A dental implant identification system of the non-contact type has a dental implant (260) and a non-contact tip (262) of a reader probe (263). The dental implant (260) has a non-contact RFID tag (264), which is cylindrical in shape, positioned immovably inside an open cylindrical cavity (266) within the main body of the dental implant (260), The non-contact tip (262) of the reader probe (263) includes, at its leading end, a reader antenna coil (268) (which is a transmitter receiver element in the form of a power coil), a coil positioning spring (270) and a reader positioning collar (272). The reader antenna coil (268) is electrically connected to, and receives its power through, wiring (273) from a match circuit (274) along which current flows. In use, the contact tip (262) of the powered on reader probe (263) is inserted through the opening of the cavity (266) of the dental implant (260) until further insertion is prevented by the reader positioning collar (272) becoming wedged ill the opening, and the tag antenna coil (276) and the reader antenna coil (268) are magnetic field coupled. The non-contact RFID tag (264) is passively powered by electromagnetic wave transmissions from the reader antenna coil (268) of the reader probe and received by the tag antenna coil (276).

A dental implant for implantation in the jawbone for the purpose of fastening a superstructure. The implant includes an implant body that extends between a coronal and an apical end and which defines an enossal outer surface. The implant body defines a cavity that is open coronally as well as at least one exit opening from an inside to the enossal outer surface. An outer thread is shaped on the implant body. A thermoplastic element is moreover present in the solid condition and is arranged in the cavity or introducible into the cavity, wherein the thermoplastic element can be brought into an at least partly flowable condition by way of applying a pressing force, which is directed apically into the cavity, and mechanical oscillations and can be pressed through the at least one exit opening into surrounding tissue on account of the pressing force.

A dental implant includes an implant body with a coronally open cavity as well as at least one exit opening from an inside to the enossal outer surface. A thermoplastic element in the solid condition is arranged in the cavity or is introducible into the cavity and can be brought into an at least partly flowable condition by way of applying a pressing force, which is directed apically into the cavity, and mechanical oscillations and in this condition at least a share of the flowable material of the thermoplastic element can be pressed through the at least one exit opening into surrounding bone tissue on account of the pressing force, when the implant body is arranged in an opening in the bone tissue and the enossal outer surface is in contact with the bone tissue.

An orthopaedic implant includes an internal fixation device. The internal fixation device includes: an exterior surface; a threaded section including a reservoir and at least one threaded section channel fluidly communicating the reservoir with the exterior surface, each threaded section channel having an interior diameter and a length which is greater than the interior diameter; a head including a head channel fluidly communicating the reservoir with an exterior surface of the head, a channel diameter of the head channel being respectively larger than a largest interior diameter of each threaded section channel, the channel diameter of the head channel being the same as a large interior diameter of the reservoir; and a continuously tapering inner surface between the head channel and the reservoir.

Artificial salivary gland devices and assemblies are provided. The present disclosure provides artificial salivary pump/gland devices and assemblies, and related methods of use. One embodiment utilizes the interstitial/marrow fluid reservoir within the underlying mandibular or maxillary bone as a source for replacement saliva. The salivary pump/assembly, which is implantable in the mandibular or maxillary bone as a dental implant and driven by incidental tooth contact and masticatory forces, harvests interstitial/marrow fluid and treats it via semi-permeable membrane technology and soluble particles as a continuously available saliva replacement. Masticatory forces and tooth contact power the pump to both harvest interstitial/marrow fluid and drive flow through a bed of ion-exchange resins and/or soluble particles to adjust fluid chemistry providing a continuously available saliva-like solution. Exemplary devices and assemblies can also be utilized to introduce beneficial bacteria into the oral cavity and/or be utilized as a delivery system for drugs/therapeutic agents.

A bone implant includes: a body including a connection end and a drill end respectively on two ends thereof, with the body including a plurality of engagement sections between the connection end and the drill end, with a disengagement prevention section provided between two adjacent engagement sections, with each engagement section including a drilling thread disposed on an outer periphery of the body, with the drilling threads of the engagement sections having the same thread direction, with the disengagement prevention section including a coupling section on the outer periphery of the body, and with the disengagement prevention section having a maximum outer diameter smaller than a minimum outer diameter of each engagement section between the disengagement prevention section and the connection end; and an abutment seat mounted on the connection end of the body, with the abutment seat including a keying recess.

A dental implant including an implant body having a top surface, and at least one non-annular cutaway portion longitudinally extending downwardly from the top surface along one side of the body and outwardly to the periphery, and a method for making the implant. The implant body preferably includes a body portion and a head portion integrally formed with the body portion, the body portion has a periphery and the head portion has a non-circular periphery, and the periphery of the head portion is smaller than the periphery of the body portion.

The present invention relates to a dental implant fixture for implanting a correction tooth as a dental implant into alveolar bone. Particularly, the dental implant fixture has self-vertical drilling, self-horizontal drilling, self-cutting, self-condensing, and self-direction changing functions. The dental implant fixture can increase primary stability and penetration performance, has good ability to correct implantation errors, and can minimize the need for drilling that increases the probability of error or failure.

Silver and/or zinc ion releasing implants, systems and method of operating, inserting and activating/inactivating them are described. In some variations the implant is configured as a bone implant that includes a bone-screw or intramedullary rod like body configured to receive a treatment cartridge having a plurality of ion-releasing members configured as an anode that can controllably engage with a catheter to turn galvanic release of ions on/off as desired. These devices may be configured to release silver ions (and/or zinc ions) above a predetermined level for a predetermined period of time and may maintain a concentration of ions over a relatively large volume of tissue. The ion-releasing members may be configured to reduce or prevent implant movement.

An implant or endoprosthesis suitable to be implanted in human or animal tissue includes two (or more than two) parts to be joined in situ. Each one of the parts includes a joining location, the two joining locations facing each other when the device parts are positioned for being joined together, wherein one of the joining locations includes a material which is liquefiable by mechanical vibration and the other one of the joining locations includes a material which is not liquefiable by mechanical vibration and a structure (e.g. undercut cavities or protrusions) suitable for forming a positive fit connection with the liquefiable material. The joining process is effected by pressing the two device parts against each other and by applying ultrasonic vibration to one of the device parts when the two parts are positioned relative to each other such that the two joining locations are in contact with each other.
