Medical Forum / General / Dentistry / January 2006Anyone here use one?
I'm considering the possibility of buying one of those devices that have come out for assisting in shade determination. I've read about the X-Rite Shadevision and the Vita Easyshade. Do any of you here have any experience with these? Any comments will be appreciated. Jorge Bonilla DMD With the exception of patients under 30 years of age, use A-2, A-3 and Kohler-White-Bleach-Shade. Throw the rest of the tabs out. Unless you are trying to match to existing fillings and want your restoration to look like it has a filling in it, also. If you take your shade to the tooth you are working on with _NO_ filling in it and the buccal wall of enamel intact, it will be A-2 or A-3. I just saved you a bunch of money. The Vita electronic shade device is nice, but does not print out (last time I checked it). You have to have it in front of you while you stain and glaze, or you have to transfer the data from its screen to a sheet of paper. I find it hard to write on toilet paper, so prefer things which will print on their own, or which will store data for later retrieval.

In the Magical World of CEREC, where we only try to match the residual tooth, and never try to match a tooth that is full of amalgam or composite, everything is A-2 or A-3, unless they have bleached to Toilet White. The other shades are only needed when you are trying to match a previous PFM, or you want the tooth to look yucky like the one next door (which is full of filling).

Do you use a color corected shade wand ? I see alot of D-3. Mebbe it's a local thingy, tetracycline, perhaps ? For esthetics, (especially anteriors, and bi's) nothing beats stacked porcelain. >In the Magical World of CEREC, where we only try to match the residual >tooth, and never try to match a tooth that is full of amalgam or composite, [quoted text clipped - 24 lines] >>> paper.

SP SignatureTake out the TRAASH to reply A2 & A3 see the most use by me too, but I also enjoy the challenge of difficult shade matches. Haven't gone digital but the Brooks Air Force website has a pretty good synopsis of the available systems: https://decs.nhgl.med.navy.mil/DIS68/sec13.htm#DIS68020 Jane Brewer over at SUNY Buffalo has been playing with digital shade-scanning for years. On the average it improves shade matching but this is, of course, a very individual skill. Some people are very good and some never will be, and the latter benefit the most from digital methodology. In addition to the body shade it is critical to indicate other color- affecting variables, the distribution of the incisal being most significant and the one that my residents screw up the most. >I'm considering the possibility of buying one of those devices that >have come out for assisting in shade determination.

Lab must be compatible. -- Whamatus Take out the G'RBAGE wubbabubbazG@RBAGEyahoo.com 2 problems with these shade matchers. 1) teeth have more than one colour to them. 2) these shade guided are nice but the compatability to the porcelain being used, the material underneath the porcelain, the thickness of the porcelain or just the uniqueness and metamerism of the tooth colour and lack of a porcelain materials that perfectly match to the tooth, are the biggest problems with these units. |
