Apparatus for simultaneous illumination of teeth
View Patent ↗An arrangement, for use in whitening a patient's teeth includes an arched surface and an array of light-generating devices, for example, light emitting diodes positioned on the arched surface. The light-generating devices are arranged to form a relatively uniform field of light in a particular range of wavelengths, and further arranged to focus the generated light in an overlapping manner onto a patient's teeth when the mouthpiece is properly positioned relative to the patient's face. The proper positioning is aided by a number of light sources, in the visible range, that shine on the patient's face in a predetermined manner when the mouthpiece is properly positioned. To remove whatever heat is generated at the surface of the patient's teeth in the course of the procedure, the mouthpiece includes air passages between the light emitting devices, and a fan that draws air away from the patient's face.
1. A tooth illuminating apparatus comprising:
a mouthpiece including a light source for projecting light energy onto the labial surfaces of plural teeth of a subject and at least one mouthpiece index disposed at a predetermined position relative to the light source, said at least one mouthpiece index comprises a dimple in a surface of said mouthpiece; and
a positioner having at least one bite member adapted to be held by the subject between the subject's teeth and at least one locator disposed at a predetermined position relative to said at least one bite device, said positioner being adapted for attaching to said index;
wherein said positioner includes a spacer rod having an end connected to said bite member, said at least one locator comprising another end of said rod adapted to be received into said dimple.
2. The tooth illuminating apparatus of claim 1 , wherein:
said light source projects light from said mouthpiece in a predetermined pattern relative to the occlusal plane of the subject's teeth; and
said positioner places said pattern in a predetermined spatial relationship with the subject's teeth when said at least one bite device is held between the subject's teeth.
3. The tooth illuminating apparatus of claim 1 , wherein said mouthpiece further includes a mount for attaching said apparatus to a movable mounting arm.
4. The tooth illuminating apparatus of claim 3 , wherein said light source projects a field of light with a substantially uniform light intensity onto the subject's teeth.
5. The tooth illuminating apparatus of claim 3 , wherein said light source emits actinic light for activating a photosensitive composition applied to the subject's teeth.
6. The tooth illuminating apparatus of claim 5 , wherein said actinic light has a wavelength in the range of about 350 nm to about 700 nm.
7. The tooth illuminating apparatus of claim 6 , wherein said wavelength is within the range of about 400 nm to about 505 nm.
8. The tooth illuminating apparatus of claim 1 , wherein said light source projects a field of light with a substantially uniform light intensity onto the subject's teeth.
9. The tooth illuminating apparatus of claim 1 , wherein said light source emits actinic light for activating a photosensitive composition applied to the subject's teeth.
10. The tooth illuminating apparatus of claim 9 , wherein said actinic light has a wavelength in the range of about 350 nm to about 700 nm.
11. The tooth illuminating apparatus of claim 10 , wherein said wavelength is within the range of about 400 nm to about 505 nm.
12. The tooth illuminating apparatus of claim 1 further comprising at least one aperture disposed in a proximal portion of the mouth piece; and
a passageway internal to said mouthpiece extending from said at least one aperture towards a distal portion.
13. The tooth illuminating apparatus of claim 12 , wherein said passageway is for drawing air away from the teeth of the subject through said at least one aperture.
14. The tooth illuminating apparatus of claim 12 further comprising a fan for drawing cooling air through said mouthpiece.
15. The tooth illuminating apparatus of claim 14 , wherein said fan is oriented to draw air from said passageway of said mouthpiece.
16. The tooth illumination apparatus of claim 12 wherein said light is pulsed, continuous, interrupted continuous or combinations thereof.
17. The tooth illuminating apparatus of claim 1 wherein said light energy is pulsed, continuous, interrupted continuous or combinations thereof.
18. The tooth illuminating apparatus of claim 1 further comprising at least one filter for limiting the wavelength of light emitted from the light source.
19. The tooth illumination apparatus of claim 1 , wherein said light illuminates both upper and lower arches of said subject simultaneously.
