  • Patent number: 10022232
    Abstract: A method of forming an implant to be implanted into living bone. The implant includes titanium. The method includes deforming at least a portion of a surface of the implant to produce a first micro-scale topography. The method further includes removing at least a portion of the surface to produce a second micro-scale topography superimposed on the first topography. The second micro-scale topography is generally less coarse than the first micro-scale topography. The method further includes adding a submicron topography superimposed on the first and second micro-scale topographies, the submicron topography including tube-like structures.

  • Patent number: 9962240
    Abstract: The present invention relates to a dental implant fixture, and more particularly, to a dental implant fixture which rotates about a central axis thereof, and thus is inserted into a bone tissue constituted by a cortical bone and a spongy bone to form an artificial tooth root, wherein the dental implant fixture includes a first portion, a second portion, and a third portion. The first portion is inserted into the cortical bone and has an outer surface with a first screw thread whereon first vertices and first valleys are alternately arranged. The second portion is disposed beneath the first portion and inserted into the spongy bone, has an outer surface with a second screw thread whereon second vertices and second valleys are alternately arranged. The distance between the adjacent second vertices of the second screw thread is larger than the distance between the adjacent first vertices of the first screw thread.

  • Patent number: 9833247
    Abstract: The invention relates to a surgical tool (1) for cutting a helical groove in a bone with a body (2) receiving at least a portion of a drive shaft (9) and a tool part (3) held on same comprising a functional element (5) that produces the groove in the bone by oscillating. The tool part (3) comprises a projecting, rotatable shaft (4) at whose end opposite the body (2) the pin (5) constituting the functional element extends through an aperture (8) out of the shaft (4) that, in order to remove material of the bone, can oscillate longitudinally. The shaft (4) is coupled in such a way with the drive shaft (9) that the latter exerts torque on the shaft (4) and the pin (5) at least indirectly, at least one wing (6) projecting radially from the shaft (4) that extends at a spacing beginning behind the pin (5) in the peripheral direction of the shaft (4) helically in the direction of the body (2).

  • Patent number: 9827074
    Abstract: A frictionally-retained detachable dental anchor device is provided for adjustably attaching a dental appliance with a tooth root or implant. The dental anchor device includes a cap secured in the dental appliance, an abutment attached with a tooth root or implant, and a compressible retention member with a first end in fixed attachment with the cap and a second end in snap engagement with the abutment via a frictionally-retained ball secured within a cavity of the abutment. The retention member is formed using a compressible material to allow the ball to compress and the retention member to flex while inserting the ball into the cavity. Additional friction-retained and fixed attachment configurations of the dental anchor device are provided, along with methods of securing a dental appliance in a subject's mouth by means of the friction-retained and fixed attachment dental anchor devices.
