Garber and Salama presented three classifications for excessive gingival display and their proposed treatments. Degree I had 2 to 4 mm of gingival display, and treatment would be orthodontic intrusion alone, orthodontics and crown lengthening or crown lengthening followed by restorations. Degree II had 4 to 8 mm of gingival display, and treatment would be crown lengthening and restorations or orthognathic surgery depending on the crown/root ratio. Degree III had >8 mm of gingival display, and treatment would be orthognathic
surgery with or without crown lengthening and restorative treatment.


Coslet et al. For Type I cases with adequate KG (>2 mm), if CEJ–bone is >2 mm (subgroup A), a gingivectomy/gingivoplasty procedure can be done.
If CEJ–bone is <2 mm or CEJ is at the same level as the alveolar bone crest (subgroup B), then a flap with osseous surgery is done. In Type II cases with inadequate KG (<2
mm), an apically positioned flap (APF) is indicated for subgroup A. For subgroup B, an APF with osseous surgery is done
