lateral incisal guide angle

lateral incisal guide angle,

the inclination of the incisal guide of a dental articulator in the frontal plane.

---

angle,

n the degree of divergence of two or more lines or planes that meet each other; the space between such lines. Measured in degrees of an arc.

angle, bayonet former,

n a hoe-shaped, paired cutting instrument; biangled with the blade parallel with the axis of the shaft. The cutting edge is not perpendicular to the axis of the blade. Used to accentuate angles in an “invisible” class 3 cavity.

angle, Bennett,

n the angle formed by the sagittal plane and the path of the advancing condyle during lateral mandibular movement, as viewed in the horizontal plane.

angle board,

n a device used to facilitate the establishment of reproducible angular relationships between a patient's head, the radiographic beam, and the radiograph film.

angle, cavosurface

n the angle in a prepared cavity, formed by the junction of the wall of the cavity with the surface of the tooth.

angle, contact,

n the angle at which a liquid or vapor meets a solid surface; e.g., the angle at which a droplet of water rests on an oily surface.

angle, cranial base,

n the angle formed by a line representing the floor of the anterior cranial fossa intersecting a line representing the axis of the clivus of the base of the skull.

angle, cusp,

n 1. the angle made by the slopes of a cusp with the plane that passes through the tip of the cusp and is perpendicular to a line bisecting the cusp; measured mesiodistally or buccolingually. Half of the included angle between the buccolingual or mesiodistal cusp inclines.
n 2. the angle made by the slopes of a cusp with a perpendicular line bisecting the cusp; measured mesiodistally or buccolingually.

angle, facial,

n an anthropometric expression of the degree of protrusion of the lower face, assessed by measuring the inclination of the facial plane relative to a horizontal reference plane.

angle, former,

n a paired, hoe-shaped cutting instrument that has the cutting edge at an angle other than a right angle in relation to the axis of the blade.

angle, Frankfort-mandibular incisor (FMIA)

n a measure of the mandibular incisor to the Frankfort horizontal plane.

n the degree of slope between the axis-orbital plane and the palatal discluding skidway of the maxillary incisor.

angle, incisal guidance,

n the angle formed with the occlusal plane by drawing a line in the sagittal plane between the incisal edges of the maxillary and mandibular central incisors when the teeth are in centric occlusion.

angle, incisal guide,

n the inclination of the incisal guide on the articulator.

angle, lateral incisal guide,

n the inclination of the incisal guide in the frontal plane.

angle, line,

n an angle formed by the junction of the two walls along a line; designated by combining the names of the walls forming the angle.

angle, occlusal rest,

n the angle formed by the occlusal rest with the upright minor connector.

angle of mandible,

n an angle at the intersection of the posterior and inferior borders of the ramus.

angle, point,

n an angle formed by the junction of three walls at a common point; designated by combining the names of the walls forming the angle.

angle, prophylaxis

n the term for an angled instrument that holds a rubber cup or bristle brush used to polish teeth. It may be either contra- or right-angled. May also be called a
prophy angle.

angle, protrusive incisional guide,

n the inclination of the incisal guide in the sagittal plane.

angle, rest,

n See angle, occlusal rest.

angle, symphyseal

n the angle of the chin, which may be protruding straight or receding, according to type.
