An azalide antibiotic which inhibits bacterial protein synthesis, and is effective against a wide range of gram‐positive, gram‐negative, and anaerobic bacteria. It is used in the treatment of mild to moderate infections caused by susceptible organisms, and may be administered orally and intravenously. Once-daily antibiotic agent used in respiratory infections and in skin infections; similar…

New generation of macrolide derivatives with improved pharmacokinetic properties, tissue penetration, and activity against many gram‐positive and gram‐negative bacteria. A derivative of the macrolide antibiotics, modified by the addition of nitrogen to the macrolide (“large ring”) structure. An example is azithromycin.  

Nerve injury with loss of axonal continuity, but with maintenance of the myelin sheath. Sensory and/or motor functions are impaired. Recovery may occur after 1–3 months. It may be caused by a drill violating the mandibular canal, an anesthetic needle penetrating the nerve trunk, or excessive reflection. Nerve injury that damages the nerve tissue without…

The horizontal imaginary line or plane determined by the transverse horizontal axis of the mandible as it correlates with the palpated lowermost point found at the inferior margin of either the left or right bony orbit (orbitale). This plane is used as a horizontal orientation point to position teeth and/or dental implants in the ideal…

The prepared or intended path of insertion and removal for a dental restoration as it relates to its axial surface.  

A real or imaginary straight line passing through the center of a body, such as the mandible. Long axis of a tooth the central lengthwise line through the crown and the root. A real or imaginary straight line around which a body may rotate. Main line of development of a plant or organ; (Of inflorescence)…

The side of a body that is in its long axis. In dentistry, the surface of a tooth preparation that is in its long axis.  

The exterior of a body that is oriented in its long axis.  

A thin section from computed tomography scan data (usually 0.125–2.0 millimeters thick) transverse to the patient’s length axis, ideally parallel to the plane of occlusion.  

Removal of tooth structure or its prosthetic equivalent (i.e., implant abutment) along its ideal long axis. The location and amount of reduction depend on the reason for altering or preparing. Compare: Incisal reduction, Occlusion reduction.
