The invention provides a method of forming dental restorations, particularly dental crowns. The method involves applying a flexible cement composition to a prepared tooth surface. The composition is polymerized so that it substantially hardens. A composite crown- forming material is dispensed into a substantially transparent plastic matrix. The matrix is placed in the mouth of the patient so that the composite material is molded over the tooth surface. Then, the material is irradiated with curing light, through the matrix, so that it hardens to form a dental crown. The crown has good mechanical strength and is resistant to fracturing and breaking.
