Abstract: A bridge support (1, 60, 90, 140) for arrangement to an implant (2) has a surface abutting (30) the implant (2), and a first compressible sealing (31) integrally made with said surface (30). The bridge support (1, 60, 90, 140) has a through channel (33) ending at said surface and is shaped so that a shoulder (34) is formed inside said channel (33), and has a second compressible sealing (35) integrally made with said shoulder (33). According to a second embodiment the bridge support (1, 60, 90, 140) has external protrusion at an outside (160) integrally made with the bridge support (1, 60, 90, 140). A screw (3, 250) for fastening the bridge support (1, 60, 90, 140) to an implant has a head (230, 252) with an abutment surface (231) and a stem (232, 252), and has a compressible sealing (237) integrally made with said abutment surface (230). The stem (232, 252) has an external longitudinal recess (234) or a longitudinal through hole (251).

Abstract: A device (10) for debridement of dental implants, which are arranged into bone tissue and are surrounded by gingiva of a jaw of a human being, has a debriding element (11) and an axle (12) with a fastener (13) for attachment to a rotational apparatus The debriding element (11) has at least one cleaning leg (20) with at least one cutting edge for engagement with the implant, the gingiva and/or the bone tissue According to a second embodiment the debriding element has several portions each having said cleaning leg (20) and the portions are connected to each other Said cleaning leg (20) has a free end (21) shaped as a hook (30) with a point (31), which is provided with said cutting edge The device (10) may have several cleaning legs (20), each provided with several cutting edges A method for cleaning and abrasion of dental implants and implant sites are provided, which uses the device (10) for abrasion and cleaning.
