Key Points Composite resin placed at an increased vertical dimension acts in a similar manner to a 'Dahl' type appliance. Composite resin offers a viable treatment option in the management of localised anterior tooth wear. There is emerging evidence that composite resin has acceptable clinical performance when used in this way. This approach is most conservative and does not preclude other options in the future. Objectives To examine the clinical performance of resin-based composite restorations placed at an increased vertical dimension when used to manage localised anterior tooth wear. Design A retrospective analysis of cases treated at a single centre. Setting UK Hospital setting in year 2000. Subjects and Methods Two hundred and twenty five restorations placed in 31 subjects were included. Assessment was made following examination of study casts and projected slides. Modified United States Public Health Services criteria were used and data analysed using the software Statistical Programme for Social Sciences (SPSS) . Survival analysis was carried out at two levels, major failure only and all types of failure. Kaplan-Meier survival plots were produced against different variables and modes of failure were also noted. Results Major failure requiring replacement of the restoration was uncommon within the first five years. Minor failure requiring repair or refinishing presented mainly as wear, marginal discolouration or marginal fracture. Median survival was 4 years 9 months when all types of failure were considered. The restorations have good appearance and are well tolerated. Conclusion Placement of resin-based composite restorations at an increased vertical dimension to treat localised anterior tooth wear, has good short to medium term survival. The technique is conservative and relatively easy to maintain.
