3D printing-based radiotherapy oral cavity stand manufacturing method and device and medium

Abstract

The invention provides a 3D printing-based radiotherapy oral cavity stand manufacturing method. The radiotherapy oral cavity stand manufacturing method comprises the steps of acquiring illness state information, calculating oral cavity supporting structure information, calculating stand fixing structure information, generating tongue positioning structure information, calculating ventilation channel information, generating a personalized oral cavity stand 3D model, generating 3D curved surface data and printing an oral cavity stand. According to the 3D-based radiotherapy oral cavity stand manufacturing method, the obtained personalized stand can achieve a relatively good radiotherapy effect; when a to-be-treated patient uses the personalized oral cavity stand, the personalized oral cavity stand is not prone to move, thus avoiding the problem that the set-up error is too large in the radiotherapy process due to poor position repeatability; and meanwhile, the manufacturing process of the personalized oral cavity stand does not depend on impression occlusion molding of the patient, thus avoiding the problem that the treatment effect is affected due to the fact that the tongue position is difficult to fix to an ideal position in the occlusion process of the patient.

Description

technical field [0001] The invention relates to the field of oral brackets, in particular to a manufacturing method, equipment and medium for a radiotherapy oral bracket based on 3D printing. Background technique [0002] Radiation therapy is widely used in the treatment of malignant tumors of the head and neck. However, various acute and late radiation injuries caused by radiation therapy, such as oral mucositis, xerostomia, and osteoradionecrosis, seriously affect the quality of life of patients. The application of oral stents helps to reduce these injuries and improve the quality of life of patients. At present, most of the oral brackets used in radiation therapy use cork plugs of uniform specifications as oral brackets, which are easy to move and have poor position repeatability, which eventually leads to excessive positioning errors during radiation therapy.
