Intraoral swallowing training aid with open occlusal surface and manufacturing method of intraoral swallowing training aid

Abstract

The invention relates to an intraoral swallowing training aid with an open occlusal surface and a manufacturing method thereof. The training aid comprises an open type fixing frame and a jaw pad;the open type fixing frame is provided with a dental arch-shaped sleeve body, an open space is defined by the sleeve body through an outer edge and an inner edge which are connected with each other, an occlusion surface of an upper row of teeth is exposed out of the open space, and therefore the open type fixing frame can conform to the usual occlusion habit through the exposed occlusion surface; the jaw pad is fixed to the inner edge and corresponds to the jaw side shape of the oral cavity. The open type fixing frame can be manufactured through a gypsum model or 3D printing according to the shapeof the upper row of teeth, the jaw pad is manufactured into a jaw pad prototype through unhardened false tooth substrate resin, and after the open type fixing frame is worn, the tongue abuts against the jaw pad prototype upwards, so that the jaw pad prototype corresponds to the jaw side in the oral cavity to be shaped into the jaw pad.

Description

technical field [0001] The invention relates to an oral swallowing training aid with an open occlusal surface and a manufacturing method thereof, in particular, the training aid can be set on an upper row of teeth, and the occlusal surface of the upper row of teeth is exposed. Background technique [0002] The normal swallowing steps include the oral cavity, pharynx and esophagus. The saliva or food bolus is pushed into the stomach through the coordinated force of muscles in each part. Among them, when swallowing in the oral stage, the tongue will press against the palate, generating pressure. Normal young people can reach 30KPa to 90KPa or higher, and it is best for the elderly to reach 30KPa or more in order to perform better swallowing function, and push saliva or food bolus into the pharynx for the subsequent swallowing stage. [0003] If there is a condition that cannot be swallowed normally, it is called dysphagia in medicine. In the oral stage, dysphagia can produce...

Problems solved by technology

One type of assistive device is Figure 10 and Figure 11 As shown, a jaw pad A is made, the jaw pad A has a thickness H, and the jaw pad A is hung on the teeth by a fixing hook B to fix the jaw pad A in the oral cavity. However, the patient's oral cavity type (such as Gum shape or arch dentition) usually cannot be completely symmetrical and will be partially skewed. However, the traditional jaw pad material has poor elasticity, so it cannot be fully deformed in the insertion path to adapt to the oral shape of different patients. In order to adapt to the insertion path of the jaw pad, some teeth need to be extracted. In addition, the fixed hook B is used to buckle on the occlusal surface of the teeth. When the occlusal surface of the upper row of teeth and the occlusal surface of the lower row of teeth engage Because the fixed hook B forms an obstacle, and after repeated use, the fixed hook B may break off and be accidentally swallowed to cause injury

Another type of assistive device such as Figure 12 and Figure 13 As shown, it is in the form of a denture, including a fitting part C and a jaw pad D. The jaw pad D has a thickness H', and the fitting part C is used to fit on the teeth to fix the accessory on the In the oral cavity, but this kind of auxiliary device also has the disadvantage of poor material elasticity and cannot be fully deformed to adapt to the oral shape of different patients, thus causing the problem of poor fixation effect, and this type of auxiliary device is set on the teeth. The occlusal surface of the teeth cannot be exposed, so the patient does not conform to the usual occlusal habits when swallowing, which affects the patient's willingness to use and the comfort of use
