Description

Device for sterilization of dental prosthesis}

The present invention relates to a dental prosthesis sterilization device for sterilizing a dental prosthesis.

The information described in this section merely provides background information on an embodiment of the present invention and does not constitute prior art.

In general, dental prosthesis is a denture that artificially supplements some or all teeth when teeth are inevitably removed due to aging or tooth decay, and it is inconvenient to eat food. Various correction materials are used for dental health, such as braces for orthodontic treatment and whitening trays to improve tooth discoloration.

When using such a dental prosthesis, if the microorganisms or bacteria of the dental prosthesis are not removed, the remaining bacteria cause tooth decay or cause hygiene problems, resulting in the dental prosthesis for dental health harming not only the user's teeth but also the health. Therefore, the importance of hygienic cleaning and storage of dental prostheses is emphasized, and accordingly, cleaning agents and storage boxes with multiple functions are being developed.

Recently, UV lamps or lasers are widely used to sterilize dental prostheses. In the sterilization method using the UV lamp, the powerful sterilizing wavelength of 253.7 nm emitted from the UV lamp denatures the DNA of bacteria and viruses to kill them all. It is a revolutionary sterilization method that can sterilize up to 99.9% of bacteria and protozoa, and is widely used because it has a long lifespan of 8,000 to 10,000 hours and is safer than using chemicals.

The denture storage box including the power unit has the convenience of sterilizing the dentures using ultraviolet rays generated from the ultraviolet lamp when the dentures are stored by exposing the ultraviolet lamp to the lower side on the upper side. In addition, reflectors are provided on the inner upper and lower sides of the denture storage box to induce efficient dispersion of ultraviolet rays.

However, although there is a difference in infrared reflectance depending on the metal material of the reflector, the sterilizing ability of the ultraviolet light is significantly reduced due to the change in wavelength of the ultraviolet light reflected through the metal. In addition, a straight UV lamp is provided at the center of the upper side to expose it in a downward direction, but the straight UV lamp has a problem in that it is difficult to effectively sterilize a U-shaped dental prosthesis that is generally formed along the tooth arrangement.

In addition, the conventional denture storage box has a rectangular cross section and one side is curved, so it is generally advantageous to store U-shaped dentures, but there is no structure for fixing the position of the dentures, so the dentures are attached to the metal reflector during the carrying process. Not only can damage to the dentures be caused by bumping into contact, but also there is a problem that the UV lamp can be damaged when the UV lamp is exposed on the upper side and the dentures collide with the UV lamp.

Not only this denture storage box, but also the storage box for braces and whitening trays is easy to store braces and whitening trays, but there is a risk of damage by bumping into one side of the storage box, and a device to separately sterilize braces and whitening trays is not provided, so visit the dentist There is a problem that the sterilization operation is not performed at the right time every day.

The holding portion 240 does not come into contact with the upper surface of the base member 210 after the dental prosthesis 10 is lifted, and the protrusion 241 has a certain distance (d1) with respect to the ground in a certain range (5 mm to 20 mm). mm) (?). Therefore, since the dental prosthesis 10 maintains a spaced state from the upper surface of the base member 210, it is possible to prevent it from being damaged due to contact with the upper surface of the base member 210, and the light for sterilization is emitted from the protrusion 241. It is reflected from the inclined surface 241a of the surface or the upper surface of the base member 210 to be irradiated to the dental prosthesis 10 so as to increase sterilization efficiency.

A concave groove 241b may be formed at the bottom of the protrusion 241 formed in a conical shape, and the concave groove 241b is formed in a shape that is recessed toward the ground so as to be lower than the upper surface of the base member 210. Therefore, the light for sterilization is refracted by the concave groove 241b and directed upward, that is, in the direction in which the dental prosthesis is raised, so that the sterilization efficiency can be further increased.

The handle 230 is formed on one side of the base member 210, so that it can be gripped by a user or a person concerned with dentistry and transported or transported to the sterilization space 115 of the sterilization unit 100.

The blocking member 220 is formed between the holder 240 and the handle 230, and after the stand 200 is accommodated inside the sterilization space 115, the sterilization space 115 emits light (ultraviolet rays) for sterilization. It blocks exposure and serves as a stopper to prevent the mounting portion 240 from leaving the sterilization space 115.

The blocking member 220 is formed with an area substantially equal to that of the cross section of the sterilization space 115, and a transparent film or translucent film for blocking ultraviolet rays is attached. Therefore, the blocking member 220 blocks external exposure of ultraviolet rays to prevent harmful effects on the human body, minimizes exposure of the dental prosthesis, minimizes exposure, and makes it easy to check the operation of the ultraviolet lamp from the outside.
