Fig. 2: Line of intermediate smile. The smile uncovers the papillae and reaches the collar of the incisors (12 and 22 are supported by implants). Fig. 3a: Average forms, types and dimensions of the lateral incisor according to Papathanassiou.6 Overall height: 21 mm, coronal height: 9 mm, radical height: 12 mm, mesiodistal cervical diameter: 5 mm, mesio- distal coronal diameter: 6.5 mm, vestibular-lingual cervical diameter: 5 mm, vestibular-lingual coronal diameter: 6.5 mm. Fig. 3b: Proximal view photographs showing ten anatomical variants of lateral maxillary incisors described by the author.6 Introduction Faced by a missing lateral incisor, practitioners often consider a wide range of issues and are also faced by numerous treatment options: –– in a young patient, faced with a unilateral or bilateral agenesis, he has to choose between an orthodontic treatment that either opens up the spaces or closes them. This decision, when taken early in the overall treatment, will affect both the patient and their caregiver for a long time (Fig. 1); –– in an adult patient, this is a consequence of bone, physiological, traumatic or infectious resorption, which will result in a decision whether or not to recommend a bone recon struction or a gingival augmentation. In every situation, the results will be judged by the patient and those around him. Since the lateral maxillary incisor is an integral part of the smile, aesthetic expectations are generally very high and, if the results do not meet the expectations, dis appointment can be powerfully felt.
