An anchor to be screwed into a hole and self-lock therein with high initial stability. The anchor has an aggressively-threaded, self-tapping apical end. A central region of the anchor is formed with a plurality of helical flutes and intervening lands. Each land carries a condensing edge. The condensing edges are configured to apply a circumferentially sweeping compressive strain to the interior surface of the host material while the anchor is being screwed into position. A coronal end of the anchor includes a corking feature to mitigate mushrooming around the perimeter of the hole. A helical groove intersects the condensing edges and flutes. The helical groove has a variable pitch and a decreasing depth which functions to squeeze and displace trapped host material thereby enhancing stability and other benefits. In bone applications, the groove hosts material chips which promote and enhance healing.

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 dental implant includes a body and a thread. The body has a central axis, a coronal end, and an apical end. The thread is coupled to the body. The thread has a coronal facing surface, an apical facing surface, and a crest surface positioned between the coronal facing surface and the apical facing surface. The coronal facing surface of the thread has a plurality of steps formed therein.

The present invention relates to a dental implant analog, an implant analog kit comprising the dental implant analog, the combination of a physical model of a set of a patient's teeth and the dental implant analog and a method of positioning a dental implant analog into a physical model of a set of a patient's teeth.

Disclosed is an implant fixture. The fixture of a dental implant according to the present invention includes a fixture body in which a screw portion is formed in a spiral shape along an outer wall and an abutment insertion groove inserted with an abutment is recessed in a longitudinal direction at an upper end, an abutment rotation stopping portion which is formed in a shape in which at least a part of the inner wall of the fixture body is shape-fitted to the outer wall of the abutment and stops a relative rotation to the fixture body of the abutment, and a tool coupling portion which is provided in the fixture body adjacently to the abutment rotation stopping portion in an upper region of the abutment rotation stopping portion and detachably coupled with a rotary tool rotating the fixture body.

A denture attachment is provided. More particularly, a denture attachment is such that a user can detachably fasten a first fastening part coupled to a denture to a second fastening part placed on top of a natural tooth's root or implant fixture by a simple operation, and furthermore, even when occlusal force is continuously applied to the denture, the applied force can be buffered by an elastic rib structure of the attachment itself. Consequently, it is possible to extend not only the lifespan of the attachment, but also the lifespan of the implant fixture or natural tooth's root, and to provide superior performance with a significantly smaller volume than existing attachments, while providing excellent durability.

Highly self-tapping dental implant system with hybrid cone type connection and interlocking rails, which allows high insertion (or removal) torque and double parallel cone locking between the implant, prosthetic abutment and internal screw, even in its 3.0 mm diameter embodiment, and gives the whole system high primary and secondary stability, optimal watertightness thanks to the double cone sealing, as well as predictable long-term fixation of the dental prosthesis on the implant.

A dental implant including a first, apical portion for inserting into bone, and a second, top-side portion, starting at a level of bone surface and higher, including a stricture of the dental implant diameter, relative to a diameter of the top-side portion, for at least part of the top-side portion. Related apparatus and methods are also described.

According to an aspect of some embodiments there is provided a bone anchor including an elongated core having a tip at a distal end and coupled to a head at a proximal end, and a segmented helical thread defining one or more gaps therein, each gap defining at least a trailing wall, the trailing wall having a cutting surface including at least one cutting edge. The bone cutting surface and the cutting edge configured to cut bone and guide bone fragments radially inwards. According to an aspect of some embodiments there is further provided a bone anchor kit and a method for implanting the bone anchor in bone.
