Zadake's Controlled Etchant Placer
One of the most important events in the history of orthodontics was the introduction of direct Bonding. As early in 1950s when Buonocore introduced acid pre-treatment of enamel using phosphoric acid and showed that this increases adhesion. Given that dentin surfaces can easily be over-etched accidentally during adhesive pre-treatments leads to enamel demineralization, loss of bond strength and gingival irritation. This clinical innovation demonstrated a spring fabricated using 21gauge stainless steel wire containing square slot which is a simple, cost effective, and biologically compatible device with excellent etchant control for etching procedure.
