A Simplified Single-Penetration Technique of IANB (MK Technique) for Mandibular Anesthesia

Owing to the anatomical basis established on the detailed course, distribution and innervations of buccal nerve in the literature, we believe that an effective and extensive buccal nerve block could be achieved when the nerve is anesthetized proximal to its branching point which relates to anteromedial aspect of ramus (retromolar fossa). Though several techniques of inferior alveolar nerve block (IANB) including few single-penetration approaches were already well reviewed and practiced, pitfalls remained in terms of achieving adequate retromolar soft tissue anesthesia, as well as undermining the very importance of contacting the bone and the orientation of the bevel. We propose a simplified single-penetration technique aligning almost similar to conventional technique and its well-adopted landmarks, but still obviating the need for a separate penetration for long buccal nerve anesthesia.
