Techniques of Mandibular Anesthesia
 Mandibular Anesthesia
  • Lower success rate than Maxillary anesthesia – approx. 80-85 %
  • Related to bone density
  • Less access to nerve trunks
Mandibular Nerve Blocks
  • Inferior alveolar
  • Mental – Incisive
  • Buccal
  • Lingual
  • Gow-Gates
  • Akinosi
Mandibular Anesthesia
  • Most commonly performed technique
  • Has highest failure rate (15-20%)
  • Success depends on depositing solution within 1 mm of nerve trunk
Inferior Alveolar Nerve Block
  • Not a complete mandibular nerve block.
  • Requires supplemental buccal nerve block
  • May require infiltration of incisors or mesial root of first molar
Nerves anesthetized
  •     Inferior Alveolar
  •     Mental
  •     Incisive
  •     Lingual
Areas Anesthetized
  •     Mandibular teeth to midline
  •     Body of mandible, inferior ramus
  •     Buccal mucosa anterior to mental foramen
  •     Anterior 2/3 tongue & floor of mouth
  •     Lingual soft tissue and periosteum
Indications
  •     Multiple mandibular teeth
  •     Buccal anterior soft tissue
  •     Lingual anesthesia
Contraindications
  •     Infection/inflammation at injection site
  •     Patients at risk for self injury (eg. children)
Alternatives
  •     Mental nerve block
  •     Incisive nerve block
  •     Anterior infiltration
  •     Periodontal ligament injection (PDL)
  •     Gow-Gates
  •     Akinosi
  •     Intraseptal

Technique
    Apply topical
    Area of insertion:
  •         medial ramus, mid-coronoid notch,
  •         level with occlusal plane (1 cm above),
  •         3/4 posterior from coronoid notch to pterygomandibular raphe
  •         advance to bone (20-25 mm)
Target Area
  •     Inferior alveolar nerve, near mandibular foramen
Landmarks
  •     Coronoid notch
  •     Pterygomandibular raphe
  •     Occlusal plane of mandibular posteriors
Precautions
  •     Do not inject if bone not contacted
  •     Avoid forceful bone contact
Failure of Anesthesia
  •     Injection too low
  •     Injection too anterior
  •     Accessory innervation
    •    Mylohyoid nerve
    •    contralateral Incisive nerve innervation
Complications
  •     Hematoma
  •     Trismus
  •     Facial paralysis
