Hold these teeth root up and crown down, as they are positioned in the mouth. Ideally, examine several extracted maxillary central and lateral incisors or tooth models as you read the following. TYPE TRAITS OF MAXILLARY INCISORS FROM THE LABIAL VIEW These traits are presented for each view of the tooth: facial, lingual, proximal (includes mesial and distal traits), and incisal.Ī. Other traits will be helpful when distinguishing right maxillary incisors from left maxillary incisors. Within this section, type traits are presented that distinguish maxillary central from lateral incisors. Holding a maxillary incisor, determine whether it is a central or a lateral and right or left.Select and separate maxillary incisors from a selection of all teeth on a bench top.If possible, repeat this on a model with one or more maxillary incisors missing. Assign a Universal number to maxillary incisors present in a mouth (or on a model) with complete dentition.Describe and identify the labial, lingual, mesial, distal, and incisal surfaces for all maxillary incisors.Describe the type traits that can be used to distinguish the permanent maxillary central from lateral incisor.This section is designed to prepare the learner to perform the following:
