Preferences of Fixed Orthodontic Appliance Use in Conjunction with Clear Aligner Therapy
Abstract
Purpose: To determine preferences for the use of conventional fixed orthodontic appliances in conjunction with clear aligner therapy (CAT), such as Invisalign, amongst dental providers primarily in the United States of America (U.S.A). Methods: A survey was composed and sent to approximately 2300 orthodontists and 45,600 dentists. The questionnaire focused on gathering information regarding the subjects use of CAT for certain malocclusions, premolar extraction cases, incisor extraction cases, and orthognathic cases. It explores preferences in respect to the use of fixed appliances for either beginning or finishing clear aligner treatment. Analysis of the data was performed to determine providers preferences in using fixed appliances. Data between two groups (orthodontists and non-orthodontists) was compared to look for any statistically significant differences. Results: Orthodontists were more likely than non-orthodontists to use fixed appliances to finish CAT on Class I (p=.0113), premolar extraction (p=.0015), and incisor extraction cases (p=.0011) when using Invisalign, and on Class I (p=.0004) cases when using ClearCorrect. Non-orthodontists were more likely than orthodontists to use fixed appliances to finish Cl III cases (p=.0174) when using in-house lab CAT. Roughly half of the providers (53.4%) believe that midcourse corrections are often or very often necessary. Conclusions: Orthodontists are generally more likely to use fixed appliances to finish CAT, depending on the brand and case type. About half of dentists believe that midcourse corrections are often or very often necessary.
