Abstract

Anterior crossbite is a common strike anomaly that may be found in growing patient who is seeking orthodontic treatment
for functional reason. On the other hand, impacted t ooth is a failure of dental eruption which is sometimes not realized by
patient until having proper dental examination. The following case report described an orthodontic treatment of 10-yearold girl with straight profile and impacted maxillary left second premolars. This condition associated with arch length
discrepancy causing space deficiency for second premolars eruption. The management of correcting anterior crossbite
concurrently maxillary second premolars impaction started with space regaining by eliminate occlusal interference prior
to distal movement of the posterior teeth. The most significant drawback of distalization is an equal and opposite mesial
force tends to flare the incisors labially. After 12-months of treatment, distal movement of posterior teeth eliminating
anterior crossbite and allowed spontaneous upper left second premolars eruption. At the eighteenth month of treatment,
overbite and overjet value was +2mm and midline maxillary and mandible arch paralled with in relation and centric
occlusion. In conclusion, early intervention for anterior crossbite and impacted second maxillary left second premolars
correction in this case was based on proper treatment timing and accurate diagnose by considering patient’s growth trend.
