  • Inclined plane of a tooth

    Any sloping surface of the cusp of a tooth.  

  • Inclined plane of the pelvis

    Anterior and posterior inclined planes of the pelvic cavity, two unequal sections divided by the sciatic spines. In the larger, anterior section, the lateral walls slope toward the symphysis and arch of the pubes; the posterior walls slope in the direction of the sacrum and coccyx.

    One of two planes through the anterior and posterior principal foci of a dioptric system and perpendicular to the line connecting the two. Within the field of tomography, there is a significant concept known as the “area of interest.” This refers to the specific region of the body that becomes the focal point and appears…

  • Datum plane

    An assumed horizontal plane from which craniometric measurements are taken.  

  • Axiomesiodistal plane

    A plane that passes through a tooth parallel to the axis and in a mesiodistal direction.  

  • Axiolabiolingual plane

    A plane that passes through an incisor or canine tooth parallel to the long axis of the tooth and in a labiolingual direction.  

  • Alveolocondylar plane

    A plane tangent to the alveolar point with most prominent points on lower aspects of condyles of the occipital bone.  

  • Planchet

    A small, flat container or dish on which a radioactive sample is placed.  

  • Care plan
