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.

A method for manufacturing an implant including the steps of providing an implant element, the implant element made of a non-metallic material, depositing a thin layer of titanium-based material directly over an outer surface of the implant element, and forming a titanium-based structural body in direct contact with the thin layer by three-dimensional (3D) printing, the structural body being thicker than the thin layer of titanium-based material.

A process for providing a topography to the surface of a dental implant, the surface being made of a ceramic material having yttria-stabilized zirconia, the process including: providing a macroscopic roughness to the surface of the dental implant by a mechanical process and/or injection molding technique; and etching at least a part of the roughened surface, wherein etching is carried out using an etching solution having hydrofluoric acid at a temperature of 70 C. at least, such that discrete grains or agglomerates of grains are removed from the yttria-stabilized zirconia, thereby forming recesses and cavities in the roughened surface is disclosed.

Method for manufacturing an abutment (1) made of titanium or of titanium alloy for receiving a dental prosthesis on a dental implant, extending along a longitudinal direction (I-I) between a proximal end (1a) and a distal end (1b), comprising: a proximal section (4) configured to be received in or on a dental implant, a distal section (5) configured to receive and support a dental prosthesis, said distal section (5) having a receiving surface (6) intended to receive said dental prosthesis by bonding.
Said receiving surface (6) is at least partially textured by laser.

A dental implant made of a ceramic material including an implant surface having at least partially a contact angle of less than 20, the implant surface being at least partially covered by a protective layer. The protective layer includes a dextran having a molecular weight of more than 15,000 Da.

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.

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.

There is described an implant comprising: (a) a bone engaging portion positioned at the distal end of the implant, said bone engaging portion comprising: a longitudinally extending distal portion; and an adjoining region positioned at the proximal end of the longitudinally extending distal portion; (b) a transmucosal portion positioned at the proximal end of the adjoining region; and (c) an abutment portion positioned at the proximal end of the transmucosal portion, wherein the exterior surface of the longitudinally extending distal portion comprises a conformal microscale cell structure and optionally, a non-biological coating; wherein the exterior surface of the abutment portion is polished, suitably, to a mirrored or super mirrored finish and/or wherein the exterior surface of the abutment portion has an R.sub.a of between about 1 and about 3 um; wherein the exterior surface of the adjoining region comprises a roughened surface, suitably with an R.sub.a of between about 5 and about 30 um; and wherein the exterior surface of the transmucosal portion comprises a plurality of micro holes.

A dental post made from a zirconia compound, wherein said zirconia compound is at least one of a pure zirconia puck, a zirconia stabilized with yttria (yttrium oxide) compound, a cubic zirconia compound, a Partially Stabilized Zirconia (PSZ) compound, a Tetragonal Zirconia Polycrystal (TZP) compound and a Zirconium based bulk metallic glass (BMG).

A dental implant includes an anchoring region (12) for anchoring in a bone, which preferably includes a thread (14) for screwing in the bone, and a fastening region (22) for attaching a supra-construction, wherein an abutment region (16) adjoins the anchoring region (12), the abutment region (16) having a guide structure with a plurality of outwardly projecting ridges (18) provided thereon, and preferably, grooves (20) being formed between the ridges (20). The guide structure of the anchoring region (12) allows a better osseointegration and counteracts peri-implant bone loss.
