Description

{LIGHT RADIATOR FOR WHITENING TEETH}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light beam irradiator for teeth whitening, and more particularly, to a light beam irradiator for teeth whitening which allows an operator to adjust and fix a position and a direction of a light irradiator to a desired position.

Recently, as the desire to improve aesthetics for appearance has increased, dental treatment has been frequently performed, such as teeth correction and tooth whitening.

Tooth bleaching can be seen as a cosmetic tool among younger women these days because of various causes such as drugs, congenital factors, tobacco, and other food coloring. .

At the beginning of tooth whitening, tooth whitening agent was used as the simplest method to obtain a whitening effect by toothbrushing when brushing toothpaste.

However, the amount of the whitening agent contained in the dentifrice was so small that it was not possible to effectively remove the coloring component deposited on the tooth surface.

For more effective whitening treatment, there is also a method of receiving a professional procedure using a whitening pad or laser in a dentist.

This method is excellent in the whitening effect, but it is troublesome to receive outpatient treatment periodically over a long period of time, and expensive treatment cost is required.

Thus, a whitening patch has been proposed as an eclectic alternative which is easy to treat with less cost and has excellent effect.

The whitening patch is a product which is coated with an ointment containing a whitening agent based on a low concentration of carboxy or peroxide. It has a sufficient whitening ingredient and can be used for a long time, and is excellent in whitening effect. In addition, Anyone can use it simply because it is ready for treatment by attaching to the surface.

However, since the adhesive patch attached to the teeth is water-soluble, the whitening patch detaches from the original attachment position due to movement of the muscle around the mouth during prolonged use, and the ointment portion has a problem of irritating or damaging the gum, tongue, or oral mucosa .

In order to overcome this problem, recently developed is a tooth whitening light irradiation apparatus which can apply a whitening agent containing a photoactive agent to a tooth and activate the whitening component by activating the whitening component with a photoactive agent, to be.

However, such a conventional light beam irradiator for teeth whitening can not easily adjust the position of the lamp for irradiating light, and there is an inconvenience in use in which the user is required to undergo long-time whitening treatment in an uncomfortable posture during use.

In addition, since it is fixedly installed on any one of the objects to be mounted, there is a problem that it is highly restricted in space.
