Gingival Embrasure Fill In Fixed Implant-Supported Prosthetics: A Review

After provisional or definitive cementation of fixed implant-supported prostheses, spontaneous gingival proliferation may occur to fill the cervical embrasure areas of the prosthesis. Adequate oral hygiene, osseous spacing between the supporting implants and attached or immovable soft tissue may be the conditions that allow this phenomenon. This proliferation embrasure fill eliminates interproximal gingival voids, that is, black triangles, and makes the outcome more esthetically acceptable. Since interproximal prosthetic deign and implant positioning may be the primary factors for the fill, the gingival fill may be, in fact, an epulis.
