A method of an orthodontic treatment, the method including the steps of a) placing a pearl on a tooth, and b) placing a first splint over the teeth of a jaw, at least a tooth being provided with a pearl according to step a). Also the use of a pearl as a holding element for an orthodontic appliance.

A dental article including a dental article body made of a ceramic material and a coating formed on the surface of said dental article body. The coating includes crystalline nanostructures made of yttria-stabilized zirconia YSZ.sub.1, the crystal habitus of at least a portion of the nanostructures having at least approximately the shape of a regular convex polyhedron.

The invention relates to an intermediate dental abutment (2), intended to be inserted into a dental implant (1), the intermediate abutment (2) comprising: a lower part (20), intended to be inserted into an implant (1); an intermediate part (28), comprising an external connection device (29) for connecting a blanking element (4) of anatomical shape to close off the site of the post-extraction cavity; an upper part (24) comprising a fixing device (304) for fixing a member (9, 100), such as an impression abutment (9) or a prosthetic abutment (100).

The invention relates to a mouthpiece and method for antibacterial treatment of intraoral surfaces. The mouthpiece comprises a body made of light-guiding material, the body comprising facial and lingual outer surfaces and facial and lingual inner surfaces adapted to face facial and lingual surfaces of teeth, respectively. A light source is attached to the body and adapted to deliver light to surfaces of teeth, the light source being positioned on at least one of said outer surfaces and adapted to deliver said light via said inner surfaces to both the facial and lingual surfaces of the teeth, wherein a portion of light is adapted to travel through said body from the facial side to the lingual side, or vice versa.

This invention relates to the field of medical technology, and can be used in dentistry and traumatology, in particular when creating dental implants. Namely, the invention relates to the development and creation of a method for producing a dental implant characterized by high strength, as well as increased ability to activate the process of osteogenesis and osseointegration. The implant obtained by this method is characterized by high biocompatibility, bactericidal properties (reduces pronounced dystrophic and necrotic processes of living tissue), and an increased level of implant surface strength.

An orthodontic mould to be applied to one or more of a patient's teeth, the mould having: at least one cavity configured to be positioned adjacent a respective tooth of the patient, with the at least one cavity to receive a settable material to provide a projection, the projection to be fixed to a respective one of the teeth; and a rod or stint mounted in the mould and extending from the at least one cavity so as to be secured to the projection when the settable material is set.

An apparatus and method for automated dental treatment having a tooth clamp (48, 700) which connects an automated dental drill (10). The tooth clamp (700) has a rigid frame (704A, 704B) with a coupling point (703) for reversibly coupling the tooth clamp (700) to an automated dental drill (10) and a pair of jaws (701A, 701B) for coupling the clamp to a tooth of a user. A first jaw surface has a shape adapted to mate the tooth surface and is fabricated based on surface data or a three-dimensional model of the scanned tooth. The tooth clamp (700) has suction ports (702) and the system (900) has irrigation nozzles (903).

Disclosed herein is a method for forming an anti-microbial layer on an apparatus. Also disclosed is a method for improving the anti-bacterial properties of a titanium device coated with titanium-nitride (TiN). Also disclosed is a medical apparatus comprising an anti-microbial layer prepared by the disclosed methods. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

Disclosed herein are antifungal composites, devices, and methods to reduce or prevent a fungus from growing on the antifungal composite. The antifungal composite and devices thereof may include a biocompatible polymer and a Si.sub.3N.sub.4 powder loaded in at least a portion of the biocompatible polymer. The polymer may be a thermoplastic polymer such as a poly(methyl methacrylate) (PMMA) resin and the Si.sub.3N.sub.4 powder may be present in a concentration of about 1 vol. % to about 30 vol. % in the thermoplastic polymer.

The present invention pertains to a photocurable composition for a 3D printer for producing a transparent orthodontic device. A photocurable composition for a 3D printer can be provided, which has excellent physical properties such as thermal properties, strength, elastic modulus, and tensile elongation, and when used in a patient-customized transparent orthodontic device, the orthodontic device can reduce the pain felt by patients and can enhance orthodontic correction effectiveness due to being closely fitted to the dental structure. Moreover, a 3D-printed transparent orthodontic device can be produced which can be restored to the original shape thereof even when deformed from use.
