Prosthetic treatment of dentinogenesis imperfecta. A case report

Prosthetic reconstruction was made on dentition affected by dentinogenesis imperfecta. The bite was first raised with fixed bite plates, and then with temporary acrylic bridges; finally full gold and veneer crowns were made in the posterior teeth. The crowns were retained on the severely attrited teeth with self-threading parapulpal screws (TMS, Whaledent International, New York, U.S.A.) and amalgam and composite resin (Consise, 3M Company, St Paul, U.S.A.) posts. The teeth seem to have enough strength to withstand the occlusal forces, and the dentine appears hard enough to retain parapulpal screws. The prosthetic construction is still functioning well today, 5 years after starting treatment.
