STA painless injection

“For anyone afraid of needles or injections, I can’t say enough good things about this system.”

The mere sight of a dental syringe and the thought of having an injection can easily become big obstruction for most patients seeing dentist. The syringe is the No.1 cause of stress in the dental office and the biggest source of anxiety and fear for the patient.

For those times when you might not look forward to you dental appointment, the STA Single Tooth Anesthesia System® unit and The Wand® handpiece make the visit anxiety-free and more comfortable for you and your family.

Can local anesthetic injections be non-threatening and painless? The answer is yes!

What is Wand® STA? The Wand® STA provides a painless, stress-free alternative to dental anesthesia via syringe. It is a small hand piece that looks like a pen. It delivers a computer-regulated flow of anesthetic and is comfortable for dentist to hold, meaning that the injections will be consistent, accurate, and painless for the patient every time! Most time, injection discomfort often caused by too much anesthetic is delivered too fast in a confined area of tissue. Because these flow-rate control devices inject the anesthesia slowly,which ultimately improve patient comfort.

2. Reduced injection discomfort. No more fear and anxiety!

3. Injections do not produce collateral numbness to the lips, face, and tongue, which means patients can speak clearly and comfortably immediately after injection

4. Uses less anaesthetic to achieve the same result
