Today, technologies exist that allow for complete pain and anxiety control.
Many patients claim that the most uncomfortable part of anesthesia is the needle insertion, while most of the pain is caused by the speed and pressure with which the anesthetic is injected.
A brand-new computerized anesthetic administration technique now exists, replacing the 150-year-old hypodermic syringe technology. It consists of a computer-controlled local anesthetic dispenser that monitors the anesthetic's output pressure in real time at every stage of administration and ensures the needle is maintained in optimal position throughout the injection.
The anesthesia will be be faster and deeper, but above all less or not at all painful, because it is performed below the patient's pain threshold. Furthermore, the ability to anesthetize a single tooth eliminates the annoying sensation of numbness in the lips. The anxiety that often accompanies surgical treatments can easily be controlled with conscious sedation. This is a technique that achieves an intermediate state between wakefulness and sleep by administering hypnotic-sedative drugs that act on the central nervous system. An important feature of this technique is the maintenance of consciousness, with the patient's ability to respond verbally and cooperate with the oral surgeon. Thanks to it, the autonomous maintenance of the patency of the airways and of the swallowing and cough reflexes is also achieved.

Neuromuscular relaxation combined with mild analgesia maintains adequate sedation with very low risk to the patient, whose vital signs will be monitored both clinically and instrumentally. This technique also reduces auditory and visual stimuli associated with the administration of effective local anesthesia.

The advantage of sedating a patient who remains conscious and has airway protective reflexes and anterograde amnesia in oral surgery is extremely beneficial. Complications primarily concern side effects of the drugs administered, while potential risks include respiratory depression, aspiration of gastric contents, cardiac complications, and allergic reactions. However, these complications are rare and generally well managed.
