A transfer article includes an acrylate layer releasable from a release layer including a metal layer, a metal oxide layer, or a doped semiconductor layer at a release value of from 2 to 50 grams/inch (0.8 to 20 g/cm). A functional layer overlies the acrylate layer, wherein the functional layer includes at least one layer of a functional material selected to provide at least one of a therapeutic, aesthetic or cosmetic benefit on a dental appliance in a mouth of a patient, and wherein the transfer article has a thickness of less than 3 micrometers. A pattern of a transfer material is on a major surface of the functional layer, wherein the transfer material includes an adhesion modifying material chosen from release materials and adhesives.

A dental blank, having an upper surface and a lower surface, constructed of a flesh-coloured material and a tooth-coloured material. The flesh-coloured material and the tooth-coloured material are bonded together. The interface between the materials with elevations and depressions formed in or at the interface extends through an optionally curved plane, which plane is parallel to or oblique to at least part of the surfaces of the blank.

The present invention relates to a dental blank, in particular a parallelepipedal block, having an upper surface and a lower surface, which is composed of a flesh-coloured material and a tooth-coloured material. The flesh-coloured material and the tooth-coloured material are bonded together. The interface between the materials with elevations and depressions formed in or at the interface extends through an optionally curved plane, which plane is parallel to or oblique to at least a portion of the surfaces of the blank.

A bactericidal insert for introduction into a canal in a tooth during a root canal procedure is provided, along with a method of producing the insert and a method of using the insert in a root canal procedure. The insert is in the form of a carrier having a plurality of pores or interstices. The carrier had been impregnated with a liquid photosensitive dye so that the dye entered the pores or interstices and then the carrier with the liquid photosensitive dye forms a dye-impregnated carrier. The dye-impregnated carrier is configured and adapted for insertion within the canal of the tooth. The carrier, if dried, is adapted to receive a wetting agent to dissolve the dye therein to produce a liquefied dye, which is activatable to produce singlet oxygen within the canal when it is irradiated by light from outside of the tooth.

A composite, three-dimensionally stable facing material for adding aesthetic features to a denture base. The composite may be a flexible, flat strip of material capable of being molded to gingival surfaces of the denture base and retained on the denture base. The strip is capable of being trimmed and then cured to a hardened state. Fibers and/or other characterization may be added for increasing realism of the denture gingival surfaces.

The present invention is related to a dental implant comprising at least a lower part and at least an upper part; wherein said lower part of the dental im-plant, which is adapted to be connected to the jawbone of a patient, is made of an at least first material; wherein said upper part of the dental implant, which is adapted to be connected to the lower part of the dental implant, is made of an at least second material; and wherein the upper surface of the upper part of the dental implant is adapted to be aligned with the upper surface of the jawbone of a patient; wherein said at least first material is different from said at least second material; wherein the at least second material of the upper part of the implant is made of a ceramic material, and wherein said ceramic material comprises zirco-nium dioxide comprising at least one coloring additive. The present invention is further related to a dental restoration system com-prising at least such an inventive dental implant and at least an abutment, wherein the abutment is adapted to be connected to the dental implant, and wherein the abutment is made of at least a third material; wherein the abutment is made of a ceramic material, and wherein said ceramic material comprises zirconium dioxide comprising at least one coloring additive.

Provided in this disclosure is a crown for a damaged tooth that is manufactured via metal injection molding and features an opening into which can be applied flowable dual-cure tooth colored material.
