Abstract：Objective To compare the application effect of stainless steel ligature wire and elastic ligature ring archwire in oral orthodontics.Methods From January 2014 to January 2019, 124 patients who received orthodontic treatment in our hospital were selected as the study objects.According to the coin tossing method, they were divided into the control group (n=62) and the observation group (n=62).Patients in the control group received elastic ligation and archwire fixation, and the patients in the observation group received stainless steel ligation.The treatment effect after 6 months of treatment, the time of orthodontic ligation and dismantling during orthodontic treatment, oral microbial environment between the two groups were compared.Results The total effective rate (96.77%) in the observation group was higher than that in the control group (77.42%), and the difference was statistically significant (P＜0.05).In the observation group, the orthodontic ligation time and removal time were longer than those in the control group, the differences were statistically significant (P＜0.05).The total detection rate of oral microbes in the observation group (9.68%) was lower than that in the control group (32.26%), and the difference was statistically significant (P＜0.05).Conclusion Compared with the elastic ligation circle archwire treatment during the oral orthodontic treatment, the stainless steel ligation wire treatment can obtain better correction effect and reduce the bacteria in the oral cavity although the ligation time and the removal time are longer.
