Abstract: A screwdriver for medical, in particular dental applications, is provided, the screwdriver (2, 2?, 2?) being configured to cooperate with a screw (1, 1?), the screw (1, 1?) having an apical end (11), a coronal end (10), a screw axis (S) and a first recess (14) at the coronal end for engagement with the screwdriver, the first recess (14) having a substantially polygonal inner contour in a radial plane that is perpendicular to the screw axis (S), the screwdriver (2, 2?, 2?) comprising a shaft (2) defining a longitudinal axis (D) of the screw driver, and an engagement portion (21, 21?, 21?) for engagement with the first recess (14) of the screw (1, 1?), the engagement portion (21, 21?, 21?) having a substantially polygonal outer contour with corners (23, 23?, 23?) and outer surfaces (22, 22?, 22?) between the corners (23, 23?, 23?) wherein in a radial plane that is perpendicular to the longitudinal axis (D), the outer surfaces (22, 22?, 22?) between two neighbouring corners (23, 23?, 23?) are curved radially out

Abstract: A surface treatment process for an implantable medical device including a surface dielectric insulating layer, the process comprising the application of ions onto said dielectric insulating layer, the ions being capable of forming an electrostatic charge and locally creating an electric field associated with at least part of the surface of said implantable medical device upon application of a liquid to said surface.

Abstract: A reinforced surgical membrane for supporting bone growth by shielding a bone cavity from soft tissue in-growth comprises are a reinforcing layer (2) between a first membrane layer and a second membrane layer (4). The reinforcing layer (2) has defined therein an array of holes (3) which may connect the first and second membrane layers.

Abstract: Various embodiments for a spacer element that may be used in a dental implant assembly are described. In one example, the spacer element has a single aperture therethrough. Further, the single aperture includes an implant screw access bore and an offset abutment screw bore, longitudinal axes of which intersect within the single aperture.

Abstract: A surface treatment process for improving the hydrophilicity of at least part of an implantable medical device. The process comprises applying to the surface of the implantable medical device a solution of a non-ionic substance having at least one polar covalently-bonded group and drying the implantable medical device to form a hydrophilic deposition of the substance on the surface of the implantable medical device.

Abstract: An implant for anchoring a tightly fitting prosthesis includes an externally threaded implant body configured to be screwed into bone using an insertion tool, the body having a first end and a second apex end, said first end being provided with an internal open ended axial bore, the implant being tapered such that the apex end is smaller in diameter than the first end where the taper is not greater than 2°. The implant is also provided with an incremental cutting face.

Abstract: Various embodiments related to a locking ring for a dental implant assembly are disclosed. In one example, the locking ring is adapted at one end to engage with an implant screw, such as the head of the implant screw, and at an opposite end is adapted to engage with a dental prosthesis.

Abstract: The present invention is directed to a threaded implant intended to be screwed into bone, preferably into jawbone, and for tightly fitting a prosthesis, including a spacer portion, in the screwed-in position. The implant body has an internal connection arrangement for rotationally locking said spacer, said arrangement also co-operating during positioning and insertion of the implant body with a tool and said arrangement having a low vertical height.

Abstract: A dental impression coping which includes a set of components including an attachment screw access means through the impression material and not more than one attachment screw, that may be used for both pick-up type (open tray) or transfer tray (closed tray) impression moulding techniques. The impression components include an impression coping having non-rotational features and height specific retention means having an outer surface with its bottom end configured to reside preferably below the gingiva surrounding the implant. Means exist on the impression coping, to attach the impression coping to the implant for use in a transfer type impression application. By providing a means to access the attachment screw through the impression material a second impression application, the pick-up type impression application, can be performed, using the same screw that can be used also for the first impression application the transfer type impression application.
