| 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) |

| Broca's visual plane | A plane drawn through the visual axes of each eye. (05 Mar 2000) |
| Camper's plane | A plane running from the tip of the anterior nasal spine (acanthion) to the centre of the bony external auditory meatus on the right and left sides. (05 Mar 2000) |
| canthomeatal plane | Plane passing through the two lateral angles of the eye and the centre of the external acoustic meatus; this plane lies approximately midway between the Frankfort and the supraorbitomeatal plane's. (05 Mar 2000) |
| parasagittal plane | Any plane parallel to the mid-sagittal plane or anteroposterior median plane. See: sagittal plane. (05 Mar 2000) |
