Of the 4 main types of amelogenesis imperfecta, hypoplastic (type 1) is the most prevalent, characterized by a quantitative alteration in enamel. The pitting or reduced thickness of the enamel results in generalized hypersensitivity, increased susceptibility to caries and infection, attrition, and a loss in vertical dimension of occlusion. Prosthodontic management of these patients can be challenging not only functionally and restoratively, but also from an emotional and psychosocial standpoint. This clinical report describes the prosthodontic management and rehabilitation of two young adult siblings with hypoplastic (type 1) amelogenesis imperfecta.
