Dental implant having a socket arrangement having the shape of a regular octagon which is partly interrupted by outwardly extending notches being parallel or parallel and partly inclined with respect to the longitudinal center axis of the implant, the inclination being such as to taper inwardly from their coronal end, wherein interrupting and outwardly extending ridges extending from the notches in an apical direction of the dental implant, first contact surfaces being adapted to engage and rotationally secure an abutment, and wherein second contact surfaces extend from the notches within the ridges in the direction of the longitudinal center axis, the second contact surfaces being adapted to engage with an insertion tool; and wherein the notches are positioned at sides or at corners of the regular octagon.

A root assembly includes an implant body and a positioning device connected to the implant body. The implant body has a positioning hole formed through one end thereof and an engaging portion opposite to the positioning hole. The positioning hole has an end edge. The positioning device has a positioning seat where an artificial tooth is attached and a positioning unit extending through and out of the positioning seat. A first recognition portion is formed on the positioning seat. The location of the first recognition portion of the positioning seat corresponding to the end edge of the positioning hole can recognize that the positioning device is exactly positioned on the implant body, thereby preventing the positioning device from loosening.

Disclosed herein is a cleaning system (30) for a dental implant part (2) that has been introduced into the jaw bone of a patient. For this purpose, in an advantageous embodiment of the invention, a securing element, which is adapted on the end side to connect to a corresponding connection element in the dental implant part, particularly preferably which can be screwed into a thread of the dental implant part by the end side, and to which a distribution element for a cleaning fluid as well as an electrical contact element can be attached, which distribution element can be connected to an external media reservoir via a media channel, and via which electrical contact element, a power source that is connectable to an external power source can be electrically connected to the dental implant part.

The invention provides a method for dental restoration including direct modification or customization of a final abutment inside the patient's mouth. The final abutment is made from a non-titanium material. The final abutment, after being completely modified or customized, may then be used to support a crown. The invention exhibits numerous merits such as simplified procedure, cost-effectiveness, reduction of laboratory adjustment, reduction of chair time, and reduction of dentist office visits.

A threaded dental implant to be screwed into a jawbone for supporting at least one abutment and/or a dental superstructure, and having a socket arrangement with a first section and a second section with respective geometrical profiles around a longitudinal center axis of the implant. The first section cooperates with the abutment for securing the abutment in a determined position in the implant. The second section cooperates with an insertion tool for screwing the implant into the jawbone. The first section includes an annular coronal contact surface on top of an opening centric at a coronal end of the implant, followed in an apical direction by a first tapered section having a diameter decreasing in the apical direction, by a first cylindrical section, by first anti-rotational elements and by a threaded section.

Dental implant assembly comprising an implant with a body having an outer implant surface configured for osseointegration and a connection well, and an abutment comprising a prosthesis mounting portion for assembly of a dental prosthesis thereon and a connector mounting cavity. The assembly further comprises a connector comprising an implant mounting portion for assembly in the connection well of the implant, and an abutment mounting portion for assembly in the connector mounting cavity of the abutment, the abutment mounting portion of the connector comprising an index portion and the abutment connector mounting cavity further comprising an index cavity portion for receiving the index portion therein, the index portions configured to register the rotational orientation of the abutment about a longitudinal axis (A) with respect to the connector.

A dental implant for securing an abutment to a jawbone, the implant including a tapered body having a longitudinal axis, the body including a coronal end and an apical end, the coronal end including an inclined coronal surface. A first bore receives a base portion of the abutment, the first bore extending downwardly from the coronal surface and parallel to the longitudinal axis of the body. A second bore with a footprint larger than the first bore includes a flange adapted to be abutted by a top portion of the abutment, the diameter of the second bore being off-axis and larger than that of the first bore.

A fixed, detachable dental attachment device has a cap for securing a dental appliance, a ring, and an abutment to attachment to a tooth root or implant. Also described herein are methods of securing a dental appliance in a subject's mouth by means of the dental attachment device. Further described herein is a dental attachment device for immediate load on a provisional denture and then incorporated into the final restoration.

The invention relates to a scan abutment (2), in particular an integrally manufactured scan abutment, for determination of the position of the front face (1.1) of a dental endosseous implant (1), wherein the abutment (2) has a longish, hollow shaft (4), and the shaft has an upper region (4.1), a central region (4.2) and a lower region (4.3). Moreover, the shaft (4) of the scan abutment with its central region (4.2) is attachable onto the front face (1.1) of the implant (1), and its lower region (4.3) is insertable into the connection geometry of the implant. The longish, hollow shaft (4) has a side wall (10). The shaft of the scan abutment has at least two to terminally extending slits (5) in its central region (4.2) and lower region (4.3) in the side wall (10). Two, three or four slits are preferred. Preferably, the slits (5) end in one recess (6) each, such as a circular recess, in the side wall (10) at their upper end and extend terminally in the side wall (10) to the bottom side of the shaft (4). Another subject matter of the invention is a kit comprising a scan abutment as well as the screw adjusted to the scan abutment or the bolt adjusted to the scan abutment.

A series of at least three abutments for dental use and a method for selection and aligning an abutment therefrom in a patient mouth. The series comprises at least three abutments. Each abutment composes a mate of a polygonal rotation preventive adapter having an axis of rotation perpendicularly to a lateral cross section, and a support member extending from a proximal end of the mate and having rotational symmetry to the axis of rotation. A projection of the support member on a plane of the lateral cross section in at least one abutment, is asymmetric with respect to angle bisectors and medians of the polygonal shape. An angle between a straight line extending from the axis of rotation to a reference point on a projection circumference of the support member forms a unique offset angle with a side of the polygonal shape per each dental abutment in the series.
