COMPUTERIZED ANESTHESIA

                                   (CompuDent or STA system)

 

What is it?

essentially a computer-controlled dental injection. The flow rate of the local anaesthetic is controlled by a computer. This means that the injection is guaranteed to be slow and steady and therefore comfortable.
Even though Milestone Scientific – – now call their products CompuDent and STA (Single Tooth Anesthesia) System,  – because a lot 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 caused 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?

It simply doesn’t look like a syringe! Welcome to the space age…

As you can see in the photo, the “hardware” looks similar to a miniature computer tower.

On the top of the little tower sits a cartridge with local anaesthetic. A tube connects this to a pen-like

handpiece (which does sport a needle. You’ve gotta get the sleepy juice in there somehow,

but the needle is very tiny.)

The handpiece device looks just like a ball point pen (see below).

 

It is even held like a pen! Using the 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 photo featuring the CompuDent tower above). The safety feature is there to prevent dental staff from accidentally poking themselves while getting rid of used handpieces. However, most dentists  “standard” the left, because they find it easier to handle.
