Milestone Scientific Launches FDA-Cleared Single Tooth Anesthesia (STA(TM)) System During Chicago Midwinter Meeting

LIVINGSTON, N.J., Feb. 20 /PRNewswire-FirstCall/ -- Milestone Scientific, Inc. , a world leader in computer controlled local anesthetic delivery, will officially unveil its highly anticipated Single Tooth Anesthesia (STA(TM)) System during this year’s Chicago Dental Society Midwinter Meeting. Milestone will be conducting demonstrations of the STA System at booth # 2206.

The FDA-cleared STA System is comprised of a computer-controlled drive unit and a single-use disposable handpiece/needle assembly. It provides newly-patented real-time visual and audible feedback and verbal announcements via Milestone Scientific’s patented CompuFlo(TM) with Dynamic Pressure Sensing (DPS(TM)) technology, thus taking the guesswork out of the administration of anesthetic.

Specifically, the STA System enables the dental professional to precisely administer an intraligementary injection to anesthetize a single tooth in only one to two minutes*, rather than administering a mandibular block that anesthetizes an entire quadrant. The STA Intraligamentary injection has an immediate onset, whereas the typical block injection can take 8 to 12 minutes before a dentist can start treatment. In addition, the STA intraligementary injection last as long as a traditional infiltration or mandibular block. All of this is accomplished with a technology that has been clinically proven to provide a pain-free injection.

* Using 4% Articaine Hydrochloride 1:200,000 local anesthetic solution.

Using the innovative CompuFlo with DPS technology, the STA System informs the clinician of the exact location of the needle point between the tooth and bone to directly target the periodontal ligament in order to comfortably anesthetize a single tooth without causing collateral numbing of the cheek, lips and tongue or histological damage commonly associated with the traditional PDL injection.

Moreover, the STA System has been programmed to measure the precise “exit pressure of an anesthetic as it is injected into tissues of varying density. It provides constant information so that the dental professional is in the optimal location during the entire injection.

Furthermore, unlike traditional syringe injections, the STA System allows the dental professional to start working immediately after the injection is administered, resulting in definitive and uninterrupted treatment saving valuable chair time. It also allows work to be performed in multiple quadrants and in both arches with ease, precision and efficiency, thus allowing multiple procedures to be completed in a single office visit.

The STA System incorporates Milestone’s CompuDent(TM) technology which was introduced in 1998 and marked the first major advancement in local anesthetic delivery since the syringe was invented more than 150 years ago. Milestone’s STA System is well-positioned to make a significant and positive impact on the predictability and productivity of the dental practice while improving the overall patient experience, by eliminating collateral anesthesia with a pain-free injection.

Milestone received FDA 510(k) Pre-market Notification acceptance in August 2006 for the marketing and sale of the STA System and has since entered into an exclusive United States and Canadian distribution agreement with Henry Schein, Inc. , the world’s largest provider of healthcare products and services to office-based practitioners in the combined North American and European markets.
