BACKGROUND One option for successful placement of dental implants in an atrophic posterior mandible without injury to the inferior alveolar nerve (IAN) is to transpose or lateralize the nerve. This procedure carries the risk of numbness along the distribution of the nerve, the complication that the procedure is undertaken to avoid in the first place. The purpose of the present study was to assess mental nerve function after transposition of the IAN. METHODS We determined the outcomes of 20 IAN transposition procedures in 12 consecutive patients at the Queen Elizabeth II Health Sciences Centre in Halifax, Nova Scotia. The study included objective testing of sensory nerve function as well as subjective assessment by the participants. RESULTS All subjects reported initial transient sensory disturbance. Objective testing after a minimum of 6 months revealed that, for each patient, affected sites had the same level of sensation as unoperated areas. Eighty percent of the patients said that the lower lip and chin felt normal. The others said that these structures did not feel exactly normal but that the difference was of no consequence. CONCLUSIONS It is concluded that IAN transposition can be safely and predictably performed with low risk to the mental nerve sensibility.

D008340	Mandibular Nerve	A branch of the trigeminal (5th cranial) nerve. The mandibular nerve carries motor fibers to the muscles of mastication and sensory fibers to the teeth and gingivae, the face in the region of the mandible, and parts of the dura.

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

D020886	Somatosensory Disorders	Disorders of sensory information received from superficial and deep regions of the body. The somatosensory system conveys neural impulses which pertain to proprioception, tactile sensation, thermal sensation, pressure sensation, and pain. PERIPHERAL NERVOUS SYSTEM DISEASES; SPINAL CORD DISEASES; and BRAIN DISEASES may be associated with impaired or abnormal somatic sensation.
