A dental implant, and a manufacturing method for the same. The dental implant includes a form in which, in order to increase the strength of the connection between a metallic abutment and a dental prosthesis, the abutment and the prosthesis are integrally connected, wherein the prosthesis and the abutment are integrally connected to each other by means of a forming method.

A dental prosthetic assembly includes an additively manufactured semi-flexible reinforcement bar and a polymer and glass outer layer chemically luted to the semi-reinforcement bar outside of the reinforcement bar. The semi-flexible reinforcement bar forms an interior of the dental prosthetic assembly and at least a portion of the polymer and glass outer layer forms teeth of the dental prosthetic assembly. A coupling system of a dental prosthetic assembly includes pins disposed in openings extending into the dental prosthetic assembly and implant abutments configured to be coupled with a mouth of a patient. The implant anchors have horizontal holes configured to receive the pins. The pins secure the dental prosthetic assembly to the implant abutments by moving into the dental prosthetic assembly through the openings and into the holes of the implant abutments.

A polymerizable dental composite material comprising (i) 70 to 85% by weight of an inorganic filler component comprising at least one dental glass and optionally at least one amorphous metal oxide, (ii) 10 to 30% by weight of a mixture of at least two different urethane (meth)acrylates, (iii) 0.01 to 5% by weight of at least one di-, tri-, tetra- or multi-functional monomer not being a urethane (meth)acrylate, (iv) 0.01 to 10% by weight of at least one initiator, of an initiator system as well as optionally of at least one stabilizer and optionally of at least one pigment, wherein the total composition of the composite material amounts to 100% by weight, as well as a polymerized composite material having a flexural strength of greater than or equal to 200 MPa and an elastic modulus of 15 to 20 GPa for producing indirect dentures.

Processes and devices for dental restorations employ molding tools that isolate individual tooth surfaces onto which dental composite material is to be applied and cured into individual cavities to prevent bonding of adjacent teeth. The processes and tools utilize matrix separators between teeth and a molding tool having matrix guide pockets that receive edges of the matrix separators to define the individual cavities.

A multilayer crown includes an outer layer and an inner layer. The outer layer may be formed of a first polymeric material. The inner layer may be formed of a second polymeric material that is different from the first polymeric material. The inner layer may be arranged to contact a tooth so that the inner layer is located between the outer layer and the tooth.

The present invention provides a photocurable composition for use in stereolithography, the photocurable composition including: a (meth)acrylic monomer (X) that is at least one selected from the group consisting of di(meth)acrylic monomers containing, within one molecule, two aromatic rings and two (meth)acryloyloxy groups, and that has a weight average molecular weight of from 400 to 580; a (meth)acrylic monomer (D) that is at least one selected from the group consisting of (meth)acrylic monomers containing, within one molecule, at least one aromatic ring and one (meth)acryloyloxy group, and that has a weight average molecular weight of from 140 to 350; and a photopolymerization initiator.
