A dental prosthesis to be integrated into a jaw bone cavity of a pre-identified patient. An example of a dental prosthesis includes a first manufactured portion having a surface shaped to substantially dimensionally conform three dimensionally to an undersized shape of the outer three-dimensional surface shape of a root of a tooth to be replaced, and a second manufactured portion shaped to substantially conform to the three-dimensional surface of a crown of the tooth. The outer surface of the root portion can include or be coated with a biocompatible material that is suitable to be integrated into the extraction socket and adopted by existing tissue forming the socket.

Proposed is an adhesive retainer including a body part which is formed of a shape memory alloy material and has a front surface in close contact with and attached to each tooth, wherein the body part includes a curved protrusion part which is formed to protrude toward an interdental space so as to be inserted into the interdental space, and multiple support parts having front surfaces which are in close contact with tooth surfaces of teeth outside the interdental space. A manufacturing method of the adhesive retainer includes a step of acquiring three-dimensional scanning data about a tooth arrangement, a data processing step of generating a first processing line and a second processing line, a laser cutting step of laser cutting a flat plate-shaped base material based on processing line data to form a body-part forming part, and a shape processing step of cutting the body-part forming part.

The present invention provides compositions of bioactive dental materials that form a mineral apatite bond between the dental material and tooth structure for increasing bond strength and longevity. Also disclosed are methods for using said compositions in treating teeth.

A method for making a dental appliance configured to position at least one tooth of a patient includes printing a hardenable liquid resin composition on a major surface of a polymeric material to form a pattern thereon, wherein the hardenable liquid resin composition includes a glass ionomer, a resin modified glass ionomer, and mixtures and combinations thereof. A dental appliance is formed from the polymeric material that includes an arrangement of cavities configured to receive one or more teeth.

The present invention relates to a polymerizable composition, which comprises (a) at least one radically polymerizable compound and (b) at least one initiator for the radical polymerization, wherein the composition furthermore comprises (c) at least one UV absorber and (d) at least one optical brightener and comprises at least one radically polymerizable oligomer and at least one radically polymerizable, polyfunctional monomer as the at least one radically polymerizable compound (a).

The invention relates to a multi-layer, preferably co-extruded, plastic film with improved modulus properties, which is suitable, in particular, for producing three-dimensionally shaped articles.

For improving the quality of use of intraoral orthodontic devices (1) such as dental splints (2) to be worn on teeth as well as for increasing their functionality, such devices (1) are fabricated at least in part, but preferably fully from bio-based materials (5). In particular when using a design featuring a cap layer (4) covering an inner stiff core (3) and including a bio-based material (5), which can be additionally chosen such that it can take-up a significant amount of liquid by swelling, both the micro-deformability of the device (1) can be improved—resulting in increased wearing comfort for the patient and less microplastic contamination for the patient through fossil-based plastic abrasions—and novel functions can be realized, for example releasing substances (9) such as drugs or flavor molecules or bio-based antimicrobial or protective agents from the device (1).
