STA Anesthesia System


Go Back
What Is A STA?


The Wand is 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 the manufacturers of the Wand call their products CompuDent and STA (Single Tooth Anesthesia) System, it is still known as the Wand because a lot of people with needle phobia describe it as their “Magic Wand”!

How Does It Help?


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. Other advantages of the STA system include:

Flow Rate

The precise control of flow rate and pressure reliably produces a comfortable injection even in potentially more “difficult” areas like the palate, where the tissue is less elastic.

Better Control

Many dentists enjoy the light weight and easy handling. The penlike grasp allows the operator to rotate the handpiece, which can make it easier to glide the needle into the tissue.
