RESUMO

With the increasing interest on the achievement of esthetics in implant-supported rehabilitations, the peri-implant soft tissues have been addressed in several investigations in Implantology. The congenital alveolar cleft is distinguished within this context because of the inherent esthetic impairment. This retrospective study assessed the gingival esthetics of 65 single implant-supported prostheses at grafted cleft areas by a new index based on the following parameters: position of the gingival margin, interproximal papillae and gingival color. Esthetics was scored as satisfactory or poor. The scores achieved by this index were associated to the status before and after placement of the implants (gingival recession of the adjacent teeth, buccal frenula, width of keratinized mucosa), to the reconstructive surgical procedures (bone grafts, gingival grafts, reopening and flap techniques), and to the number of surgeries and gingival conditioning sessions performed to achieve esthetics. The peri-implant gingiva of 42 prostheses (64.62%) was considered satisfactory. Gingival recession on the adjacent teeth, presence of buccal frenula and lack of keratinized mucosa were the main factors influencing the poor esthetics of the other prostheses. The only type of surgery that interfered with the esthetic outcome was the epithelialized free gingival graft. The number of gingival conditioning sessions did not interfere with the outcomes. It was concluded that the status before placement of the implants are more important for achievement of esthetics than the reconstructive surgical posterior procedures or gingival conditioning. Moreover, the index proposed was adequate for this type of evaluation.
