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.

Disclosed are a fixture for a dental implant and an implant system comprising the same. The implant system of the present inventive concept comprises: a first fixture having a first body part and a first continuous screw part which is formed in a spiral around the outer circumferential surface of the first body part and is formed continuously without a break; and a second fixture having a second body part that is identical to the first body part, and a second continuous screw part which is formed in a spiral around the outer circumferential surface of the second body part and which has an outer diameter that differs from that of the first continuous screw part. The present inventive concept allows implant operations to be carried out in a more straightforward fashion than hitherto since, even if initial fixture placement fails, a subsequent fixture can be placed straight away without any further drilling work.

An implantation kit including a rotational osteotome and an implant is disclosed. The rotational osteotome includes a plurality of steps of different diametrical sizes, a tip, and at least one flute; and every step includes an annular bottom bevel to provide a cutting edge and recessed section. The implant includes a body having a cylindrical head section and a conical section provided with an external thread and a plurality of spiral flutes. The conical section has a downward tapered profile correspondingly aligned with the recessed sections. The cylindrical head section has a straight cylindrical profile matching that of the step having the largest diametrical size. With the above arrangements, an implant hole on a bone can be formed in only one drilling with one single osteotome for fixedly holding the implant therein. Therefore, the time needed for dental and orthopedic surgeries is largely shortened while better osseointegration can be achieved.

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 biological tissue rootage face (30) capable of closely bonding to a biological tissue (H, S) is composed of a biocompatible material and has numerous fingertip-shaped microvilli (41). The microvilli (41) have tip diameters in the order of nanometers. An implant (1) has the biological tissue rootage face (30) on a surface (11, 24) configured to root into a biological tissue (H, S). In a method for forming the biological tissue rootage face (30), a surface of a biocompatible material is subjected to laser nonthermal processing carried out by emitting a laser beam in air, to form numerous fingertip-shaped microvilli (41). The laser beam is a laser beam of an ultrashort pulse laser.

A dental attachment assembly is provided, including an abutment member and a male member. The abutment member may include an outer locating surface portion having at least two axially spaced retention portions having two generally rounded, annular projections. The male member for engagement over the outer locating surface of the abutment member may include an upper end and a continuous, unbroken skirt having a rounded, convex outer surface. The male member may be constructed from a rigid material and have at least two axially spaced, snap engaging formations on the inner surface of the skirt for snap engagement with the respective retention portions of the abutment member.

An anatomical healing abutment is configured to connect to a dental implant. The healing abutment has a body portion which includes at least three reference marks that provide data to orient the connection axis of the abutment with the that of the dental implant so that certain conventional steps, including healing abutment manipulation, multiple scans, and the taking of impressions, can be eliminated, thereby saving time and effort on the part of the practitioner.

A dental implant adapted for implanting within a jaw bone, the implant comprising a horizontally-oriented body having a length extending in the mesial-distal direction of the jaw bone, the body having a threaded cavity dimensioned for receiving a prosthetic abutment, and wherein the cavity comprises an opening that is located wholly within a buccolingual width of the body.

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).
