1. Orthodontic Caliper (Measuring Gauge) Found
Written in reference to a posting by Dr. John McDonald which follows:
To the group:
Does anyone know where I can find the exact type of measuring gauge shown below? It says European Orthodontic Products on it, which I cannot seem to find on the web. It also has INOX imprinted on it. I would like to buy new if someone can get me a phone number for the company, or used if anyone has some they would like to get rid of.
Dear Dr. McDonald,
I had given up quite a while ago trying to find a nice caliper like the model you posted on ESCO. Then I received a few new catalogs and found a number of models which are nearly identical to your caliper. Please check the following:
1) Dentaurum // 800-523-3946 // catalog No 14 USA // pg 323 // item 042-750- 00 // name = "dental vernier (beerendonk)" // This is absolutely identical to yours with the addition of an extra thumb stud for easier use. Made in Germany.
2) Leone Orthodontic // 800-242-9986 // catalog 2004 // pg 132 // item p1560-15 // name = " dental vernier double tips" // This is essentially the same as your caliper with some cosmetic differences. Leone is an Italian company, but I'm not sure who made the caliper they sell.
3) European Orthodontic Products // 800-328-8021 // catalog 2001 which is still current // pg H2 // item 53302 // name = "Lino-Zet caliper" // This performs nearly the same functions as your caliper, but is different. It is the only caliper of this orthodontic type that I have found with a locking screw to prevent the inevitable sliding of beaks with age. Made in Germany.
4) GAC // 800-645-5530 // catalog 12 // pg 189 // item 17-000-02 // name = "boley gauge" // This performs the same functions as your caliper, but is made in the style of traditional vernier calipers by a company called ORTeam in Italy.
I have learned that the best vernier and dial calipers are made by Etalon in Switzerland (see http://www.longislandindicator.com/A-11.html ), and the best digital calipers are made by Mitutoyo in Japan (see http://www.longislandindicator.com/p135.html ).I believe that Etalon and Mitutoyo calipers can be customized for orthodontic applications, but I do not know if they can be sterilized appropriately for routine intraoral use.
I hope this helps... at last,
