Latest Patents

One of Johnson's latest patents is an endodontic procedure employing simultaneous liquefaction and acoustic debridement. This ultrasonic liquefaction endodontic system features a graspable handpiece that includes a contra-angle tip assembly with an insert and an internal fluid flow passageway. A portion of the fluid flow passageway passes through a C-shaped receiver located at the end of the receiver, allowing ultrasonic frequency to pass directly to the fluid flowing through the passageway. The fluid flow passageway may be an injection tube, and the tubular body portion of the tip assembly may be injection molded around the injection tube and the insert. Additionally, a supply tube, held in position by tube guides connected to the handpiece, provides a source of flushing fluid with and without pulsed pressure. The fluid pressure pulses may have ultrasonic energy superimposed as the fluid is forced into a root canal.
