Prosthetic treatment for severe open bite malocclusion and loss of several teeth

This report describes a prosthetic approach that uses fixed partial dentures to establish stable posterior occlusion. Four fixed partial dentures were made of a silver-palladium-copper-gold alloy; the pontics were veneered with a light-curing indirect composite material. They were prepared using a thiouracil metal conditioner and seated with an adhesive luting cement. The clinical follow-up indicated that the prosthetic procedure reported here is applicable for severe anterior and posterior open bite malocclusion.
