Description

Technical Field

[0001] This application relates to an oral treatment device, and more particularly to a protective device for oral air polishing treatment. Background Technology

[0002] Tooth surface pigmentation is a common clinical problem, which is mainly solved by air polishing. This involves using compressed gas to drive water and fine sand particles through a nozzle at high speed to impact the tooth surface and remove the pigmentation.

[0003] Several problems frequently arise during air polishing: When polishing the labial and buccal surfaces, the nozzle is aimed deep into the mouth. Although most of the sand particles are blocked by the tooth surface and mouth mirror, some still escape and hit the tongue and palatopharyngeal mucosa, potentially causing pain and discomfort. Throughout the process, a large number of sand particles remain in the patient's mouth. Despite the water flow, this can cause dryness and discomfort, requiring frequent rinsing and resulting in a poor experience. Furthermore, due to the high-speed spraying of the sand particles, despite the negative pressure tube, a significant amount still escapes into the air. These airborne particles can be inhaled by medical staff and patients, causing health damage. Additionally, sand and dust accumulate on exposed surfaces in the treatment room, contributing to contamination and increasing cleaning difficulty. Utility Model Content

[0004] In view of the above problems, this application aims to provide a protective device for oral air polishing treatment, which can be fitted onto the tooth to be air polished during the air polishing process, forming a relatively closed ring space around the tooth, so that most of the air polishing is confined in the space and does not escape.

[0005] The protective device for oral air-blasting treatment of this application includes: a housing;

[0006] The shell is made of transparent plastic, closed at the top and open at the bottom. A first notch is opened on the first side and a second notch is opened on the second side and a second notch is opened on the second side. The shell is used to fit over the subject's dentition so that the tooth to be air-polished is located in the middle of the shell. The first notch is fastened to the first side of the tooth to be air-polished and the second notch is fastened to the second side of the tooth to be air-polished.

[0007] The front of the housing is equipped with a first tube for connecting a sandblasting tool; the rear of the housing is formed with a second tube for connecting a negative pressure device; the first tube and the second tube are respectively connected to the internal space of the housing.

[0008] Preferably, a first silicone sheet is covered over the first notch to seal the gap between the first notch and the dental arch; a Y-shaped first slit is formed on the first silicone sheet, and the dental arch is inserted into the first silicone sheet from the first slit;

[0009] A second silicone sheet is placed over the second notch to seal the gap between the second notch and the dental arch; a Y-shaped second slit is formed on the second silicone sheet, and the dental arch is inserted into the second silicone sheet from the second slit.

[0010] Preferably, the first silicone sheet and the second silicone sheet are fixed to the outer surface of the housing, respectively.

[0011] Preferably, a silicone strip is formed along the lower edge of the housing, extending toward the interior of the housing to seal the gap between the lower part of the housing and the gums where the teeth are located.

[0012] Preferably, a first mounting hole is formed at the front of the housing; a first silicone gasket is fixed in the first mounting hole by adhesive, and a first tube is inserted into the first silicone gasket; the first silicone gasket and the first tube are integrally fixed by adhesive; a second mounting hole is formed at the rear of the housing; a second silicone gasket is fixed in the second mounting hole by adhesive, and a second tube is inserted into the second silicone gasket; the second silicone gasket and the second tube are integrally fixed by adhesive.

[0013] The protective device for oral air polishing treatment described in this application, when fitted onto the tooth to be air polished, forms a relatively enclosed space around the tooth, preventing sand particles from splashing around during the treatment process, and ensuring that the soft tissue mucosa and tongue in the oral cavity are not hit by the sand particles, nor do the sand particles escape into the air.

[0017] The protective device for oral air-blasting treatment described in this application will now be described in detail with reference to the accompanying drawings.

[0018] The protective device for oral air-blasting treatment of this application includes: a housing 10.

[0019] The housing 10 is made of transparent plastic, with a closed upper part and an open lower part. The housing 10 has a first notch 13 on the first side that penetrates the bottom, and a second notch 14 on the second side that penetrates the bottom. The housing 10 is used to fit over the subject's dentition, such that the tooth to be air-polished is located in the middle of the housing 10. The first notch 13 is fastened to the first side of the tooth to be air-polished, and the second notch 14 is fastened to the second side of the tooth to be air-polished.

[0020] A first tube 11 is installed at the front of the housing 10 for connecting a sandblasting tool; a second tube 12 is formed at the rear of the housing for connecting to a negative pressure device; the first tube 11 and the second tube 12 are respectively connected to the internal space of the housing 10.

[0021] A first silicone sheet 15 is covered on the first notch 13 to seal the gap between the first notch 13 and the teeth; a Y-shaped first slit is formed on the first silicone sheet 15, and the teeth are inserted into the first silicone sheet 15 from the first slit.

[0022] A second silicone sheet 16 is covered on the second notch 14 to seal the gap between the second notch 14 and the teeth; a Y-shaped second slit is formed on the second silicone sheet 16, and the teeth are inserted into the second silicone sheet 16 from the second slit.

[0023] The first silicone sheet 15 and the second silicone sheet 16 are adapted to the size of the tooth into which they are inserted by turning outwards from the edges of the corresponding cuts.

[0024] The first silicone sheet 15 and the second silicone sheet 16 are respectively fixed to the outer surface of the housing 10, for example by adhesive.

[0025] A silicone rim 17 is formed along the lower edge of the housing 10, extending toward the interior of the housing to seal the gap between the lower part of the housing 10 and the gums where the teeth are located.

[0026] A first mounting hole is formed at the front of the housing 10; a first silicone gasket 18 is fixed in the first mounting hole by adhesive, and a first tube 11 is inserted into the first silicone gasket 18; the first silicone gasket 18 and the first tube 11 are integrally fixed by adhesive. The first silicone gasket 18 allows the first tube 11 to be tilted appropriately as needed, thereby adjusting the injection angle of the sandblasting jet containing abrasive particles. Similarly, a second mounting hole is formed at the rear of the housing 10, a second silicone gasket is fixed in the second mounting hole by adhesive, and a second tube 12 is inserted into the second silicone gasket; the second silicone gasket and the second tube 12 are integrally fixed by adhesive.

[0027] In use, the housing is placed on the dental arch, with the tooth to be treated positioned in the center of the housing. The abrasive jet is then inserted into the first tube, and the negative pressure device is connected to the second tube. First, the negative pressure device is activated, followed by the abrasive jet. The jet containing abrasive particles impacts the pigments on the tooth surface, causing them to scatter within the housing and then be drawn away by the negative pressure device. After a tooth has been abraded, the housing is slid along the dental arch to position the next tooth in the center of the housing, allowing treatment to begin on the next tooth.
