(y) INTERINCISAL ANGLE * U1 – L1 (Max. to Mand. Incisor) : 135 +/- 11 The interincisal angle measures the relative spatial position along the long axis of the most prominent (anteriorly positioned) maxillary and mandibular central incisors. It determines the degree of procumbency (labial inclination) of the incisors. The more labially inclined (proclined) the incisors are, the less the interincisal angle. The more lingually inclined (retroclined) the incisors are, the more the interincisal angle. • Class II division 1 cases usually have a smaller than average interincisal angle. • Class II division 2 cases usually have a larger than average interincisal angle due to the lingual inclination of the maxillary central incisors. #thichchinhhinh #DentalSharing
