A dental prosthesis is disclosed includes a prosthetic tooth element comprising ceramic and a veneer located on a surface of the prosthetic tooth element, the veneer comprising cured dental composite. The prosthetic tooth element can be fixed to a mount in a patient's mouth using the same dental composite used for the veneer. A method of forming a prosthetic tooth element is disclosed including filling a mould that is formed at least partially from flexible polymeric material with a dental mixture comprising ceramic, and applying pressure to the filled mould to form a prosthetic tooth element comprising ceramic with a roughened surface.

Zirconia dental ceramics exhibiting opalescence and having a grain size in the range of 10 nm to 300 nm, a density of at least 99.5% of theoretical density, a visible light transmittance at or higher than 45% at 560 nm, and a strength of at least 800 MPa.

The invention relates to the field of dentistry and is intended for restoration/reconstruction of teeth decayed/fractured below the gum line using reinforcement technology of composite materials. The indirect atraumatic method for restoration/reconstruction of teeth decayed/fractured below the gum line comprises using a metal mesh-reinforced composite (MMC) dental prosthesis according to M. L. Melikyan, which is made by a laboratory method using gypsum models. The metal mesh-reinforced composite (MMC) dental prosthesis is comprised of a flexible crown-root wire pin and reinforcing crown-root frame assembly made from a mesh and free mesh wires. The walls of the crown part of the dental prosthesis are formed from a composite material. The proposed technology makes it possible to allow for the residual effects of polymerization shrinkage of the composite material during production of the metal mesh-reinforced composite (MMC) dental prosthesis and to ensure the quality of grinding and polishing of the crown part of the prosthesis, and, consequently, to increase the stability and durability of the restoration/reconstruction of the restored tooth.

A method for manufacturing a dental restoration for a patient, where the method includes: obtaining a 3D scan of at least a restoration site of the patient's mouth, where the manufactured dental restoration is adapted for fitting to the restoration site; obtaining a CAD design of the dental restoration; milling the restoration from a material, where the restoration is milled both on an inside surface configured for fitting to the shape of the restoration site of the patient's mouth and on an outside surface, where the milling is according to the obtained CAD design; transferring the milled restoration to a retention means providing a fixed known position of the restoration relative to a post-processing machinery, where the restoration is retained on the inside surface, such that the outside surface of the restoration is approachable/free/accessible; and performing post-processing of the outside surface of the restoration.

An example method for detecting stability of a medical implant is provided. The method includes (a) applying a force to the medical implant with a probe, (b) based on the applied force, determining a response signal associated with a vibration of the medical implant, (c) comparing the determined response signal with a computer model of the medical implant, and (d) based on the comparison, determining an angular stiffness coefficient of the medical implant, wherein the angular stiffness coefficient indicates a stability of the medical implant.

Dental implants including radiopaque markers provided therein or thereon. The implant may also include customizable length characteristics. For example, a kit may include implants with different diameters (e.g., 3 diameters), where all of the implants are of a single (e.g., long) length. The appropriate diameter implant may be selected from the kit by the practitioner, and the long length implant may be cut (e.g., with a dental drill) to the appropriate length needed. The implants include radiopaque markers on or within the implant. For example, three series of markers may be provided on different faces of the implant, so that the three series of markers serve as reference points when scanning, allowing triangulation of the exact position of the implant in relation to the surrounding hard and soft oral tissues.
