Mandibular Technique Flashcards
The second most frequently used (after infiltration) and possible the most important injection.
Inferior alveolar nerve block
Nerves anesthesized of inferior alveolar nerve
Inferior alveolar nerve, brach of posterior division of the mandibular trigeminal nerve
Incisive nerve
Mental nerve
Lingual nerve
Areas anesthesized of inferior alveolar nerve
Mandibular teeth to the midline
Body of the mandible, inerior potion of te ramu
Buccal periosteeum, mucous membrane anterior to the mental foramen (mental nerve)
Anterior two-thirds of the tongue and floor of the oral cavity (lingual nerve)
Lingual soft tissues and periosteum (lingual nerve)
Area of insertion of inferior alveolar nerve block
Mucous membrane on hthe medial side of the mandibular ramus, at the intersection of the lines - one horizontal, representing the height of needle insertion, the other vertical, representing the anteroposterior plane of insertion
Target area of inferior alveolar nerve block
Inferior alveolar nerve as it passes downward toward the mandibular foramen but before it enters into the foramen
Landmarks of the inferior alveolar nerve
Coronoid notch (greatest concavity on the anterior border of the ramus)
Pterygomandibular raphe (vertical portion)
Occlusal plane of the mandibular posterior teeth
A branch of the anterior division of V3 and consequently is not anesthetized during IANB. Nor anesthesia of the ___ nerve is necessary for most restorative dental procedures
Buccal nerve block
Nerve anesthesized of buccal nerve block
Buccal nerve
Area anesthetized of buccal nerve
Soft tissues and periosteum buccal to the mandibular molar teeth
Target area of buccal nerve block
Buccal nerve as it passes over the anterior border of the ramus
Landmarks of buccal never block
Mandibular molars, mucobuccal fold
The true mandibular nerve blockbecause it provides sensory anesthesia of virtually the entire distribution of V3
Inferior alveolar, lingual, mylohyoid, mental, incisive, auriculotemporal and buccal nerve are blocked by the technique
Mandibular nerve block: The Gow-Gates technique
Nerves anesthesized of the gow gates technique
Inferior alveolar nerve
Mental nerve
Incisive nerve
Lingual nerve
Mylohyoid nerve
Auriculotemporal nerve
Buccal nerve (75% in patients)
Areas anesthetized by gow gates injection
Mandibular teeth to the midline
Buccal periosteum and mucous membrane on the side of injection
Anterior 2/3 of the tongue and floor of the oral cavity
Lingual soft tissue and periosteum
Body of the mandibe, inferior portion of the ramus
Skin over the zygoma, posterior portion of the cheek, and temporal regions
Target area of gow gates
Lateral side of the condylar neck, just below the insertion of the lateral pterygoid muscle
Gow gates landmark
Extraoral
-the intertragic notch (lower border of the tragus). The correct landmark is the center of the external auditory meatus, which is concealed by the tragus
Intraoral
- height of injection established by placement of the needle tip just below the mesiolingual cusp of the maxillary second molar
- penetration of soft tissues just distal to the maxillary second molar at the height established in the preceding step
A closed mouth mandibular block technique that can be used in situations where limited mandibular opening precludes the use of other mandibular injections
Vazirani-akinosi closed mouth mandibular block
Nerves aneshesized of akinosi technique
Inferior alveolar nerve
Incisive nerve
Mental nerve
Lingual nerve
Mylohyoid nerve
Areas anesthetized of akinosi technique
Mandibular teeth to the midline
Body of the mandible and inferior portion of the ramus
Buccalmucoperiosteum and mucous membrane anterior to the mental foramen
Anterior 2/3 of the tongue and floor of the oral cavity
Lingual soft tissues and periosteum
Target area of akinosi
Soft tissue of the medial (lingual) border oft he ramus in the region of the inferior alveoar, lingual, and mylogoid nerves as they rnu inferiorly from the foramen ovale toward the mandibular formamen height of injection with the akinoi nerve block being below that of the gow-gates techniue but above of the IANB
Landmarks of akinosi
Mucogingival junction of the maxillary third molar
Maxillary tuberosity
Coronoid notch on the mandibular ramus
Areas anesthetized of mental nerve
Buccal mucous membranes anterior to the mental foramen (around the second premolar) to the midline and skin of the lower lip and chin
Nerves anesthetized of mental nerve
Mental nerve, a terminal branch of the inferior alveolar nerve
Target area of mental nerve block
Mentalnerve as it exits the mental foramen (usually located between the apices of the first and second premolars
Landmarks of mental nerve
Mandibular premolars and mucobuccal fold
Originating as a direct continuation of the IAN at the mental foramen, the ____ travels anteriorly in the incisive canal
Incisive nerve block
Nerves anesthetized by incisive nerve block
Mental and incisive nerves
Areas anesthetized by the incisive nerve b
Buccal mucos membrane anterior to the mental foramen, usually from the second premolar to the midline
Lower lip and skin of the chin
Pulpal nerve fibers to the premolars, canine and incisor
Recommended volume solution of inferior alveolar
1.5 mL
Target area of incisive nerve
Mental foramen, through which the mental nerve exits and inside of which the incisive nerve is located
Landmark of incisive nerve block
Mandibular premolars ad mucobuccal fold
