The present invention relates to a fixation implant with an implant body which is made substantially of a ceramic material and has an external helical thread with more than one thread web and wherein a thread pitch angle of the external helical thread is in the range from 30° to 90°, and to the use thereof as an alloplastic bone implant, as an alloplastic dental implant, in production engineering, medical engineering, surgery, dental technology and/or implant technology.

A dental implant includes a generally cylindrical body, an interior bore, and a non-rotational feature. The generally cylindrical body has a main-central axis and is formed from cold-worked, high strength, commercially pure titanium having an ultimate tensile strength of at least about 900 MPa. The generally cylindrical body has a proximal portion and an opposing distal portion for anchoring the dental implant in bone of a patient. The interior bore is formed in the generally cylindrical body and has (i) a bore-central axis and (ii) a threaded portion for receiving a screw that is configured to removable hold an abutment in engagement with the dental implant. The non-rotational feature is configured to engage the abutment in a non-rotational fashion.

A driver tool for insertion and removal of a first part configured for threaded engagement in a corresponding threaded bore in a second part has a driving end portion of polygonal shape with multiple flats configured for engagement in a recess in the first part having a corresponding polygonal shape. Some or all of the flats have a respective grabbing feature or edge designed to grab or grip into the opposing surface of the recess to allow a greater amount of torque to be applied to the first part when the tool is rotated in the unthreading direction than when it is rotated in the opposite threading or insertion direction.

A bone expander contains: a body including a limitation section formed on an upper end of the body, a drill tip formed on a lower end of the body and extending from a bottom of the limitation section, a defining shoulder formed in an expanding umbrella shape and between the bottom of the limitation section and the drill tip, and multiple spiral ribs formed on the drill tip and the limitation section. The drill tip has multiple chip delivery grooves, and a respective chip delivery groove is defined between the drill tip and a respective spiral rib. The limitation section has multiple guide flutes corresponding to the drill tip and extending from the multiple chip delivery grooves, the drill tip has a cutting portion extending from a distal end thereof, and the cutting portion has a conical face formed thereon.

A dental cleaning system includes a cylindrical body with a first portion and a second portion. A cleaning portion is positioned within the second portion and includes a cavity to enable the cleaning portion to at least partially enclose a dental implant device. The cylindrical body rotates such that the cleaning portion therein rotates to clean at least a portion of the dental implant device. A projection extends outwardly from a surface of the cleaning portion such that the projection is positioned within the cavity. The projection removes debris from at least a portion of the dental implant device when the cylindrical body rotates. A plurality of cleaning protrusions extend outwardly from a sidewall of the cavity such that the cleaning protrusions at least partially circumscribe the projection. The cleaning protrusions remove the debris from at least a portion of the dental implant device when the cylindrical body rotates.

The present invention discloses a drill head structure for dental handpiece comprising a drill head main body, a screw nut and an adjusting ring. The drill head main body may be attached to a driving end of a dental handpiece so that the drill head main body may be driven by the dental handpiece to rotate at high speed. On the drill head main body is disposed a thread section. The screw nut is a hexagonal nut to be screwed to the thread section of the drill head main body. The adjustment ring has predetermined ring widths, and at a center thereof is disposed a hexagonal screw nut indent for the screw nut to be fitted into it. At a center of the adjustment ring is also disposed a threaded hole to be screwed to the foregoing thread section. The dental bone drill structure provided according to the present invention may achieve the purpose of controlling the drilling depth to which the drill head goes in and determine the drilling position.

A surgical method and tool for expanding an initial osteotomy (42) to receive a bone implant (44). An osteotome (22) having a tapered working end (28) is inserted into the initial osteotomy (42). The initial osteotomy (42) is enlarged by simultaneously rotating and pushing the working end (28) of the tapered osteotome (22) into the osteotomy (42). When rotated in one direction the burnishing edges (40) concentrate the pushing and rotational force in outward normal and tangential component forces against the interior surface of the osteotomy (42) to incrementally expand the osteotomy (42) with little to no removal of bone material (46). When rotated in the opposite direction the burnishing edges cut the interior surface of the osteotomy. Progressively larger tapered osteotomes (22) are used until an osteotomy (42) of predetermined size is achieved.

A method including fixing a dental drill template with a fixation pin including a rod and a head attached to the rod. The dental drill template can be fixed by inserting the rod into the drill template or a sleeve provided in the drill template such that a bearing surface of the head bears at least partially on the drill template. The rod has a shape of an essentially circular cylinder and extends from the bearing surface of the head at an essentially right angle. A diameter of the head at the bearing surface is larger than the diameter of the rod.

A dental implant whereby an osteotomy cavity is formed in jawbone and then a base member of the implant is positioned into the cavity. The base member serves as a platform to secure an abutment member of the implant that in turn receives a dental restoration, such as a crown or denture.

Embodiments of the present invention provide an osseointegrative implant and related tools, components and fabrication techniques for surgical bone fixation and dental restoration purposes. In one embodiment an all-ceramic single-stage threaded or press-fit implant is provided having finely detailed surface features formed by ceramic injection molding and/or spark plasma sintering of a powder compact or green body comprising finely powdered zirconia. In another embodiment a two-stage threaded implant is provided having an exterior shell or body formed substantially entirely of ceramic and/or CNT-reinforced ceramic composite material. The implant may include one or more frictionally anisotropic bone-engaging surfaces. In another embodiment a densely sintered ceramic implant is provided wherein, prior to sintering, the porous debound green body is exposed to ions and/or particles of silver, gold, titanium, zirconia, YSZ, α-tricalcium phosphate, hydroxyapatite, carbon, carbon nanotubes, and/or other particles which remain lodged in the implant surface after sintering. Optionally, at least the supragingival portions of an all-ceramic implant are configured to have high translucence in the visible light range. Optionally, at least the bone-engaging portions of an all-ceramic implant are coated with a fused layer of titanium oxide.
