A dental implant fixture is proposed. The dental implant fixture is configured to be implanted in a straight alveolar bone perforation hole without inclination, and includes: a head to which an abutment is coupled; a self-tapping portion extending from the head and having a ridge diameter of cutting blades that is larger than an inner diameter of the alveolar bone perforation hole; and a guide extending from the self-tapping portion and having a diameter corresponding to the inner diameter of the alveolar bone perforation hole.

A temporary cylinder for snap-in retention with an elongate dental implant includes an elongate body extending from a first end to a second end, the elongate body being generally cylindrical and having an upper portion and a lower engagement portion and the temporary cylinder's lower engagement portion includes a male irregular hexagonal plug, and wherein the dental implant includes a female regular hexagonal socket, and wherein the male irregular hexagonal plug and the female regular hexagonal socket are configured for inter-engagement with each other, and the fitment of the irregular hexagonal plug and regular hexagonal socket together with one another results in a frictional fit when inter-engaged.

The present application relates to a medical light diffusion implant and, more specifically, to a functional implant to emit medical lights so as to induce rapid recovery after an implantation. According to the present invention, A medical light diffusion implant, comprising a socket including a space therein, capable of being fixed to a living body and a crown coupled with the socket so as to seal the socket, wherein the socket is transmittable by lights, and comprises a light source unit included at an inner space of the socket and the crown coupled to each other, to emit the lights.

A bony screw with a movable bracket arm includes a head and a shank extending therefrom. The shank has an upper portion, a threaded lower portion adjacent to the upper portion, thereby defining a junction, and a self-tapping tip. An annular flange is disposed at the junction between the upper portion and the threaded lower portion of the shank, and is contiguous with respect to each of the upper and threaded lower portions, and has a peripheral surface with a diameter greater than a diameter of the head and greater than a diameter of the upper portion, thus defining a stop between the upper and threaded lower portions. A first end of a bracket arm is pivotally secured to the upper portion of the shank, and an opposed second end of the bracket arm defines a loop.

A medical implant and a method of implanting a medical implant are described. The medical implant can be elongate and for fixation in a patient, and 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. The apical portion can have 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 a method of implanting a medical implant, an apical part can be affixed in the zygomatic bone, and a coronal part can be positioned outside the maxilla in the mucous membrane.

The invention is directed to a new dental implant and associated parts that allow for insertion in narrow areas of the alveolar bone. Characteristics of the body of the implant allow for comfortable insertion in narrow bone clefts provided by its smooth narrow sections. The implant provides an alternative to complex and time consuming surgical processes involving bone regeneration and/or grafting.

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 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.

The present invention relates to a prosthetic assembly (1, 10, 100) comprising a prosthetic component (2, 20, 200) and a retention screw (6, 60, 600) with an interference geometry (5, 50, 500) designed to allow relative rotation, limit relative longitudinal motion and inseparably join the prosthetic component (2, 20, 200) and the retention screw (6, 60, 600). The interference geometry (5, 50, 500) can be in the form of a ring attached to the retention screw (6) in a portion of the body of this screw (6) having a smaller diameter, or in the form of one or more inwardly folded flaps integrated in the prosthetic component (20) and diametrically distributed around the base thereof, or in the form of a uniform, tapered and hollow projection of the lower portion of the prosthetic element (200). The invention further relates to a method for producing the disclosed prosthetic assembly (1, 10, 100), including the following steps: forming a prosthetic component (2, 20, 200) having a central hole (8, 80) for receiving the retention screw (6, 60, 600), forming a retention screw (6, 60, 600), the body of which has a portion having a smaller diameter (62, 602), inserting the retention screw (6, 60, 600) into the central hole (8, 80) of the prosthetic component (2, 20, 200), and forming an interference geometry (5, 50, 500) between the base of the prosthetic component (2, 20, 200) and the body of the retention screw (6, 60, 600).

Dental implants, dental abutments, and dental systems are disclosed. A dental implant can include an implant body having a longitudinal axis, a coronal end, and an apical end. An internal bore can be provided within the implant body, and can have a coronal end, adjacent to the coronal end of the implant body, and an apical end. The internal bore can include a first internally facing surface, extending from the coronal end of the internal bore towards the apical end of the internal bore, at least a portion of which tapers inwardly towards the apical end of the internal bore. The internal bore can further include an internally threaded portion positioned between an apical end of the first internally facing surface and the apical end of the internal bore. A dental abutment can be configured to engage with the dental implant.
