ABSTRACT
Objective To study the clinical application and safety of orthodontic treatment in oral repair. Methods From August 2014 to September 2017,eighty patients with dentition defect admitted in the department of stomatology of Yanzishan Mine Hospital of Datong Mining Group co,LTD were selected.By using digital random table method,eighty patients were randomly divided into two groups,with 40 cases in each group.The control group was directly treated with oral repair, and the observation group was given orthodontic treatment before oral repair treatment.The clinical efficacy,speech function score and recovery time,chewing efficiency and recovery time,gingival crevicular bleeding index,plaque index and X-ray projection measurement indicators of the two groups were com-pared,and the satisfaction and adverse reactions of the two groups were compared.Results The total effective rate of the observation group was 97.50% (38/40),which was higher than that of the control group [85.00% (32/40)] (χ2 =3.914,P<0.05).After treatment,the scores of language function[(8.49 ± 1.56)points],masticatory efficiency [(83.94 ± 12.66)% ] in the observation group were significantly higher than those in the control group[(7.18 ± 1.45)points, (70.12 ± 13.57)% ] ( t =3.890,5.445, all P <0. 05 ). The recovery time of language function [(17.19 ± 5.41)d],and the recovery time of masticatory efficiency [(20.81 ± 4.87)d] in the observation group were shorter than those of the control group[(24.37 ± 7.02)d,(27.54 ± 6.95)d](t=5.124,5.016,all P<0.05). After treatment,the plaque index (1.14 ± 0.36),gingival sulcus bleeding index(1.96 ± 0.64) of the observation group were lower than those of the control group [(1.51 ± 0.40),(2.73 ± 0.87)] (t =4.348,4.509,all P < 0.05).The SNA angle [(71.24 ± 4.98)°],the SNB angle [(72.85 ± 1.07)°] in the observation group were less than those in the control group[(76.59 ± 5.40)°,(74.13 ± 1.39)°] ( t=4.606,4.615,all P<0.05).In terms of satisfaction,the overall satisfaction rate of the observation group was 95.00% ,which was higher than 80.00% of the control group ( χ2 =4.114, P <0. 05 ). The overall incidence rate of adverse reactions of the observation group (2.50% ) was lower than that of the control group(17.50% ) (χ2 =5.000,P<0.05).Conclusion Orthodontic treatment before dental repair in patients with dentition defect can effectively improve the effect of oral repair,improve the speech function and masticatory efficiency of patients,improve the dentition and maxillofacial malformation,and make the patients more satisfied.And it is safe and reliable,can reduce adverse reactions.
