A dental implant has a core manufactured in metal and a sleeve having an internal wall and nested by sliding on an upper part of the core in such a manner that the internal wall is located faced to that upper part of the core, which sleeve is manufactured from ceramic or Peek, a gap being left between the core and the internal wall of the sleeve in such a manner that an adhesive layer can be lodged in a space formed by the presence of that gap, wherein said gap has a distance situated between 5 and 30 μm, in particular between 10 and 20 μm.

The present disclosure relates to a method for removing residual acid of implant that has been surface treated using acid, the method including thermal decomposition step of thermally decomposing and removing the acid remaining on the implant; base treatment step of treating the acid remaining on the implant with base, thereby neutralizing and removing the acid; and washing step of washing and removing the acid and the base remaining on the implant with washing water.

According to the present disclosure, the acid remaining on the surface of the fixture can be effectively removed, and thus there is an effect of preventing the problem of bone loss that may occur near the placed implant.

A dental implant includes a body and a threaded surface. The body has an upper portion, a middle portion, and a lower portion. The upper portion of the body includes a generally cylindrical region. The lower portion of the body includes a generally inwardly tapered region. The middle portion of the body includes an outwardly extending bulge. A maximum outer diameter of the bulge is greater than (i) a maximum outer diameter of the upper portion and (ii) a maximum outer diameter of the lower portion. The threaded surface is on the body within at least the upper portion of the body, the bulge, and the lower portion of the body.

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.

An implant for insertion within a maxillofacial bone of a patient, for example a dental implant, including a three-dimensional stabilization thread form extending along at least a portion of the implant body in a first helical direction, and one or more grooves or channels extending through the three-dimensional stabilization thread form in a generally opposite second helical direction, whereby one or more cutting edges are formed at the intersection of the one or more grooves or channels with the three-dimensional stabilization thread form.

Disclosed is a low-cost, scalable and highly repeatable approach to fabricate polystyrene films with three-dimensional nanopyramids on the surface. The nanopyramids have tubable aspect ratio and anti-bacterial performance. The effectiveness of the nanopyramids on bacterial and fungi growth inhibition and the role of nanostructure aspect ratio are confirmed via through scanning electron microscopy and confocal laser scanning microscopy. The results show an excellent antibacterial performance with more than 90% reduction in E. coli population in all nanopyramid samples after a 168-hr prolonged incubation time. The nanopyramid film developed here can be used for the clinical and commercial applications to prevent the growth of pathogenic bacteria on various surfaces.

An abutment is provided with a screw access hole and a slot in its sidewall adapted to allow a driver to access a screw in the screw access hole at an angle relative to a longitudinal axis of the screw. The abutment may include a screw seat and may be connected to an implant via a screw in the screw seat. A prosthesis, which may include a driver access channel that has a diameter less than the outer diameter of the drive portion of the screw, may be placed over the abutment. Methods of making a dental prosthesis and methods of attaching and removing the dental prosthesis from the implant are also disclosed.

An external drive apparatus for bendable collar implants includes a male fastener and a female driver. The male fastener is constructed as a rigid and integral unity including an implant screw, a collar, and a male screw-top drive. The female driver supports a female screw-top drive. The female driver is configured for application of an implantation torque to the implant screw via the male screw-top drive which is disposed distally away from the collar.

A dental implant (1), in particular for insertion into bone tissue of a patient, comprising: a core body (2) having an apical end (4), a coronal end (6), and an outer surface (8) extending along a longitudinal direction between said apical end (4) and said coronal end (6); and at least one thread (12) located on at least a threaded portion of said outer surface (8), should have superior properties regarding primary and secondary stability. According to the invention this is achieved in that the core body (2) comprises a core shaped zone (22), preferably next to said coronal end (6), in which core shaped zone (22) the cross-section of said core body (2) has a number of main directions in which the radius measuring the distance between the center (50) of the cross section and its outer contour takes a relative maximum value and thus a higher value than in neighboring orientations, a core circular zone (20), preferably next to said apical end (4), in which core circular zone (20) the cross-section of said core body (2) is basically circularly shaped, and, as seen in said longitudinal direction, a transition zone (26) positioned between said core shaped zone (22) and said core circular zone (20), in which transition zone (26) the geometry of the cross-section of said core body (2), as a function of a parameter characteristic for a coordinate in said longitudinal direction, changes continuously from a basically circular shape next to said core circular zone (20) to a shape in which the cross-section of said core body (2) corresponds to the shape of the cross section in said core shaped zone (32). The invention further relates to an insertion tool (200) for inserting a dental implant (1, 201, 401) into bone tissue of a patient. Moreover, the invention relates to a combination of such a dental implant (1, 201, 401) and such an insertion tool (200).

A system can be configured to record a position and orientation of a dental component. The system can include a coping and a replica. The coping can include an anti/rotational feature that is configured to mate with an anti-rotational feature of a dental component. The coping can also include an orientation feature that is configured to convey the orientation of the dental component. The replica can include a first anti-rotational feature that corresponds to the anti-rotational feature of the dental component. The replica can also include a second anti-rotational feature that does not correspond to the anti-rotational feature of the dental component.
