A ceramic implant which has a ceramic, endosseous surface region that is intended to be embedded into the bone tissue and that is made of a ceramic material. The surface region has at least one first zone having a surface modification, in which first zone the surface is roughened or porous, and at least one second zone, in which the surface is not roughened or porous.

invention further relates to a method for producing a dental prosthesis. In this method the dental prosthesis block is provided and the dental prosthesis is produced by removing material from the dental prosthesis forming block by means of a CAD/CAM method, such that the pin forms part of the finished dental prosthesis.

Disclosed is an implant fixture. The fixture of a dental implant according to the present invention includes a fixture body in which a screw portion is formed in a spiral shape along an outer wall and an abutment insertion groove inserted with an abutment is recessed in a longitudinal direction at an upper end, an abutment rotation stopping portion which is formed in a shape in which at least a part of the inner wall of the fixture body is shape-fitted to the outer wall of the abutment and stops a relative rotation to the fixture body of the abutment, and a tool coupling portion which is provided in the fixture body adjacently to the abutment rotation stopping portion in an upper region of the abutment rotation stopping portion and detachably coupled with a rotary tool rotating the fixture body.

A dental implant including a core; at least one screw thread; a first and second region; a central axis; the surface of the core defining an angle with the central axis in the first region and with the central axis in the second region; and the surface of the screw thread defining an angle with the central axis in the first region and with the central axis in the second region. The diameter of the core decreases at a rate in the first region towards the apical end such that the core defining angle is greater than the screw thread defining angle, and the diameter of the core decreases at a rate in the second region towards the apical end such that the core defining angle is the same as the screw thread defining angle. Furthermore, an implant including at least one helical chamber including a depth and length.

The present invention enables modification of an intraosseous implant device that is not only biologically non-inert, but can stimulate bone and vascular growth; decrease localized inflammation; and fight local infections. The method of the present invention provides a fiber with any of the following modifications: (1) Nanofiber with PDGF, (2) Nanofiber with PDGF+BMP2, and (3) Nanofiber with BMP2 and Ag. Nanofiber can be modified with other growth factors that have been shown to improve bone growth and maturationBMP and PDGF being the most common. Nanofiber can be applied on the surface of the implant in several ways. First, a spiral micro-notching can be applied on the implant in the same direction as the threads with the nanofibers embedded into the notches. Second, the entire surface of the implant may be coated with a mesh of nanofibers. Third, it can be a combination of both embedding and notching.

A dental implant for insertion into bone within a patient's mouth comprises a body and a scannable code. The body includes a bone-engaging exterior surface, an anti-rotational feature for non-rotationally mating with an abutment, and an upper region. The upper region includes an upper surface for engaging the abutment. The scannable code on the upper surface provides information concerning the dental implant. The information includes at least two features of the dental implant.

The secondary part (17) according to the invention, for securing on and/or in a dental implant, is suitable for receiving a tertiary part. The secondary part (17) comprises a secondary-part body (22) with a recess (21) on the inside, and a secondary-part screw (20) receiveable or received in the recess. The secondary part (17) has a screwing-in mechanism in the form of a contour for receiving a screwing-in tool for screwing the dental implant, connected to the secondary part (17), into a jawbone.

A biological tissue rootage face (30) capable of closely bonding to a biological tissue (H, S) is composed of a biocompatible material and has numerous fingertip-shaped microvilli (41). The microvilli (41) have tip diameters in the order of nanometers. An implant (1) has the biological tissue rootage face (30) on a surface (11, 24) configured to root into a biological tissue (H, S). In a method for forming the biological tissue rootage face (30), a surface of a biocompatible material is subjected to laser nonthermal processing carried out by emitting a laser beam in air, to form numerous fingertip-shaped microvilli (41). The laser beam is a laser beam of an ultrashort pulse laser.

A medical implant and a method of implanting a medical implant are disclosed. In some embodiments, the medical implant can include an apical bone anchoring portion for bone apposition and an unthreaded coronal portion. The coronal portion can have a length (L.sub.2) exceeding or equaling a length (L.sub.1) of the apical portion. Further, in some embodiments, the apical portion has a maximum outer diameter (D.sub.1) that is equal to or larger than a maximum outer diameter (D.sub.2) of the coronal portion. In some embodiments of the method, an apical part of an implant is affixed in the zygomatic bone and a coronal part is positioned outside the maxilla in the mucous membrane.

The present invention relates to endosseous implants and in particular, to screw form dental implants for implanting within bone. The bone implant is configured to be a self-drilling bone implant that is adept at condensing, collecting and distributing bone along all of the implant's surface and within the implantation site, to significantly increase the bone implant contact surface. The implant is configured to have a coronal portion and a body portion that are continuous with one another. The coronal portion is configured to have a smaller overall diameter than the overall diameter of said body portion. The body portion is fit with threading that facilitates the self-drilling and bone collection properties when the implant is rotates in both the clockwise and counterclockwise directions.
