Objective To analyze the effect of microscrew implant anchorage on gingival index and periapical tissues in orthodontic patients.Methods A total of 100 orthodontic patients were randomly divided into a control group(50 cases)and a study group(50 cases).The control group was treated with non-implant anchorage,while the study group was treated with microscrew implant anchorage.The clinical efficacy,gingival index[plaque index(PLI),gingival index(GI)and sulcus bleeding index(SBI),and periapical tissue damage were compared between the two groups.Results The total effective rate was 96.0%in the study group,which was significantly higher than 82.0%in the control group(P<0.05).Compared with before treatment,PLI,GI and SBI in both groups after treatment were significantly decreased(P<0.05).The study group had PLI of(1.28±0.25)points,GI of(1.06±0.11)points and SBI of(1.15±0.14)points after treatment,which were significantly lower than(1.87±0.34),(1.43±0.14)and(1.68±0.15)points of the control group(P<0.05).The rate of periapical tissues damage in the study group was 24.0%,which was significantly higher than 8.0%in the control group(P<0.05).Conclusion Microscrew implant anchorage in the treatment of orthodontic patients can achieve significant efficacy and significantly improve the gingival condition,but it will affect and damage the periapical tissue to a certain extent.Therefore,in the actual clinical treatment,relevant norms should be strictly followed to carry out various operations to reduce operational errors.
