Infra-orbital nerve block anesthesia-extended coverage using intra-oral 'molar approach'

Area of Science:

• Dentistry
• Anesthesiology
• Anatomy

Background:

• The anterior, middle, and posterior superior alveolar nerves innervate maxillary teeth.
• The anterior and middle superior alveolar (AMSA) nerves are typically blocked via the infra-orbital foramen for dental procedures.
• Variations in the middle superior alveolar nerve's course can lead to incomplete anesthesia with conventional techniques.

Purpose of the Study:

• To describe a novel technique for blocking the anterior and middle superior alveolar (AMSA) nerves.
• To address the challenge of incomplete anesthesia due to aberrant middle superior alveolar nerve pathways.
• To enhance the efficacy of maxillary dental anesthesia.

Main Methods:

• A new anesthetic block technique for the AMSA nerves was developed.
• The technique considers potential variant anatomical courses of the middle superior alveolar nerve.
• The procedure aims for reliable blockade of AMSA nerves.

Main Results:

• The described technique provides an alternative approach for AMSA nerve blockade.
• It aims to overcome limitations of conventional blocks when the middle superior alveolar nerve follows an atypical path.
• Improved anesthetic success for maxillary anterior and premolar teeth is anticipated.

Conclusions:

• A new technique offers a solution for AMSA nerve blockade, accommodating anatomical variations.
• This method enhances the reliability of anesthesia for maxillary teeth.
• It represents an advancement in dental regional anesthesia techniques.
