Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically relates to an orthodontic airway plate and a preparation method thereof. Background Art

[0002] Pierre Robin sequence, also known as Pierre Robin syndrome, is a rare congenital anomaly disease. Approximately 1 in 8,500 newborns is affected by this disease. The characteristics of Pierre Robin sequence are micrognathia, glossoptosis, and cleft palate. The clinical manifestations are intermittent upper airway obstruction and feeding difficulties, which are most severe in the first few months after birth.

[0003] To address these respiratory and feeding dysfunctions, two treatment methods have emerged: surgical treatment and non-surgical treatment. Surgical treatment is further divided into labiolingual adhesion and distraction osteogenesis. However, in labiolingual adhesion, the adhesion site is prone to splitting, the movement of the tongue is also restricted, and at the same time, the effective time of the surgery is limited, and the relief effect is also limited. When using distraction osteogenesis for treatment, an external distractor is usually used. This method has a long treatment period, which may last from several months to one year. At the same time, postoperative complications, poor new bone formation, and unsatisfactory postoperative results or recurrence may occur. Secondary surgery is also required to remove the distractor, increasing the surgical risk for the patient. In addition, the distractor located outside the mouth may also cause negative emotions in the child. At the same time, the treatment cost of this treatment method is relatively high, bringing a certain economic burden to the patient's family. When using traditional non-surgical treatment, the treatment effect is limited, requiring the high cooperation of the patient and family members. And non-surgical treatment needs to be continued for a long time, with the risk of complications, and it also cannot achieve the purpose of radical cure. Therefore, the present invention provides an orthodontic airway plate and a preparation method thereof. Summary of the Invention

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment 1:

[0041] As Figure 1-2 shown, an orthodontic airway plate provided by an embodiment of the present invention includes: an intraoral component 1, a pharyngeal segment 2, and a traction component 3.

[0042] Specifically, the shape of the intraoral component 1 matches the internal shape of the patient's oral cavity. The pharyngeal segment 2 includes a transition part 201 and a pharyngeal inlet segment 202. When in use, the top of the transition part 201 fits against the top of the inner wall of the upper jaw of the oral cavity. The transition part 201 is fixedly connected to the top of the intraoral component 1. The pharyngeal inlet segment 202 is fixedly connected to the side of the transition part 201. The pharyngeal inlet segment 202 is bent downward and enters the throat through the epiglottis. The number of traction components 3 is two. Both traction components 3 are in a smooth "L" shape. The horizontal parts of the two traction components 3 are fixedly connected to the bottom of the intraoral component 1. The vertical parts of the two traction components 3 extend out of the patient's oral cavity. By respectively lifting the two traction components 3, the installation and removal of the entire orthodontic airway plate can be realized.

[0043] The transition part 201 gradually changes from wide to narrow, conforming to the shape of the human upper jaw. The pharyngeal inlet segment 202 is a slender arc-shaped sheet, and the pharyngeal inlet segment 202 can fit against the inner wall of the throat. The transition part 201 and the pharyngeal inlet segment 202 are integrally formed.

[0044] At one end of the two traction components 3 away from the pharyngeal segment 2, traction hooks 3a are provided. The traction hooks 3a are in a circular ring shape. The two traction components 3 are symmetrically arranged. When fixed to the face of the child, it is hung on the two traction hooks 3a through a tape.

[0045] The pharyngeal segment 2 is made of self-curing resin, and the intraoral component 1 is made of silicone rubber material.

[0046] Embodiment 2:

[0047] An embodiment of the present invention provides a preparation method for an orthodontic airway plate, using an orthodontic airway plate in Embodiment 1, including the following steps:

[0048] S1. Making an impression

[0049] First, use a customized impression tray and polyvinyl siloxane impression material to apply it to the upper jaw in the mouth to make an upper jaw impression in the mouth, and then pour a plaster model.

[0050] S2. Model preparation

[0051] Keep the hollow part of the plaster facing upwards, use wax to seal the bottom of the cleft palate corresponding to the upper jaw impression in the plaster model, and apply a separating agent to the inner wall of the plaster model.

[0052] S3. Making an airway plate

[0053] S3.1. Preliminary shaping

[0054] Pour self-curing resin into the position corresponding to the intraoral component of the plaster model. Then connect one end of the acrylic strip to the intraoral component and heat it. The heated position of the acrylic strip softens, so that it bends towards the throat direction to form the pharyngeal insertion section.

[0055] S3.2. Try-on

[0056] Put the preliminarily shaped intraoral component and the pharyngeal insertion section into the child's mouth. The pharyngeal insertion section enters the throat through the epiglottis, and determine the length and bending angle of the pharyngeal insertion section through the epiglottis.

[0057] S3.3. Final shaping

[0058] Use silicone rubber to reproduce the intraoral component of the preliminarily shaped orthodontic airway plate, and use self-curing resin to replace the original acrylic strip. At the same time, insert two traction components at the bottom of the intraoral component.

[0059] S4. Wearing the airway plate

[0060] Put the completed orthodontic airway plate into the child's mouth. After fixing it with denture paste, the denture paste can make the intraoral component fit the inner wall of the upper jaw of the oral cavity to keep the position of the intraoral component fixed. Then stick tape on the child's face so that the tape hooks on the two traction hooks.

[0061] S5. Wearing method

[0062] The child wears it for 24 hours a day, takes it off once a day for disinfection and cleaning, and fixes it in the child's mouth in the same way after reapplying fresh denture paste.

[0063] During the process of making an impression in step S1, it needs to be carried out when the child is awake on the baby bed in the neonatal intensive care unit. To ensure airway safety, a nasopharyngeal airway is installed before taking the impression.

[0064] When making the impression in step S1, place the maxillary impression in a container, and press the maxillary impression tightly against the bottom of the container. Then, pour plaster into the container to wrap the maxillary impression. After the plaster hardens, take out the whole plaster and remove the maxillary impression from the plaster model.

[0065] When trying on in step S3.2, put the intraoral component into the child's oral cavity. At this time, the pharyngeal insertion section is located inside the child's throat, and confirm the length and bending angle of the pharyngeal insertion section through the epiglottis.

[0066] When finally forming in step S3.3, keep the other ends of the two traction components perpendicular to the intraoral component.

[0067] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
