Description

Dental light generating apparatus with light source arranged remote therefrom

The present invention relates to a dental light supply device including a photocuring device for curing light by irradiating light to a photopolymerizable composition filled in a defective part of a patient's tooth due to a lamp and a tooth used in a dental procedure. More specifically, the present invention relates to a dental light supply device disposed at a distance from a patient's head and a doctor to protect them from electromagnetic waves and noise generated from a light source.

In dental treatment of patients, dental lighting lamps are now used which irradiate strong light from above the head of the patient and near the mouth. Such dental lighting lamps are typically used attached to a dental chair, an example 100 of which is shown in FIG. Halogen lamps or halogen-tungsten lamps are generally used as the lighting lamps, and it is generally required to irradiate light with strong illumination ranging from 1,500 lux to 2,500 lux. In the process of generating strong light, strong electromagnetic waves Together with noise.

However, as described above, since these lamps are located directly above the head of the patient, there is a problem in that strong electromagnetic waves and noise generated by the illumination lamp have a harmful effect on the patient. Moreover, since the dentist who is located next to the patient and performing the procedure is exposed to strong electromagnetic waves and noise for a long time during the treatment and treatment of several patients, such harmful effects are more severe for the doctor. However, no solution has been proposed for the harmful environment caused by electromagnetic waves and noise of the dental lighting lamp.

On the other hand, in dental treatment, dental photopolymerizable composition comprising a polymerizable monomer, a polymerizable initiator, and an inorganic filler is used for the restoration of tooth decay to improve physical strength, abrasion resistance, coloration, and shaping. Thanks to this, it is widely used. Among them, the photopolymerizable composition which causes the polymerization by irradiating light of a specific wavelength is easy to use and manipulate, and thus the use thereof is increasing. Such photopolymerizable compositions include surefil (registered trademark) of Dentsply Caulk, USA, Z100 (registered trademark) of 3M, and Aelite Flo (registered trademark) of Bisco, Inc., and the like.

In order to cause photopolymerization of such a photopolymerizable composition, a dental photocuring apparatus for irradiating the photopolymerizable composition with light having a specific wavelength in the range of 300 nm to 1000 nm and curing the composition is widely used. 2 illustrates an example of such a dental photocuring device 200, and the disclosed documents include US Pat. Nos. 6,033,223 and 6,046,460. On the other hand, a halogen lamp or the like is usually used as a light source of such a dental photocuring device.

Since the dental photocuring device must irradiate the photopolymerizable composition filled in the patient's mouth, specifically the missing portion of the patient's teeth, it should be placed in a position very close to the patient's head. Typically, by rotating the table installed in the dental chair as shown in Figure 1 very close to the patient's head, by placing a dental photocuring device on this table to irradiate light of a specific wavelength, The photopolymerization procedure is performed.

On the other hand, the dental photo-curing device generates high-frequency electromagnetic waves known to be harmful to the human body in the process of generating the light of the specific wavelength described above, and because the dental photocuring device is disposed very close to the patient's head and used Dentist is being exposed to strong electromagnetic waves. In addition, such a device also generates noise along with electromagnetic waves, which is also pointed out as a poor surgical environment.

However, the dental photocuring apparatus used conventionally is not provided with a means for overcoming such harmful environment, and the above-mentioned document also does not disclose any means for preventing such electromagnetic waves.

Therefore, one object of the present invention is to place the light source of the photocuring device and the illumination lamp at a distance from the patient's head to reduce the electromagnetic waves and noise applied to the patient and the doctor being treated, thereby eliminating harmful treatment environment It is to provide a dental light supply device.

Another object of the present invention is to integrate the light source of the photocuring device to the tray table attached to the dental chair to provide a dental light supply device to facilitate the photocuring procedure and to increase the utilization of the tray table during the photocuring procedure It is.
