| 目的 研究重度牙周病单颗牙拔除保留骨面分离肉芽组织对牙槽窝成骨效果的影响。方法 选取2022年1月至2023年10月间收治的100例重症牙周病患者为研究对象，随机分为实验组与对照组，每组50例。两组均根据患者影像学以及临床检查结果制定拔牙方案，实验组在单颗牙拔除后，保留骨面分离肉芽组织；而对照组则将其彻底清除。分别于拔牙时和拔牙后3个月，采用影像学方法测量拔牙部位颊舌侧牙槽骨高度、宽度和中央窝骨愈合高度。结果 拔牙后3个月，实验组和对照组的中央窝骨愈合高度分别为(4.87±1.82) mm和(0.37±1.32) mm，实验组高于对照组(P<0.05)。实验组的颊侧骨高度吸收和舌侧骨高度吸收分别为(0.63±0.42) mm和(1.35±1.19) mm，低于对照组的(1.33±0.92) mm和(2.12±1.27) mm(P<0.05)。两组颊舌侧骨宽度度吸收分别为(1.21±0.84) mm和(1.03±0.49) mm，不存在明显差异(P>0.05)。结论 保留骨面分离肉芽组织对重度牙周病单颗牙拔除后牙槽窝成骨有显著效果。 |

| Objective To investigate the effect of preserving bone surface separated granulation tissue on alveolar bone regeneration after the extraction of a single tooth with severe periodontitis. Method From January 2022 to January 2023, 100 patients with severe periodontitis requiring single tooth extraction were enrolled and randomly divided into an experimental group and a control group, with 50 cases in each group. The experimental group underwent tooth extraction while preserving the bone surface and separated granulation tissue, whereas the control group completely removed the granulation tissue. Three months after extraction, cone-beam computed tomography(CBCT) was used to measure the healing height of the central alveolar fossa and the height and width of the buccal and lingual alveolar bone. Results Three months after extraction, the mean healing height of the central alveolar fossa in the experimental group was(4.87±1.82) mm, which was significantly higher than that of the control group(0.37±1.32 mm, P<0.05). The buccal and lingual bone resorption in the experimental group were(0.63±0.42) mm and(1.35±1.19) mm, respectively, both significantly lower than those in the control group(1.33± 0.92 mm and 2.12±1.27 mm, P<0.05). The alveolar bone width on the buccal and lingual sides showed no significant difference between groups(1.21±0.84 mm vs. 1.03±0.49 mm, P>0.05). Conclusion Preserving bone surface separated granulation tissue during the extraction of severely periodontally affected teeth can significantly improve alveolar bone healing and regeneration, suggesting a beneficial effect on bone preservation following tooth extraction in periodontitis patients. |
