摘要: 目的:分析上颌埋伏尖牙正畸牵引后牙周组织状态与牙龈生物型的相关性,为临床治疗方案优化提供参考。方法:选取2019年10月—2023年10月青岛大学附属医院收治的82 例上颌埋伏尖牙患者,通过数字化影像技术及牙周探针透视法评估牙龈生物型,分为薄龈生物型组(47 例)和厚龈生物型组(35 例)。所有患者均接受正畸牵引治疗,比较两组治疗后牙槽骨厚度、高度、附着龈宽度等牙周组织指标,以及牙周袋深度、临床附着丧失、牙龈指数等牙周健康指标的变化。结果:厚龈生物型组的唇侧牙槽骨厚度、根尖牙槽骨厚度、唇侧牙槽骨高度及附着龈宽度显著大于薄龈生物型组(P<0.05);厚龈生物型唇侧、根尖牙槽骨厚度及高度差值、附着龈宽度差值显著小于薄龈生物型(P<0.05);薄龈生物型组的牙周袋深度、牙龈指数及临床附着丧失显著高于厚龈生物型组(P<0.05)。结论:厚龈生物型患者在上颌埋伏尖牙正畸牵引后,牙周组织形态变化更小,牙周健康状态恢复更优,提示术前评估牙龈生物型对预后判断及治疗方案制定具有重要意义。

Abstract: PURPOSE: To analyze the correlation between the periodontal tissue status and gingival biotype after orthodontic traction of maxillary impacted molars, and to provide a reference for the optimization of clinical treatment plans. METHODS: A total of 82 patients with maxillary impacted canines admitted to Affiliated Hospital of Qingdao University from October 2019 to October 2023 were selected. The gingival biotype was evaluated by digital imaging technology and periodontal probe,and the patients were divided into the thin gingival biotype group(n=47) and the thick gingival biotype group(n=35). All patients received orthodontic traction treatment. The periodontal tissue indicators such as alveolar bone thickness, height, and attached gingival width after treatment, as well as the periodontal health indicators such as periodontal pocket depth, clinical attachment loss, and gingival index were compared between the two groups. RESULTS: The labial alveolar bone thickness, apical alveolar bone thickness, labial alveolar bone height, and attached gingival width in the thick gingival biotype group were significantly greater than those in the thin gingival biotype group (P<0.05); the differences in labial and apical alveolar bone thickness and height, and the difference in attached gingival width in the thick gingival biotype group were significantly smaller than those in the thin gingival biotype group(P<0.05); periodontal pocket depth, gingival index, and clinical attachment loss in the thin gingival biotype group were significantly higher than those in the thick gingival biotype group(P<0.05). CONCLUSIONS: Patients with thick gingival biotype have smaller changes in periodontal tissue morphology and better recovery of periodontal health status after orthodontic traction of maxillary impacted canines, suggesting that preoperative evaluation of gingival biotype is of great significance for prognosis judgment and treatment plan formulation.
