Abstract: A device for “treating” gingiva/mucosa at teeth/implants comprises at least one segment comprising a contour surface formed according to an individual geometry of a patient's dentition for closely contacting a region of an outer surface of a tooth and an adjacent region of a gingiva, whereas the regions in particular include a sulcus region, a storage and/or supply for a composition including a cleaning agent, a remineralizing composition, and/or a pharmaceutical composition to be applied to the regions of the tooth and the gingiva and a transmission element for transmitting vibrations to the at least one segment.

Abstract: A device for detachment and explantation of bone implants, in particular tooth implants, from their connection to the bone tissue comprises a unit having an elongated handle (10), a cooling module (7), a vibration module (8) for generating mechanical vibrations, and a grip head (6) which is secured to the handle (10) and which has a seat (14) for the bone implant to be explanted, in particular an implant head of the bone implant, or for an adapter piece for gripping the bone implant. The grip head (6) is coupled to the cooling module (7) and to the vibration module (8) in such a way that it is coolable to a desired temperature by means of the cooling module (7), and the vibrations of the vibration module (8) are transferable into the grip head and further to the bone implant or the adapter piece. The seat in the grip head (6) has at least one clamping element (12-15) which is able to exert radial clamping forces, with respect to a rotational axis, on the bone implant or adapter piece held in the seat (14).
