Abstract：
OBJECTIVE: Surgical techniques in orthodontics have received widespread attention in recent years. Meanwhile, biomaterials with high molecular content have been introduced, such as platelet concentrates (PCs), which may accelerate orthodontic tooth movement (OTM) and reduce periodontal damage. The present systematic review aimed to answer the following PICO question: \"In patients in whom orthodontic surgical techniques are performed (P), what is the effectiveness of using PCs over the surgical site (I) when compared to not placing PCs (C) to achieve faster tooth movement (O)?\"
METHODS: A search was performed in 6 databases. The criteria employed were those described in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses declaration. The present review included studies with a control group that provided information about the influence of PCs on the rate of OTM.
RESULTS: The electronic search identified 10 studies that met the established criteria.
CONCLUSIONS: The included studies were very diverse, making it difficult to draw convincing conclusions. However, a tendency was observed for OTM to be accelerated when PCs were used as an adjuvant for canine distalization after premolar extraction when distalization was started in the same session. Likewise, studies seem to indicate an association between PC injection and the amount of canine retraction. However, it is not possible to affirm that the use of PCs in corticotomy shortens the overall treatment time, as this question has not been studied adequately.

摘要：
目的：近年来口腔正畸外科技术受到广泛关注。同时,介绍了高分子量的生物材料,如血小板浓缩物(PC)，这可能会加速正畸牙齿移动（OTM）并减少牙周损伤。本系统综述旨在回答以下PICO问题：“在进行正畸手术技术的患者中（P），与不放置PC(C)相比,在手术部位使用PC(I)的有效性如何,以实现更快的牙齿移动(O)?\"
方法:在6个数据库中进行了搜索.采用的标准是系统审查和荟萃分析声明的首选报告项目中描述的标准。本综述包括与对照组的研究，该研究提供了有关PC对OTM比率影响的信息。
结果：电子搜索确定了10项符合既定标准的研究。
结论：纳入的研究非常多样化，很难得出令人信服的结论。然而,当在同一疗程中开始扩张时，将PC用作前磨牙拔除后犬扩张的佐剂时，观察到OTM加速的趋势。同样，研究似乎表明PC注射与犬回缩量之间存在关联。然而,无法肯定在皮质切开术中使用PC会缩短整体治疗时间，因为这个问题没有得到充分的研究。
