The prevalence of congenitally missing teeth has been studied and reported by many Authors: a presence ranging between 6 to 10% was found in the population, with a prevalence of congenitally missing upper lateral incisors (CMLI) between 1 and 2%. Furthermore, it has been found that agenesis of both maxillary lateral incisors is more common than the single one. Patients with congenitally missing maxillary lateral incisors (CMLI) often need challenging interdisciplinary treatment and the replacement of CMLI offers three treatment options: canine substitution, tooth-supported restorations, or single implants. The ideal treatment must fulfill individual esthetics, functional requirements and periodontal health: not only at the end of the treatment, but also in the long-term. The rationale, effectiveness and advantage for space closure treatment have been widely discussed in previous articles, and this treatment finds its greatest application since CMLI is usually diagnosed at young age. Space closure offers indeed the possibility of completing treatment before adolescence and achieving a long-term stable outcome at a young age. Hence, it is possible to avoid a long lasting period with temporary restorations waiting for the final restorative procedures at the end of growth. Long-term investigations on periodontal, functional and esthetic stability have shown that space closure can lead ......
