[0002] In today's medicine, more than 70% of head and neck malignant tumors need the intervention of radiotherapy in the treatment process. However, the function damage of parotid gland, oral mucosa damage and taste damage caused by radiotherapy have seriously affected the quality of life of head and neck cancer patients, and even the follow-up treatment has to be stopped, thereby reducing the local control rate of tumor.

[0003] In the existing technology, cork and the like are often used to push the tongue and oral mucosa away from the target area, but this method mainly has the disadvantages of uncertain tongue pressing effect, poor position repeatability and inability to individualize. Therefore, the use of individualized oral cavity support can effectively push the tongue and oral mucosa of the patient away from the tumor, so as to reduce the irradiation dose and avoid damage to the tongue and oral mucosa in radiotherapy. At present, there are two methods for manufacturing individualized oral cavity support for radiotherapy. One is the method of using impression paste: the impression paste is softened, kneaded into a shape, put into the patient's mouth to bite and shape, washed and shaped under water after being taken out, and CT tomography is performed, then the data are post-processed to obtain the tooth profile, and then the modeling of the oral cavity support is performed.
