【 】 Objective To analyze the application effect of invisible orthodontic technique without bracket in oral orthodontics. Methods A total of 209 orthodontic patients admitted to our hospital from January 2020 to December 2023 were selected and divided into control group and observation group by random number table method, 104 cases in control group and 105 cases in observation group. The control group was treated with fixed correction technique, and the observation group was treated with invisible correction technique without bracket. Compare The effective rate of the observation group was slightly lower than that of the control group (P<0.05); The treatment time of observation group was shorter than that of control group (P < 0.05). The oral function score of the observation group was better than that of the control group (P<0.05); The satisfaction of correction in observation group was higher than that in control group (P < 0.05). Conclusion The effect of invisible correction without bracket is ideal, it can shorten the treatment time, improve the oral function, and the satisfaction of patients is higher, which has the value of popularization.
