STA Single Tooth Anesthesia System

The patented, award-winning STA Single Tooth Anesthesia System unit utilizes computer-controlled local anesthesia delivery to enhance the injection process for both the dentist and the patient.

The STA Single Tooth Anesthesia System unit incorporates the "pressure force feedback" elements of Milestone's patented CompuFlo system with DPS Dynamic Pressure Sensing technology and consists of a computer-controlled drive unit about the size of a cable modem (5" L x 2"W x 5" H), and a separate single-use disposable handpiece/needle assembly. The core technology utilizes an electro-mechanical motor regulated by a central processor unit (CPU) functioning in concert with a force/pressure transducer.

Traditional syringe techniques utilized in routine intraligamentary injections are hampered by the blind nature of the injection, the extreme pressures generated in local tissues during the procedure, and the relatively small volume of anesthesia able to be reliably delivered. These factors have resulted in reduced duration of anesthesia, unnecessary collateral anesthesia and increased pain associated with tissue damage.

The STA Single Tooth Anesthesia System unit takes the guesswork out of the administration of anesthetic by providing real-time visual and audible feedback via the CompuFlo system with DPS Dynamic Pressure Sensing technology. During an injection with the STA Single Tooth Anesthesia System unit, the CompuFlo system with DPS Dynamic Pressure Sensing Technology continuously monitors the exit pressure of the anesthetic in real-time during all phases of administration.

In addition to its general use for all dental injections, the STA Single Tooth Anesthesia System unit is uniquely capable of predictably and more comfortably administering "Single Tooth Anesthesia" into the Periodontal Intraligamentary (PDL) space, something never before possible using conventional techniques. This injection results in the patient having no collateral numbness and no pain along with instant, predictable anesthesia. The benefits of administering injections with the instrument are significant for the patient, the dentist and the business of dentistry.
