Abstract: Method for manufacturing a drilling template (9) and a support piece (3) for positioning this drilling template (9) in relation to the bone of a jaw, wherein a digital model of the dental prosthesis is designed starting from a digital mould such that it can fit to soft tissue of the jaw. According to the invention, a provisional dental prosthesis is manufactured based on the digital model, wherein this provisional dental prosthesis is positioned on the jaw and at least one image of the jaw with the dental prosthesis (1) is generated by means of tomography, wherein a position and orientation for said at least one implant are then selected on the basis of said image.

Abstract: A method is provided for manufacturing a template, whereby a digital or physical model of the shape of at least a part of the jaw is generated. A desired shape for the jaw bone for positioning a bone superstructure is compared to the model and a bone part of the jaw bone is identified, which bone part is to be removed in order to approach the desired shape. A guide surface is provided on the template to guide a milling element in order to remove the identified bone part. A bone superstructure is also described.

Abstract: The invention concerns a method for manufacturing a template (6), whereby a digital or physical model of the shape of at least a part of the jaw (1) is generated. A desired shape for the jaw bone (2) for positioning a bone superstructure (25) is compared to said model and a bone part (5) of the jaw bone (2) is identified, which bone part (5) is to be removed in order to approach said desired shape. A guide surface (8) is provided on the template (6) to guide a milling element (10) in order to remove the identified bone part (5). The invention also concerns a bone superstructure (25).

Abstract: A method and marker element to determine the position of a prosthetic element (2) which is fixed to the jaw (13) of a person, such as a dental implant. An image is formed of the jaw of a reproduction model of this jaw which is provided with the prosthetic element (2), by means of X-rays or magnetic resonance. At least one marker element (3) is then provided on the prosthetic element (2) which produces a strong contrast in imaging techniques. The position of the marker is then formed by X-rays or by magnetic resonance, and the position of the prosthetic element (2) is then derived from the observed position of the marker element (3).

Abstract: The invention concerns a method for manufacturing a template with at least one opening to drill through so as to create an appropriate bore hole in the bone of an at least partially toothless lower or upper jaw so as to fix an implant in said bone.

Abstract: The invention relates to a template for placing at least one dental implant (7) in a jaw (1) having at least one bore (3) for guiding this implant (7) when it is fixed in the jaw (1), whereby a recess (4) is provided that opens at least partly in said bore (3) in order to enable verifying the position of a implant guide with the implant.

Abstract: The invention concerns a method for manufacturing a template with at least one opening to drill through so as to create an appropriate bore hole in the bone of a partially toothless lower or upper jaw so as to fix an implant in said bone. Hereto a mould plate with a means of reference is made which can be put in a fitting manner over teeth which are present in the jaw and a position for the corresponding bore hole is selected and determined in relation to said means of reference. An aligning plate is made, provided with fixing means which make it possible to mount the aligning plate on the mould plate. Said opening in the aligning plate for guiding a drill is provided in such a position that, when the aligning plate is mounted on said mould plate and the latter has been provided in a fitting manner on said teeth, the position of this opening makes it possible, when drilling through said opening, to create said bore hole in correspondence with the selected position.

Abstract: The invention concerns a method for manufacturing a bone superstructure (4) and a dental implant system with an implant (5) and a bone superstructure (4) to at least partly fill bone defects (2) in a jaw (1), whereby the bone superstructure (4) has a bone side (11) which is intended to extend opposite the bone which surrounds said bone defect (2) and a free side (10) onto which the gingiva (9) should connect, whereby this bone superstructure (4) has at least one recess (6) with a circular cross section extending between said bone side (11) and said free side (10), which recess (6) has a conical wall (8) and whereby the implant (5) is conical over at least a part (14) of its height, such that it can be mounted in the recess (6) in a substantially fitting manner.

Abstract: The invention relates to a method for mounting a superstructure (19) of a dental prothesis on implants (1) which are provided in the bone (24) of a patient's lower or upper jaw (25), whereby these implants (1) form loadable (1a, 1c) and non-loadable (1b) implants. The superstructure (19) is fixed on the head (4) of the loadable implants (1a, 1b), whereby a supporting element (2) is mounted between said head (4) and the superstructure (19), whereas a free space (26) is preserved between the head (4) of the non-loadable implants (1b) and the superstructure (19).
