43 Million Injections have been carried out using The Wand, worldwide

16,000 Wand instruments are used in America

12,000 Wands have recently been ordered by China.



The Wand STA (Single Tooth Anaesthesia) System is the easy alternative to the syringe.

Many patients believe that needle insertion is what causes discomfort during an injection, when in fact most of the pain is caused by the flow of the anaesthetic.

The mere sight of a dental syringe and the thought of having an injection by the dentist can easily make most patients wish they were somewhere else. For patients, this fear can be costly.

At the heart of this device is an on-board microprocessor, which guides the anaesthetic flow rate. The microprocessor inside The Wand™ automatically compensates for different tissue densities and the anaesthetic itself is delivered at a constant pressure and volume so that the injection itself is hardly felt.


The Key Benefits Are:

  • Higher Patient Comfort

  • Reduced Patient Anxiety

  • Faster numbing onset and sensation recovery

  • Especially useful for paediatric patients

  • Confirmation that you are in the right location for intraligamentary injections

  • No more blocks necessary - anaesthetise one tooth, without collateral numbness.

  • Painfree palatal injections, allowing you to view the smile-line immediately

Demonstrates awareness and patient sensitivity and leads to pro-active resolution of patient fear of Dentistry, in general, and dental injections, in particular.

Consumer spending trends support that patients will spend more for what they perceive to be ‘premium’ standard of care.

Milestone Scientific’s award-winning Wand STA Single Tooth Anaesthesia System® unit combines patented, state-of-the-art computer-controlled injection technology with the dentist’s training to achieve more precise injections, improved drug delivery and materially enhanced patient comfort levels.

Dental professionals worldwide enthusiastically agree that the Wand STA Single Tooth Anaesthesia Systemunit is profoundly changing the practice of Dentistry.

Learn why dentists and patients agree that:

"It's the best shot I ever had."

"It's the best injection I ever gave."

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

The Wand STA Single Tooth Anaesthesia 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 Anaesthesia able to be reliably delivered.  These factors have resulted in reduced duration of Anaesthesia, unnecessary collateral Anaesthesia and increased pain associated with tissue damage.

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

In addition to its general use for all dental injections,The Wand STA Single Tooth Anaesthesia System unit is uniquely capable of predictably and more comfortably administering “Single Tooth Anaesthesia” 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 Anaesthesia.  The benefits of administering injections with the instrument are significant for the patient, the dentist and the business of dentistry.


What practitioners are saying about The Wand STA

I no longer stress when I know the last patient of the day needs a restoration on a mandibular molar. The injection itself is nearly painless.  There is a definite learning period and I feel I’m still learning. 

Drs. Lawrence and Jason Lizzack, NJ

“Since introducing the STA into my practice. new patient referrals have skyrocketed. My patients benefit, and so does my bottom-line. I will never go back to the techniques I used before.”

Charles Patterson, D.D.S., M.S., M.B.A.

“Most patients appreciate not having to deal with prolonged numbness, especially if the patient interacts with the public at their place of work or is required to do an oral presentation following treatment.

Instead of separate appointments for routine restorative treatment to avoid anaesthetising opposite sides of the mouth in the same visit, the patient is able to have individual teeth numbed up that are located contra-laterally to each other and combine what was formerly a required two-visit treatment plan into a single visit.

This saves the patient’s time and transportation cost (fuel!) and saves the practice the overhead of an additional visit’s setup.
For a badly abscessed tooth with soft and hard tissue involvement, in addition to a regular block to anaesthetise the region, being able to switch to a PDA and ultimately intrapulpal routes with the same syringe-needle setup, helps manage a “hot” tooth quickly and comfortably.
For patients having local intraoral anaesthetic for the first time, like children and younger adults, the apparatus is perceived less threatening and more modern."

Dr. Treva D. Lee

“Milestone’s STA System is by far the best asset to our practice. The ease of administering anaesthesia to the single tooth has cut the trauma out of the dental experience for our patients.”

Christine L. Maggio, GEFCC Dental Clinic Manager

Like most dentists, I thought I needed a high pressure mechanical advantage to obtain decent PDL anaesthesia, even though it was unpredictable...also somewhat painful to the patient.

All this and more is solved by the STA. A perio probe motion with a controlled flow of anaesthetic in the correct spot is all that's required... Profound anaesthesia... No more missed blocks and pain... Our patients have been blown away by it...”

