Comparison of The Efficacy and Patients'Experiences of Activator and Forsus in the Treatment of Mandibular Retrognathia
Objective To compare the effect of Activator and Forsus in adolescent patients with mandibular retrognathia in skeletal Class Ⅱ and the experience of patients during the treatment process,so as to provide reference for more targeted selection of clinical orthodontics.Methods In this study,24 patients(10-14 years old)of Activator(group A)and Forsus(group F)were selected to promote mandibular growth,and all of them were aligned with fixed orthodontic technique to end the treatment.The lateral cephalograms were taken before and after treatment.The data of the cephalometrics and the treatment time were compared,and the patients were asked to evaluate the experience of orthodontics through questionnaire survey.Results After treatment,the increase of SNB,the decrease of ANB and the decrease of U1-SN in group A were greater than those in group F,and the differences were statistically significant.The total course of treatment in group A was(20.21±2.96)months,and that in group F was(22.17±2.55)months which is shorter than group F,and the difference was statistically significant(P＜0.05).Patients in group F were better than group A in terms of initial acceptance,wearing time,appearance and pronunciation of the two kinds of appliance,and the difference was statistically significant(P＜0.05).The experience of oral hygiene,appliance damage,mucosal damage and eating in group A was better than that in group F,and the difference was statistically significant(P＜0.05).However,there was no significant difference in the total score of treatment experience between the two groups(P＞0.05).Conclusion Compared with Forsus,Activator leads to more obvious mandibular growth and anterior tooth retraction,and the course of treatment is shorter.In the experience of the two groups of patients,each group has its advantages and disadvantages in the detailed score,but the total score is not significantly different.Clinicians can accurately select the appliance according to the specific situation of the patient.
