The invention relates to a method for manufacturing a colored blank, which contains zirconium dioxide and is intended for the manufacture of a dental restoration, whereby raw materials in powder form, at least some of which contain one coloring substance each, are mixed with, zirconium dioxide as the main ingredient, the resulting mixture is pressed and subsequently subjected to at least one thermal treatment. To generate the desired fluorescence, it is intended that in the raw materials in powder form one uses as coloring substances at least terbium, erbium, cobalt, as well as one substance that generates a fluorescence effect in the dental restoration, however not iron, aside from naturally occurring impurities.

The present disclosure provides a composite material, a method of making and using the composite material and dental products made by hardening the composite material. The composite material includes a polymerizable component, ceramic fibers and nanoclusters. Each of the ceramic fibers of the composite material has a length and where the length of fifty percent of the ceramic fibers, based on a total number of the ceramic fibers, is at least 50 micrometers and the length of ninety percent of the ceramic fibers, based on the total number of the ceramic fibers, is no greater than 500 micrometers. The composite material can also include discrete non-fumed metal oxide nanoparticles. The composite material can be hardened to become any one of a dental restorative, a dental adhesive, a dental mill blank, a dental cement, a dental prostheses, an orthodontic device, an orthodontic adhesive, a dental casting material or a dental coating.

Provided is an implantable composite which includes a plurality of resorbable ceramic particles with or without a biodegradable polymer. The resorbable ceramic particles can be granules including carbonated hydroxyapatite and tricalcium phosphate in a ratio of 5:95 to 70:30. Some resorbable ceramic particles are granules, which include carbonated hydroxyapatite and tricalcium phosphate in a ratio of 5:95 to 70:30. The resorbable ceramic particles have a particle size from about 0.4 to about 3.5 mm. The implantable composite is configured to fit at or near a bone defect as an autograft extender to promote bone growth. Methods of using the implantable composite are also provided.

A dental implant assembly comprising an elongated inner body substantially resembling a tooth root (1-1) and an outer member for securing to a bone of a patient (1-2) having a heterogeneous porous structure adapted to provide bone growth, the inner body and the outer fixation member being formed in one piece, the fastening element being movable between a stored passive position and an extended active position (1-2).

Provided is a dental pretreatment material for dental tissue regeneration by use of dental pulp stem cells, particularly a dental pretreatment material effectively enabling dental tissue regeneration even by use of dental pulp stem cells of middle-aged or older individuals. The dental pretreatment material is characterized by comprising a serine protease, specifically trypsin. The dental pretreatment material comprising trypsin is used as an injection into a root canal before a root canal filling material comprising dental pulp stem cells and an extracellular matrix is inserted into the root canal as an attempt to regenerate a dental pulp and a dentin. The root canal filling material includes an ALK5 inhibitor, a CCR3 antagonist, or a CCL11 neutralizing antibody.

In a functionalization method for use in dentistry, and a method for same, the application device includes a support for receiving a partially processed shaped dental part for producing a dental restoration, and a dispensing device for the at least partial infiltration of a functionalization material onto the surface of the shaped dental part.

Disclosed is a resin modified dental luting cement composition having a polymerizable resin component, a polyacidic polymer component, a filler component, a redox initiator system, and water.
