  • Neuralgia

    Neurogenous pain felt along the peripheral distribution of a nerve trunk. Is a sudden, severe painful disorder of the nerves. Pain caused by nerve irritation or damage. Pain in and originating along nerve fibers. Pain occurring in the area served by a sensory nerve. Pain resulting from irritation or inflammation of a nerve. Severe pain…

  • Nerve repositioning (syn)

    Nerve lateralization, nerve transpositioning. Surgical procedure whereby the course of the inferior alveolar nerve is redirected to allow the placement of longer implants in a mandible with extensive resorption of the posterior ridge.  

  • Nerve lateralization

    Surgical procedure that repositions the inferior alveolar nerve for the purpose of implant placement without bone augmentation. The buccal cortex surrounding the mandibular canal is removed to allow the repositioning of the nerve. This procedure raises the risk of neuropathies, such as para‐, dys‐, and/or anesthesia of the inferior alveolar nerve. Because of the high…

  • Neoplasm

    Neoplasm

    A new, abnormal, uncontrolled growth arising from a given tissue. If malignant, can have the capacity to metastasize locally or systemically. When malignant, the disease entity is generically known as cancer. Tumour; any new and abnormal growth, specifically one in which cell multiplication is uncontrolled and progressive. Neoplasms may be benign or malignant. Abnormal formation…

  • Neisseria spp

    Gram‐negative, nonmotile, microaerophilic cocci found as part of the indigenous oral flora.  

  • Negative predictive value

    The proportion of negative responses to a diagnostic test for a disease that are accurate indicators of the true absence of the malady in a population. Expressed arithmetically as a proportion which is calculated as the number of true‐negative responses divided by the sum of true‐negative responses plus false‐negative responses, i.e., negative predictive value =…

  • Nd: YAG laser (abbrev)

    Neodymium‐doped yttrium aluminum garnet laser. A solid‐state laser containing a Nd:YAG crystal which emits at a wavelength of 1064 nanometers. It is mainly used in soft tissue surgery.  

  • Ncm (abbrev)

    Newton centimeters.  

  • Navigation surgery (syn)

    Computer‐aided navigation, implant‐guided surgery, navigation, surgical navigation. A surgical modality in which the intraoperative localization of the surgical instrument is fed back visually onscreen in reference to the preoperative diagnostic imaging of the patient by employing patient registration algorithms and motion tracking technology. In implant dentistry, the implant drilling and placement are guided by imaging…

  • Natural tooth intrusion

    Apical movement of a tooth produced by an external force. Phenomenon reported in literature as being a complication of connecting a natural tooth to a dental implant with a fixed prosthesis.
