Desensitization reagent fixing device for treating dentin hypersensitivity as well as preparation method and forming method of fixing device

Abstract

The invention relates to a medical instrument for fixing dentin hypersensitivity reagents and particularly relates to a desensitization reagent fixing device for treating dentin hypersensitivity as well as a preparation method and a forming method of the fixing device. The fixing device is formed into a tooth socket shape and mainly comprises a tooth support part and a sensitive treatment region,wherein the tooth support part is formed into a stereoscopic film cavity structure matched with a whole dental arch, and an inverse concave structure is arranged at an opening of the tooth support part; and an accommodating cavity structure is preset in depth or width surface of the tooth support part in a thickness range of 0.12mm-0.28mm far away from a tooth body so as to form the sensitive treatment region. The invention aims at providing the desensitization reagent fixing device for the mass patients with dentin hypersensitivity after the radiotherapy of head and neck tumors, the patient can put desensitization reagents into a tooth body sensitive part in the device and wear the fixing device in an oral cavity, so that the convenience, accuracy, timeliness and repeatability of the patient in the use process of the desensitization reagents are improved, the problems of inconvenience, boundedness and the like of the patient in the operation process are solved, and the treatment effect of the dentin hypersensitivity is improved.

Description

technical field [0001] The invention relates to a medical instrument for fixing a dentin desensitization reagent, in particular to a desensitization reagent fixing device for treating dentin hypersensitivity and a preparation and molding method. Background technique [0002] Dentin hypersensitivity (dentin hypersensitivity), also known as dentin sensitivity (dentin sensitivity), is manifested by external stimuli such as temperature (cold, heat), chemical (sour, sweet), mechanical (rubbing or biting hard objects) and other effects. Teeth soreness and pain symptoms are characterized by a sharp, short-lived and rapid-onset pain. The pain is characterized as transient, and the pain disappears immediately after the stimulus is removed. However, some patients also show dull pain and discomfort. [0003] There are many reasons for the patient's dentin hypersensitivity in daily life, such as: teeth grinding at night, mild to moderate physiological wear and pathological wear, bad too...

Problems solved by technology

But on the other hand, since the treatment of tooth hypersensitivity cannot achieve immediate results or long-term lasting effects, and the symptoms of dentin hypersensitivity are recurring, even after the dentin hypersensitivity symptoms are resolved or relieved, there may still be the following dentine hypersensitivity in the later stage. Dental hypersensitivity occurs again due to the exposure of small tubes, so patients treated in the clinic need to go to and from specialized hospitals many times, which is tiring, time-consuming and labor-intensive, and the effect may not be ideal. Patients with dentin hypersensitivity are painful, and it is aimed at tooth pain. To solve the problem, patients now hope to choose desensitization reagents that are more portable and usable, and can be operated at home to complete desensitization treatment, such as the use of common desensitization toothpaste on the market, desensitization Gel etc.

[0005] At present, there are many kinds of household desensitizing reagents for dentin hypersensitivity, and the market supply is also large, but the effect is uneven. However, these products all have one thing in common, that is, they need to be operated by the patient themselves. However, in the actual use process It was found that most patients were affected by the fluidity of desensitizing reagents, the three-dimensional shape of the teeth, the sensitive parts and quantity of the teeth, the limitation of the visual range of the patient's operation and the limitation of the operable space, etc. Influenced by various aspects, coupled with the tension and degree of the muscles around the oral cavity, the desensitization reagents are affected by oral environmental factors such as oral saliva in the oral cavity, etc., many factors make it difficult for patients to successfully and accurately desensitize the desensitization reagents. The reagents are applied or wiped to the sensitive and painful parts, or even not in place at all. The repeatability of the whole process is poor, the positioning accuracy is low, and at the same time, it is impossible to guarantee the time for the desensitizing reagents to stay in the sensitive parts of the tooth, so that the dentin The desensitization effect of sensitivity treatment is affected, and the discomfort of tooth sensitivity pain cannot be solved or relieved, resulting in poor treatment effect of dentine hypersensitivity

[0006] Although there are also dental braces for correcting teeth or for applying medicine in the prior art, such as the patent No. "201110396532.8", the patent title is "the manufacturing method of invisible aligners and its products", and the patent No. It is "201010121981.7", and the patent title is "Dental mouthpiece for drug administration on tooth surface and its production method". The dental mouthpiece for tooth surface administration is made of rubber material, but the raw material thickness of the mouthpiece made of rubber It is thicker, the taste of raw materials is heavy, the rubber material is easy to age, and the mouth feels heavy when worn, which affects the image under special circumstances during the day, and feels uncomfortable due to joint discomfort and heavy foreign body sensation when sleeping at night, and cannot sleep comfortably and peacefully. Various factors in the process eventually lead to prolonged treatment and slow curative effect, and the overall limitation of the material structure makes it impossible for patients to use comfortably

The principle of the invisible aligner is to achieve the purpose of correcting the malocclusion of the teeth by wearing the aligner, so as to move the teeth to the designated position purposefully. The teeth will exert a certain amount of additional pressure, so as to achieve the effect of moving the teeth. When wearing the appliance, the inner tissue surface of the appliance and the surface of the tooth body are in close contact and exert pressure on the tooth surface. Through this additional force on the teeth To achieve the function of moving teeth, but this additional force on the tooth body to make the tooth shift function is useless or even harmful for patients with dentin hypersensitivity
