Retreatment following in-person clear aligner therapy, direct-to-consumer clear aligner therapy, and conventional fixed orthodontic appliances

This study examined the effect of original orthodontic treatment modality, in particular, in-person clear aligner therapy (CAT), direct-to-consumer clear aligner therapy (DTC CAT), and conventional fixed appliances, on patients seeking orthodontic retreatment. This investigation also studied the effect of original treatment modality on treatment concerns including anterior tooth crowding, anterior tooth spacing, periodontal concerns, and occlusal discrepancies. A survey was sent to 66 U.S. accredited Advanced Education Orthodontic Residency Programs in Oct. 2019. We received 11 fully completed surveys for a 17% response rate for the retreatment analyses. Based on analysis of variance, (α=0.05), the reported proportion of patients seeking orthodontic retreatment following treatment by conventional fixed appliances was significantly higher than that of both in-person and DTC CAT. There were no significant differences between original treatment modality and any treatment concerns. With increased numbers of patients completing treatment with new orthodontic treatment modalities such as DTC CAT, additional investigations will be necessary to fully comprehend the long-term patient satisfaction after orthodontic treatment.
