Relating to the cutting edge of an anterior tooth (incisor or canine). The incisal edge is the biting edge of an incisor or canine. The incisal angle is the angle between the incisal edge and the mesial or distal surface of an anterior tooth. The incisal guide table forms the base for the incisal guide pin on an articulator. Incisal guidance is the influence on mandibular movements caused by the contacting surfaces of the mandibular and maxillary anterior teeth during masticatory movements (eccentric excursions from centric occlusion).
