  • Patent number: 11464555
    Abstract: This disclosure includes apparatus and methods to attach an orthopedic device to a bone. The method can comprise locating a baseplate on a glenoid of a patient, the base plate including at least a first fastener bore, creating a first post hole in the glenoid for locating a first fixation post, the first fixation post including a quasi-spherical head and a porous metal sleeve, and driving the first fixation post through the first fastener bore and into the first post hole. The porous metal sleeve can engage the first post hole and the quasi-spherical head can contact at least the first wall of the first fastener bore to removeably lock the quasi-spherical head to the baseplate. Driving the first fixation post can create an initial compression between the baseplate and the glenoid. The porous metal sleeve can receive bone ingrowth to maintain the initial compression.

  • Patent number: 10537373
    Abstract: An implant having a porous portion with a plurality of interconnected voids for receiving at least one injectable substance such that an injectable substance can elute from the porous portion. A syringe can be inserted into the at least one porous portion for administering the at least one injectable substance into the voids of the porous structure. The implant can be implanted with the at least one porous portion pre-loaded with the at least one injectable substance. The at least one porous portion can be loaded by inserting the syringe into the at least one porous portion after implanting the implant. The porous portion can be re-loaded with the syringe after the at least one injectable substance has eluted from the porous portion or replaced with a different injectable substance.

  • Patent number: 10485634
    Abstract: The present invention relates to a palatal anchor plate, which is fixedly installed to mid-palatal area (the roof of a mouth) and provides a rigid orthodontic anchorage for tooth movement, whereby the palatal anchor plate reduces a counteraction (movement of a tooth that is used as an anchorage), which occurs when a tooth is used as an orthodontic anchorage, and provides a rigid orthodontic anchorage for tooth movement in various directions, which is difficult to obtain when a tooth is used as an orthodontic anchorage.

  • Patent number: 10463580
    Abstract: A dental treatment method is provided. In this method, a tooth of a patient is extracted and prepared to provide a root part. A root canal in the extracted tooth is prepared and treated. A post of an abutment is fitted into the root canal to attach the root part to the abutment. The abutment having the root part is attached to a dental implant. With the root part attached to the abutment, periodontal connective tissue maintains the jaw bone associated with the extracted tooth, without significant hard tissue loss.

  • Patent number: 10441388
    Abstract: A device is provided for determining the angulation of an abutment for a dental implant. The device includes a conical projection extending from a housing. The conical projection is adapted for insertion into a hole in the dental implant. A rotary body is disposed in the housing and is rotatable among a plurality of different angular positions relative to the conical projection. A rod-shaped indicator is connected to the rotary body. The rotary body can be secured to the housing in one of the angular positions by a locking device. The device may be part of an assembly that includes an indicator device having a receiving opening for accommodating the conical projection and an indicator scale that includes a plurality of marked sectors corresponding to a plurality of predefined abutments, respectively. The location of the rod-shaped indicator relative to the marked sectors indicates the predefined abutment that should be selected.

  • Patent number: 10433937
    Abstract: A magic threader for a dental implant is disclosed, particularly, a dental implant capable of increasing coupling strength under a stable structure by specifying thickness of a thread portion, and pitch between thread portions in consideration of a difference in strength between titanium and bone to decrease stress of an alveolar bone by the thread portion and prevent damage to the alveolar bone and is capable of conducting compression of the thread portion for the alveolar bone in only one direction (direction A), minimizing compression of the thread portion for the alveolar bone in a direction B or a direction C inclined with respect to direction A, and maximizing stress dispersion by configuring the thread portion in a rectangular plate shape and specifying an angle of the screw thread in a specific numerical range.

  • Patent number: 10426531
    Abstract: The invention relates to a surgical bone screw comprising a shaft which has a bone thread and comprising a blocking means for interacting with a bone plate or for directly anchoring in the bone, in particular in the cortical bone. The surgical bone screw also comprises a screw head which has a rotationally symmetrical enveloping contour. The blocking means has a rib structure with at least one flank structure portion extending in the circumferential direction. According to the invention, the lateral surface of the enveloping contour has a constant or stepped concave progression, and the rib structure flank portion which extends in the circumferential direction is interrupted at least once in the circumferential direction, in particular multiple times, such that at least one elevation, in particular a plurality of elevations which are spaced in the circumferential direction, is produced in order to interact with the bone plate or with the bone in a blocking manner.

  • Patent number: 10413387
    Abstract: A threaded dental implant according to the present invention includes threads having a relatively shallow flank angle and a transition area that substantially reduces the width of the thread root. In some embodiments, each thread flange includes a transition point at which the flank angle transitions from a first angle to a second angle of lesser amount than the first angle. In these ways, the threaded dental implant includes a unique cored recess and provides various improvements over traditional threaded dental implants.
