Transparent aligners: expertise on the part of general dentists

Lara Figini


Orthodontic therapy using transparent aligners (CAT) is gaining more and more popularity as it is preferred to fixed orthodontic treatment by both professionals and patients due to its advantages in terms of comfort, aesthetics, easier oral hygiene, greater maintenance of dental and periodontal health and reduced chair time required. From being able to treat only simple cases, CAT has evolved to be able to manage a wide range of different malocclusions and thanks to particular additional approaches and instruments (for example, miniscrews and corticotomy), with CAT we are currently able capable of treating multidisciplinary and complex patients, such as pre-prosthetic and orthognathic patients.

However, the tooth movement expected from CAT treatment may not be fully achieved, with varying degrees of predictability for different types of tooth movements. This requires orthodontists to have high-level skills and knowledge of advanced CAT techniques.

Literature data report that orthodontists with different levels of orthodontic training differ in their experience and ability in managing patients with clear aligners and that there are significant differences in the clinical applications of CAT between experienced orthodontists and general dentists. It has been found that general dentists received limited training in orthodontic diagnosis and treatment during dental school, and that practitioners with advanced aligner training are better able to eliminate potential risks. Therefore, systematic education on CAT is crucial for professionals. However, to the best of our knowledge, there is no systematic orthodontic curriculum on CAT.

Materials and methods

In a multicenter study, published in the International Dental Journal, the authors determined the knowledge of professionals and offer ideas for future personalized courses on the subject of transparent aligners. The study authors distributed an online questionnaire that covered basic information, the predictability of tooth movements through aligners, and the knowledge about aligners required by professionals. The average CAT tooth movement predictability was derived from the responses of four senior experienced orthodontists to provide a standard reference. The authors performed descriptive statistics, one-way analysis of variance (ANOVA), Student's t test, and multivariable logistic regression analysis with significance set at P < .05.

Results

A total of 190 professionals participated in the study. Participants overestimated the predictability of complex orthodontic cases with difficult-to-achieve tooth movements (e.g., molar mesialization; P < .0001). For the management strategy for the resolution of the most problematic and complex cases and extractive cases, a higher knowledge of the CAT and a high level of preparation on the subject are required. The type of practice, the number of CAT cases completed and the number of those submitted, years of practice, educational background and time using CAT were the factors that influenced questions regarding the predictability of tooth movement using aligners and the knowledge required thereof.

Conclusions

From the data of this study, which must be confirmed in other similar works, it can be concluded that the predictability of tooth movement which is difficult to obtain through therapy with transparent aligners is often overestimated by professionals with limited clinical experience.
