INTRODUCTIONAgenesis of one or more permanent teeth is one of the most common developmental anomalies in human beings. It has a prevalence varying from 2.2% to 7.7%, depending on continent, gender, and race. Apart from the third molar, the mandibular second premolar is the most affected tooth (41.0%), followed by the maxillary lateral incisor (22.9%) and the maxillary second premolar (21.2%). Unilateral agenesis is more common than bilateral agenesis, with exception of the maxillary lateral incisor.Patients with missing teeth may experience a reduced masticatory function, an inadequate articulation, and an unfavorable facial appearance. This may affect their self‐esteem, communication behavior, and professional performance. The treatment of missing teeth, and especially of those in the anterior, maxillary region, therefore requires a thoughtful treatment strategy to achieve a durable and highly esthetic result.There are two main options for the treatment of congenitally missing maxillary lateral incisors. These include (1) orthodontic space closure with canine substitution and (2) orthodontic space opening with a prosthetic replacement of the missing tooth. The treatment of choice can be determined by several clinical features such as age, sagittal occlusion, facial profile, presence, or absence of crowding in both dental arches, and tooth morphology, or by patient‐related
