OBJECTIVE: To test the null hypothesis that orthodontist characteristics and factors related to retainer choice do not influence the management of the retention phase with regard to frequency and duration of follow-up care provided. MATERIALS AND METHODS: Orthodontists (n = 1000) were randomly selected to participate in an online survey divided into three categories: background, retainer choice, and time management. RESULTS: Of the 1000 selected participants, 894 responded. When deciding the type of retainer to use, the following were considered most frequently: pretreatment malocclusion (91%), patient compliance (87%), patient oral hygiene (84%), and patients' desires (81%). Orthodontists who considered the presence of third molars (P = .03) or "special needs" patients (P = .02) had significantly more follow-up visits than those who did not. When vacuum-formed retainers (VFRs) were prescribed, there were significantly fewer visits (P = .02) compared to when other types of retainers were used. As practitioner experience increased, so did the number of visits (P < .0001). Orthodontists who considered the primary responsibility of retention to fall on the patient had significantly fewer follow-up visits (P < .0001) than those who considered it either a joint or orthodontist-only responsibility. CONCLUSIONS: The null hypothesis was rejected because the number of follow-up visits during the retention phase was affected by practitioner experience, whether VFRs were used, whether the orthodontist considered the presence of third molars or special-needs patients when choosing the type of retainer, and to whom the orthodontist attributed responsibility during the retention phase.
