Observation of the effects of invisible orthodontic treatment and traditional fixed orthodontic on alveolar bone remodeling in severe periodontitis orthodontic patients
Aim To investigate the effects of invisible orthodontic treatment and traditional fixed orthodontic treatment on alveolar bone remodeling in patients with severe periodontitis.Methods 134 periodontitis orthodontic patients were randomly di-vided into a traditional group and an invisible group,respectively.The traditional group was treated with traditional fixed orthodontic appliances,while the invisible group was treated with non-bracket invisible orthodontic appliances.The periodontal health indicators,lip inclination,changes in alveolar bone height and density,cosmetic effect scores,and incidence of complications between two groups were compared.Results The GI,SPD,and GBI of both groups before and after orthodontic treatment decreased compared with that before periodontal treatment(P＜0.05).After 12 months of orthodontic treatment,the GI,SPD,and GBI of the traditional group in-creased compared with that before orthodontic treatment(P＜0.05),and the invisible group was lower than the traditional group after 12 months of orthodontic treatment(P＜0.05);After 12 months of orthodontic treatment,the inclination of the upper and lower jaw lips in both groups decreased compared with that before orthodontic treatment,and the invisible group was lower than the traditional group(P＜0.05).The height of the upper and lower alveolar bones in the traditional group decreased compared with that before orthodontic treatment(P＜0.05),and the invisible group was higher than the traditional group(P＜0.05).The alveolar bone density in the tra-ditional group decreased compared with that before orthodontic treatment(P＜0.05),and the bone density on the lingual side of the alveolar ridge was higher than that in the traditional group(P＜0.05);The cosmetic effect scores of the two groups of patients increased compared with that before orthodontic treatment,and the invisible group was higher than the traditional group(P＜0.05).There was no significant difference in the incidence of complications between the two groups(P＞0.05).Conclusion The use of non-bracket invisible aligners for orthodontic treatment of severe periodontitis patients has minimal impact on the periodontal and alveolar bone,and overall high aesthetic appeal,which is worthy of recommendation.
