Introduction: The traditional Hawley retainer has been replaced in many orthodontic clinics by vacuum-formed retainers (VFRs). Aim: To determine differences in compliance and reasons for noncompliance between Hawley and VFRs. Hypothesis: There will be increased compliance with VFRs due to better esthetics, speech, and comfort. Methods: In consecutive months but in a different order, two treatment groups received a set of Hawleys and VFRs following comprehensive treatment. All patients were instructed to wear retainers full time. Patients filled out a standard questionnaire at recall appointments to gauge compliance and preferences between retainer types. Results: There was an increase in preference for and compliance with VFRs within each group. The patients in both groups were reported greater compliance the month they were given VFRs. Following 2 months, all patients showed a preference for VFRs. Reasons for choosing VFRs over Hawleys included esthetics, fit, speech, and comfort. Conclusions: Vacuum-formed retainers when compared directly are preferred over Hawley retainers and lead to higher levels of compliance in the short-term orthodontic retention phase of treatment. Key words: Esthetics; hawleys retainer; Vacuum-formed retainers.
