Esthetics as well as occlusion must be considered in the final orthodontic positioning of the teeth adjacent to the edentulous space. To satisfy the “golden proportion” principle of esthetics, the space for the maxillary lateral incisor should be approximately two-thirds of the width of the central incisor. However, if the patient is missing only one maxillary lateral incisor, the space required to achieve symmetrical esthetics and occlusion is primarily dictated by the width of the contralateral incisor. When both laterals are congenitally absent, the occlusion may influence the amount of space required for the implant restoration and the proportional relationship between the central and lateral incisors.
