Design Notes
Contrast PA design: the flexible plastic working tip adapts to the anatomy of the pocket while measuring, the colorstable black graduations on the white body give excellent reading contrast, and the material cannot scratch implant surfaces. Tips are reusable until they bend, the color fades, or the graduation becomes unreadable. Manufacturer literature (PDF).
