“…In the case of mandibular third molars, inferior alveolar nerve (IAN) damage could result in paresthesia or impairment of perception, including dysesthesia and/or anesthesia of the teeth, lip, and chin . The incidence of permanent damage to the IAN is consistently reported in the literature to occur in less than 1% of all cases . However, the incidence of temporary damage is less consistent, ranging from 26% to 13% of all cases .…”

“…Further, CBCT revealed a buccolingual relation of IAN with the roots of M3 avoiding compression injuries to the nerve 16 . However, till date, there is no evidence in the literature demonstrating any significant decrease in the occurrence of IAN injury resulting from pre-operative 3D-imaging 17 . Therefore, although 2D panoramic radiograph suffices for most cases of M3 surgery, CBCT is required whenever there is a radiographic sign of proximity of roots to the mandibular canal.…”

IntroductionSurgical removal of mandibular third molars is the most common proce-dure performed by oral and maxillofacial surgeons. Innovations in radiographic imaging are useful in pre-operative planning and advances in surgical tools and medical therapies are reducing postoperative morbidities. This article provides a review of the available data on the importance of preoperative assessment and means of decreasing post-operative complications.

“…This might correspond to a substitution of the diagnostic method but without optimizing its use. Using CT scans does not significantly decreases the risk for producing an injury to the IAN [37]. Nevertheless, CT use permits the clinician to identify possible individual anatomical variants and to successfully plan cases for implants avoiding damaging important anatomical structures among them, the nerves (Figure 6 and 7).…”

The inferior alveolar nerve (IAN) is one of the most important structures in dentistry. It is a terminal branch that originates from the mandibular root of the trigeminal nerve. This branch courses through the inner aspect of the mandible and innervates teeth and some muscles as the mylohyoid or digastric ones and the gums or lips by its mental branch.Although the main cause of IAN lesion occurs during third molars extractions, IAN can be injured during implant surgery, especially in cases with an atrophic posterior mandible. It is difficult to sever the nerve due to its large caliber. On the contrary, nerve compression or laceration constitute more common complications.Diverse preventive methods to avoid IAN injury have been reported such as using a precise diagnostic procedure as computerized tomography (CT), guided implant surgery, or placing short implants.We may classify nerve injury effects ranging from a light tingling (dysesthesia) to temporary or permanent loss of sensibility (hypoesthesia) or to increased sensibility. These cases require a careful management as these events may increase the patients' and dental practitioners' anxiety. When the IAN has not been totally interrupted, healing occurs in the next 3 to 6 month even spontaneously.Sometimes we can alleviate patients giving them some painkillers or vitamin complexes to minimize symptoms or to improve healing. The use and utility of this kind of treatment is controversial however we should not underestimate its placebo effects.
