Solving one of dentistry’s most challenging problems Here at the GNYDM To see The Wand/STA Single Tooth Anesthesia System for yourself, stop by the Milestone Scientific booth, No. 1818. About the author Mark Hochman, DDS, is director of clinical affairs at Milestone Scientific. By Mark Hochman, DDS n Of all the procedures performed on aroutinebasis,theoneprocedurethat isuniversallyperceivedbypatientsas the most fearful and anxiety provok- ing is the dental injection. In spite of the significant advances made during the past 100 years, our profession has yet to conquer one of the greatest chal- lenges of dentistry — or has it? Milestone Scientific, after spend- ing the past decade responsibly and methodically studying this problem, now believes that with the introduc- tionofitsnewinstrument,TheWand® / STA Single Tooth Anesthesia System, this age-old problem has finally been conquered. The Wand/STA Single Tooth Anesthesia System represents the world’s first and only technology that uses the patented Dynamic Pressure Sensing® (DPS® ) technology, which accurately and safely performs a pres- sure-regulatedintra-ligamentaryden- tal injection. The new Wand/STA Sin- gle Tooth Anesthesia System can also perform all traditional dental injec- tion techniques, i.e., inferior alveolar block, supra-periosteal infiltration, etc. All techniques are performed more efficiently, more effectively and virtually painlessly. Milestone’s new technology incor- porates visual and audible real- time feedback, giving clinicians an unprecedented level of control and information when perform- ing a dental injection. The Wand/ STA Single Tooth Anesthesia Sys- tem replaces the antiquated heavy metal dental syringe with an ultra- lightweight disposable handpiece weighing less then 10 grams for supe- rior ergonomics and tactile control. The experience for both patient and dentist is one that is significantly less stressful. Milestone Scientific created and defined a new category of den- tal instruments called C-CLAD® (computer-controlled local anesthetic delivery) systems. These are the only dental injection instruments that have the published scientific data that substantiate the claim of eliminating or reducing pain perception when performing a dental injection. This technology has undergone the rigors of clinical testing that has been performed in numerous universities and research centers throughout the world for more than a decade. These studies are published in some of the most highly respected dental journals in our profession. No other instru- ment, technology or device devel- oped specifically to reduce pain and anxiety while performing a dental injection can currently make that statement. With the introduction of C-CLAD technology, several newly defined injections were also introduced to dentistry.TheWand/STASingleTooth Anesthesia System has been opti- mized to perform these new dental injections. The first of these tech- niques, the anterior middle superior alveolar (AMSA) nerve block, pub- lished in 1997 by Friedman and Hoch- man, is a contemporary technique to achieve maxillary pulpal anesthe- sia of multiple maxillary teeth from a single palatal injection without producing the undesired collateral anesthesia to the lip and face. Subsequently, Friedman and Hoch- man introduced a second injection, named the palatal-approach ante- rior superior alveolar (P-ASA) nerve block, in which pulpal and soft tissue anesthesia of the central and lateral incisors are achieved by a single pala- tal injection. The general reduction in pain perception for all injections has lead to innovative ways to produce more efficient and effective dental anesthesia. In addition to the new dental injec- tions discussed above, The Wand/ STA Single Tooth Anesthesia System improves the success rate of tradi- tional injections such as the inferior alveolar nerve block. Holding The Wand handpiece with its unique pen- like grasp allows the clinician to easily rotate while simultaneously moving the needle forward, increas- ing accuracy by decreasing needle deflection. Advancing the ability to use the new multi-cartridge injection feature, The Wand/STA Single Tooth Anesthesia System provides numer- ous advantages when performing tra- ditional injection techniques. The introduction of The Wand/ STA Single Tooth Anesthesia System represents a material improvement over previous versions of this excit- ing technology. Numerous innovative new features are available in the Wand/STA Single Tooth Anesthesia System, including automatic purging of anesthetic solution that primes the handpiece prior to use, automatic plunger retraction after completion of use, a multi-cartridge feature allow- ing multi-cartridge injections and reduction of anesthetic waste. Milestone Scientific has developed a novel training feature in the Wand/ STA Single Tooth Anesthesia Sys- tem,providingclinicianswithspoken instructional guidance on the use of the instrument and thereby substan- tially reducing the initial learning curve. The Wand/STA Single Tooth Anesthesia System is today’s most advanced C-CLAD technology and represents the next generation of computer-controlled drug delivery instruments for dentistry. References 1.
