What is it?
Even though Milestone Scientific - the manufactureers of the Wand - now call their products CompuDent and STA (Single Tooth Anesthesia) System, we'll still call it the Wand here - because alot of people with needle phobia describe it as their "Magic Wand".
Most people who have had a bad experience with injections think that needles sting because the skin is pierced, but this is usually not so! Most often, the sting was cased because the anesthetic was fired in too quickly. Obviously, it is possible for the dentist to control the speed with a standard syringe, but the idea of the Wand is to take out the "human error". This can be very reassuring for people with previous bad experiences.
What does the Wand look like?
As you can see in the photo, the "hardware" looks similar to a miniature computer tower.
The handpiece device looks just like a ball point pen.
It is even held like a pen! Using the Wand is very enjoyable for the operator (that is, the dentist) because it is so light and easy to handle. To start the computer, the dentist uses a footpedal connected to the computer tower. The computer does the rest. That way, the operator can focus all attention on holding the handpiece in the right position.
The cartridge holder, tube and wand handpiece are all single-use disposables.
A "cool blue" "safety" wand handpiece with a self-retracting needle is also available (shown in the right-hand photo). The safety feature is there to prevent dental staff from accidentally poking themselves while getting rid of used handpieces. Howerver, most dentists prefer the "standard" wand on the left, because they find it easier to handle.
