–local infiltration or nerve block
–near terminal nerve endings
–varying degrees of success
–agent deposited near large nerve trunks
–higher degree of success than infiltration
Injection site: height of mucobuccal fold at apex of maxillary first premolar
injection site: in palatal tissue anterior to depression of GP foramen; midway between medial palatine raphe and lingual gingival margin of maxillary molar
injection site: lingual/palatal tissue lateral to incisive papilla, 10 mm lingual to maxillary central incisor;
–never directly into incisive papilla!
–needle 45 degree angle to palate
injection site: area biscecting the apices of maxillary premolars, and midway between median palatal raphe and lingual ginginval margin
–45 degree angle from contralateral premolars; maxilla contacted
Injection site: mandibular tissue on medial border of ramus; palpated at depth of pterygomandibular space on medial surface of ramus
injection site: buccal tissue distal and buccal to the most distal mandibular molar in mandibular arch
–advance needle until it contacts mandible and then inject
anterior to depression created by mental foramen at depth of mucobuccal fold with needle horizontal and resting on lower lip, without contacting mandible; between apices of premolars
insertion site: anterior to depression created by mental foramen at depth of mucobuccal fold with needle horizontal and resting on lower lip, without contacting mandible; between apices of premolars
injection site: intraorally on oral mucosa on mesal of mandibular ramus; just distal to height of mesiolingual cusp of maxillary 2nd molar with direction determined by following a line extraorally from intertragic notch to ipsilateral labial commisure
The effectiveness of local anesthetic agents is greatly reduced when administered adjacent to areas of infection, so additional amounts of local anesthetic agent may be needed keeping the maximal recommended dosage always in mind for each patient.
PSA: up, in, back at 45 degrees each way
–at depth of mucobuccal fold anterior to the depression created by mental foramen, WITHOUT contacting mandible!
–buccal only gets buccal gingiva of molars
