The mandibular canal is a conduit that allows the inferior alveolar neurovascular bundle to transverse the mandible to supply the dentition, jawbone and soft tissue around the lower lip. It is now acknowledged that the mandibular canal is not a single canal, but is an anatomical structure with multiple branches and variations. Iatrogenic injury to branches of the mandibular canal that carry a neurovascular bundle has been reported to cause injury as severe as to the main canal if traumatized. These injuries include bleeding, neurosensory disturbance or the formation of traumatic neuroma, and so far they involved cases with bifid mandibular canal. This current report presents a case of neurosensory disturbance that resulted from the impingement of a branch of a trifid mandibular canal during implant insertion. Its management included analgesics, reexamination and reinserting a shorter implant.