Hugh Herrington, D.D.S.

“I wanted to let you know how the STA has changed my practice. Our patients are absolutely AMAZED as to how we deliver anaesthetic! We hear on a regular basis, "What was that? Did you just numb my tooth?" As a matter of fact, this morning, a "Veteran Dental Patient" said to me, "Hey Doc...I have to give credit where credit is due...that I even have patients ask if the specialists I refer to use it as well.

It's nice to see children, who have never experienced dental anaesthesia, leave their visit never having to experience the "anxiety" associated with "Syringe-Type" delivery methods. It's stress free for the patients AND the Team!

The STA is also very accurate as well as less threatening. Anaesthetic is delivered and almost immediately we can begin treatment! We as well as the patients appreciate the ability to maximise their visits by doing several quadrants of dentistry at a time. With the Periodontal Ligament feature, we can work on both sides of the lower arch without losing complete feeling of the entire lower arch. As soon as I put the Wand down, I can pick up the hand-piece and start preparing the crown!

We have many patients referring to our practice purely for the the STA experience! I would never go back to the "old school" way of delivering anaesthetic. Not when there is a less threatening more accurate method of delivery available. I can't say enough of about it!

Stacy Becker-Walker, DDSPrecision Dental Care (Microscope Enhanced Dentistry)

“Every day I am amazed at the overwhelming number of positive comments we receive about STA. "Finally" they say, " a shot that doesn't hurt!" STA is not only the my new favorite piece of equipment, it is the single most consistent and effective marketing tool I have even utilised!”

Dr. Jeffrey K. Waters

“I have been using the milestone "wand" for the past 12 years. My patients have appreciated the comfortable injections from a device that doesn't look like a syringe. I have recently upgraded to the new STA and have been extremely happy with the new advances. Although I have used "the wand" for all local anaesthesia, I never had such predictability with single tooth injections as I now have. The PDL monitor and the cruise control are fantastic additions. I would recommend this device to anyone who values their patient's comfort, and would like a predictable approach to single tooth anaesthesia.

Dr. Rob Wortzel Mountainside, New Jersey

“The STA device is a wonderful addition to my armamentarium for several reasons. Not only am I able to anesthetise just one or two mandibular teeth with little to no discomfort for the patient; which both my patient's and I are thankful for, but with the visual display and audible alerts I am able to do so accurately and safely. The device as a whole has helped greatly with marketing, specifically to anxious patients who are fearful of injections.”

Dr. O'Brien

“The STA is a valuable tool that every dentist will benefit from having.

Dr. Mark Weinstein

“Imagine going to a dentist and having no fear. Imagine being a dentist and truthfully saying to your patient that this process will be painless. The STA system makes that happen.

Since I started using the system both my and my patients' stress levels have dropped dramatically. When I inform them that there will be no more traditional syringes used in my practice they seem a bit sceptical, yet once I use the system on them they are totally convinced.

In the first week using the system I have done an extraction, a root canal procedure and many fillings each using only the STA system. Each procedure was completed without pain and the patient left without any observable numbness, totally comfortable. This system is the future of dentistry, no one will want to practice without this system. ”

Mitchell Adler DDS

“The STA instrument has lived up to all the claims I had read prior to purchasing the unit. With very few exceptions, I have been able to deliver profound single tooth anaesthesia in a variety of clinical situations. Feedback from my patients has been positive. I would recommend it to any dentist looking to reduce anxiety and discomfort for their patients.”

Craig Hunter, D.D.S.o

“The STA System has been well-received by my patients due to its refined design and minimal invasiveness. The STA is particularly effective in mandibular posterior applications and I would unhesitatingly recommend the instrument to any dentist wanting to improve his or her anaesthetic toolkit. ”                                                             

Dr. Michael B. Bruno

“I have used the Wand hand piece and the STA System for about the last three years. While the cost is higher for the Wand injection piece, patients tend to react with less distress; many times, they have no idea that I am using a device with a needle.

Parents have also been surprised that the hand piece is simply made of plastic. Moreover, many parents have expressed appreciation that my practice has been willing to “go the extra mile" by investing in advanced technologies to provide the best, most comfortable dental care for their kids, without then turning around and charging them extra fees. From a patient relationship point of view, it is a winning system.”

