A reinforcement bar combination for a direct dental bridge, the reinforcement bar combination including: first and second elongate bars, each of the first and second elongate bars contacting a single occlusal preparation formed in a single abutment tooth and each of the first and second elongate bars having an end positioned on a central pad of a third elongate bar to form a reinforcement scaffold. The first elongate bar is a first elongate torque bar that is optionally bent. The second elongate bar is a second elongate torque bar that is optionally bent. The third elongate bar is a proximal bar including a central planar pad bound by a perimeter, a coronal facing surface and an apical facing surface, a first insertion arm extending in a mesial direction from the perimeter of the pad, a second insertion arm extending in a distal direction from the perimeter of the pad; a first vertical sidewall extending in a coronal direction from the coronal oriented surface of the pad; a second vertical sidewall extending in a coronal direction from the coronal oriented surface of the pad. A method of using of the reinforcement bar combination to produce a direct dental bridge is also described.

The present invention relates to a method for manufacturing a zirconia slurry for forming porous surfaces on an abutment and a crown of a ceramic implant, the method including: the zirconia pulverization step (step S10) of putting zirconia powder, carbon powder as a foaming agent, and an organic binder in a ball mill and agitating and pulverizing the zirconia, carbon powder, and organic binder to allow the mixed zirconia powder to have nanoparticles; the carbon powder oxidization step (step S20) of heating the zirconia powder mixed with the carbon powder to a temperature of 1200 to 1800 C. and oxidizing the carbon powder to a concentration of 10 to 40 wt % to allow the porous surfaces to be formed on every particle of the zirconia powder; and the degreasing step (step S30) of putting a dispersing agent and a solvent in the zirconia powder whose particles have the porous surfaces to make a zirconia solution and removing the organic binder from the zirconia powder.

A dental prothesis configured to be placed in a gap between a first adjoining tooth and a second adjoining tooth so as to replace a missing tooth. The prothesis includes two partial abutments configured to sit within the gap between the two adjoining teeth. Secured to each partial abutment is a connector which is also secured to one of the adjoining teeth. Each connector is in a substantially C-shape configuration and adapted to fit along the surface of the associated adjoining tooth. The connectors have a plurality of connecting points that are adapted to fit within one of a plurality of retention grooves ground in the adjoining teeth to affix the connectors to the adjacent teeth with little grinding of the adjacent teeth. A crown is adapted to fit over and about the two partial abutments.

A method is proposed for ascertaining the spatial positions and orientations of at least two implants anchored in a jaw of a patient, said method having the following steps: 1. An adhesive bond aid is produced that bridges the implants and has negative molds of adhesive caps, wherein the negative molds fit on the adhesive caps if these are affixed to the implants, and wherein the negative molds allow a clearance relative to the adhesive caps. 2. The adhesive caps are affixed to the at least two implants in the jaw of the patient. 3. The adhesive bond aid is positioned over the adhesive caps. 4. The clearance between the adhesive caps and the negative molds is filled with adhesive. 5. The adhesive is cured. 6. The adhesive caps are released from the implants. 7. The obtained adhesion key is removed from the patient.

A dental restoration, a method for the production of a dental restoration and a kit. The dental restoration comprises an outer component, in particular a shell, and an inner component, in particular a core. The inner component and the outer component contain composite material. The outer component is mountable or mounted on the inner component. The inner component is designed for attachment onto a tooth preparation, in particular a tooth stump.

Techniques for generating a multi-layered thin film coating for dental applications are disclosed. An example of a dental substrate with an aesthetic coating includes a barrier layer deposited on the dental substrate, a textured layer deposited over the barrier layer, the textured layer comprising a first material with features of a size sufficient to scatter light, and at least one protective layer deposited over the textured layer.

A method of fabricating a dental restoration is provided that includes the initial step of providing a powder of a dental material. An amount of a binder is then selectively deposited onto the powder of the dental material to produce an unfinished layer of the dental material. Multiple layers of the dental material are then produced by continually providing a powder of dental material and selectively depositing an amount of a binder until a three-dimensional unfinished model is produced. The unfinished model is then separated from an amount of unaffected powder, and is sintered to produce a three-dimensional dental restoration having a functionally-graded structure.

A dental abutment core with a prosthetic connection, a pillar and a shoulder located between the prosthetic connection and the pillar. The pillar has anti-rotational elements for preventing a custom body from rotating with respect to the dental abutment core. The pillar has a first portion adjacent to the shoulder, a second portion adjacent to the first portion, and a third portion farthest from the shoulder. A cross section of at least part of the first portion is circular and has an outer diameter which is lower than a cross section dimension of the second portion. The anti-rotational elements are located in the third portion. A method for manufacturing a dental abutment with such dental abutment core is also described.

The present invention relates to a polymerizable composition, which comprises (a) at least one radically polymerizable oligomer, (b) at least one radically polymerizable monomer and (c) at least one initiator for the radical polymerization, characterized in that the radically polymerizable oligomer (a) is selected from the group consisting of aliphatic urethane (meth)acrylate oligomers, epoxy (meth)acrylate oligomers and polyether urethane (meth)acrylate oligomers, and the radically polymerizable monomer (b) is polyfunctional.

The present invention relates to a method for the design and manufacture of a dental component with a surface, wherein a 3D model of the dental component is designed by means of a CAD unit and the dental component is manufactured by a CAM unit on the basis of the 3D model. In order to provide a method which significantly shortens the time required for the design and manufacture of a dental component, so that the length of the dental session at which the patient must be present is shortened, it is inventively proposed that the 3D model is manufactured in at least one first design step, in which a first 3D submodel is designed with at least one first surface section, and a second design step in which a second 3D submodel is designed with at least one second surface section, wherein the first design step is completed before the second design step and the CAM unit begins the manufacture of the first surface section of the dental component based on the first 3D submodel before the design of the second 3D submodel is completed.
