Abstract: 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.
