Management of excessive gingival display following adult orthodontic treatment: a case report.

A common cause for the condition described as excessive gingival display is the phenomenon known as altered passive eruption, a coronally situated gingival complex that failed to recede normally during eruption of an otherwise healthy and normal dentition. Orthodontic movement in such conditions may set the stage for additional coronal growth of hyperplastic gingival complex. The objective of this article is to describe, through a detailed case presentation, the surgical methods used to achieve healthy and aesthetic gingival contours in such conditions.
