Abstract Objective To explore and analyze the effect of special orthodontic retainers in orthodontics and its impact on the quality of life of patients.Methods A total of 60 orthodontic patients admitted to West China Hospital of Stomatology, Sichuan University from January 2018 to January 2020 were selected as the research objects.They were divided into observation group (30 cases) and control group (30cases) according to the order of admission time.The control group used the Hawley retainey method, and the observation group used the improved hot-pressed film transparent crown retainer method.The width of the canine arch and the width of molar arch, living mass, diet, sleep quality, and self-conscious symptoms were compared between the two groups.Results After follow-up, the patients of two groups showed no significant differences in the width of the upper and lower canine arch and molar archwidth (P＞0.05);the molar arch width and Little index of the observation group were lower than those of the control group, the difference was statistically significant (P＜0.05);after treatment, the observation group′s quality of life, quality of sleep, and selfconscious symptoms scores were higher than those of the control group, and the differences were statistically significant(P＜0.05).The satisfaction scores with masticatory function, comfort, aesthetics, and language pronunciation of the observation group was higher than that of the control group, and the differences were statistically significant (P＜0.05).Conclusion The improved heat-pressing film transparent crown retainer has a definite effect in orthodontics and is worthy of optimization.
