Technology Description

Traditional intraosseous anesthesia techniques often require drilling through bone to deliver local anesthetic, which can cause tissue damage, increase procedural complexity, and elevate patient discomfort. There is a need for safer, more efficient methods to achieve profound anesthesia for dental surgical procedures, especially in cases where conventional injections fail.

Dr. Robert Bowers at the University of Iowa is developing a three-part assembly that enables bending a dental needle to approximately 90 degrees for use in a specialized intraosseous anesthesia technique. This design supports a “woodpecker” approach, allowing the needle to penetrate thin outer bone without drilling by applying moderate pressure and repeated tapping. Unlike traditional methods, this innovation reduces tissue trauma, minimizes risk of accidental needle sticks, and provides immediate and profound anesthesia for challenging dental procedures. By eliminating drilling, this technology offers a safer and more streamlined solution for dental professionals.
