Upper and lower partition bracket for oral radiotherapy and manufacturing method thereof

Abstract

The invention disclosed a separate stent and its production method for oral radiotherapy.The oral radiotherapy of the present invention is used up and down stent, which contains the bracket body. The bracket body is an empty shell, and its external shape is in line with the internal shape of the oral cavity when the human opening.The surface shells and lower surface shells are provided with upper tooth pressure traces and lower teeth column pressure slots; the rear of the bracket body is supporting the tongue pressing part, and the upper surface of the supporting tongue is the support.The lower surface of the tongue part is the bracket tongue surface; the fixed part and the supporting tongue part are connected by breathable channels.The oral stent of the present invention is suitable for the radiotherapy of oral and maxillofacial tumor, which can stabilize and effectively reduce the dosage of the organs, thereby reducing the oral mucosal damage and taste damage in the treatment of oral and maxillofacial tumor, improve the compliance of patients receiving radiotherapyAnd the quality of survival.

Description

technical field [0001] The invention belongs to the technical field of radiation therapy for head and neck tumors, and in particular relates to an upper and lower partition type oral bracket used in the radiotherapy process of oral and maxillofacial tumors and a manufacturing method thereof. Background technique [0002] Radiation therapy or radiotherapy-based comprehensive therapy is the basic principle for the treatment of head and neck tumors in today's medical field. More than 70% of head and neck malignant tumors require the intervention of radiotherapy in the course of their treatment.
