Computer controlled local dental anesthetic system where just one injection at a single tooth is all that''s needed to scientifically, safely and predictably ensure single-session injection precision. It''s even highly effective for multi-quadrant cases. As the dentist advanced the needle the STA system continuously measures and monitors the pressure of anesthetic solution as it exits the needle tip. When the specific resistance of intraligamentary tissue is identified by the STA system, an audible and visible announcement is given to confirm that the periodontal ligament has been positively reached. Anesthetic is delivered at a controlled pressure and rate. Features: 1, the needle is not deflected, precise positioning, controlled to maintain excellent condition. 2, and the flow rate as low as less anesthetic painless, the whole feel particularly comfortable. 3, the unique single-tooth anesthesia, reducing the injection point, anesthesia is insignificant. 4, compared with the conventional injection anesthesia has better predictability. 5, rapid onset, shorter operative time.
