The present invention provides a composition for optical three-dimensional modeling that offers desirable shape accuracy in optical three-dimensional modeling, and that provides desirable transparency and mechanical characteristics upon being cured. The present invention relates to a composition for optical three-dimensional modeling comprising a polymerizable monomer (a), an ultraviolet-absorbing inorganic particle (b), and a photopolymerization initiator (c).

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.

Embodiments described herein are related to pellets that are placed within an extraction site that is in need of bone augmentation and preservation. The pellets are typically cylindrical in shape and comprise a material and a polymer coating. The goal of the pellets are to encourage sufficient new bone growth that jaw bone deterioration is prevented. The pellets create, arrange, and assemble an ideal growth environment for new bone growth to rapidly grow and preserve the original contours of an individual's jaw bone.

A natural and sustainable material is derived from the nut of the tagua palm tree that may be fashioned into devices for humans and animals. A pulverized and reconstituted material is disclosed herein that is also treated with a low temperature atmospheric plasma treatment. In an embodiment, a biocompatible carrier gas is ionized to form a biocompatible atmospheric plasma stream. Material, such as nano-scale powdered hydroxyapatite, is introduced into the plasma stream, which is then applied to the natural nut material.

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.
