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 having an anchoring system consisting of foldable fins actuated by an insertion screw; the dental implant is characterised by the following components: an implant body that includes an implant-abutment connection zone, an externally threaded zone, at least one pair of exit openings and an internally threaded zone; an anchoring having at least one pair of foldable fins and a top opening; an insertion screw having a head with an internal hexagonal socket, a stem and a screw thread; when the insertion screw is screwed into the top opening of the anchoring means, the insertion screw pushes the anchoring down into the implant body and causes the foldable fins to extend outwards through the exit openings.

An implant for insertion within a maxillofacial bone of a patient including a tapered body and one or more threads formed along the body. The one or more threads on one or more lead threads include multiple thread forms including both three-dimensional stabilization thread and standard thread (e.g. v-thread, buttress thread, etc.) forms. The one or more threads including the multiple thread forms provides for maximizing the restriction of lateral movement of the implant within a full or partial osteotomy.

A zygomatic dental implant includes a generally cylindrical body, an interior threaded bore, and an asymmetrical external feature. The generally cylindrical body has a coronal portion and an apical portion. The generally cylindrical body has a main-central axis. The interior threaded bore is formed in the coronal portion of the generally cylindrical body for receiving a screw configured to removably hold an abutment in engagement with the zygomatic dental implant. The interior threaded bore has a bore-central axis. The asymmetrical external feature is on at least a portion of a first side of the generally cylindrical body such that the asymmetrical external feature is configured to directly engage alveolar bone of the patient. The asymmetrical external feature includes a plurality of circumferentially extending grooves.

A dental implant includes an implant body extending along a longitudinal axis between a crown end and an apical end, the implant body having a core along which a helical thread extends with at least one thread, the core being tapered towards the apical end on at least one section of the length of the dental implant. At least two tapping grooves are arranged in the thread. The grooves interrupt the thread, so that the thread includes a series of consecutive thread arcs. Each thread arc has an apical surface oriented towards the apical end of the dental implant, and a crown surface oriented towards the crown end of the dental implant. A peripheral lateral surface connects the apical surface and the crown surface of the thread arc. In at least one section of the dental implant in which the core is tapered, at least one thread arc has a radial offset.

The one or more threads on one or more lead threads include multiple thread forms including both three-dimensional stabilization thread and standard thread (e.g. v-thread, buttress thread, etc.) forms. The one or more threads including the multiple thread forms provides for maximizing the restriction of lateral movement of the implant within a full or partial osteotomy.

A dental implant that facilitate insertion and can be used in all bone types. The implant includes a body having a coronal end, and an apical end opposite the coronal end. A tapered region may be adjacent the apical end. On the apical part one or more taps are provided so the tap is cutting when rotating clockwise and counter-clockwise. The implant can have at least one variable profile helical thread that extends along the tapered region. The implant can have also micro-threads below the main threads, a gradual compressing tapered core, a self drilling apical end and a narrow coronal region.

A fastener with improved threading for resisting multi-axial forces and off-axis loading scenarios is provided. The fastener may include a shaft and a plurality of helical threads disposed about the shaft. The plurality of helical threads may include a first helical thread and a second helical thread adjacent the first helical thread. The first helical thread may include a first concave undercut surface and a first convex undercut surface. The second helical thread may include a second concave undercut surface and a second convex undercut surface. When the fastener is viewed in section along a plane intersecting a longitudinal axis of the shaft, the first concave undercut surface and the second convex undercut surface may be oriented toward the proximal end of the shaft, and the first convex undercut surface and the second concave undercut surface may be oriented toward the distal end of the shaft.
