摘要: 目的: 探讨不同牙周表型对正畸微种植支抗钉稳定性的影响。方法: 筛选100例骨性Ⅱ类错牙合年轻女性患者,其中薄龈型50例,厚龈型50例,以上患者均拔除上颌双侧第一前磨牙,并在上颌第二前磨牙和第一磨牙之间植入微种植钉加强支抗,即刻加力,力值200 g,记录6个月后两组菌斑指数(PLI)、龈沟出血指数(SBI)、探诊深度(PD)以及成功例数并进行对比分析。结果: 薄龈型组微种植支抗钉PLI、SBI、PD以及微种植钉周围炎发生率均高于厚龈型组(P<0.05),微种植支抗钉稳定性显著低于厚龈型组(P<0.05)。结论: 牙周表型是影响正畸微种植钉稳定性的重要因素,薄龈型者稳定性显著低于厚龈型者,此结果可用来指导正畸医生临床实践。

Abstract: Objective: To investigate the effect of different periodontal phenotypes on the stability of orthodontic mini-implants. Methods: One hundred young female patients with skeletal class Ⅱ malocclusion were selected, including 50 cases of thin phenotype and 50 cases of thick phenotype. These patients were extracted 2 first premolars and implanted mini-implants between the second premolar and the first molar in the maxilla, both were loaded with 200g immediately. Plaque index(PLI), sulcus bleeding index(SBI), probing depth(PD), and the number of successful cases of two groups were compared and analyzed. Results: The values of related indexes and the incidence of peri-implantitis in thin phenotype group were significantly higher than those in the thick group (P<0.05), and the stability of thin phenotype was significantly lower than that in the thick phenotype group (P<0.05). Conclusion: Periodontal phenotype is an important factor affecting the stability of orthodontic mini-implants, and the stability of thin phenotype is significantly lower than that of the thick group, which is a guide for orthodontists' clinical practice.
