Computer-Controlled Local Anesthetic Delivery System
The computer-controlled Wand All Injection System is designed for unparalleled precision and patient comfort.
Milestone Scientific’s Wand All Injection System is a computer- controlled delivery system that guides anesthetic administration with real-time audio and visual feedback on the agent’s exit pressure and the type of tissue encountered.
The system’s patented ergonomic handpiece produces easier, more controlled fluid flow at greater volumes, “enabling pain-free, precise anesthetic delivery regardless of required pressures.”
Unlike traditional techniques that require anesthetizing an entire mandibular block, The Wand’s “dynamic pressure-sensing technology” ensures proper technique to prevent needle deflection for faster-onset, painless palatal injections with “unparalleled predictability, precision and performance,” and without collateral anesthesia. The system is indicated for use in pediatric, cosmetic, and general dentistry, as well as endodontics.
Eight dentists participated in this Dental Product Shopper evaluation of The Wand , rating such features as ease of use, patient reaction, and patient comfort.
Ease of Use and Training
Ease of use of The Wand was rated as excellent by 1 evaluator, as very good or good by 6, and as fair by 1. One of the 3 evaluators who mentioned a learning curve “felt comfortable after 3 to 4 cases,”adding, “It’s simple to operate. I especially like the voice guidance.” Other remarks included, “difficult to see the bevel,” and “must place the unit in visual range, with tubing draped across the patient.”
Training was rated as excellent by 2 evaluators, as very good by 3, and as good to fair by 3. Comments included, “some tips for use weren’t covered sufficiently” and “hard to learn proper technique without a demo patient.” One dentist said, “Not hard to learn,” and another called the company representative “first-class and very helpful.”
The Wand is designed to enable PDL as a predictable,primary injection, replacing the need for an inferior alveolar block for single tooth anesthesia. Patient reaction to STA’s single tooth anesthesia capability was rated as excellent or very good by 4 evaluators and as good by 4. One evaluator said, “Patients preferred not having a numb lip/cheek.”
When asked if patients found The Wand handpiece less threatening, 1 evaluator said “patients loved it” and another said, “It’s still a needle. Some were apprehensive about the additional tubing and equipment.” The handpiece was rated as excellent by 2 evaluators and as very good to good by 6.
Patient Comfort (Palatal and PDL Injections)
Patient comfort during anesthetic administration was rated as excellent by 1 evaluator, as very good by 5, and as good by 2. Comments included “some weren’t comfortable with the increased injection time” and “comfort varies with the learning curve and ability to position the needle optimally.”
Improved ability to administer more comfortable palatal injections, evaluated by 6 dentists, was rated as excellent or very good by 2, as good by 3, and as fair by 1. One dentist mentioned a learning curve.
When asked about improved ability to administer more comfortable PDL injections—rated as excellent by 1 evaluator, as very good by 3, and as good by 4—one dentist reported complaints about a bitter taste, adding, “Most felt nothing—a few felt a slight pinch.”
Decreased Clinician Stress
When asked about The Wand’s ability to decrease their own stress during anesthetic administration, 4 dentists called it very good or good and 4 called it fair. Comments included “mandibular 2nd molar injections are challenging,” “the learning curve, extra time, and tubing/ equipment created stress,” and “couldn’t tell if the dosage would be effective.” One evaluator reported “concern about the new technique and getting sufficiently deep anesthesia in the right places,” adding, “it was usually fine.”
Overall satisfaction with The Wand was rated as excellent by 1 evaluator, as very good or good by 4, and as fair by 3. One dentist said, “Superb. Patients felt nothing during PDLs.”
