DENTAL CARE FOR ALL INTERNATIONAL C4 Gentle Hand-Bur Systems

C4: International sample for educational purposes. A clamp-lock (C4) system (ideally) uses a tray-set of 4 handles with bur sizes #2,4,6,8. These pen-style, pin vise (PSPV) aluminum handles securely anchor 2 mm diameter implements (ideal for dental burs). They are commonly referred to as "craft knives," "exacto knives," or "pen-knives" in India. (Default blades are replaced with dental burs). Exacto handles were originally designed to anchor surgical blades with only hand-grip tightening. They have endured the test of time, having served humanity well for over 90 years. For superior safety in dental use, DCFAI safety protocol requires supplemental clamp-lock tightening. Regular household pliers work fine: one set of pliers stabilizes the small compression collar, while the second set grips the handle's main body for counter pressure tightening. Testing has proven that supplemental mechanical force makes it impossible for a bur to loosen while in use. Our C4 PSPV model is not proprietary; they are globally available in the general marketplace online. Email us for details. Learn about our mission at dentalcareforall.org.
