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.
