Phillip M. Goodman,DDS, MSc, PhD, Dayton, Ohio, has developed the Excellent TorquingSpring (ETS), a device designed to allow orthodontists to torque rootsat the end of treatment to improve patients’ physiological comfort underthe crowns.

According to Goodman, the ETS fits various rectangular wire sizes instainless, tma, and nitinol. It creates either labial root torque orlingual root torque on any tooth anterior to the molars.

The ETS kit comes with small and large springs and a crimping plier.
