Abstract:
Objective:To explore the application value of cone-beam computed tomography(CBCT)measurement in morphological change of alveolar bone of patients with malocclusion of osseous class Ⅲ after orthodontic treatment.Methods:A total of 50 patients with malocclusion of osseous class Ⅲ after received orthodontic treatment in Wuxi Stomatology Hospital from January 2020 to December 20203 were selected,and they were included in the treatment group,and 50 patients with same condition who did not receive orthodontic treatment in the same period were included in the control group.The height,width and density of alveolar bone of two groups,as well as the bone density surrounding the tooth root,the tooth inclination,the movement distance of tooth,and the CBCT images between before and after treatment,were compared.Results:The heights of long to medium(5.89±0.25)mm,near to medium(5.48±0.11)mm,cheek side(6.37±0.31)mm and tongue side(6.12±0.28)mm of treatment group were all higher than those[(5.23±0.12)mm,(5.11±0.08)mm,(6.01±0.17)mm and(5.79±0.15)mm]of control group,and the differences of them between two groups were significant(t=16.829,19.235,7.200,7.346,P<0.05),respectively.The widths of alveolar bones of tooth root and nasal base of treatment group were all higher than those of control group,and the differences of them between two groups were significant(t=23.566,26.785,P<0.05),respectively.The alveolar bone density and the density surrounding tooth root of treatment group were all higher than those of control group,and the differences of them between two groups were significant(t=6.470,6.042,P<0.05),respectively.The inclinations of upper and lower incisors of treatment group were all higher than those of control group,and the differences of them between two groups were significant(t=3.710,160.815,P<0.05),respectively.The horizontal movement,vertical movement,internal and external movement,and rotational distance of the teeth of treatment group were all larger than those of control group,and the differences of them were significant(t=62.757,115.000,75.000,5.728,P<0.05),respectively.Conclusion:CBCT measurement is of great significance and function during orthodontic treatment,which can realize careful observation and accurate quantitative analysis of alveolar bone morphology changes.
