Branch of the infraorbital nerve arising at the infraorbital groove. It runs downwards and forward in the lateral wall of the sinus to supply the maxillary premolars.  

An incision made in the middle of the crest of an edentulous ridge.  

Treatment providing a microscopically roughened surface.  

Radiographic recording of the details within the structure of thin specimens at a high magnification. Also known as X‐ray micrography. “The technique of passing X‐rays through a thin metal section in contact with a fine‐grained photograph to obtain a radiograph which can be viewed at 50× to l00× to observe constituents and voids.” Technique of…

A microscopic organism; those of medical interest include bacteria, viruses, fungi, yeasts, and protozoa. An organism that can be seen only through a microscope. Microorganisms include bacteria, protozoa, algae, and fungi. Although viruses are not considered living organisms, they are sometimes classified as microorganisms. An organism which cannot be observed with the naked eye; e.…

Relative motion on a microscopic scale. It generally describes the relative motion between an implant and its osteotomy site during the initial healing period or relative motion between mechanical components of the implant stack.  

Microscopic movement of fluids or contaminants across a barrier or between chambers that cannot be observed without magnification. The microscopic seepage of oral fluids between the interface of the tooth and a dental restoration. Microleakage may lead to sensitivity or discoloration of the tooth. Caused by discrepancies between the coefficient of thermal expansion of the…

Fixation by mechanical interlocking of bone to micro‐irregularities at textured dental implant surfaces, including those created by grit blasting, coating, or ion bombardment, which have dimensions in the range of less than 10 microns.  

Abnormal smallness of the jaw, particularly the mandible, that can be congenital or acquired. A condition in which one jaw is unusually smaller than the other. Marked undergrowth of one jaw relative to the growth of the other. Abnormal smallness of jaws, especially the lower jaw. An unusually undersized lower jaw, referred to as micrognathia,…
