摘要目的：应用锥形束CT（conebeamcomputertomography，CBCT）测量慢性牙周炎患者在正畸治疗前后的牙槽骨高

度，探讨正畸治疗对慢性牙周炎患者牙槽骨高度变化的影响。方法：应用CBCT测量222颗轻、中度牙周病患牙正畸治疗前后牙

槽嵴顶到釉牙骨质界（cemento-enameljunction，CEJ）的距离。结果：全口6个区域24个位点比较，有7个位点即上前牙近远中位

点、上前磨牙近中位点、上磨牙近中位点、下前牙颊舌侧位点、下前磨牙近中位点牙槽嵴顶到CEJ的距离治疗前后比较差异均

具有统计学意义（P0.05）；其余17个位点牙槽嵴顶到CEJ的距离治疗前后比较差异均无统计学意义（P0.05）。结论：牙周病

患者结合正畸治疗时不会引起明显的牙槽骨吸收。
