Radiographic dental jigs and associated methods
11744530 · 2023-09-05 ·

Example radiographic dental jigs include a generally vertical post traversed by a generally horizontal beam to create a cross that can be used for marking a dental patient's midline (vertical line centered between the eyes), incisal edge plane, and forward lip position. The jig is radiographically scanned along with multiple fiducial markers on the patient's jaw to generate a first scan result. In some examples, physical models of the patient's jaws are also scanned to generate upper and lower jaw images. The upper and lower jaw images are shifted to coincide with the first scan result. Portions of the first scan result, including an image of the dental jig, are superimposed onto the properly shifted upper and lower jaw images to create a composite image. The composite image shows the dental jig in proper relation to the patient's upper and lower jaws, thereby rendering a conventional stick bite virtually obsolete.

A fixture for insertion into a bore hole arranged in bone tissue is provided. The fixture has a threaded leading portion provided with at least one cutting edge for creating a female thread in the bone tissue, and a threaded trailing portion following the leading portion in the created female thread. Compared to the geometry of a thread peak of said cutting edge of the leading portion, a thread peak of the trailing portion is displaced or overdimensioned in at least one of the coronal and apical directions of the fixture so that a strain is provided to the bone when said displaced or overdimensioned thread peak engages with the created female thread. A fixture set for creating a strain is also provided, the set includes a fixture and a separate thread maker.

Device to be implanted in human or animal tissue and method for implanting and assembling the device

An implant or endoprosthesis suitable to be implanted in human or animal tissue includes two (or more than two) parts to be joined in situ. Each one of the parts includes a joining location, the two joining locations facing each other when the device parts are positioned for being joined together, wherein one of the joining locations includes a material which is liquefiable by mechanical vibration and the other one of the joining locations includes a material which is not liquefiable by mechanical vibration and a structure (e.g. undercut cavities or protrusions) suitable for forming a positive fit connection with the liquefiable material. The joining process is effected by pressing the two device parts against each other and by applying ultrasonic vibration to one of the device parts when the two parts are positioned relative to each other such that the two joining locations are in contact with each other.

Ceramic Bodies Having Antimicrobial Properties and Methods of Making the Same
20220233279 · 2022-07-28 · ·

A method for making a ceramic body comprised of a ceramic material having an inhibitory effect on bacterial growth is provided. A dental prosthesis may be made of a ceramic material that comprises a molybdenum-containing component on a portion of the prosthesis that contacts the gingival surface of a patient. In one method, a porous zirconia ceramic structure is shaped in the form of a dental prosthesis, and then infiltrated with a molybdenum-containing composition, before sintering to densify the ceramic structure.

Threadless Dental Implant, System Including a Threadless Dental Implant, and Method of Attachment of a Threadless Dental Implant

Method For Producing A Dental Prosthesis, Blank And Dental Prosthesis

A method is provided for producing a dental prosthesis from a blank using a CAD/CAM device, wherein the blank consists partially of base material and partially of tooth material, and a boundary surface between these materials is formed as a wave, the wave crests and wave valleys of which alternate with each other along the outer periphery of the blank. The apex of each wave crest extends substantially radially with respect to the blank. The CAD/CAM device fixes the position of a retention part, which serves to fasten the prosthesis to the alveolar crest of a patient, in particular of an external telescope, of a cover of a bar, or of an abutment in the prosthesis in such a way that it passes through the boundary surface. The retention part is fastened by means of gluing or incorporation by polymerisation.

Method for producing an implant blank

A method for producing an implant blank (100), in particular a dental implant blank from a starting body, said implant blank (100) comprising at least one first area, which is a surface area (102), and a second area, which is a core area (101), wherein the surface area (102) has at least one bioactive surface material (502) and extends from at least one first surface (103) in the direction of the core area (101), and the core area (101) has at least one carrier material that can be subjected to mechanical load. The starting body has a porosity for controlling a targeted distribution of the bioactive surface material (502) within the starting body and is loaded with a solution (500) of the bioactive surface material (502) in a first step, which is a loading step. In a second step, which is a distribution control step, the distribution of the bioactive surface material (502) within the starting body is controlled such that the solution (500) has a higher concentration within the surface area (102) than within the core area (101), the control being effected by regulating one or more environmental parameters in a closed environment (200), in particular by regulating the humidity and/or the pressure and/or the temperature.
