Abstract
|
|
|
|
Excessive gingival display that can be seen when a person smiles can cause non-esthetic problem. This gummy smile is mainly caused by an altered passive eruption, bony maxillary excess, and excessive maxillary lip mobility. Thus far, an altered passive eruption has been successfully treated using esthetic crown lengthening. Recently, an alternative to orthognathic surgery has been proposed for the treatment of a gummy smile. Studies using a lip repositioning procedure have actively been performed. In this report, we present three cases of treatment for excessive gingival display using the modified lip repositioning technique associated with esthetic crown lengthening.
