment, the tray body 2 and the tongue-shaped plate 3 are made of a macromolecular polymer material, such as high-density polyethylene, so that the tray body 2 and the tongue-shaped plate 3 have deformation capability.

[0030] A buckle 8 is provided at the bottom of the tongue-shaped plate 3, and a bayonet is provided at the periphery of the U-shaped opening of the bottom plate 2.2. The buckle 8 can be engaged with the bayonet to realize the splicing of the tongue-shaped plate 3 and the bottom plate 2.2. Considering that the spacing of the bayonet will not change evenly after the tray body 2 is deformed, in order to make the splicing easier to achieve, a slit is provided at the bottom of the tongue-shaped plate 3 to enhance the deformation ability of the bottom of the tongue-shaped plate 3. When used specifically, tongue-shaped plates 3 of various sizes are prepared. If the size of the tray body 2 needs to be changed, an alcohol lamp is used to soften the tray body 2 and then it is broken apart to expand the U-shaped opening, and a tongue-shaped plate 3 of suitable size is selected to be installed in the tray body 2. The tongue-shaped plate 3 is a deformable material and can be elastically deformed within a certain range. The slit further enhances the size adaptability range of a single tongue-shaped plate 3.

[0031] Specifically, at least three buckles 8 and bayonet ports are provided. Figure 4 As shown, the tongue-shaped plate 3 is provided with a slit between every two buckles 8, and the slit width is 0.5-2 mm.

[0032] The side plate 2.1, the bottom plate 2.2 and the tongue-shaped plate 3 are all provided with overflow holes for discharging excess material.

[0033] Among them, the side panel 2.1 and the bottom panel 2.2 are made of one piece, and a top guard 5 is arranged at the upper end of the side panel 2.1, and a first front guard 6 is arranged at the two ends of the side panel 2.1 and the two ends of the bottom panel 2.2, and a second front guard 7 is arranged at the front opening end of the tongue-shaped plate 3. After the tongue-shaped plate 3 and the bottom panel 2.2 are assembled, the second front guard 7 does not contact the first front guard 6, and a gap is left, and the gap distance is 0.2-1mm, so as to improve the adaptability of the assembly; the top guard 5, the first front guard 6, and the second front guard 7 are used to reduce the loss of the impression material flowing into the patient's mouth, so as to avoid nausea of ​​the patient and the failure of the molding, and the guard can enhance the bonding force between the impression material and the tray body 2, so as to reduce the rate of the molding material coming out.

[0034] Furthermore, the top rib 5, the first front rib 6 and the second front rib 7 are configured as curled edges to further improve the stopping ability.

[0035] Among them, the base 4 is used to provide a force point for the fingers when fixing the model in the oral cavity, so as to avoid stress concentration caused by directly pressing the base plate 2.2 and accidental demolding. Specifically, the base 4 is integrally formed with the base plate 2.2, and the base 4 is provided with an overflow hole and anti-slip grooves to facilitate the doctor's operation.

[0036] Embodiment 2:

[0037] Based on Example 1, this embodiment provides a method for using a disposable tooth impression tray, comprising the following steps:

[0038] S1. Prepare a tray body 2 and three different types of tongue-shaped plates 3. Confirm the shape of the tray body 2 according to the patient's dental arch, adjust the shape of the tray body 2 by heating with an alcohol lamp, select a suitable tongue-shaped plate 3 for splicing, set the slit so that the tongue-shaped plate 3 has a larger self-adjustment range, and assemble the disposable tray;

[0039] S2. Place the impression material into a disposable tray;

[0040] S3. Place the disposable tray into the patient's oral cavity to make an upper jaw impression. Hold the base 4 with fingers to stabilize the disposable tray. Take the impression after the impression material solidifies. The base 4 makes the force on the bottom plate 2.2 uniform. The retaining edge improves the bonding force between the impression material and the disposable tray, thereby reducing the rate of impression material falling out during impression taking.
