Bupivacaine is known for its long duration of action, which makes it particularly effective for extensive procedures like full arch implant surgery. This local anesthetic can provide pain relief for several hours post-procedure, which is advantageous in surgeries that may induce significant discomfort afterward.

The formulation of bupivacaine used in this scenario, combined with epinephrine, not only prolongs the anesthetic effect but also helps to minimize bleeding during surgery by constricting blood vessels. This makes it well-suited for the needs of implant surgeries, where maintaining a dry surgical field and extended pain relief are both critical.

In contrast, other anesthetics listed have shorter durations of action, which can lead to insufficient analgesia in the postoperative period, making bupivacaine the preferred choice for such extensive surgical interventions.
