Regarding to current studies indicate a 2.2% incidence of missing lateral incisors, management of this condition is one of the important situation of  interdisciplinary treatment planning .Three treatment options exist for the replacement of congenitally missing lateral incisors: canine substitution, a tooth-supported restoration, or a single-tooth implant. Selecting the appropriate treatment option depends on the malocclusion, the anterior relationship, specific space requirements, and the condition of the adjacent teeth. The ideal treatment is the most conservative alternative that satisfies individual esthetic and functional requirements
Often the ideal option is canine substitution. The general dentist will learn to evaluate specific patient selection criteria and determine whether canine substitution is an appropriate treatment alternative for replacing missing lateral incisors. The orthodontist will understand how to position the canines to satisfy functional requirements and achieve proper esthetics. Although the orthodontist positions the canine in the most esthetic and functional location, the restorative dentist often needs to place a porcelain veneer or crown to re-create normal lateral incisor shape and color.
Three options when replacing a missing lateral incisor with a tooth-supported restoration are a resin-bonded fixed partial denture, a cantilevered fixed partial denture, and a conventional full-coverage fixed partial denture. The specific criteria that must be evaluated for each option is addressed to illustrate the importance of interdisciplinary treatment planning to achieve optimal esthetics and long-term predictability.
Today, the single–tooth implant has become one of the most common treatment alternatives for the replacement of missing teeth. When treatment planning single-tooth implant to replace congenitally missing lateral incisors ,an interdisciplinary approach is necessary to provide the most predictable treatment outcome.
