摘要：
The present invention relates to an organically-modified, organically cross-linked silicic acid (hetero) polycondensate or composite, comprising an organically-modified, organically cross-linked silicic acid (hetero) polycondensate and a filler, for intraoral application, particularly for application when repairing an existing dental replacement in the mouth of a patient or for applying an enamel layer to an anatomically-reduced, milled crown base body already located in the mouth of a patient, wherein said existing dental replacement or said crown base body is comprised of a material having free hydroxy, carboxyl, thio or amino groups, or forming these on its surface following a physical-chemical treatment and/or potentially having active C═C double bonds, comprising the following steps in the mouth of the patient:(a) If necessary, processing of the previously existing dental replacement to remove damaged or no longer necessary elements,(b) Applying a bonding agent to the surface of said potentially processed dental replacement or said crown base body,(c) Overlaying the surface of said potentially processed dental replacement or said crown base body coated with bonding agent with said organically-modified silicic acid (hetero) polycondensate or said composite in a liquid or paste-like form, and(d) Hardening the overlay achieved pursuant to (c) through organic cross-linking by means of light hardening or redox-induced hardening,wherein said bonding agent is or has a compound having at least two identical substituents selected from among hydroxy groups, isocyanate groups, epoxy groups, potentially activated carboxylic acid groups, thiol groups, primary and secondary amino groups of cyclical carbonate groups having a potentially activated C═C double bond.The invention further relates to the use of the specified materials for dental purposes conducted in a laboratory, as well as for purposes beyond the field of dentistry.
