Abstract
The invention relates to a material that is used primarily for medical, long-term in vivo purposes, e.g. as a filling material in dentistry. The aim of the invention is to create a material primarily for medical, long-term in vivo use which does not have the disadvantages of materials used in prior art, does not release active substances, and endures after the material has been removed or when the shape thereof is modified. The aim is achieved by the fact that the material is made of polymers and filling agents which are embodied as polymer-coated, chemically modified particles that carry hydroxyl groups and are surrounded by a matrix of another polymer. The coating polymer develops an antimicrobial effect.
