A technique for the computerized identification of orthodontic instruments.

Increasingly, orthodontic instruments must leave the chairside or even the clinic in order to facilitate adequate sterilization. The tray system employed in an orthodontic clinic is outlined. Inevitably, there are problems with instruments being lost from these trays and finding some method for individual 'tagging', which is also resistant to autoclaving, would be a useful facility. To address this problem a robust procedure of automatic instrument identification, similar to bar coding, has been deployed. This system, termed matrix coding, not only facilitates easy instrument identification, but also allows every episode of clinical use and sterilization to be recorded. By such a method it could become possible to quickly establish when instruments are likely to require servicing, sharpening or replacement.
