Abstract

The studies made on Dental units revealed that the single light head device used in the classical system is inadequate. The reflector device with double light heads provides light without shadows and thus ensures a larger illumination area, stronger illumination and where necessary, illumination of two separate parts either within the mouth and outside of the mouth, and because it has two distinct sources of light which can be directed independently, the treatment will not be hampered even if one of the reflectors is out of order for any reason.

Description

LIGHTING DEVICE WITH TWO LIGHT HEADS FOR DENTAL UNITS DESCRIPTION

There is a reflector device for the illumination of the inner part of the mouth during the examinations to be made in dental clinics and offices. These devices that are used for gaining clear vision of the inside of the mouth is insufficient in many respects as to be stated below.

There is often a need for another source of light as well during the adjustment process of the prostheses that have come from the laboratories (crown or bridge prostheses, total and partial prostheses etc.) besides the reflector device that is being used for iUuminating the internal part of the mouth. That can be focused on the prostheses on which the dentist has been working to provide ease for the recommendations of the dentist and carrying out his regular work such as (to measure the height, to remove the excesses in the cols and approximate regions, to remove the excesses in the vestibule and lingual surfaces, removal of the parts in the total and partial prostheses causing discomfort for the soft tissues of the patient and similar procedures.) Because these modifications made on the prostheses are very sensitive and range between thickness of 1/lOmm and 1/100 mm. (For instance, the removal of the excesses on the proximal surfaces of the porcelain front bridges or the smoothening of the cutting surfaces can be cited as examples to this.) The work that needs to be carried out needs maximum attention and therefore the prostheses held by the dentist should be iUummated very well. Furthermore, during these corrections, the reflector should once again be focused in the inner part of the mouth and checks should be performed inside the mouth and wrong, missing opr excessive corrections to be made on the prostheses need to be prevented. Because, when the correction is done in the extreme this causes events that are difficult to compensate and problems arise both for the patient and the dentist During the adjustment of the prostheses inside the mouth, the focus point of the reflector needs to be changed very often and the reflector should be focusing sometimes on the inside of the mouth, sometimes on the prostheses itself outside the mouth when he makes the corrections on the prostheses in his hand. This causes loss of time and additional stress both for the patient and the dentist

Furthermore, the dentist sometimes has to instruct the patient to turn his hand right or left during some of the processes he is carrying out inside the mouth (for processes such as pulling out a tooth, treatment, deterge, crown, bridge and total or partial prostheses) in order to be able to effectively see the internal and external surfaces (lingual, palatial, vestibule) of the tooth on which the dentist is working ad this causes the tooth sometimes to get out of the zone where the reflector had been focusing on. For instance, during a deterge process made for the lower chin, while the lingual surfaces of the left molar teeth (internal and external) are being cleaned and when the dentist passes to the lingual surfaces of the right molar teeth, the area that needs to be seen slips right approximately by 30 cm and this requires the reflector to be focused once again to the area that should be seen. Therefore, the dentist is always obliged to relocate the reflector and make the necessary adjustments in order to be able to properly illuminate the area that he is working on. This distorts the concentration of the dentist continuously and causes loss of time as well. This also causes additional stress and loss of time for the patient. Furthermore, the dentist also has to work for a longer time for the same amount of work and causes fatigue.

Furthermore, in certain sensitive cases such as the surgical pulling out of the roots of the upper and lower molar teeth, or the internal tooth closing controls of the tooth cuttings of the same group, all the points of the inside of the mouth cannot be Uhtrninated in the same quality and manner due to the illumination provided from a single point and shadows are observed in certain places. This makes the process even more difficult and affects the quality of the work as well.

Similarly, stronger illumination is needed for sensitive work as I n the example cited in the previous paragraph and when this need is not met, then certain problems pop up. Other than this, the treatment has to be paused and problems and uncomfortable situations happen when the lifespan of the lamp in the reflector devices that are being used are depleted and they turn off or due to any failure or of contact in the buttons.

We have developed the reflector device with cap in order to solve the problems cited above or similar ones to be used in the dentistry units.

The device has been designed completely by myself and following the research I have carried out both domestically and abroad, I have not come across any dentistry unit manufactured or developed in this respect in the dentistry device catalogs that have been published

Picture 1 is a drawing showing the part of Dentistry unit crescents containing the device of this invention.

The device comprises of a male part the inside of which is empty on the middle upper part of the device and this male part is used to fix another part ( 1 ) that is the same as itself and it will be fixed through the carrier arm (2 ) that has been fixed on the part (3) that it has been fixed on. At the bottom of the tips of both of the ends there are parts that go through the mail parts (4) fixed to be used on the carrier arm and as they go inside the part, they are fixed with a suitable screw to the female part (5) and with the help of these two female parts, they are fixed to the tips of the two reflectors (A,B) and a profile iron (6) of suitable length is fixed on them and thus the two reflectors (AJB) comprise of them

.The reflector device is normally mounted to a place close to the front part of the crescent (7) and a tablet (8) that has been placed where the equipment has been placed on that has been fixed from the top of the reflector pole (9) and the reflector arm (10) makes a movement of rotation in the horizontal direction and on the horizontal plane and this reflector device that has been fixed to the tip of the reflector device in the vertical direction and the reflector carrier arm (2) is fixed on the part (3) that is on the tip and furthermore by the help of the mechanism inside it, the reflector carrier arm can help location by the mechanism set

The problems cited above will be solved by the two reflectors (A3) in the device. It will be possible to iUuminate both the inner part of the mouth and also the prostheses on which the dentist is working on by these reflectors and the illumination area will be increased by directing them on neighboring areas in the mouth as well and when they are directed on the same area- then an illumination without any shadow will be attained and various combinations of these factors will be achieved.

.Furthermore, since there are two reflectors (A3) in the dentistry unit that the device is installed on, when the lifespan of one of the light bulbs of these reflectors is depleted, or when there is a defect or lack of contact in the buttons (13,14) the other one will continue to provide light and the treatment can continue without having the need to interrupt This will prevent any unfavorable circumstance both for the patient and the dentist Then the processes of repair or changing the light bulb can be made when the treatment is over.

The 220 C city power in the crescent cabin should be decreased to 12 volts and the transformer (11) providing energy to the light bulb in the reflector should be strong enough to be sufficient for both of the reflectors (A3) (It should be around 100-150W although it changes according to the transformer to be used.) The button (12) present on the tablet will be connected to the 220 V phase entrance of the transformer and will establish the input of energy to the system causing the transformer to give an energy output of 12 V for the reflector device. A connection of this type will avoid the operation of the transformer in an idle manner when the unit is not being operated. The cables of the transformer carrying 12 V output energy are moved along the reflector pole (9), reflector arm (10) and reflector carrier arm (2) and are connected to the first (A) and second (B) reflectors in a parallel manner and the contact of the cables should be don in this manner. In this manner, through the button (12) on the tablet, both of the reflectors (A,B) on the device can be opened and closed. Through the buttons (13,14) on both of the reflectors (A3) o the device, the electrical connections can be made in such a manner that either both of the reflectors can be turned on and off at the same time or either one of them can be turned on or off independent from the other one. The buttons can also be connected in different manners. It can be possible to make another application by modifying the reflector device with double cap by fixing two reflector carrier arms (2) on the tip of the reflector arm (10) and by fixing a reflector (A) on each one of these arms. However, the application by fixing a profile part (6) to the tip of the carrier arm (2) of a single reflector arm as stated above will be more practical and useful for the implementation of this reflector device with double cap.

The device can be manufactured for being installed on units that have already been in use or it can also be offered for use by manufacturing new units while installing this device.
