Direct-to-consumer orthodontics: Exploring laypeople's perception of orthodontic treatment complexity.

BACKGROUND

The authors aimed to explore the treatment preferences of laypeople regarding direct-to-consumer (DTC) orthodontics and to identify whether case complexity, as perceived by laypeople, is one of the factors influencing interest in DTC orthodontics.

METHODS

An online cross-sectional survey was conducted. Data analysis was performed using logistic regression models.

RESULTS

A total of 1,362 surveys were completed. A significant inverse association was identified between the complexity of an orthodontic case, as measured using the American Board of Orthodontics' discrepancy index (DI) score, and the likelihood of choosing DTC treatment over an orthodontist. Participants were 3.53 times more likely to choose DTC treatment for a mild case (DI score, 0-10) compared with a complex case (DI score, > 20), although the likelihood of choosing DTC treatment for a moderate case (DI score, 11-20) was only 1.79 times higher than for a complex case.

CONCLUSIONS

When laypeople were asked to consider each case as if it were their own dentition, there was a significant inverse association between the complexity of an orthodontic case, as measured using the DI score, and the likelihood of choosing DTC treatment over an orthodontist. Laypeople were seemingly more likely to choose DTC orthodontics for dentitions that did not appear crowded and were well aligned within the arches. Laypeople seemed to have an understanding that there are some limitations to DTC orthodontics.

PRACTICAL IMPLICATIONS

Orthodontists should better understand the factors influencing consumers' decisions to select DTC orthodontics and dental organizations should focus their educational campaigns on these factors.
