a brief for local anesthesia techniques in dentistry; practical for after perusing the techniques before. Used reference was MALAMED handbook of oral anesthesia.
5. Posterior Superior Alveolar Nerve
Block
â– High success rate
â– Risk of hematoma
â– Technique somewhat arbitrary: no bony landmarks during insertion
â– Second injection necessary for treatment of the first molar (mesiobuccal root) in 28% of
patients

9. Middle Superior Alveolar Nerve Block
â– Indicated for procedures on premolars and for the mesiobuccal root of the maxillary first
molar.
â– Contraindicated Where the MSA nerve is absent, innervation is through the anterior
superior alveolar (ASA) nerve; branches of the ASA innervating the premolars and
mesiobuccal root of the first molar can be anesthetized by means of the MSA technique
â– the mucobuccal fold above the second premolar
â– No bone touch.

12. Anterior Superior Alveolar Nerve Block
(Infraorbital Nerve Block)
â– Nerves Anesthetized
â– 1. Anterior superior alveolar
â– 2. Middle superior alveolar
â– 3. Infraorbital nerve
– a. Inferior palpebral
– b. Lateral nasal
– c. Superior labial
13. Anterior Superior Alveolar Nerve Block
(Infraorbital Nerve Block)
â– Inflammation or infection (which contraindicates supraperiosteal injection); if a
cellulitis is present, the maxillary nerve block may be indicated in lieu of the
infraorbital nerve block (indicated)
â– Discrete treatment areas (Contra-indicated)
â– Ant to 1st pre.
â– Almost the half of L- needle.
24. INFERIOR ALVEOLAR NERVE
BLOCK
â– Landmarks
– a. Coronoid notch (greatest concavity on the anterior border of the ramus)
– b. Pterygomandibular raphe
– c. Occlusal plane of the mandibular posterior teeth
– 2/3 & 3/4
29. â– Height of injection established by placement of the needle tip just below the
mesiolingual (mesiopalatal) cusp of the maxillary second molar
â– Penetration: just distal to the maxillary second molar
35. INCISIVE NERVE BLOCK
â– bilateral incisive nerve blocks can be administered.
â– It is not necessary [also not indicated; according to the text] for the needle to
enter into the mental foramen for an incisive nerve block to be successful.
