摘　　要：目的:分析不同牙龈生物型对上颌埋伏尖牙正畸牵引后牙周组织的影响。方法:选择符合纳入标准的单侧埋伏尖牙患者24例,依据对侧尖牙牙龈厚度分为薄龈生物型组和厚龈生物型组,每组各12例。测量治疗后埋伏尖牙和对照尖牙的根尖牙槽骨厚度、唇侧牙槽骨厚度、唇侧牙槽骨高度和附着龈宽度,并计算埋伏尖牙与对照尖牙的各测量项目差值,比较两组间差异。结果:治疗后两组患者埋伏尖牙和对照尖牙的各测量项目间差异均有统计学意义(P<0.05)。薄龈生物型组患者埋伏尖牙与对照尖牙的唇侧牙槽骨厚度差值、唇侧牙槽骨高度差值和附着龈宽度差值,均大于厚龈生物型组(P<0.05)。结论:厚龈生物型更有利于上颌埋伏尖牙正畸牵引后的牙周组织健康。Objective:To study the influence of different gingival biotypes on periodontal tissue of maxillary impacted canines after orthodontic traction.Methods:Twenty-four patients with unilateral impacted canines were divided into thin gingival biotype group and thick gingival biotype group(n=12 for each group)according to the gingival thickness of the contralateral canine.After treatment,the apical alveolar bone thickness,labial alveolar bone thickness,the loss of labial alveolar bone height,and gingival attachment width of impacted canines and control canines were measured.Results:The differences of any measurement variables between two groups were significant after the treatment(P<0.05).The differences of the labial alveolar bone thickness,the loss of labial alveolar bone height,and gingival attachment width between the impacted canines and the control canines in the thick gingival biotype group were smaller than those in the thin gingival biotype group(P<0.05).Conclusion:The thick gingival biotype is more beneficial to the reconstruction of periodontium for maxillary impacted canine after orthodontic traction.
