Nerve Names
This nerve is targeted during a PSA injection.
What is the posterior superior alveolar nerve?
This bony structure serves as a landmark for a greater palatine injection.
What is the greater palatine foramen?
For the ASA injection, the needle is inserted at this angle.
What is approximately 10 degrees to the long axis of the canine?
This hematoma is most likely from which maxillary injection?
What is the PSA?
Your patient complains of burning during injection, and blanching occurs. What likely happened?
what is too rapid of an injection or a vasoconstrictor near a blood vessel?
Maxillary premolars and mesiobuccal root of maxillary 1st molar
What is Middle Superior Alveolar Nerve?
The height of mucobuccal fold above maxillary 2nd premolar, 1/4 (5mm) length of short needle.
What is the MSA injection?
After administering an ASA injection, the patient still feels discomfort during instrumentation.
What is incomplete anesthesia?
Apply pressure, reassure patient, document, and monitor.
What is a Hematoma?
Your patient reports feeling numb in the upper lip but not in the teeth after the ASA injection.
What is incomplete anesthesia? Needle placement may have been too shallow.
Insert the needle directly over the first maxillary premolar.
What is the Infraorbital Nerve Block?
This bony structure serves as a landmark for a Nasopalatine injection.
What is the Incisive foramen?
Insert at mucobuccal fold above 2nd premolar. Advance well above apices of bicuspid teeth
What is MSA?
Remain calm, try to retrieve if visible, and refer for surgical removal if necessary. Avoid bending needles or inserting them to hub.
What is a needle breakage?
After a GP injection, the patient experiences difficulty swallowing.
What is diffused anesthetic to the soft palate or pharyngeal area?
Anesthetizes: soft tissue overlying the hard palate; bone posterior to the first premolar to the midline
What is the Greater Palatine Nerve Block?
The ASA injection site.
What is the mesial aspect of the canine tooth eminence, at the height of the mucobuccal fold?
Withdraw slightly, change needle and cartridge, reattempt with correct angulation to avoid vascular penetration.
What is a positive aspiration?
Presence of large buccal frenum at site, pain on insertion with needle against periosteum, and dense bone
What is MSA complications?
Patient has swelling and bruising 10 minutes after injection.
What is documenting, applying pressure, and monitoring?
Potentially the most traumatic
What is the Nasopalatine Nerve Block (NP)?
The height of the mucobuccal fold just mesial to canine eminence. Parallel to long axis at 10-15 degree angle; 1/4 (5mm) length of short needle.
What is the ASA injection?
Mucobuccal fold just Mesial to canine eminence; parallel to the long axis and at the apex of the canine (10-degree angle). Insertion: 1/4 length of needle
What is Anterior Superior Alveolar nerve?
Pull the lip out and down to allow for deeper insertion.
What is encounter bone?
Handle a patient who complains of burning during the injection.
What is slow the rate of deposition, and ensure the solution is at room temperature?
