The invention provides medical devices comprising high-strength alloys which degrade over time in the body of a human or animal, at controlled degradation rates, without generating emboli and which have enhanced degradation due to the presence of a halogen component. In one embodiment the alloy is formed into a bone fixation device such as an anchor, screw, plate, support or rod. In another embodiment the alloy is formed into a tissue fastening device such as staple. In yet another embodiment, the alloy is formed into a dental implant or a stent.

Pure compressed diamond (PCD), grown in a laboratory, is laser-shaped into dental implants with high tensile strength, high compressive strength, high thermal conductivity, and which are harder than any other substance on earth. PCD is harder than ceramic zirconia and harder than titanium. Because PCD is pure carbon, it is also 100% compatible with carbon-based living tissue. Unlike titanium, it does not provoke an immune response. PCD implants readily integrate into human jawbone. This drastically reduces post-surgery bone loss.

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 implant including a core; at least one screw thread; a first and second region; a central axis; the surface of the core defining an angle with the central axis in the first region and with the central axis in the second region; and the surface of the screw thread defining an angle with the central axis in the first region and with the central axis in the second region. The diameter of the core decreases at a rate in the first region towards the apical end such that the core defining angle is greater than the screw thread defining angle, and the diameter of the core decreases at a rate in the second region towards the apical end such that the core defining angle is the same as the screw thread defining angle. Furthermore, an implant including at least one helical chamber including a depth and length.

Smart dental implant systems and methods for ambulatory dental care are provided. In some embodiments, the disclosed subject matter includes a crown, adapted to mimic a patient's anatomy and location of the smart dental implant system. The crown can include piezoelectric nanoparticles, disposed on a surface of the crown and adapted to generate electricity from a patient's oral motion. In some embodiments, the disclosed subject matter includes an abutment, coupled to the crown. The abutment can include an energy harvesting circuit, operationally coupled to the piezoelectric nanoparticles and adapted to harvest the electricity, and a micro LED array, operationally coupled to the energy harvesting circuit and adapted to photobiomodulate surrounding peri-implant soft tissue.

A process for providing a sterilized dental article, at least a portion of the surface of which exhibiting a contact angle of less than 45°. The process includes the subsequent steps of a) providing a dental article and b) subjecting the initial dental article to a hydrogen peroxide plasma treatment. It is characterized in that the hydrogen peroxide plasma sterilization treatment of step b) is carried out in the presence of a carbon-containing compound, which during treatment is converted to form a carboxylic group attached to the surface of the dental article.

The present invention relates to the field of dental implants, and more specifically to optimization of the macrogeometry of the implant to improve osseointegration. To achieve this improvement, the dental implant (1) contains cylindrical recesses (2) extending from the tip of the thread (6) towards the body of the implant (4), enabling improved blood irrigation, less insertion torque without losing primary stability, and creating osseointegration chambers.

A single tooth implant for a fixed dental prosthesis includes a substantially cylindrical main part which can be inserted into a bore in a jaw bone; an abutment which can be inserted into an annular recess in the main part, the abutment having a bore for receiving a retaining screw and a securing head for the dental prosthesis; and a retaining screw which can be inserted into the blind hole of the main part and traverses the abutment; and at least one annular gap between the abutment and the main part, in which gap a damping element is arranged.

Dental implant (1) for anchoring of a dental prosthesis, wherein the dental implant (1) comprises a core (10) and an external thread (3) surrounding the core (10), wherein the dental implant (1) has an apical end (11) and a cervical end (12) to be screwed by means of the external thread (3) with the apical end (11) first into a recess formed in a jaw bone and to anchor the dental prosthesis at the cervical end (12), wherein the dental implant (1) consists of material which comprises or consists of a metal or a metal alloy, wherein the core (10) has a bulge (A) in the middle area (4) in any cross-section passing through the entire length of the longitudinal axis (L) of the dental implant.

A method for formation of monolithic nanostructures on an implantable device includes: a. depositing a metal film to a surface of the implantable device; b. heating the metal film for a period of time, such that the metal film transforms into multiple discrete nanoparticles, the multiple nanoparticles thereby forming an etch mask on the surface of the implantable device; c. etching the implantable device such that the surface of the implantable device is etched through the etch mask, thereby forming monolithic nanostructures in the surface of the implantable device; and d. (optionally) removing the etch mask, such as by immersion in an aqua regia solution.
