摘要:
A method for improving soft tissue attachment which includes the steps of coating a surface of a material, to which surface soft tissue is to be attached, with a coating rich in TiO2 and/or SiO2, and applying the coating where soft tissue attachment is desired. An implant in which a surface or surfaces of the implant intended to be attached to soft tissue are coated with a porous coating rich in TiO2 and/or SiO2, and the use of a porous surface coating rich in TiO2, SiO2, or TiO2 and SiO2, for the manufacture of an implant for soft tissue attachment are also disclosed.
摘要:
A material for medical use in humans and/or animals bearing a biologically active agent, the material being multilayered, as well as a device of this material and a method to produce it. The material includes a core material, where the core material is formed into a body, optionally having the shape of a finished device; two or more layers of coating material of which the first layer has been applied onto the core material and additional layers have been applied onto the coating material of a preceding layer; and where at least one of the layers includes the biologically active agent. A feature of this invention is that the coating material is a biopolymer, a sol-gel produced silica gel or a biologically active molecule.

This invention relates to bioactive sol-gel derived silica fibers, methods for their preparation, an implantable device comprising the fibers and the use of the device for tissue guiding or bone repair.
摘要:
A pharmaceutical preparation, including a glass phase which is bioactive silica containing glass in the form of a paste, suspension or solution mixed in a physiologically suitable liquid or bound to a physiologically suitable vehicle, and which preparation reduces the pulpal irritation or a tooth and/or strengthens the structure of a tooth. Bioactive silica containing glass may be a material which contains only Si-oxide or Si-hydroxide and which allows the formation and movement of Si--OH-groups. Preferably, the preparation also contains calcium and phosphate sources.
摘要:
A bioceramic system for delivery of a bioactive compound, which comprises a combination of bioactive glass, bioactive glass ceramic or bioactive ceramic, hydroxyapatite, optionally one or more other calcium phosphate compound and optionally a matrix, and which may incorporate into the bioceramic system a bioactive compound. The timing of the release of the bioactive compound can be regulated as desired and depends on the conditions of the surrounding, the composition of the bioceramic system and its method preparation.
摘要:
The invention relates to a prepreg comprising a base part, said base part comprising fibers and a matrix, said matrix being at least partially uncured. The prepreg is characterized in that it further comprises a surface part consisting essentially of bioactive filler material, said bioactive filler material being in particle form and at least partially and at most partially embedded in said base part. The invention also relates to a composite obtainable by curing said prepreg. The invention further relates to a mineralizing sheet for treatment of hypersensitive teeth and to the use of said prepreg and composite.
