| tempero-mandibular joint | The TMJ hinges the lower jaw (mandible) to the skull. (12 Dec 1998) |
|---|---|
| tempero-mandibular joint syndrome | <syndrome> Disorder of the temporo-mandibular joint(s) causing pain usually in front of the ear(s). Pain in the tmj can be due to trauma (such as a blow to the face), inflammatory or degenerative arthritis, or by the mandible being pushed back towards the ears whenever the patient chews or swallows. Sometimes, muscles around the tmj used for chewing can go into spasm, causing head and neck pain and difficulty opening the mouth normally. (12 Dec 1998) |
| joint, tempero-mandibular | Joint that hinges the lower jaw (mandible) to the skull. Abbreviated tmj or tm joint. (12 Dec 1998) |
| free mandibular movements | Any mandibular movement's made without tooth interference, any uninhibited movement's of the mandible. (05 Mar 2000) |
| functional mandibular movements | All natural, proper, or characteristic movement's of the mandible made during speech, mastication, yawning, swallowing, and other associated movement's. (05 Mar 2000) |
| Aeby's plane | In craniometry, a plane perpendicular to the median plane of the cranium, cutting the nasion and the basion. (05 Mar 2000) |
| aperture plane | <microscopy> In a microscope adjusted for Koehler illumination, the conjugate planes that include the light source, the condenser iris diaphragm, the objective lens back aperture, and the eye point. Spaces in the aperture planes are the reciprocal of those in the field planes. (05 Aug 1998) |
| auriculo-infraorbital plane | A standard craniometric reference plane passing through the right and left porion and the left orbitale; drawn on the profile radiograph or photograph from the superior margin of the acoustic meatus to the orbitale. Synonym: auriculo-infraorbital plane, eye-ear plane, Frankfort horizontal plane, Frankfort plane, infraorbitomeatal plane. (05 Mar 2000) |
| axial plane | Transverse plane, as in CT scanning. Synonym: transaxial plane. (05 Mar 2000) |
| axiolabiolingual plane | A plane parallel to the long axis of a tooth and extending in a labiolingual direction. (05 Mar 2000) |
| axiomesiodistal plane | A plane parallel to the long axes of the teeth and extending in a mesiodistal direction. (05 Mar 2000) |
| back focal plane | <microscopy> The plane, normal to the lens axis, situated at the back focus of a lens. (05 Aug 1998) |
| bite plane | <dentistry> A removable appliance made of acrylic designed to open a deep bite. See: occlusal plane. (06 Mar 2000) |
| Bolton-Broadbent plane | A roentgenographic cephalometric plane extending from the Bolton point to nasion. Synonym: Bolton-Broadbent plane, Bolton-nasion line, Bolton-nasion plane. (05 Mar 2000) |
| Bolton-nasion plane | A roentgenographic cephalometric plane extending from the Bolton point to nasion. Synonym: Bolton-Broadbent plane, Bolton-nasion line, Bolton-nasion plane. (05 Mar 2000) |
