Description

TECHNICAL FIELD [0001] The present invention relates to an orthodontic light therapy device,

In particular, the present invention relates to an optical therapy apparatus in the form of a mouthpiece in which an optical probe of a multi-core introduced from the outside can sterilize the entire surface of the oral cavity.

Many studies have reported that periodontal disease affects cardiovascular disease, low birth weight infancy, rheumatoid arthritis, chronic kidney disease, and upper respiratory disease. This suggests that local inflammation in the oral cavity affects the inflammation of the whole body and may be associated with the onset of systemic disease leading to death. It is important to manage the dental disease.

 Oral diseases are largely divided into tooth decay and other oral diseases. Dental caries is one of the most common infectious diseases caused by infectious bacteria. The tooth cavity is a disease in which the tooth is gradually demineralized by the action of the bacteria that grow in the plaque, which is a biofilm formed on the teeth. The germs of the plaque degrade sugar to secrete acid, and the disinfection results in demineralization of the enamel on the tooth surface, resulting in deterioration of tooth decay. Gingivitis and periodontitis, which are estimated to affect more than 35% of adults, are also diseases caused by bacterial infections, and the sterilization of biofilms in the oral cavity plays an important role.

 Biofilm formation in the oral cavity is a complex process involving about 500 different bacteria, and many studies have reported the effects of photodynamic therapy on bacteria that cause periodontal disease. Photodynamic therapy (PDT) has been proposed as an effective method of removing oral bacteria because of its easy access to the active site of periodontal disease.

Photodynamic therapy (PDT) uses a photosensitizer that absorbs light of a specific wavelength. The photosensitizer has an affinity for bacterial cell wall, and the molecule activated by the light source generates active oxygen or free radical which can damage the bacteria, and the antibacterial effect is generated. Combined use of antibiotics and photodynamic therapies has the advantage of being able to use less antibiotics as it has greater efficacy than antibiotics alone.

Dental caries is the most common oral disease among children's oral diseases and is a chronic disease that progresses slowly. It is well known that Streptococcus mutans, a gram-positive bacterium, is directly related to dental caries among many bacteria involved in dental caries.

Photodynamic therapy (PDT) is one of the most effective treatments, and it requires powerful antibiotic therapy that is selective for only the caries-inducing bacteria without affecting the normal flora in oral cavity.

Clustering of pathogenic oral bacteria in dental implants placed in the mouth increases the likelihood of periplasmic perimetry similar to periodontitis. When the biofilm is attached to the implant, inflammation and bone resorption appear in the adjacent tissue of the implant, which is directly related to the failure of the implant.

Restoration and Preservation One of the oldest clinical dilemmas of dentistry is the question of whether livebacteria remain after vortex formation. Even when the vortex formation appears to be clear to the naked eye, the probe can only detect hard enamel and dentin, and the invisible bacteria lie in the enamel and dental tissues, ready to cause tooth decay as soon as the restoration is mounted. Once the filler is charged, the bacteria can attack the tooth tissue without being interrupted and not found until the large erosion of the tooth fractures and sinks.

Recently, medical field using light emitting diode (LED) has been widening rather than laser. LEDs have the advantage of being comparable to lasers as an alternative light source for low power lasers. In other words, LED is safe and economical because it can treat large area because it can secure large and flat arrays of light of various wavelengths with little heat damage or direct tissue damage.

The LED light source is slightly different depending on the type of the photosensitizer, the irradiation wavelength, the irradiation intensity (mW / cm 2), the irradiation time (min), and the irradiation period (Hz) It is effective for sterilization. As the energy (J / ㎠) by radiation intensity (mW / ㎠) increases, the bacterial death rate becomes higher and the light of visible light wavelength of 400nm wavelength or more is used at high energy. Effect.

The intensity of irradiance (mW / ㎠) for effective sterilization of pathogenic bacteria in the oral cavity is closely related to the range of light irradiation, and the irradiation intensity is 1 to 1/10 of the water at a distance of 5-10 cm There is a characteristic in which the strength is weakened.

In photodynamic therapy (PDT) with LED, an effective method for removing oral bacteria is to use a high intensity irradiance (mW / cm 2) at a distance of 10 mm or less in all or part of the teeth or gums in the oral cavity, , It is possible to increase the sterilizing power of pathogenic bacteria.

Korean Patent No. 10-1478118 is known as a mouthpiece patent using conventional phototherapy. The above-mentioned prior art discloses a mouthpiece having a structure in which a controller capable of controlling a light source can be provided in a treatment apparatus. However, the disclosed mouthpiece has a problem that the treatment light can not be accurately irradiated to the inner side of the teeth.

Particularly, as described above, photodynamic treatment of teeth requires high intensity illumination. For this, the light should be uniformly irradiated in the inner and outer directions of the teeth, and the distance of the irradiated light should be close. To this end, the prior art described above has provided a light emitting element inside the mouthpiece. When the light source is provided inside the mouthpiece, there is a problem that the output of light can not be increased due to heat generated in the light source.

In order to solve such a problem, it is preferable that the light source should be disposed outside and use optical fibers capable of efficiently transmitting the therapeutic light from the light source. In order to illuminate the entire surface of the tooth, the optical fibers of the multi-core must be introduced into the mouthpiece. Therefore, it is necessary to arrange the optical fibers of the multi-core to be able to irradiate the LED light inside and outside the tooth and the gum according to the dental structure, and to maintain the irradiation distance within 5 mm to increase the intensity of the irradiance (mW / A mouthpiece of the structure is required.
