提高正畸治疗牙移动速率，缩短疗程是正畸患者及医生的迫切要求。低强度激光（LLL）因具有抗炎、镇痛、促进组织愈合和无创伤等优点，在医学领域得到广泛运用。近年来，大量基础研究发现LLL能影响机体的成骨及破骨效应，提高实验动物牙移动速率，相关的临床试验报道也证实了其促进患者正畸牙移动的有效性。本文就LLL促进正畸牙移动的基础和临床研究进展作一综述。

From the perspective of patients and orthodontists, accelerating teeth movement is desirable because the treatment duration is very long. The harmless and infection-free low-level laser(LLL) is highly capable of suppressing inflammatory process, reducing pain, and promoting wound healing. Thus, LLL is widely utilized in several different treatments in clinical practice. Researchers have studied the effects of LLL, and found that this method can accelerate alveolar bone remodeling and increase the rate of tooth movement in animals. Several clinical trials have also enhanced the efficiency of LLL in accelerating the velocity of orthodontic tooth movement. In this article, recent experimental and clinical studies on the mechanism through which LLL improves orthodontic tooth movement are reviewed.
