Abstract:
Objective:To study the effects of 3D printing digital positioning guide plate for orthodontic treatment of impacted teeth.Methods:88 patients with single impacted teeth(excluding third molars)with a total of 88 impacted teeth were included and were randomly divided into guide group and conventional group(n=44).Helical nickel-titanium push springs were placed be-tween adjacent teeth on both sides of the impacted teeth to open the gap.CBCT scanning and 3D reconstruction,and digital positio-ning guides were used to assist the positioning.Results:The operation time of the guide group and conventinal group was(26.42±4.94)min and(35.78±9.27)min(P＜0.001),the average bone removal area of the window was(66.03±4.67)mm2 and(69.75±7.22)mm2(P＜0.05),respectively.43 and 41 embedded teeth were successfully erupted in the guide group and the conventinal group,respectively(P＞0.05).The average eruption time of the impacted teeth in the guide group and conentinal group was(176.68±9.89)d and(178.18±10.17)d respectively(P＞0.05).Before treatment,there was no significant difference in the levels of IL-6,IL-1β and TNF-α in saliva between the 2 groups(P＞0.05).After one week of treatment,the levels of saliva IL-6,IL-1β and TNF-α in the guide group were lower than those in the conventinal group(P＜0.05).Conclusion:The use of 3D print-ing digital positioning guide plate for orthodontic treatment of impacted teeth can provide accurate positioning,avoid damage to ad-jacent teeth and surrounding vascular and nerve bundles,reduce the difficulty of operation,shorten operation time,and reduce fen-estration and boneless area,can reduce postoperative inflammatory factor secretion and inhibit periodontal inflammatory response.
