Abstract:
The diacrylate or dimethacrylate cement for bones contains particles which are resorbable by the bones, of apatite and/or bioceramic and/or bioglass. The tridimensional network of the organic matrix as well as the resorption of the charge particles contribute to improving the physical solidity and the biological compatibility with the bone tissue.
Abstract:
The present invention generally relates to the use of pre-formed bodies of Chemically Bonded Ceramics (CBCs) biomaterial for implantation purposes wherein the bodies are prepared ex vivoallowing process parameters to be optimized for desired long term properties of theresulting CBC biomaterial. More particularly, the pre-formed CBC material bodies of the present inven- tion are sintered. The pre-formed body of CBC material is machined to the desired geometry and then implanted using a CBC cementation pastefor fix- ation of the body to tissue. The invention also relates to a method of prepar- ing pre-formed bodies of CBC biomaterial for implantation purposes, meth- ods of preparing an implant thereof having desired geometry, and a method of implantation of the implant, as well as a kit for use in the method of im- plantation.

Abstract:
The present invention discloses a root canal dental paste that includes a first portion made from at least one antibiotic compound and partially set calcium based cement which forms a matrix to at least partially encapsulate the antibiotic compound. The first portion is then ground and combined with a second portion being a non-setting material and an antibiotic to form a paste.
Abstract:
Material is deposited onto a surface, such as a tooth or a bone, to repair or restore the surface. The material is delivered in powdered form and melted by application of a laser. The molten material is entrained in a high velocity fluid stream, typically a gas such as air, and directed to the surface to be treated. The molten material solidifies. The materials include hydroxyapatite, alumina and silicon dioxide.
