The Effect of Malocclusion Severity and Treatment Duration on Patient Satisfaction with Clear Aligner Therapy
MetadataShow full item record
AbstractObjective: Determine if a patient’s initial malocclusion and treatment duration influenced satisfaction with clear aligner (Invisalign®) therapy. Methods: Thirty-three orthodontic patients treated with clear aligners responded to a satisfaction questionnaire containing twenty-one questions relating to their satisfaction with treatment, approximately two years after completing treatment. Overjet, overbite, and maxillary and mandibular anterior crowding/spacing were measured to determine the initial severity of their malocclusion. Logistic regression analyses with satisfaction factors as the dependent variable were used to quantify associations between patient satisfaction regarding both the initial severity of malocclusion and treatment duration. Results: Overall, patients were satisfied with aligner treatment. However, no significant associations were observed between patient satisfaction and either the initial severity of the malocclusion or treatment duration. Conclusion: The current study does not find that initial malocclusion or treatment duration significantly affects patient satisfaction. Patient satisfaction with clear aligner therapy is generally very high, and multi-factorial.
