STA wand machine is a new computer-assisted method of injection for a local anesthetic in the dental chair. Designed under the supervision of Dr Malamed, one of the most famous anesthesiologists in the USA, this machine is designed to measure the pressure and speed of injection.
According to a lot of researches, after applying numbing gel to the area, patients would barely feel the needle pricking the tissue, yet the pain is usually related to anesthetic liquid (which is acidic) entering the tissue, and dentists usually tend to help the patient out of this awkward situation of fully opened mouth with a needle in the tissue, so rushing through the procedure.
Fast injection of anesthetic makes the situation worse and would inflict more pain.
Using a wand machine, patients can even close the mouth after the wand is inserted in the proper position holding it in their mouth. Patients can comfortably wait till the injection is finished and the dentist does not need to rush anymore as their hands are free, not holding a syringe while hunching over the patient and they can manage other things in the room while supervising the painless numbing procedure.
- It does not look like a traditional metal syringe that was used in dentistry, so much more acceptable for kids or scared patients. It looks like a wand, hence the name.
- Four different modes of injection with a pedal and cruise control give full control to the dentist on the speed of injection.
- The dentist can monitor pressure by a series of lights on the machine, so excess pressure can be easily detected.
- Needs a power point near the patient.
- Expenses for the machine.
- The needles are 10 times more expensive.
- Pt is connected to the machine with a thin hose while injecting
