Missing Lateral Incisor Agenesis: Aesthetic Challenges With Cuspids in the Lateral Positions
INTRODUCTION
Encountering a patient who has been treated orthodontically to rectify the absence of the maxillary lateral incisors presents a unique aesthetic and functional challenge. Maxillary lateral incisor agenesis (MLIA) is the most common congenitally missing-permanent-tooth condition in the maxillary anterior region and contributes to significant aesthetic compromise and potential functional instability. Statistically, 20% of all congenitally missing teeth are maxillary laterals, and females are affected more than males. In addition, agenesis of both maxillary lateral incisors is more common than agenesis of only one.
