MUMBAI, India, July 7 -- Intellectual Property India has published a patent application (202641063592 A) filed by Srm Dental College on May 20, 2026, for Design And Evaluation Of A Magnetically Guided Automated Mandibular Foramen Locator.
Inventors include Dr. V. Santhosh Devanadhan; Anmitha Krishnaprasad; and Yuvashree M.
The application for the patent was published on July 03, 2026, under issue no. 27/2026.
Abstract: The present invention relates to a magnetically guided automated mandibular foramen locator intended for improving the accuracy of inferior alveolar nerve block administration. The device comprises an extraoral positioning unit incorporating a calibrated anatomical scale, a Hall effect sensor, and a feedback mechanism, along with an intraoral autoclavable magnetic reference unit. The Hall effect sensor detects the magnetic field generated by the intraoral magnet and provides real-time auditory or visual confirmation when alignment corresponding to the mandibular foramen is achieved. The invention minimizes operator-dependent variability, improves reproducibility, reduces failed anesthesia rates, and enhances patient comfort. The system further serves as a portable chairside guidance device and educational training aid for dental practitioners and students.
