A light source for a modified aids eliminate tooth surface reflective

FIELD

[0001] The present invention belongs to the field of photography lighting, relates to a method for the complete elimination of secondary light source modified tooth surface reflective member.

Background technique

[0002] Reflective everywhere in daily life, and non-specular reflective sub-reflecting mirror. Specularly reflecting object is present in the smooth surface, or a light reflective environments or other highlighting objects on the object. Non-specular reflective elements is more complex form, the premise under natural light conditions without the use of filters, non-specular reflecting a ubiquitous and can not be completely eliminated. Will be used in the field of photographic polarizing filters reduce or eliminate non-specular reflecting on the subject, but the traditional use of a polarizing filter can not eliminate the source of the reflecting mirror.

[0003] In particular dental prosthetics specialist needs through photographs and denture technician and / or patient to communicate color information. Natural tooth enamel surface in shooting simultaneously exhibit specularly reflecting and non-reflecting mirror, reflecting two kinds of judgment will affect dentin color. Further dentin leaf development, and other personalized fingers projecting structure after removal of the reflective enamel better show up, easy to imitate technicians dentin Personality in and copy the natural teeth. Further treatment using a synthetic resin tooth restoration also benefit from stratified eliminate reflective, color of the resin material would be more accurate selection.

[0004] Now the above effect can be obtained by adding in front of the light source modified conventional macro flash attachments. The disadvantage of this approach is first of all need to rely on traditional macro flash, but with the development of aesthetic dentistry such traditional macro flash light sources can not meet the needs of dental aesthetics of photography. Second, the presence of such a light source installation accessories modified technique sensitivity more than 3 ° angular error will make completely eliminate reflective screen. The course of treatment will reduce the efficiency of repeatedly taking pictures, using only the naked eye can be observed accessories non-reflective surface of the tooth restoration will greatly improve the efficiency of treatment and colorimetric success rate.

Wherein the observation window as a through hole, the through-hole of another modified window as the light source, the light source is modified window for filtering light such that the tooth surface clinician observed through the observation window reflector is completely eliminated. Test showed the clinician to view the tooth surface of the window is modified filtered light emitted from the observation window, the visible light reflecting was completely eliminated.

[0007] After the modified source aids in use of the present invention can be directly visually observed through the observation window, the lens may be placed in the observation window, after flash lamp light source disposed modified photographs window, preferably a window flash head with a modified light source pitch ^ 0.5mm;

[0008] When visually observed, the observation window size greater than or equal to the size of the patient's upper and lower dentition complete.

When [0009] the flash is, the viewing window size greater than or equal to the size of the aperture of the lens filter thread.

When [0010] Further, if the first through hole of a size greater than or equal to the size of the patient and down the complete dentition, the second through hole is equal to or greater than the filter diameter threaded lens, the light source of the present invention, the modified secondary member gross observation using the observation window as the first through hole, the second through-hole as a light source window modification; flash when shooting, the second through-hole as the observation window, the first through-hole as a light source modification window.

[0011] Furthermore, the closer the light source and the observation window modified modified window accessories present invention, the higher degree of convenience visually observed.

[0012] Furthermore, when visually observed, when the light source from the 6 o'clock direction of the patient, the clinician may observe from 9:00 ~ 13 o'clock direction of the patient to the tooth surface of the reflector is completely eliminated.

[0013] Advantageous effects of the invention:

[0014] Compared with the prior art, the present invention satisfies the needs of clinicians observed at any non-reflective surface of the tooth, with the naked eye and easy to use. The present invention can also be used as auxiliaries photography, the camera and light source is not required, the use of more widely. Meanwhile apparatus of the present invention is observed regardless of the photo shooting in the eye, so that the accuracy of clinician identification of tooth color and still provide reduced O
