An impression gingival cuff for taking an impression during a restoration procedure of a dental implant osteointegrated in a jaw bone. The dental implant is engageably connectable with an abutment having a prominent countour. The impression gingival cuff has a tubular-conical shape, a circumferential thin wall, two open ends including an apical end oriented towards a tooth root and a proximal end oriented towards an occlusal direction, an inner surface oriented towards the abutment and an outer surface oriented towards surrounding gingival tissue. During installation of the cuff between the dental implant and the abutment, the apical end retains the prominent contour of the abutment so that the outer surface of the cuff pushes the surrounding gingival tissue away from the abutment. This allows taking an accurate impression of both the dental implant and abutment in order to fabricate a high precision restoration. |
