The invention provides methods of making provisional and long-term dental restorations, particularly dental veneers, implants, crowns and bridges. A shell or restoration form made of polymerizable material having good dimensional shape-stability in its uncured condition is used to make the dental restoration. A polymerizable material is introduced into the cavity of the shell form. The outer shell and injected polymerizable material are polymerized and bond together to form a hardened crown structure. In one embodiment, the restoration can be fabricated indirectly by a dental laboratory. In another version, a dental practitioner can make the restoration chairside for a patient in a dental office.

La présente invention concerne un procédé de fabrication de restaurations dentaires provisoires et à long terme, en particulier des facettes, des implants, des couronnes et des bridges. Une enveloppe ou une forme de restauration fabriquée en matériau polymérisable possédant une bonne stabilité de forme dimensionnelle à l'état non durci est utilisée pour effectuer cette restauration dentaire. Un matériau polymérisable est introduit dans la cavité de l'enveloppe. L'enveloppe extérieure et le matériau polymérisable injecté sont polymérisés et liés ensemble afin de former une structure de couronne durcie. Dans un mode de réalisation, la restauration peut être fabriquée indirectement par un laboratoire dentaire. Dans une autre version, un dentiste peut effectuer cette restauration près du patient dans son cabinet.
