Classification case report

Maxillary canine impaction is one of the frequently occurred malocclusion.
The aim of this case report was to discuss clinical considerations of maxillary impacted canine management.

This is a 15 years old male, with bilateral maxillary canine impaction. He came for orthodontic evaluation with chief compliant of proclined incisor and spacing between upper incisors. Clinical examination diagnosed as Angle’s class I molar relationship, bilateral maxillary canine impaction with labial malposition.

Treatment overview:
The treatment plan was to extract right maxillary canine, left maxillary first premolar and bilateral mandibular first premolars. The left maxillary canine was surgical exposed by closed eruption techniques. The straight wire orthodontic technique was used in this case. After finished orthodontic treatment, the flare incisor was retracted and extraction space was closed with good buccal interdigitation and symmetrical arch form.

Canine plays an important role in occlusal function and esthetics. The extraction of canine may be indicated by canine position relative to the arch form and the esthetics of patient profile.   How to adjust the premolar replacing the extracted canine and need canine guidance or not should be considered.  The periodontal consideration of exposed impacted canine also needed to focus on the keratinization gingival level. 
Many factors might affect the impacted canine treatment plan.  The occlusion, function, esthetic and health of the canine should be evaluated in impacted canine treatment.
