Recovering teeth from a large dentigerous cyst: A case report.

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.
