J Cin Periodontol:正畸治疗时机对IV期牙周炎患者牙周再生手术结果的影响

IV期牙周炎的主要临床特征是严重的牙周附着丧失、垂直骨吸收和病理性牙齿迁移(PTM)。需要一种跨学科的方法来控制牙周感染,重建骨并重新排列迁移的牙齿。

IV期牙周炎的主要临床特征是严重的牙周附着丧失、垂直骨吸收和病理性牙齿迁移(PTM)。需要一种跨学科的方法来控制牙周感染,重建骨并重新排列迁移的牙齿。

综合治疗包括牙周治疗的洁治、刮治、牙周再生手术和随后的正畸治疗(OT)。然而,关于这些牙周再生和正畸组合方法的数据有限。特别是,牙周手术和OT之间的最佳时间间隔是一个正在争论的问题。

本实验旨在比较牙周炎骨内缺损(ID)牙周再生手术后早期(手术后4周)或晚期(手术后6个月)正畸治疗(OT)后的结果。

本实验是一项多中心、平行组、随机临床试验,共43名IV期牙周炎患者随机接受ID再生手术后的早期(n=23)或晚期OT(n=20)。检测术后12个月时ID的临床附着水平(CAL)的变化,并检测牙周袋探诊深度(PPD)、探诊出血(BOP)和牙周袋闭锁率。

结果发现,在CAL增加(早期OT 5.4mm±2.1mm和晚期OT 4.5mm± 1.7mm),组间没有显著的统计学差异。早期组PPD减少4.2 mm ±1.9 mm,晚期组减少3.9 mm ±1.5 mm (p> 0.05)。在早期OT组,91%的缺损获得了牙周袋闭锁 (PPD ≤ 4 mm),而在晚期OT中则为85%。

因此,在IV期牙周炎治疗时,可在ID再生手术4周后开始OT,效果良好,并且缩短了整体治疗时间。
