Abstract:
1. A dental restoring system comprising: a dental implant osteointegrated in a jaw bone; an abutment having a prominent contour and a surface extending from the prominent contour in an apical direction, the abutment being engageably connectable to the dental implant; an impression gingival cuff for taking an impression during a restoration procedure, the impression gingival cuff comprising two open ends including an apical end with an apical opening oriented towards the apical direction and a proximal end with a proximal opening oriented towards an occlusal direction, an inner surface oriented towards the abutment and an outer surface oriented towards surrounding gingival tissue, the inner surface of the cuff shaped and sized to receive the surface of the abutment through the proximal opening of the cuff and to retain the abutment in the occlusal direction when the abutment is engaged to the implant; and an impression tray installed on a proximal end of the abutment for receiving impression material that transmits hydraulic force to the cuff to achieve an apical translation of the cuff and to allow the impression material to advance beyond the prominent contour in the apical direction while the outer surface of the impression gingival cuff pushes the surrounding gingival tissue away from the abutment.
