A dental prosthesis system includes a dental implant having a dental implant fixture and an internal locking collar extending upwardly from the dental implant fixture. The internal locking collar defines a central bore extending downwardly into the dental implant fixture. An abutment for cement has a base surface for placement against the dental implant, which defines a central hole aligned with the central bore. A securing mechanism secures the abutment for cement to the dental implant. The securing mechanism including an expansion locking system disposed through the central hole and within the bore. A portion of the expansion locking system is expandable outwardly so as to lock the abutment for cement to the dental implant fixture.

A set of components for dental prosthetic restoration includes a ceramic dental implant having an internal connecting receiving space. An internally threaded insert is added into the internal connecting receiving space of the dental implant, and rotatably indexed. It is held by a fixing part forming an axial abutment opposing an extraction of the internally threaded insert out of the inner connection receiving space.

Dental implant embodiments comprising one or more non-annular cutaways from a portion of the crown are described. In some embodiments, cutaways, which are implantable beneath the bone line, are orientable during implantation by reference to a dental implant positioning tool to which the dental implant is mated in a known orientation. Mating, in some embodiments, is secured by a detent system which reversibly interlocks the positioning tool and the implant. In some embodiments, a surface of a cutaway is provided with protrusions which stimulate bone regrowth into the volume which the remainder of the cutaway provides.

The present invention discloses a dental implant (30; 130; 230; 330; 430) for preserving soft tissue and promoting bone growth, including an elongated implant body having a coronal end portion (31; 131; 431) and an apical end portion (32; 132; 332; 432); an external thread (40; 140; 240; 440); a flute arrangement (50; 150; 350; 450) having at least one helical flute having a depth; in which the apical end portion forms a blunt tip (39; 139; 339), and in which the helical flute spirals in opposite direction to the external thread, and the flute exits on the face of the blunt tip.

A dental implant for insertion into bone within a patient's mouth comprises a body and a scannable code. The body includes a bone-engaging exterior surface, an anti-rotational feature for non-rotationally mating with an abutment, and an upper region. The upper region includes an upper surface for engaging the abutment. The scannable code on the upper surface provides information concerning the dental implant. The information includes at least two features of the dental implant.

A medical implant includes a base portion configured for implantation into a bone of a patient. The base portion is formed from an electrically insulating and biocompatible base material with retaining features on an outer surface of the base portion for gripping the bone in the patient. A plurality of titanium bands is positioned along the outer surface of the base portion.

A damping dental post key configured to implant a dental root post for restoration of a tooth is described. The dental post key includes a body for handling and a post carrier having a key shape with respect to a head portion of the dental root post. During implantation of the dental post, rotation of the body compresses a set of springs in contact with the post carrier reducing a reaction force to a tooth root. In this way a limited force will be applied and a root fracture can be prevented. Further, the dental post key can be configured to have a fixed movement in a counterclockwise direction to remove the dental post and a free quarter-cycle movement with effort in a clockwise direction.

A novel screw-fastening assembly having anti-loosening capabilities includes a first and a second screw elements 11,12 adapted to be screw-fastened; the element 12 includes a recess R, the recess being open toward the element 11; and the element 11 includes an protrusion P, the protrusion being introduced into the recess R in a fastened state. The recess R has an inner peripheral surface formed in a cylindrical shape that is straight along the axial direction. The protrusion P is shaped as a circular column or cylinder having a maximum-diameter portion at one location along the axial direction. The protrusion P and the recess R are eccentric relative to each other such that the maximum-diameter portion of the protrusion and the inner peripheral surface of the recess are in pressure contact only along part of their circumference in the fastened state. The maximum-diameter portion is spaced apart from the base end of the protrusion P by a predetermined distance so as to allow the protrusion to move forward and backward along the axial direction relative to the recess R with the maximum-diameter portion being in pressure contact with the inner peripheral surface of the recess R only along part of their circumference.

A dental tool for resurfacing thread forms of a dental implant is disclosed. The tool includes a main body having a cylindrical member with a slot. A blade having a head is inserted in the slot to orient the head to protrude from the interior surface of the cylindrical member of the main body. The main body may be rotated into traversing a thread form of the implant. A compression sleeve is inserted over the main body. The compression sleeve has an open position and a closed position to hold the blade in the slot. The compression sleeve may be flexed by relative movement of the blades to resurface threads of a tapered dental implant.

The present invention relates to a dental implant (100, 100′, 500) and to a kit for said dental implant. In order to provide dental implants (100, 100′, 500) which meet the general requirements for a successful implantation and use and which can be easily adapted to bone variations and implant offerings, it is proposed according to the invention that the dental implant (100, 100′, 500) comprises a ceramic base body (130, 530), a ceramic abutment (120, 120′, 520), a ceramic tooth structure (110), and/or a connector (1, 1′, 1″, 5) for connecting of base body (130, 530), abutment (120, 120′, 520) and/or tooth structure (110) to each other, and a bushing body (6), which is at least in a final assembly state (E) of the dental implant (100, 100′, 500) received at least partly in the base body (130, 530), in the abutment (120, 120′, 520) and/or in the tooth structure (110) or surrounds the connector (1, 1′, 1″, 5) at least in sections.
