Intentions and Behaviors to Obtain Invisalign

Abstract

Young adults are often interested in improving the appearance of their teeth. This study determines variables associated with intentions and performance of behaviors associated with obtaining Invisalign, a dental treatment system that uses clear retainers to straighten teeth. We surveyed 525 college students. The theoretical framework was the Theory of Planned Behavior which included questions about attitudes, subjective norms and behavioral control. Other questions included demographics, Invisalign-related questions and dental-related questions. Approximately 18 per cent had used, were evaluated, or were scheduled for an evaluation for Invisalign. Linear regression with the intentions outcome included significance for attitudes (P <0.001), subjective norms (P <0.001), Asian Americans (P <0.001) and look of teeth needs improvement (P <0.05). Logistic regression with the behaviors outcome included significance for subjective norms (OR: 1.10, 95 per cent CI: 1.01–1.16) and visit dentist regularly (OR: 1.87, 95 per cent CI: 1.03–3.42). As subjective norms are factors associated with both intentions and behaviors for obtaining Invisalign, this should be considered when marketing Invisalign to consumers. Also, dentists talking to their regular patients about Invisalign may be useful for persuading these patients to obtain Invisalign.
