[Restorative and reconstructive treatment of amelogenesis imperfecta after 18 years - a published case comes of age].

The diagnosis and treatment of amelogenesis imperfecta (AI) represents a considerable rehabilitative challenge. Three critical aspects must be emphasised in particular: 1. as a congenital dental dysplasia, AI is a congenital defect, is covered by federal disability insurance and requires early definitive treatment before the age of twenty; 2. treatment is complex, interdisciplinary and usually invasive; and 3. restorations must be fixed on structurally compromised tooth structure.