Dr. Robert Wade

“The STA system is absolutely awesome! I've been using it in my practice for eight months and I could never go back to giving conventional blocks again. It is one of those disruptive technologies, like digital radiography, that are so much better than their predecessors. Let's put it this way ...if I need a local anaesthetic for treatment I'll search out an STA dentist!”

Tom Gallivan, Jr, DDSRutland Vermont

“I have been using the STA.. it is awesome! I was able to anaesthetise a patient that I have NEVER been able to get numb for 10 years. The mandibular block never worked. I ordered a set of those bonded needles as well, but unfortunately, they were lost in transit and I never received them, so I will need to order more. I tell everyone about the STA.”

John Agelopoulos DMD

“Imagine being asked, " Doctor, did you actually use a needle?". The STA makes my day. Every day.”

Cynthia Brattesani DDS

“Today a “not so unusual” thing happened. I say that because most times I see letters about the unusual. I guess we docs need some excitement now that sex, drugs, and rock & roll are out of the question.

I bought the old Wand delivery system back in October of 1999 and started using it immediately. If I remember correctly there was no learning curve at all, and I became a Magician with my magic Wand…almost instantaneously. Today I was reminded how miraculous these little anaesthetic delivery systems are.

The patient had his eyes open while I delivered the mandibular block, but when I was finished he asked me what that was. I can only quote his surprise. I thought you were measuring something, not giving me a SHOT!”. Truth is, most of the time, a patient has to try to feel the injection. I must admit I take as much credit as I can for painless anaesthesia, but I know it’s the machine. Oh, I hardly ever miss a mandibular block and I have no idea where my dental syringe is, and who cares!!”

Dr. Steven J. Negelow

“I have been using the STA System for the past year and am extremely confident in its efficacy. In my professional opinion, there are many advantages to using this injection technology and it has become the delivery system of choice for most mandibular restorations in my practice.

I have practiced in a small community for 28 years and this innovative instrument has been very beneficial to both my patients and me.

The STA System has permitted me to deliver anaesthesia to a lower tooth and begin working immediately. This time-saving method has all but eliminated the non-productive 10 to 15 minutes per patient delay I previously experienced awaiting profound anaesthesia from the mandibular block. I have removed erupted third molars, gained endodontic access and prepared teeth for all-porcelain crowns with the STA.

There is only a minor learning curve, and once comfortable with the hand piece, one will find great success with limited potential for an iatrogenic event. On vary rare occasions, some patients have noted some discomfort in the area of the injection, but these occurrences have not discouraged me from utilising the STA System for most lower procedures as the overwhelming number of patients experience little to no discomfort.

Please feel free to share my office telephone number with doctors interested in discussing my personal and professional perspective and experience with the STA System.”

Dr. Jeffery Smith

Online Survey Comments

This is the second generation of STA I've owned... my first was in 2000. I've purchased two units and it is absolutely one of the "win-win" investments I've made in my career. Children have "shots" without ever knowing what's happened to them. Adults marvel at the single-tooth-anaesthesia in the mandible. My employees won't consider work done on them without it! All the "buzz" is positive”

“The STA has revolutionised my practice as efficiency and production are up due to instantaneous profound anaesthesia. The injections are stress-free and simple for me, and completely comfortable for the patient. The patients can't believe they are anaesthetised so effortlessly and they spread the word quickly!”

What dental distributors are saying about STA

“Last year at a BDM at the Brownstone, we received a presentation by Mitch Rieders of MAR Enterprises which distribute the STA (Single Tooth Anaesthesia) Unit. I didn't pay as much attention to it as many of you because I don't sell it, but I remembered that it sounded and looked pretty neat.

Recently, I have needed an onlay to be placed (on my lower) and my doctor COULD NOT get me numb with 3 carpules of septocaine. She tried twice on 2 separate visits where I wasted my time and her time!. I never thought I would get my temp out and my onlay set. I remembered Mitch and asked him to come into Manhattan to do a demo at my doctor's office. I told him maybe she'd buy it if it worked.

Well as I type an hour after getting back not only do I have my onlay set, but not a single bit of numbness left. I felt absolutely NOTHING when my dentist was using this device and she was able to drill without me feeling a thing!!!

I wanted to send this out to the team to let you know how great this device is. I'm not being paid or given anything under the table, and I can't even sell this device, I just think it's amazing and wanted to alert you all to a success story. For a few thousand bucks, this is 100% DEFINITELY worth the investment for a doctor. ”
