How can the clinician correct the problem of hitting bone while administering the PSA injection?

The correct answer highlights the importance of proper syringe position during the administration of the posterior superior alveolar (PSA) injection. When a clinician hits bone during this injection, it often indicates that the needle is positioned too far away from the target area or is angled incorrectly. By adjusting the syringe position closer to the occlusal plane, the clinician aligns the needle more accurately with the anatomical landmarks of the maxilla, directly targeting the area where the PSA nerve is located.

This adjustment helps prevent the needle from contacting the bone prematurely, ensuring a more effective injection and better anesthesia. Proper anatomical understanding is critical, as the PSA nerve is located in the pterygopalatine fossa, and the needle needs to enter this area without excessive angulation or displacement.

Utilizing a different angle or changing the gauge will not necessarily address the fundamental issue of targeting the correct area with the needle. Additionally, injecting more anesthetic solution initially does not resolve the mechanical issue of hitting the bone during the procedure; it may instead lead to discomfort for the patient without providing the necessary anesthesia if the injection site is not optimal.
