A young patient with dentinogenesis imperfecta and a dentition severely compromised by discolorations, abrasion, and breakage of enamel on several teeth was prosthodontically treated with CAD/CAM-manufactured all-ceramic restorations. To reduce treatment risk, preparations were limited paragingivally. Maxillary anterior teeth and premolars were restored with adhesively luted ceramic crowns. All other teeth were treated with zirconia-based restorations luted with a self-etching resin-based material. Considering the deficient pretreatment situation, the use of tooth-colored restoration and luting materials yielded a satisfying functional and good esthetic result. The patient is highly satisfied, even though 3 minor chippings occurred shortly after the completion of treatment. (Quintessence Int 2009;40:19–27)
