Traditionally, clinicians have relied on well-established intraoral techniques, primarily the conventional "bicuspid approach" and the "central incisor approach."
While effective in a majority of dentate patients, these classical methodologies present significant clinical limitations and technical challenges when applied to edentulous patients, individuals with severe bone resorption, or patients with congenital absence of teeth, where standard dental landmarks are either entirely missing or heavily distorted.
To bridge this clinical gap, the peer-reviewed study titled 'Infra-orbital nerve block using alar base approach: A novel landmark and technique' introduces a groundbreaking, highly predictable, and simplified alternative.
Developed and standardized by maxillofacial specialists, this innovative technique establishes the alar base of the nose as a primary, universally constant, and easily palpable anatomical landmark.

Unlike dental roots or mucobuccal fold heights, the alar base remains structurally stable regardless of the patient's dental status or ridge anatomy.
By detailing both an intraoral and an extraoral pathway, the authors outline a precise, step-by-step protocol that guides the needle directly toward the infraorbital foramen.
This comprehensive approach ensures the simultaneous anesthetization of the infraorbital nerve, the anterior superior alveolar nerve, and the middle superior alveolar nerve, providing extensive coverage that spans the upper lip, the lateral aspect of the nose, the lower eyelid, and the maxillary dentition up to the first molar.
Evaluated across a cohort of patients with zero reported complications, this novel technique offers dental and surgical professionals an invaluable tool to optimize procedural efficiency, overcome the anatomical hurdles of the edentulous arch, and significantly enhance patient comfort.
