A computer-assisted local anesthesia device that helps administer pain-free injections. System controls the flow rate of the local anesthetic, delivering it smoothly and gently. Device provides automated aspiration and features 3 program settings: intraligamental and palatal injections, infiltrations, and regional nerve blocks. User-friendly touch controls are activated by the foot switch. Light pen grip provides a relaxed working position, and good finger support shows where the needle can be kept in its original position. Device can be used with standard dental needles and anesthetic cartridges—requires no extra costs for special consumables. Even palatal injections can be carried out with less discomfort for the patient.
