REVIEW OF THE AMSA INJECTION TECHNIQUE
1. Prepare the patient for a slow injection experience.
2. Place topical anesthetic on the palatal tissue if desired.
3. Orient a 30 gauge extra-short needle, bevel parallel to the palatal tissue at
the landmark which bisects the premolars and is midway between the free
gingival margin and the mid palatine suture.
4. Place a sterile cotton tip applicator to absorb any anesthetic drip prior to
needle penetration.
5. Perform pre-puncture technique.
6. Rotate needle slightly upon entering tissue and during movement to final
site.
7. Initiate the slow flow rate at the moment that the needle enters the palatal
tissue and maintain this rate continuously. Reorient needle to 45º and
advance the needle very slowly until it contacts bone.
8. Perform aspiration.
9. Cruise control can be activated if desired.
10. Continue to inject until approx. 3/4 to 1 full cartridge has been deposited.
11. Remove the needle slowly and try to avoid any excess anesthetic
dripping.
12. Repeat on the contralateral side if required.
