The alveolar nerve inferior, which is also called the inferior dental nerve, plays an important role in implant dentistry. It is a part of the mandibular nerve and supplies sensation to the lower teeth, lower lip, and chin. There are two critical factors when considering the alveolar nerve during a dental implant procedure. The treating physician must ensure that the nerve is sufficiently numbed so the implant procedure isn’t painful for the patient, and that the nerve is not injured as the buccal flap is made and the implant is placed. An inferior alveolar nerve block can help numb the teeth, lower lip, chin, and the front 2/3 of the tongue. The posterior superior alveolar nerve must be avoided during surgery to prevent permanent loss of sensation or chronic pain. Injuries to the alveolar nerve are risky, because they may or may not resolve. Chronic pain or loss of sensation may result in implant failure.
