A dental material having (a) at least one radically polymerizable monomer, (b) at least one radiopaque filler, (c) at least one inorganic filler, (d) at least one composite filler, and (e) at least one initiator for the radical polymerization, wherein the monomer (a) comprises at least one urethane (meth)acrylate, at least one radically polymerizable bisphenol A derivative, optionally at least one polycyclic aliphatic dimethacrylate, optionally at least one monomer which does not fall into one of the groups (a-1) to (a-3) and (a-5), and optionally at least one chain regulator (a-5). The dental material allows the fabrication of esthetically pleasing restorations with only one material.

Provided is a powder material for forming a three-dimensional object, the powder material containing granulated particles containing: a resin; and inorganic particles of which primary particles have a volume average particle diameter of 1 micrometer or less, wherein the granulated particles have a volume average particle diameter of 10 micrometers or greater but 70 micrometers or less and a BET specific surface area of 6 m.sup.2/g or greater but 8 m.sup.2/g or less.

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.
