You will receive 1 credit(s) of continuing education credit upon successful completion of this course. The purchase price of this course is $49.00


This course describes a new computerized injection system for local anesthesia.


Learning Objectives:

Upon completion of this course, participants should be able to do the following:

  1. Discuss the overall history of local anesthesia.
  2. Describe the tactile difference between a computer-controlled injection and a traditional syringe injection.
  3. Explain the new anterior middle superior alveolar injection.
  4. Administer a predictable, modified wand-assisted periodontal ligament injection in lieu of an inferior alveolar block.


This course describes a new computerized local anesthetic injection system for pain control. The core technology of this system is the microprocessor-controlled delivery of anesthetic solution at a constant pressure and controlled volume, regardless of encountered variations in tissue resistance. This fine-tuned, high suffusion flow rate of anesthetic provides a rapid onset of anesthesia for most patients. Traditional block injections and infiltrations as well as palatal injections and periodontal ligament injections are administered with precision, ease, and patient comfort.
