Classification Case report
Treatment of impacted canines is a challenge faced by orthodontists. Typical treatment includes extraction or forced eruption of canines. However, several complications may arise following surgical exposure and orthodontic forced eruption, and orthodontists need to beware of these situations when making a treatment plan. This case report describes the orthodontic treatment with maxillary canine impactions.
The case report is about a 15-year-old female patient who came for evaluation of the impacted tooth. Clinical examination revealed Angle’s class II molar relationship, unerupted left maxillary canine with 4 mm space between lateral incisor and first premolar, and a gingival bulge over anterior left palate. Radiographic examination indicated skeletal class I relationship, and left maxillary canine was impacted palatally and mesial-angularly. After space gaining, we used open method to erupt impacted canine, and stable occlusion was achieved 24 month later.
Discussion and summary
It is important for a tooth to erupt through the attached gingiva, not through mucosa, and this must be considered when exposure of an unerupted canine is planned. Surgical approach will be based on the location of the impacted tooth. There are three different ways of surgical approach, and orthodontists must choose appropriate methods to treat the impaction.
