The clinical case presented is the demonstration of a multidisciplinary approach to a complex treatment. A precise methodology is important to ensure that the treatment objectives are clear to all the teams. The aim of the treatment is to restore dentofacial harmony to a young, 22-year-old, female patient showing severe attrition of the anterior teeth. The direct effect of this is an ageing of the smile. This type of multidisciplinary treatment, which seems complicated at first, is greatly simplified once time has been spent on the diagnosis and treatment plan: it thereby becomes a succession of clinical stages.
