摘要
Abstract
Objective To evaluate the effect of extraction site preservation in the maxillary anterior aesthetic zone of patients with StageⅢ orⅣ,Grade C periodontitis.Methods A total of 80 patients who were required extraction of anterior maxillary teeth due to chronic periodontitis and were treated at Saisi Stomatological Hospital of Henan University from January 2022 to June 2024 were retrospectively included.Among them,40 patients were assigned to the experimental group and underwent minimally invasive extraction followed by extraction site preservation,while 40 patients were assigned to the control group and underwent only minimally invasive extraction.Changes in the three-dimensional contour of the alveolar bone before and after treatment,as well as postoperative pain assessed by the visual analogue scale(VAS),were compared between the two groups.Results At 6 months postoperatively,compared with the immediate postoperative CBCT measurements,the vertical height of the alveolar bone decreased in both groups,but the decrease was significantly less in the experimental group than in the control group(P=0.0060).At 2 mm apical to the alveolar crest,both groups exhibited horizontal bone resorption,but the experimental group showed significantly less resorption(P=0.0008).At 4 mm apical to the alveolar crest,both groups showed an increase in horizontal bone width,with the experimental group showing a significantly greater increase than the control group(P=0.0390).Over time,VAS pain scores decreased in both groups.At 3 days and 7 days postoperatively,VAS scores in the experimental group were significantly lower than those in the control group(3 days:P=0.0007;7 days:P=0.0050).Conclusion Extraction site preservation can significantly reduce the resorption of alveolar bone height and width following extraction of anterior maxillary teeth in patients with chronic periodontitis,thereby providing favorable conditions for subsequent prosthetic rehabilitation.In addition,it can alleviate postoperative pain.关键词
