Abstract: The present invention is related to the dentistry field. More precisely, the present invention relates to a system for insertion into the root canal for obtaining a root fastening element to support crowns comprising a sleeve of flexible and moldable material, non-adherent to the walls of the root canal, wherein the sleeve comprises a root section and a crown section which are filled with fibers in different arrangements. In addition, the present invention is related to a method for obtaining a fastening element using the system and root fastening element to support crowns.

Abstract: This disclosure provides bioceramic compositions of multiparticulate crystalline multimetallic silicates having silica double tetrahedra structures, such as Strontium-akermanite (Sr2MgSi2O7), Akermanite (Ca2MgSi2O7), Baghdadite (Ca3ZrSi2O9), Hardystonite (Ca2ZnSi2O7), as sources for controlled release of multiple metallic ions, such as Ca2+, Mg2+, Zr4+, Sr2+, Zn2+ for medical and dental use. This disclosure also includes medical and dental uses of the disclosed compositions, for example, in tissue regeneration, including bone tissue.

Abstract: The present invention relates to cements useful in dental applications, and more particularly to dental compositions which may release calcium ions, which may comprise at least one of salicylic acid ester derivative and a calcium source. The present invention further relates to the use of at least one of salicylic acid ester derivative and a calcium source for producing a dental composition, having biological properties and which may release calcium ions for use in dental procedures of intermediate restorations and channel filling.
