Theoverflow type dental impression tray can prevent an impression material from flowing into an oral cavity, the tray and the impression material can be quickly separated, and the overflow type dental impression tray is convenient to clean.

Description

technical field [0001] The invention relates to a tray, in particular to an overflow-draining dental impression tray.

AI Technical Summary

Problems solved by technology

[0004] First: After the tray filled with impression material is put into the mouth, the overflow of the impression material will easily cause nausea and retching of the patient, which not only reduces the comfort, but also affects the quality of the impression due to the movement of the patient; for patients with obvious gag reflex , it is easy to cause the failure of model taking and affect the treatment

[0005] Second: After the material is cured, the impression material is connected to the tray as a whole. When medical staff take out the cured impression material, they often need to destroy the cured impression material, and the operation is complicated and the work efficiency is low;

[0006] Third: At present, the dental impression trays commonly used by dentists are made of metal materials.
