Zahnärztliche Zusammensetzungen, Verfahren zur Herstellung von geformten, zahnärztlichen Artikeln via 'photoiniferte Polymerisation' von zahnärztlichen Zusammensetzungen und dadurch erzeugte geformte, zahnärztliche Artikel.

摘要

The present invention provides a novel dental composition and a method of making shaped dental articles therefrom via photoiniferter polymerization. The dental composition comprises acrylic photoiniferter block polymer, a monomer charge comprising free radically polymerizable acrylic monomer, and a filler and optionally includes pigments, sensitizers, medicaments, stabilizers, accelerators, etc. The dental composition is alternately exposed to a source of radiant energy and shaped in a desired manner in order to form a partially cured dental article. The partially cured dental article is then cured by a final exposure to the radiant energy source, providing a final cured article. The resultant reinforced acrylic copolymer system provides a shaped dental article which can be a denture base, a denture liner or a restorative.
