How To Do a Supraperiosteal Infiltration
Tricks and Tips
Distraction techniques (eg, talking to the patient or having the patient hold someone else's hand) may help to reduce patient anxiety. Inject the local anesthetic solution slowly (30 to 60 seconds) to reduce the pain of injection. Upper molars with thick overlying bone are sometimes not adequately anesthetized with supraperiosteal infiltration alone. If so, do a posterior superior alveolar nerve block. Using a 25- or 27-gauge long (3-cm) needle, enter the mucobuccal fold over the second molar. Aim posteriorly, superiorly, and medially, toward the posterior wall of the maxillary tuberosity at the level of the root apices. Aspirate, and then inject 1 to 2 mL of anesthetic solution.
