Description

Radiotherapy tooth socket

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to facing that uses during department of stomatology radiotherapy.

Background

Oral cancer refers to malignant tumors occurring in the oral cavity, including tongue cancer, buccal cancer, gum cancer, palate cancer, lip cancer, upper and lower jaw cancer, oral cavity bottom cancer, salivary gland cancer and maxillary sinus cancer, and cancer occurring in facial skin, the incidence rate of oral cancer accounts for about 5% of that of malignant tumors occurring in the whole body, and the main treatment methods are surgical treatment and postoperative radiation treatment. When radiotherapy is carried out, the oral cavity of a patient is required to be in an open state, the distance between oral mucosa and tongue and a target area is increased, and the tongue and most oral mucosa or hard palate, soft palate and nasal cavity bottom wall are far away from the high dose area at the periphery of the target area as far as possible. So when carrying out radiotherapy, the patient can often use oral cavity support, and at present, common oral cavity support is including sucking ware or wooden plug, and it all is conventional articles for use to suck ware or wooden plug, does not divide the size, and does not have independent tooth's socket, will lead to oral cavity support to take place to remove in radiotherapy process to lead to putting the position error big.

Disclosure of Invention

Further, the dental socket data on the 3D printed bite plate is derived from the CT data.

The utility model discloses following beneficial effect has:

(1) the dental alveolus matched with the teeth of the patient is arranged on the occlusal plate, so that the occlusal plate can be matched with the teeth of the patient when the patient wears the occlusal plate, and the movement of the tooth socket in the radiotherapy process is avoided through the acting force between the teeth and the dental alveolus, thereby ensuring the radiotherapy effect;

(2) the air holes are formed in the occlusal plate, so that the patients can breathe smoothly in the treatment process, and accidents such as respiratory distress stopping and suffocation caused by the fact that the patients are provided with tooth sockets are avoided;

(3) the handheld ring is arranged, so that the patient can conveniently wear or take off the handheld ring;

(4) the identification piece is arranged on the handheld ring, so that a patient can conveniently identify that the tooth socket of the tooth socket belongs to the upper jaw or the lower jaw;

(5) the dental alveolus data of the 3D printed model is obtained through the CT data of the patient, the data are obtained without taking a model, intermediate steps are reduced, and customization is simple.

The labels in the figure are: 100. a bite plate; 101. a tooth socket; 102. a vent hole; 200. a hand-held ring; 201. an identification member.

Detailed Description

As shown in fig. 1 and fig. 2, the dental brace for radiotherapy provided by this embodiment is used for being placed in an oral cavity to open the oral cavity, and the dental brace of this embodiment is modeled by CT data of a patient and then printed by a 3D printer to be integrally formed by using a safe polymer material, wherein the safe polymer material includes one of photosensitive resin, PLA and ABS.

The radiotherapy tooth socket comprises an occlusal plate 100, wherein the occlusal plate 100 is C-shaped or U-shaped as a whole, and the specific shape of the occlusal plate 100 is similar to that of upper teeth or lower teeth of a patient; the upper surface and the lower surface of the occlusal plate 100 are both provided with tooth grooves 101 matched with teeth of a patient, the upper surface and the lower surface of the occlusal plate 100 are surfaces of the occlusal plate 100 which are positioned in an oral cavity and are respectively contacted with upper teeth and lower teeth, the tooth grooves 101 matched with the teeth of the patient are surfaces of the teeth of the patient which can be arranged in tooth grooves 101, the depth of the tooth grooves 101 is 1/3-1 of the teeth, the occlusal plate 100 is fixed through mutual acting force between the teeth and the tooth grooves 101, so that the occlusal plate 100 is not easy to move in the oral cavity, and the radiotherapy effect is improved. The dental alveolus 101 is obtained according to the data of teeth in the CT data of a patient, a mould taking process is not needed, and the dental alveolus is fast and convenient. The bite plate 100 is located in the oral cavity to block the respiratory tract of the oral cavity, and in order to ensure that the patient can breathe smoothly during treatment, the side surface of the bite plate 100 is provided with the vent hole 102, the side surface of the bite surface refers to the side surface of the bite plate 100 which is placed in the oral cavity and close to the buccal side, and the vent hole 102 is communicated with the respiratory tract in the oral cavity to ensure that the patient can breathe smoothly, so that the vent hole 102 is preferentially arranged in the middle of the bite plate 100 in the vertical direction, and the aperture of the vent hole is 5-15 mm.

The radiotherapy tooth socket further comprises a handheld ring 200 integrally formed with the bite plate 100, wherein the handheld ring 200 is connected with one side, close to the buccal side, of the bite plate 100, is held by a patient and is taken down or worn; the upper surface or the lower surface of the hand-held ring 200 is provided with an identification member 201, the identification member 201 is used for the patient to identify the direction of the mouthpiece, the direction of the mouthpiece refers to the up-down direction of the bite plate 100, and the identification member 201 is one of a convex point, a groove or a colored layer, or the combination of the convex point and the colored layer, or the combination of the groove and the colored layer; it is conceivable that the bumps, the combination of the bumps and the color layer are arranged on the upper surface of the hand ring 200, and the grooves, the combination of the grooves and the color layer are arranged on the lower surface of the hand ring 200, and it is also conceivable that the positions of the bumps, the combination of the bumps and the color layer are switched without affecting the functions.
