Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of dental model tray, specifically relates to a dental model tray. BACKGROUND

[0002] The dental model tray is a tool for making dental models, which are models of teeth that can be used to record the shape and size of teeth in order to make appropriate crowns, bridges or dentures. Dental model trays are usually made of plastic or metal materials and can be selected according to different needs. When making dental models, doctors or dental technicians will apply special materials such as silicone rubber or alginate to the dental model tray, then place the tray in the patient's mouth, and let the patient bite the model. After the material solidifies, the tray is removed, and the patient's tooth model is obtained.

[0003] A new dental model tray for oral medicine (authorized publication number CN 213910622U) is disclosed in a Chinese patent. This patent technology can first place the dental model inside the lower tray, and the dental model can be clamped by the dental model clamping mechanism to prevent the dental model from being stored insecurely. Then, the upper chuck is clamped into the lower tray to store the dental model. The rubber block has a certain elasticity to protect the dental model and avoid damage to the surface of the dental model caused by excessive clamping force of the dental model clamping mechanism. The opening on the upper chuck can avoid the problem of the upper chuck being difficult to clamp into the lower tray due to the presence of the dental model clamping mechanism. However, the existing dental model tray is usually of a single size and cannot be adjusted to fit the user's oral cavity, resulting in poor adaptability of the dental model tray. In addition, the separation method usually uses hands to pull out the shaped dental film, which can easily damage the shaped dental film, causing deformation and fracture of the film material and plaster, resulting in the need for rework. Moreover, the tray is usually single, so the upper and lower jaw films after molding need to be classified, and the classification of multiple shaped dental films is very inconvenient.
