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.

A dental superstructure defines a channel formation for the fixing element of a dental superstructure. The superstructure (1) is fixed to an implantation (3) integrated in the jaw bone by means of a fixing element (2). A channel (7) is formed in the superstructure (1). The axis line (8) of the channel (7) is shaped to follow an arc (9) whose radii pointing to given points of the axis line (8) diverge from the plane of the arc (9) by 0-5. The channel (7) is shaped in such a manner that the sections determined by the planes perpendicular to its axis line (8) are circles with the same diameter with their centers on the axis line (8). In the method according to the invention a computer controlled device is used for forming the channel.

Disclosed is a surface processing method for a dental implant, the surface processing method including: (a) laser-processing a surface of an implant; (b) etching the laser-processed surface of the implant; and (c) washing the etched implant, wherein a macro surface including one or more first grooves is formed at the surface of the implant by step (a), a micro surface including one or more second grooves is formed at the surface of the implant by step (b), an outer circumferential surface of the implant includes a top portion and a bottom portion, and at least one of an average width and an average depth of the first grooves is formed to be greater at the top portion of the outer circumferential surface of the implant than at the bottom portion of the outer circumferential surface of the implant.

The present invention relates to a membrane for implant, which is a pocket type. In the present invention, the storage space (50) for storing the artificial bone (4) is formed inside the membrane and porous holes (31) is formed at the rear portion (30) in contact with the alveolar bone, thereby facilitating the integration with and regeneration of the alveolar bone tissue in contact with the grafted artificial bone and preventing the deviation of the artificial bone during the procedure and the regeneration afterwards for effective implant.

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.

A multi-segment dental implant may include an apical segment including apical external threading at least partially surrounding the apical segment, wherein the apical segment defines a connection aperture including an coronal shoulder. The multi-segment dental implant may include a coronal segment including coronal external threading at least partially surrounding the coronal segment and terminating in a non-knife-edge apical skirt. The multi-segment dental implant may include a connector constructed and arranged to connect the apical segment and the coronal segment.

Provided is a non-invasive blood measuring device comprising: a fixture which in part or in whole is buried in bone tissue of a patient; an abutment provided in a space inside the fixture; a sensing unit including biosensors for measuring a substance in the blood; a filter through which the substance in the blood to be measured is passed through; and an outcall unit.

A system of components or implements for easily and precisely installing a dental implant, and a method of installing the dental implant, within a patient's jaw, is disclosed. The system comprises a rotary cutter guide and a rotary cutter. Orthogonal slots are defined within the rotary cutter guide so as to precisely position the rotary cutter within the rotary cutter guide as well as to permit the rotary cutter to form slots within a patient's jaw so as to accommodate winged members of a winged dental implant. A method of installation is also disclosed, and the system and method may be utilized in conjunction with the installation of both a single winged implant or a dual winged implant wherein the two winged implants are connected together by means of a connecting bar or plate.

A root implant includes a body portion, a drilling portion formed on the body portion, a positioning hole formed opposite to the drilling portion, and a thread portion spiraled on the body portion. The body portion and the coarse thread have respective first openings and second openings spaced apart by equal distances. The first openings and second openings accommodate accretions grown from the alveolar bone when the root implant interfaces with the alveolar bone. The body portion and the coarse thread includes first joint sections and second joint sections formed between any two of the first openings and the second openings respectively to allow the accretions to clamber and link together to provide a tight combination between the root implant and the alveolar bone, preventing the loosening problem caused by an external force and promoting a positioning effect of the root implant.

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.
