Introduction . The purpose of this study was to examine patients' perception of the Carriere Distalizer appliance, a fixed functional appliance used to treat Class II malocclusions, via questionnaire. The questionnaire concentrated on a patients' initial experience with the appliance as well as after a time of wear, the amount of time required to become accustomed to the appliance, how many patients experienced certain side effects and the degree to which subjects were effected, if and the extent to which the appliance interfered with daily life and activities, as well as the patient's overall assessment of the appliance. A supplementary goal of this study was to compare the results to the results of a similar questionnaire used to assess patients' experience with another Class II functional appliance, the Forsus Fatigue Resistant Device. Methods . The questionnaire was administered to 42 patients treated with the Carriere Distalizer appliance in both the university and private practice settings and compared to the results of a similar survey administered to 74 patients treated with the Forsus FRD appliance. Results . The results of the questionnaire demonstrated that 97.6% of subjects treated with the Carriere Distalizer had an overall positive or neutral experience. This was significantly greater than that found for the Forsus group. The Carriere group agreed more strongly that they had received adequate home care instructions and that their appliance did not appear overwhelming compared to the Forsus group. 92.9% felt that wearing elastic rubber bands was easy, and the majority of subjects wore their rubber bands as instructed by their doctor. Both groups felt they had received an adequate description of their appliance, delivery and removal of the appliance was quick and easy, the appliance was noticeable to some extent, facial appearance improved with use of the appliance, and the majority became accommodated to the appliance within 2 weeks with a maximum of one month. Generally, associated discomfort and effects on daily life and activities were less for the Carriere group than for the Forsus group. Side effects decreased over time for both groups, often more so for the Carriere group. The major side effects experienced by the Carriere group were difficulty eating and sore teeth, and these improved significantly over time. Soreness from the appliance rubbing on the cheek or lip was the most detrimental side effect experienced by the majority of the Forsus group which worsened over time for a large number of subjects; this side effect was significantly less for the Carriere group. Significantly less breakage was also found for the Carriere appliance compared to the Forsus appliance. Conclusions . For the two populations surveyed, the Carriere Distalizer appears to be more comfortable, offer a more positive overall experience, and has fewer negative side effects compared to the Forsus Fatigue Resistant Device. The results of this study are important because this information can be used to educate patients, as well as potentially reduce anxiety and motivate patients when treatment with the Carriere Distalizer appliance is initiated. A comparison of how orthodontic appliances fair with patients can also be of benefit to the clinician when faced with choosing an appliance in order to optimize patients' satisfaction.
