The Probe CP11.5B/CPQW – (3.5-5.5-8.5-11.5 / 1-2-3-5-7-8-9-10), 6EZ is a double-ended periodontal probe that combines a ball-tipped CP-11.5B screening pattern with a CPQW (Williams) measurement pattern. The CP-11.5B end uses a 0.5 mm ball tip and 3.5-5.5-8.5-11.5 mm reference points, while the Williams end provides 1-2-3-5-7-8-9-10 mm markings for detailed pocket-depth measurement and charting.
This dual-pattern configuration lets clinicians move between periodontal screening and more detailed measurement without changing instruments. The large-diameter 6EZ handle features deep knurling for a fuller grip surface and stable hand positioning. With a 6.5 in (16.5 cm) overall length, this version combines two established probing patterns with a substantial handle profile.
This version pairs the CP11.5B/CPQW combination with the fuller 6EZ handle. Clinicians get a ball-tipped screening pattern and a detailed Williams measurement scale on one instrument, plus a larger knurled grip for stable control during repeated probing and charting.
