Materials used in dentistry are largely self-polymerizing type and photo-polymerizing type. The self-polymerization type is a material that literally mixes two and then naturally polymerizes itself and hardens over time. The photopolymerization type refers to a material that starts to polymerize and hardens by injecting light of the appropriate wavelength suitable for the material. When curing photopolymerized restorations, the photopolymerizer is already an essential device for dentistry.

Description

Ultraviolet rays infrared rays a radiate Light Emitting Diodes wire less Curing light}

The present invention relates to a dental wireless photopolymerizer using a high brightness LED, an infrared LED, and an ultraviolet LED. The photopolymerizers used in the prior art are classified into two types and classified according to the lamp irradiating light.

Halogen photopolymerizers using halogen lamps used as light sources in the past and the present use AC 220V, which is a general power source.Therefore, there is always a risk of electric shock. The lamp has a long life and the lamp has an extremely short life. Since a great amount of heat is generated in the halogen lamp, a cooling fan is essential to cool down the generated heat. As a result, the sound of the fan is distracting to the patient or dentist and the main body and the photopolymerizer are connected by a complicated wire.

The other is a photopolymerizer using a xenon arc lamp as a light source. Since the lamp has several hundred watts of light, it can reduce the photopolymerization time of dental materials to several seconds, but the power supply used also has several hundred watts. If a high-capacity power supply is required and the output terminal for supplying high voltage power to the xenon arc lamp is not electrically insulated, there is a risk of electric shock. Much heat is generated.

Therefore, like a halogen lamp, attach a cooling device to cool the heat.

Due to the mammary gland, mobility is reduced, and eyesight glasses must be worn for the eyesight protection of the patient or doctor during the procedure, which is inconvenient, expensive, heavy, and bulky.

In comparison, the high-brightness LED and the wireless photopolymerizer emitting ultraviolet and infrared rays of the present invention have so many advantages.

First of all, the wireless charging type does not require cumbersome power and uses high brightness LED, so the wavelength range can be adjusted to 200nm ~ 1000nm maximum intensity over 1000mw / cm2. Ni-Cd or Ni-MH, which is a secondary battery that can be polymerized in a few seconds and can be recharged, can be used for 3 seconds 5 seconds 10 seconds 20 seconds 30 seconds. ), Using Li-Lon, Li-PB batteries, D / C bolts, there is no risk of electric shock and no heat, no cooling fan, no noise, Because of its small size, it fits in the hand and, above all, can protect the eyesight of the patient and dentist during the procedure.

In addition, since the long life of the LED lamp is almost semi-permanent, it can be used continuously if only the rechargeable battery is changed, and the production cost is low, and the light guide fixture is rotated 360 degrees and the band-type bellows type By using the light guide insertion control device, it is possible to fit all the light guide tips of various thicknesses from 2mm to 10mm in the thickness of the tip. have.

In addition, the high-brightness LED and wireless curing light emitted by ultraviolet and infrared rays

It is easy to use during the treatment by the dentist, so that the fixture can be detachably fixed or detached at a short distance such as a handpiece, a three-way syringe, a scaler, and an additional function is that the high-brightness LED lamp generates infrared rays and ultraviolet rays. Attaching LED lamps together can increase the effect of sterilization of the oral cavity filled with germs and treatment of teeth treated with infrared and ultraviolet rays.

In addition, if the high brightness LED wireless curing light emitted by the ultraviolet light and the infrared light of the present invention is continuously turned on, the infrared light and the ultraviolet light are emitted to prevent the infection of the patient, the dentist and the dental hygienist assistant, and further sterilize the entire dentist. It can have an effect that can contribute to the public oral health.

The present invention has been made to solve the problems of a halogen photopolymerizer using a conventional halogen lamp as a light source and an arc xenon photopolymerizer using an arc xenon lamp as a light source;

Using rechargeable nickel cadmium batteries (Ni-CD), nickel-hydrogen (Ni-MH) batteries, lithium-ion (Li-LON) batteries, and lithium polymer (Li-PB) batteries. / C Bolt is used as a power source to attach high-intensity LED lamps together with LED lamps that generate both infrared and ultraviolet light. The light is concentrated through the light guide and transmitted through the restoration of the tooth and the polymeric material.

Thus, after sealing, drilling, or deleting it, the LED lamp which hardens the polymerized material rapidly when filling, peeling or pasting the damaged part with dental material such as resin or dental cement, and also emits infrared and ultraviolet light with sterilizing function. It is attached to reduce the treatment time of dental patients and to have the effect of preventing and sterilizing the infection of dentists and dental assistants, the purpose is to carry out quick, safe and comfortable treatment.
