The PSAN bloc is a type of anesthetic injection used to numb the lower back teeth and jaw for dental procedures. It stands for Pterygomandibular, Superior alveolar, Anterior superior alveolar, and Nasopalatine.
The pterygomandibular injection targets the mandibular nerve to numb the lower teeth. The superior alveolar injection numbs the upper teeth. The anterior superior alveolar injection numbs the front upper teeth. Finally, the nasopalatine injection targets the incisive canal to numb the palate.
By combining these four injections into the PSAN bloc, the lower back teeth, upper teeth and palate can all be numbed at the same time. This allows the oral surgeon to work on multiple areas during a procedure without having to give separate numbing injections.
The PSAN bloc is useful for impacted wisdom tooth removal, dental implants or other treatments on the back teeth and palate. The four nerve sites are targeted with a dental syringe to deliver the numbing medication. Once injected, the anaesthetic takes effect quickly to numb the area for the dental work.
Does this help explain the PSAN bloc injection in simple terms? Let me know if you need any clarification or have additional questions!
