Comparative Analysis of the Effect of Immediate and Early Extraction Site Preservation in Patients with Chronic Periodontitis
Objective To analyze the difference between immediate and early extraction site preservation of bone mass in patients with chronic periodontitis.Methods A total of 45 patients with posterior teeth with no retention value due to chronic periodontitis admitted to the Stomatology Department of Zhongshan Hospital of Traditional Chinese Medicine from January 2023 to January 2024 were selected and randomly divided into three groups,A,B and C,with 15 patients in each group.Group A was the control group,after tooth extraction,the infected tissue was cleared without site preservation and natural healing was performed.Group B underwent immediate extraction site preservation.Group C underwent early extraction site preservation.All patients in the three groups underwent cone beam computer tomography(CBCT)examination before surgery and 4 months after surgery.The images of the same site were overlaped by imaging software to measure and compare the spatial bone mass of alveolar bone in all dimensions and the changes of bone mass in horizontal and vertical directions.Results Four months after surgery,the spatial bone mass of patients in group C was higher than that in group A and group B,the difference was statistically significant(P<0.05).The changes of horizontal and vertical bone mass in group C were lower than those in group A and group B,and the change in vertical bone mass in group B were lower than that in group A,the differences were statistically significant(P<0.05).Conclusion Both early extraction site preservation and immediate extraction site preservation can maintain bone mass to a certain extent,but early extraction site preservation is less difficult to operate,the operation time is short,and the postoperative reaction is small,therefore,after tooth extraction in patients with chronic periodontitis,the preservation of early extraction site can be preferred as the method of post-extraction site preservation.
