[Begg mechanics in treatment of congenitally missing lateral incisor]

The maxillary lateral incisors are the most frequently missing teeth after the third molars. The cases with congenitally missing lateral incisors are treated either by orthodontically closing the spaces or by space regaining for prosthetic restorations. Malocclusion is the most effective factor for selecting the treatment method. Besides the characteristics of the malocclusion and interdigitation, the colour, the shape, the size and the position of the canines effect the treatment planning. In particular, Class II Div. 1 and Cl. I anterior crowding cases are the most convenient cases for orthodontically closing the missing lateral spaces. In these cases besides the treatment of the present malocclusion the reshaping of the canines is aimed and these teeth are moved to lateral spaces. In this article the treatment of a Cl. II Div. 1 malocclusion case with congenitally maxillary missing lateral incisor with Begg technique will be presented. The changes and variations of the Begg mechanics applied for this case will be discussed.
