An implant fixture is disclosed. The implant fixture contains an elongated shaft section, a head section, wherein the head section comprises at least one concave area for bone growth therein, and a protrusion extending from the head section.

A dental implant with a specialized thread arrangement is disclosed. The dental implant includes a cylindrical upper section and a tapered lower section coupled to the cylindrical upper section. A helical thread is located on the exterior surface of the cylindrical upper section and the tapered lower section. A path is defined by the helical thread. The helical thread has a section on the exterior surface of the cylindrical body section and a section on the tapered body section. A cutting tooth is formed on the helical thread below where the thread section on the cylindrical body section transitions into the thread section on the tapered body section. The cutting tooth allows minimal torque to be applied to create stability of the implant by cutting into the dense part of the bone.

An implant formed by two implants: an upper implant and a lower implant, the upper implant being removable. The implant differs from conventional implants in that the body of the implant has a second polished collar corresponding with the beginning of the lower implant. The two implants are connected by a screw located in the lower part of the upper implant of which it forms a part, the screw engaging with the thread of the lower implant. The connection between the two implants is circular, as it must allow anticlockwise rotation when removed.

A bionic fixing apparatus is provided. The bionic fixing apparatus includes a flexible portion having at least one trench. The trench is disposed on the surface of the flexible portion and has a first end and a second end. An interval is disposed between the first end and the second end. The trench is disposed for spreading the stress applied on the bionic fixing apparatus and preventing stress concentration and stress shielding.

The porous three-dimensional structure of the implant is made as a three-dimensional body with open through pores and one-side open pores distributed evenly on the internal surface of open pores and connected to the internal surface. Sizes of pores are randomly distributed in the range of 150-300 μm. A reinforcing element is made from titanium or titanium alloy as a mesh with the protrusions evenly distributed on the outer surface of the mesh, and is located on the surface of the three-dimensional body. The method of manufacture and method of installation of one of the variants of the dental implant with the possibility of press fit in the jaw bone immediately after extraction of the tooth without arrest of bleeding are based on the porous three-dimensional structure claimed as well.

A method of forming an implant to be implanted into living bone is disclosed. The method comprises the act of roughening at least a portion of the implant surface to produce a microscale roughened surface. The method further comprises the act of immersing the microscale roughened surface into a solution containing hydrogen peroxide and a basic solution to produce a nanoscale roughened surface consisting of nanopitting superimposed on the microscale roughened surface. The nanoscale roughened surface has a property that promotes osseointegration.

The present invention provides for a hybrid dental implant having a screw body with at least one external thread, which includes an upper portion with an open ceiling configured to receive one or more bone inducing agents and/or therapeutic agents, a middle portion having a hollow inner channel connected to side openings, and a lower portion with a closed floor. The bone inducing agents and/or therapeutic agents are introduced through the open ceiling into the hollow inner channel into the side openings, which enables the bone tissue ingrowth into the hollow inner channel and bone tissue outgrowth from the hollow inner channel to the surrounding bone. It also provides for a method of installing and using the hybrid dental implant thereof.

A dental implant for securing an abutment to a jawbone, the implant including a tapered body having a longitudinal axis, the body including a coronal end and an apical end, the coronal end including an inclined coronal surface. A first bore receives a base portion of the abutment, the first bore extending downwardly from the coronal surface and parallel to the longitudinal axis of the body. A second bore with a footprint larger than the first bore includes a flange adapted to be abutted by a top portion of the abutment, the diameter of the second bore being off-axis and larger than that of the first bore.

The invention relates to a dental implant having various regions with different degrees of surface roughness.

A dental implant includes an implant body extending along a longitudinal axis between a coronal end and an apical end, the implant body having a core along which a helical threading having at least one thread extends. The dental implant includes at least one section in which the threading has a height which gradually decreases in the direction of the coronal end and in which the core is tapered in the direction of the apical end, the thread including an apical surface facing the apical end of the dental implant, a coronal surface facing the coronal end of the dental implant, and a peripheral lateral surface connecting the apical surface and the coronal surface of the thread. The apical surface of the thread has, in a cross-sectional view along the longitudinal axis, a first profile repeating according to an apical pitch. The coronal surface of the thread has, in a cross-sectional view along the longitudinal axis, a second profile repeating according to a coronal pitch. In one section, the apical pitch is greater than the coronal pitch.
