RESUMO
A male patient aged 11 years presented a large dentigerous cyst in the lower left quadrant associated with retained deciduous lower lateral incisor and canine and impacted, unerupted corresponding permanent ones. The treatment consisted in marsupialisation and placement of a modified lingual arch that held a tube for decompression used for irrigation of the cystic cavity in a comfortable way for the patient and for the clinician.The same lingual arch was later used as an anchorage method for traction of the retained teeth. The final records showed complete resolution of the cyst and retained teeth were successfully Aligned into the oral cavity.

This case report discussed a combined surgical-orthodontic rescue of two impacted teeth in a large dentigerous cyst by the means of fixed orthodontic appliances. After careful evaluation of the 3D radiographic exams, extraction of the deciduous elements was carried out, followed by marsupialization and orthodontic traction of the impacted teeth. Surgical procedures, pre- and posttreatment records and orthodontic biomechanical evaluations are discussed.

A dentigerous cyst is an odontogenic lesion caused by the expansion of the follicle surrounding the crown of impacted, embedded or unerupted teeth. These cysts may cause destruction of the bone, displacement of adjacent teeth, resorption of their roots and prevent the eruption of cyst-associated permanent teeth. This paper discusses successful use of marsupialization combined with orthodontic treatment to treat cyst-associated impacted permanent teeth and to correct a class II open bite malocclusion.

The goal of this treatment was the surgical- orthodontic rescue of the impacted teeth in a large dentigerous cyst, in a growing patient, by fixed orthodontic appliances. Initial and final records and progress in treatment are shown. The Authors demonstrate that a good result my be reached in this cases even if initial position of the cyst-associated teeth is critical and translocation of an adjacent tooth in the arch occurs.
