Anterior crossbites are often treated interceptively to reduce the risk of enamel wear, periodontal loss of attachment or mandibular displacement. Although various techniques have been described, treatment usually entails the use of a removable or fixed appliance.1 This Trick of the Trade describes an alternative to standard methods for treatment, which involves the chairside placement of lingually bevelled composite resin turbos on the mandibular teeth, thereby nudging the maxillary incisor labially and the mandibular incisor lingually (Figures 13).2,3,4,5,6

The mandibular incisor opposing the maxillary incisor in anterior crossbite is prepared with self-etch primer.

These ‘functional turbos’ are well tolerated, do not rely on patient compliance and provide cost savings compared with removable and fixed appliances (Table 1). However, this technique must only be employed when the patient can achieve edge-to-edge incisor contact in centric relationship, with a positive overbite to provide stability of correction.
