An implant abutment according to the present invention is a dental implant abutment with an enhanced shock distribution function, the dental implant abutment comprising: an upper coupling portion that is an upper portion coupled to an artificial tooth; a lower coupling portion that is a lower portion coupled to a fixture, and an exposed portion that is exposed to the outside between the upper coupling portion and the lower coupling portion and has a plurality of flow grooves. By forming a plurality of grooves in the exposed portion of the implant abutment, the exposed portion of the implant abutment performs a shock distribution function as if it shakes elastically and distributes an occlusal force of teeth exerted to the implant, thereby providing a buffering function of relieving an impact on an area where the implant is inserted.

The present invention concerns the preparation of chemically modified derivatives of chitosan with acrylic groups and their use in the field of enamel-dentin adhesives. Chitosan derivatives have physical-chemical features (hydrophilicity, presence of electrical charges on the chain) which allow them to interact with the organic part of the demineralized tooth. At the same time, the acrylic groups incorporated in the polymer chain allow the formation of a covalent bond with the restorative material used in the dental field that is typically composed of acrylic resins. By combining the adhesion to the tooth surface and the bond with the restorative material, the chemically modified chitosan described herein is able to increase the lifespan of the dental restoration and can thus find use in the field of adhesives, in particular enamel-dentin adhesives.

Disclosed are endodontic filling materials and methods. A method for filling a dental root canal may include providing a hydrosetting filling material and inserting the hydrosetting filling material into the dental root canal, the material setting in the root canal to form a biocompatible filling. The hydrosetting filling material comprises a hydrogel former and a filler. The hydrogel former is at least one of a reactive organic hydrogel formers, an inorganic hydrogel formers, and a non-reactive organic hydrogel formers, and the filler is at least one of a self-hardening and a non-hardening filler. Plural filling material precursor compositions that collectively contain hydrogel formers and fillers may be provided.

A dental composition for the desensitization and covering of an area of a human tooth comprising a finger malleable base material made up of a product consisting of either: one or more hydrocarbon-based waxes, possibly with either or both of an organic filler and an inorganic filler, an uncured, uncross linked silicone high consistency rubber base; or a hydrophobic water insoluble solid material that is malleable at 37 C. or lower and safe for a human oral environment. The dental composition also includes a combination of dry, powdered materials dispersed on a tooth-engaging surface of the finger malleable base material. The combination of dry, powdered materials comprises a water-soluble polymeric adhesive and at least one dental tubule blocking agent or hypersensitivity desensitization ingredient.
