This study introduces a 3D-printed guide for precise local anesthetic delivery in the mouth, improving mandibular anesthesia success and reducing nerve damage risks.

Area of Science:

  • Dental Anesthesiology
  • Medical Imaging
  • 3D Printing Technology

Background:

  • Traditional inferior alveolar, lingual, and long buccal nerve blocks rely on palpation and anatomical correlation for anesthetic deposition.
  • These methods can lead to inaccuracies, patient discomfort, and potential nerve damage.
  • Optimizing anesthetic delivery is crucial for effective pain management in dental procedures.

Observation:

  • Computed tomography (CT) data was used to create a 3D-printed surgical guide.
  • The guide facilitates accurate and repeatable deposition of local anesthetic.
  • The anatomical location for optimal anesthetic deposition was precisely defined.

Findings:

  • The 3D-printed guide enables precise localization for mandibular anesthesia.

  • This technique has the potential to significantly reduce patient discomfort and the risk of nerve injury.
  • It also aims to decrease the incidence of failed nerve blocks and reduce the overall anesthetic dose required.

    • Implications:

    • This method offers a more accurate and safer approach to regional anesthesia in the oral cavity.
    • It provides a foundational framework for future robot-guided anesthesia administration.
    • Potential to enhance patient outcomes and procedural efficiency in dentistry.
