  • Patent number: 10772709
    Abstract: The present invention relates to a dental implant having at least one but preferably a plurality of split fins that are vertically spaced along the vertical axis of the body portion of the implant. These split fins hold the body portion of a dental implant stationary within the patient's jaw by engaging the patient's jawbone and promoting osseointegration—the growth bone around and on the surface of the implant. Each split fin has a first end that is vertically spaced from a second end along the implant body's vertical axis such that the split fin extends from the first end and around the body's circumference along an inclined plane until it terminates at the second end so that the split fin creates a single spiral that extends around the entire circumference of the body portion of the implant.

  • Patent number: 10729519
    Abstract: There is provided an implant having a slack prevention function by an eccentric fitting structure. An engaging shaft 53, which is decentered with a screw shaft 52, is provided at the end of an abutment screw 5, and is engaged with an engaging hole 45 provided in the bottom of a screw hole 44, into which an abutment screw 5 is screwed, and thus, the screw shaft 52 is inclined to and eccentric from the screw hole 44. Thereby, the screw shaft 52 comes to be strongly pressed partially in a circumferential direction toward the screw hole 44, so that internal stress in the horizontal direction is accumulated on the screw shaft 52. The screw 5 is threaded with maintaining prevailing torque caused by the internal stress, which enables the screw 5 to be fastened to the right position.

  • Patent number: 9713513
    Abstract: The subject matter of the disclosure is, in one example, a dental implant having a corpus, an external thread attached on the endosteal area of the corpus, and a post accommodation formed in the inside of the corpus. Providing a dental implant that can be anchored well in the jaw is achieved by forming a recess on the endosteal end of the corpus oriented coaxially to the longitudinal axis of the corpus.

  • Patent number: 9687327
    Abstract: The present invention includes apparatuses and methods for making a final hybrid prosthesis to be attached to one or more dental implants. One preferred method includes the step of making a temporary hybrid prosthesis and at about the same time also making a duplicate temporary hybrid prosthesis. The duplicate temporary hybrid prosthesis permits the final hybrid prosthesis to be made with fewer visits to a restorative dentist and with less dental laboratory time than is currently needed when making a final hybrid prosthesis.

  • Patent number: 9687321
    Abstract: A dental-implant having a first implant part provided for being inserted into a jawbone and having a second implant part associated therewith, provided for fixing a dental prosthetic piece, the implant parts being mechanically connectable to each other via a connection pin which is formed onto one of the implant parts and which can be pushed into a receiving channel provided in the other implant part, and the outer cross-section of the connection pin and, matching said cross-section, the inner cross-section of the receiving channel associated therewith, each being designed in an indexing area as a polygon, shall enable a particularly simple mounting. For this purpose, the connection pin has at least two sections in the indexing area, the outer edges of the polygon being rounded more strongly in a first, end-side section than in a second section.

  • Patent number: 9681930
    Abstract: Implants for anchoring within bone are provided herein. An implant may include at least one thread extending around a core in a plurality of turns from the coronal region to the apical region. The thread(s) has a thread outer diameter that may define a cylindrical portion, wherein the thread outer diameter remains constant for more than one turn around the core, and define a conical portion, wherein the thread outer diameter decreases at a thread diameter decrease rate in the apical direction. The thread(s) may have a plurality of notches spaced radially and longitudinally from one another. The notches may be partially notched to reflect a portion of a semi-spherical surface and partially notched to reflect a portion of a semi-cylindrical surface.

  • Patent number: 9655699
    Abstract: An artificial teethridge has an arched top and an arched bottom. The top and the bottom of the artificial teethridge are curved toward the same direction. The thickness of the artificial teethridge is relatively thicker at central part and gradually becomes thinner toward two lateral sides. A fang is formed integrally on the top of the artificial teethridge. The artificial teethridge, the fang and a prosthesis are an integral structure, whereby the artificial teethridge, the fang and the prosthesis form a mechanical conduction structure. The bottom surface of the artificial teethridge has a complementary structure which can be tightly matched and fixed on each point of the top surface of the alveolar bone without any gap. A dental neck is formed integrally between the artificial teethridge and prosthesis, which is formed in a waisted shape that is narrower at middle section and gradually becomes wider toward to two terminal sections.
