The invention relates to a screw, a tool and a system for dental implantology, forming a fixing system and the components thereof to be used in a dynamic pillar assembly. Said dynamic pillar assembly is used in the production of prostheses on dental implants in human implantology in order to fix screws at an angle.

The invention discloses a modular surgical bone screw assembly having a threaded base portion and a screw head adapted to attach a variety of structures to bone. The features of the screw include a modular design for the assembly that separates the function of anchorage to the recipient bone to one of the modules of the device (threaded portion) from the other function of attaching another element (such as bone block, membrane, orthodontic wires, elastics etc) to a second module (the screw head). The design also allows the head to be exchanged after the implant has been placed.

A dental prosthesis securing system secures a dental prosthesis to a dental implant. An abutment for cement has a base surface for placement against the dental implant. The base surface does not define an engagement shape that requires alignment with a complementary shape defined by the implant. A securing mechanism secures the abutment for cement to the dental implant.

The invention relates to methods of stabilizing bone implants, including inserting a self-tapping implant having at least two helical grooves running in opposite directions around the implant.

A medical implant and a method of implanting a medical implant are disclosed. The medical implant (20) is elongate and for fixation in a patient, and comprises an apical bone anchoring portion (200) for bone apposition, and an unthreaded coronal portion (210), wherein said coronal portion (210) has a length (L.sub.2) exceeding or equaling a length (L.sub.1) of said apical portion (200), and wherein said apical portion (200) has a maximum outer diameter (D.sub.1) that is equal to or larger than a maximum outer diameter (D.sub.2) of said coronal portion. In a method of implanting a medical implant, an apical part is affixed in the zygomatic bone, and a coronal part is positioned outside the maxilla in the mucous membrane.

A set of components for dental prosthetic restoration includes a ceramic dental implant having an internal connecting receiving space. An internally threaded insert is added into the internal connecting receiving space of the dental implant, and rotatably indexed. It is held by a fixing part forming an axial abutment opposing an extraction of the internally threaded insert out of the inner connection receiving space.

A dental implant having a central longitudinal axis at a bone-entry portion thereof is provided. The dental implant includes a threaded elongate fixture, at the bone-entry portion of the dental implant, shaped and sized for insertion into a bone of a subject, and a non-threaded emergence collar coronal to the fixture and smoother than the fixture. The emergence collar has a non-circular cross-section at least in a plane that is at least 1 millimeter coronal to the fixture and that is perpendicular to the longitudinal axis, the emergence collar and the fixture being formed of, and adjacently disposed along, a single piece of metal. Other applications are also described.

A method for manufacturing an implant including the steps of providing an implant element, the implant element made of a non-metallic material, depositing a thin layer of titanium-based material directly over an outer surface of the implant element, and forming a titanium-based structural body in direct contact with the thin layer by three-dimensional (3D) printing, the structural body being thicker than the thin layer of titanium-based material.

A drill-less dental implant to be implanted in a jaw bone comprises a screw thread comprising a core having a surface and a sharp tip and a spiral protrusion extending from the surface, wherein when the screw thread is rotationally screwed into the jaw bone, the sharp tip linearly penetrates the jaw bone, and a prosthesis support is attached to an upper edge of the screw thread and configured to support a dental prosthesis. A method of implanting the drill-less dental implant without drilling prior to the implantation is also provided.

A dental implant has a shank-shaped body with a truncoconical shape having a first distal end and a second proximal end; a housing for inserting and coupling a prosthetic element at the second proximal end; a tip at the first distal end; a helical threading having a cutting profile with a series of spiral turns about the shank-shaped body; a series of recesses each realised at a portion of a respective turn of a series of spiral turns of the helical threading. The helical threading starts directly from the end of the tip such that a first turn of the helical threading winds and extends about the tip and each recess has an entirely concave surface without corners or edges so that the recesses form a groove having a concave profile along the threading.
