A dental implant includes a body and a thread. The body has a central axis, a coronal end, and an apical end. The thread is coupled to the body. The thread has a coronal facing surface, an apical facing surface, and a crest surface positioned between the coronal facing surface and the apical facing surface. The coronal facing surface of the thread has a plurality of steps formed therein.

An approach is disclosed that involves creating an implant-supported prosthesis that is dynamically guided into position using an image-guided navigation system into position in a patient's mouth without the use of a surgical guide.

An external drive apparatus for bendable collar implants includes a male fastener and a female driver. The male fastener is constructed as a rigid and integral unity including an implant screw, a collar, and a male screw-top drive. The female driver supports a female screw-top drive. The female driver is configured for application of an implantation torque to the implant screw via the male screw-top drive which is disposed distally away from the collar.

Component (1) for endosseous screw, provided with a main body (10) which supports electronics (2) comprising at least one signal emission circuit and at least one sensor for acquiring one or more biophysical parameters of a patient, said component (1) being associable with an endosseous screw.

A dental implant evaluation unit is disclosed and described. The dental implant evaluation includes a body portion having threads that mimic the general thread pattern of an actual dental implant, without attempting to copy any of the osseointegrative features of the actual implant. A threaded collar is associated with the body portion, and, in certain embodiments, a safety flange is screwed to the threaded collar. The safety flange prevents the dental implant evaluation unit from infiltrating the sinus of a patient when testing the fit of a maxillary implant. The dental implant evaluation unit can be used by a dentist to evaluate the proper size and fit for an actual dental implant by installing the dental implant evaluation unit, and imaging the same, prior to installing the actual dental implant.

A method of installing a dental prosthesis that includes having a practitioner install at least one narrow implant and at least one standard implant into a subject's bone, where the narrow implant has a narrow implant abutment that is exposed after installation, and the standard implant has a standard implant abutment exposed after installation. The practitioner places a narrow implant housing over each narrow implant abutment, and places a standard implant housing over each standard implant abutment. The practitioner flows a resin within a channel located within a dental prosthesis and places the dental prosthesis over each narrow implant housing and each standard implant housing such that the resin surrounds each narrow implant housing and each standard implant housing. Once the resin cures, each narrow implant housing and each standard implant housing is fixed within the resin and the resin is fixed within the 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.

Described are ready-to-use injectable compositions comprising polymeric microspheres or microparticles of non-animal origin, a hydrogel comprising water and a cellulose-derivative gelling agent, and polysorbate 80. Further described are methods of using the ready-to-use injectable compositions for reparative or plastic surgery, esthetic dermatology, facial contouring, body contouring, and gingival augmentation.
