Term
Infiltration-Maxillary
a) Dental plexus of the injected site.
b) At the height of the mucobuccal fold closest to the apex of the tooth to be anesthetized.
c) A bony ridge, or eminence, can usually be palpated in the maxillary teeth. This serves as a landmark for visualizing the long axis of tooth and locating the apex of the tooth for penetration site.
d) 27 or 25 guage short needle.
e) Align barrel of the syringe parallel to long axis of the tooth, following the contour of the maxilla.
f) 3-6mm
g) 0.6 ml (1/3 of a cartridge). |

Maxillary-PSA
a) Teeth anesthetized: maxillary molars except mesiobuccal root of first molar.
Periodontium/soft tissues: buccal to affected teeth.
b) At the height of mucobuccal fold, posterior to the zygomatic process of the maxilla and generally superior to the distobuccal root of the maxillary second molar.
c) Posterior to zygomatic process of maxilla and superior to distobuccal root of maxillary second molar.
d) 25 or 27 gauge usually a short needle is recommended.
e) Angle of the neddle insertions is upward (at a 45 degree angle to the occlusal plane of maxillary teeth), inward behind maxillary tuberosity (at a 45 degree angle to the midsagittal plane), and then must be advanced backward behind the posterior aspect of the maxilla. The barrel of the syringe must be angled downward from the occlusal table and outward from midsagittal plane.
f) 16mm (9mm from the hub of an average 25mm short needle. Can range form 10-16mm for anatomical variances.
g) 0.9ml-1.8ml (1/2 to 1 cartridge) after negative aspiration. |

Periodontium/soft tissues: facial to affected teeth.
b) At the height of the mucobuccal fold over the maxillary second premolar.
c) Mucobuccal fold over maxillary second premolar.
d) 27 or 25 gauge short needle.
e) Follow the contour of the maxilla.
f) 5-8mm
g) 0.9-1.2ml (1/2 -2/3 of a cartridge). |

Maxillary- ASA
a) Teeth anesthitized: canine, lateral, central.
Periodontium/soft tissues: facial to affected teeth.
b) The height of mucobuccal fold anterior of canine eminence.
c) Above apical area of canine at height of canine fossa.
d) 27 gauge short needle is most common.
e) Align barrel of the syringe parallel to the long axis of canine, follow the contour of the maxilla.
f) Based on location of apex of the tooth and usually within 3-6mm.
g) 0.9ml (1/2 of a cartridge).

d) 27 gauge short needle.
e) Perpendicular to palatal bone at the foramen, with the syringe barrel near the lower lip.

Periodontium/soft tissues: all peridontium, buccal mucosa premolars to midline, floor of mouth and 1/2 tongue in quadrant.
b) Slighlty lateral to the pterygomandibular raphe at a height that is 2 to 3 millimeters superior to the greatest concavity of the coronoid notch, and well medial of the internal oblique ridge.
c) Pterygomandibular raphe, the coronoid notch on the anterior border of the ramus of the mandible, and the internal oblique ridge on the medial surface of the mandible close to the molars and continuing posteriorly.
d) 25 gauge long needle.
e) The syringe barrel is positioned at the labial commisure over premolars on the contralateral side of the mouth. The barrel remains parallel to and above the occlusal plane of mandibular molars throughout injection.
