A method for manufacturing a dental structure, a dental structure and a dental assembly, formed by a structure screwed on a dental implant relates to a manufacturing method of a dental structure intended to be located and screwed on a previously osseointegrated dental implant, as well as to the structure obtained according to said method and to the dental assembly formed by said structure and implant.

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.

A biomimetic composite material includes a bioactive cement material, an autologous dentin matrix, and an inorganic nano-reinforcement material. A dental implant includes a body including a biomimetic composite material, wherein the biomimetic composite material includes a bioactive cement material, an autologous dentin matrix, and an inorganic nano-reinforcement material.

A dental implant for supporting periodontal tissue and the supporting bone is provided. The dental implant includes an implant member with inner canal for insertion into a periodontal bone socket, and an anchoring assembly. The anchoring assembly includes a first fastening element and radially equidistant cylindrical members. The first fastening element engages the implant member within the hollow axial cavity. The root section includes through-holes for radially and forcibly sliding the cylindrical members through them. When the first fastening element apically advances within the hollow axial cavity, the cylindrical members generate an anchoring force to anchor the dental implant.

The present invention provides a method for preparing an implant including preparing a mixed etching composition including hydrogen peroxide and a water-soluble carbonate compound and oxidatively etching an implant made of titanium or a titanium alloy by immersing the same in the etching composition; a titanium or titanium alloy implant prepared by oxidative etching with a mixed etching composition including hydrogen peroxide and a water-soluble carbonate compound; and a composition for treating surface of an implant containing hydrogen peroxide and a water-soluble carbonate compound. Further, the present invention relates to a titanium or titanium alloy implant which is prepared by oxidative etching with a mixed etching composition including hydrogen peroxide and a basic solution and on which surface bumps having continuous or discontinuous line-shaped open channel structures in nanoscale are irregularly formed, and a preparation method thereof. The surface of the titanium alloys treated with the mixed etching composition including hydrogen peroxide and a carbonate compound or the etching composition containing hydrogen peroxide and a basic solution of the present invention includes micrometer-sized bumps and channel-shaped nanometer-sized bumps, and thus has an increased surface area, and can not only improve wettability, but also effectively promote cell proliferation and osteocyte differentiation. In addition, the composition includes no chemical compounds such as a strong acid, etc. and is thus environmentally friendly, and such compounds can be prevented from remaining on the surface, which can improve biocompatibility, and therefore, the composition can be useful for implant surface treatment.

An occlusal screw for a two-part dental implant system with an anchoring part and an abutment includes a screw head and a screw shank. The screw head apically forms a screw stop. The occlusal screw consists of a ceramic material and has an engagement portion with an outer structure that is not rotationally symmetrical about the screw axis, is cylindrical or conical at least in regions and is suitable for interacting with a corresponding inner structure in a distal recess of a screwing tool, in order to couple the occlusal screw onto the screwing tool in a rotationally fixed manner. A design concerning which the engagement portion occlusally includes a cylindrical region and apically thereof a clamping region, which continuously widens in the apical direction, is particularly advantageous. The clamping region can be for example conical.

A screw suitable for use specifically in the field of oral dental surgery consists of a bioresorbable material and comprises a drive that can be broken off by means of a predetermined breaking point and/or has a thickened shaft below the contact surface of a cap of the head of the screw.

Dental screw which can be inserted into a cavity of a patient's maxillary and/or mandibular bone, including a terminal portion that can be inserted into the cavity so as to fit within it and so as to engage a side wall thereof. The dental screw further includes a cervical portion, configured to engage an artificial tooth structure, and a central portion extending longitudinally between the terminal portion and the cervical portion. The central portion is shaped as a porous structure, particularly as a trabecular structure, to promote an intraosseous regrowth process. The dental screw is further characterised in that the terminal portion, the central portion and the cervical portion are made from a single piece.
