Anodontics of the upper permanent lateral incisor are often a difficult case requiring the collaboration of the orthodontist and the prosthetist. This condition is transmitted by the autosomal dominant and occurs in 2% of the population. The abnormality is two-fold more common in women and about two-thirds of those affected have congenital lack of both lateral incisors. In half of the patients who have only a missing lateral incisor, the homologous tooth is deficient or has the shape of a stake. When patients want the tooth to be replaced or when the position of the existing teeth is not favorable to the chosen treatment plan, the replacement of the tooth should be discussed preliminary before starting the orthodontic treatment. In this case, the difficulty encountered by the orthodontist is to manipulate the position of the patient’s teeth and the adjacent alveoli until he obtains the best support for the final prosthetic treatment solution. The prosthetist faces the difficulty of solving the aesthetic and functional needs of the patient and of designing a prosthetic work with a reasonable longevity in accordance with the patient’s expectations. Prosthetic restoration should contribute to the containment of the final position of the teeth and provide stability and occlusive therapeutic function. Kinzer and Kokich described three options for replacing the missing upper lateral incisor: canine substitution, a prosthetic restoration with dental aggregation, and a single dental implant.
