Summary The purpose of this study was to report on the 7‐year follow‐up of 15 patients who took part in a prospective randomised controlled split‐mouth trial to evaluate the performance and patient satisfaction of 107 direct composite restorations bonded to their worn anterior mandibular dentition. This is the continuation of a study by Poyser et al ., which investigated the performance of the same direct composite restorations on this cohort of patients at 2·5 years. The results of the present study suggest that direct composite restorations bonded to the worn anterior mandibular dentition to have an approximate survival of 85% at the 7‐year follow‐up. Approximately 53% of patients experienced survival of all of their restorations. Pre‐operative circumferential preparation did not influence restoration survival, patient satisfaction or other clinical variables (restoration staining, marginal discolouration, shade match, surface roughness and marginal adaptation). The time taken to initially build‐up the restorations was shown to be statistically significant with a longer procedural time meaning less chance of the restoration being present at 7 years. This treatment modality exhibited no biological complications for the teeth, supporting periodontium or TMJ apparatus. The placement of these restorations provided an improvement in the aesthetics of the teeth, a reduction in the concern over the longevity of the worn lower anterior teeth, and improvements with regard to sensitivity experienced with hot or cold foods or drinks. Marginal breakdown was the most frequently recorded clinical complication. Thus, for the majority of patients, the restorations offered a high degree of patient satisfaction and required an acceptable level of maintenance in the 7‐year follow‐up period.
