Customized 'G-Shell' to guarantee aesthetics during impacted canine aligner treatment

During the orthodontic treatment of impacted canines with aligners, there will be a phase in which patients will have a wide space in the maxilla to host the canine extrusion. In this situation, aesthetics can only be guaranteed if the patient wears aligners containing some coloured resin, although this will not be of any help when they eat. An alternative option could be a customized shell covering the buccal surface of the first premolar (and, if needed, the second premolar) with a thin extension that covers the canine area. The lingual surface of the premolars can be used for sectional wires for extrusion and buccal forces. In this way, patients' aesthetics could be guaranteed at all times, while at the same time new aligners can be planned simply by taking a new scan with the 'G-Shell' in place and blocking the movement on the teeth.
