The invention relates to an abutment for use in a dental implant system, wherein the abutment is provided with a guiding and lock for associating the abutment to a dental implant, the guiding and lock including: a first conically tapered section; a second substantially non-tapered section arranged apically adjacent to the first section, the second section being provided with an anti-rotational means; and a third substantially circular cylindrical section arranged apically adjacent to the second section, such that to provide axial guiding to the abutment upon the insertion thereof into a dental implant. Further, the invention relates to a dental implant formed in a similar manner.

A dental prosthesis system, for the use with at least two dental implants, wherein the dental prosthesis is divided in a first prosthetic part and a second prosthetic part, jointed by a prosthetic screw, and wherein the first prosthetic part is connected to the dental implants through at least two connectors, and such dental prosthesis has an engaging and guidance system, including two female elements, disposed on the top of the first prosthetic part, and two corresponding male elements, disposed on the bottom of the second prosthetic part, whereby the connection between the two female elements and the two male elements is releasable. The problems solved in the prior art are related to a bending moment derived from masticatory forces. The solution comprises installing a mechanical weakness in the prosthesis to protect the bone tissue.

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.

A dental prosthesis implant which has an endosseous implant portion extending along an implant axis and a transgingival portion extending from the implant portion and forming an implant-prosthetic connection platform is provided. The implant-prosthesis connection platform extends perpendicularly with respect to a prosthetic axis, the prosthetic axis being inclined with respect to the implant axis. The transgingival portion forms a side wall with a diameter equal to or smaller than the diameter of the endosseous implant portion and progressively decreasing at least in a distal transgingival portion ending with the implant-prosthesis connection platform.

A method for manufacturing at least one bone anchor and a corresponding drilling template, wherein the bone anchor has an anchor plate which is to be fixed to the surface of a bone by means of one or several screws having a screw head. The anchor plate thus has a bone side which is to connect to the surface of the bone and a free side which is opposite to said bone side. Further, a method for manufacturing a drilling template is described, making it possible to make bore holes in the bone at predetermined positions and to screw the bone anchor to the bone according to predetermined orientations.

The present invention relates to an advancement in dental implants procedures where a novel from of double threaded dental implant structure is disclosed. The proposed assembly's large thread pitch allows better stability and reduces the stress on associated tissues and organs.

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.

A dental prosthesis (100) for anchoring in the jawbone (1), comprising a dental implant (110) with an implant body (111) and an abutment (112), a tooth part (120) with an internal guide (122) in the tooth part (120), in particular penetrating the tooth part (120), and a closure body (130) for sealing the dental prosthesis (100) within the internal guide (122) in the tooth part (120), in particular penetrating the tooth part (120). A connecting sleeve (140) is arranged between the closure body (130) and the internal guide (122) of the tooth part (120), by means of which connecting sleeve the tooth part (120) and the dental implant (110) can be connected to one another indirectly, detachably and/or by means of which connecting sleeve the closure body (130) can be releasably locked within the internal guide (122) in the tooth part (120), in particular penetrating the tooth part (120).
