Dental stent for making radiotherapy individualized mouth holding device

Abstract

The invention discloses a dental stent for making a radiotherapy individualized mouth holding device. The dental stent comprises supporting columns, an upper dental arch groove, a lower dental arch groove, a tongue pressing plate, a ventilation channel and a handle; the main body of the dental stent is sized and shaped to match an open oral cavity; the supporting columns are disposed at two sidesof the dental stent; the upper dental arch groove and the lower dental arch groove are respectively arranged on and below the supporting columns; the rear end of the lower dental arch groove is provided the tongue pressing plate connected with the lower dental arch groove; the ventilation channel is arranged between the supporting columns at the two sides; and the handle connected with the lower dental arch groove is arranged between the supporting columns at the two sides. With the dental stent of the invention adopted, the lower jaw and upper jaw of a patient can be separated from each otherduring the making of the radiotherapy individualized mouth holding device, so that the mouth of the patient can be kept open. The dental stent can be adopted as a carrier of silicone rubber; the silicone rubber can be placed on the dental stent, so that the impressions of dental tissues such as teeth and a tongue can be made, so that individualization can be realized; and therefore, the making steps of the radiotherapy individualized mouth holding device can be simplified, and fixing precision can be improved.

Description

Technical field [0001] The invention relates to the technical field of medical equipment, in particular to an oral stent used for making individualized oral devices for radiotherapy. Background technique [0002] The radiotherapy mouthpiece is an auxiliary positioning device for the oral cavity for the radiotherapy of head and neck tumors. It can be combined with the head, neck and shoulder thermoforming nets to fix the patient's position to improve the accuracy and repeatability of the upper and lower jaw and tongue. Local tumors fix normal tissues as far away as possible from the target area to reduce the occurrence of adverse reactions such as oral mucositis, dysgeusia, and dry mouth. However, in the current clinical application, most simple radiotherapy mouthpieces such as open mouth bottles, corks, tongue depressors, syringes, etc. are used for maxillofacial radiotherapy. When used, it is difficult to ensure the repeatability and comfort of the upper and lower jaw and tongue...

AI Technical Summary

Problems solved by technology

However, in current clinical applications, relatively simple radiotherapy mouthpieces such as mouth-opening bottles, corks, spatulas, and syringes are mostly used for radiotherapy positioning of the maxillofacial region. When using them, it is difficult to ensure the repeatability and comfort of the upper and lower jaw and tongue positions Poor and unable to personalize

However, in the prior art, the radiotherapy individualized mouthpiece made of materials such as silicon rubber can ensure positioning accuracy, comfort and realize individualization, but because of its complicated manufacturing method, it needs to be made by professional dentists and technicians. The production time is too long, the disadvantages such as high cost are not convenient for clinical promotion and use
