A closed-mouth approach for the mandibular nerve block, It anesthetizes the following nerves: ● Inferior alveolar nerve (and its branches, the mental and incisive nerves) ● Mylohyoid nerve ● Lingual nerve Useful when mandibular depression (opening) is limited, such as with trismus Considered a “blind” injection Often used in patients with a limited ability to open the mouth and when intraoral landmarks for a standard inferior alveolar nerve block are difficult to view Good for patients with a strong gag reflex or macroglossia
