Oral rehabilitation with dental implants has resulted in high success rates. However, some complications have been described, such as the loss of the prosthetic screw. Some manufacturers sell screws with different coatings to avoid screw loosening, but even these types of screws can come loose. We aimed to investigate the screw coatings that can be applied during a dental appointment to avoid screw loosening. Following PRISMA Guidelines, we searched PubMed/Medline, Embase and Web of Science for studies published up to January 2024. All studies of single dental implant crowns, in which the prosthetic screw was coated with a lubricant and the preload and/or the removal torque value (RTV) was recorded, were analyzed. We excluded studies applying the finite element method (FEM) as well as studies without a control group. The risk of bias was assessed with a tool developed by our research group. Of the 1959 records identified, 19 were selected. Ten studies were considered to have a low risk of bias, and nine were considered to have a medium risk of bias. The coatings tested were adhesives, saliva, chlorhexidine, Vaseline, silicone gel, Polytetrafluoroethylene (PTFE) tape, blood, fluoride, Listerine Mouthwash and normal saline. The preload, the RTV with and without cyclic loading and the percentage of RTV loss were recorded. Some coatings show promise, although there is no clear evidence that any option is superior in minimizing screw loosening.
牙种植体口腔修复术已取得了很高的成功率。然而，也有一些并发症被报道，比如修复螺丝的松动。一些制造商出售带有不同涂层的螺丝以避免螺丝松动，但即便这类螺丝也可能会松动。我们旨在研究在牙科就诊过程中可应用的能避免螺丝松动的螺丝涂层。按照PRISMA指南，我们在PubMed/Medline、Embase和科学网中检索截至2024年1月发表的研究。对所有单颗牙种植体牙冠的研究进行分析，这些研究中修复螺丝涂有润滑剂，并记录了预紧力和/或拆卸扭矩值（RTV）。我们排除了应用有限元法（FEM）的研究以及没有对照组的研究。使用我们研究小组开发的工具评估偏倚风险。在识别出的1959条记录中，选取了19条。10项研究被认为偏倚风险较低，9项被认为偏倚风险中等。所测试的涂层有粘合剂、唾液、洗必泰、凡士林、硅胶、聚四氟乙烯（PTFE）胶带、血液、氟化物、李施德林漱口水和生理盐水。记录了预紧力、有无循环加载时的RTV以及RTV损失百分比。一些涂层显示出了前景，尽管没有明确证据表明在最小化螺丝松动方面有任何一种选择更具优势。
