钛基牙种植体早期植入稳定性

钛(Ti)及其合金作为20世纪末兴起的种植体材料，具有高强度、低重量、生物相容性好等优势，随着种植体技术的快速发展以及临床上需求的不断增加，Ti种植体迅速且广泛的应用于骨科治疗之中，特别是针对牙缺损的修复。然而，由于骨整合速率缓慢、细菌感染以及过量活性氧累积等多种因素导致种植体早期植入稳定性差，致使植入人体后服役寿命短，成为限制牙种植体植入成功率的重要因素。因此，种植体的临床早期植入稳定性有待进一步提高。从影响临床早期植入稳定性的材料因素、生物因素以及其它因素等3个方面，综述国内外Ti基牙种植体的相关研究，以及提高临床早期植入稳定性的研究现状和发展动态，为牙种植体植入成功率的提高提供参考。

Early Implantation Stability of Titanium Abutment Dental Implants

Titanium (Ti) and its alloys, as implant materials emerging at the end of the 20^th century, have the advantages of high strength, low weight, and good biocompatibility. With the rapid development of implant technology and the increasing clinical demand,Ti implants have been quickly and widely used in orthopedic treatment, especially for the restoration of tooth defects. However, due to various factors such as slow osseointegration rate, bacterial infection and the accumulation of excessive active oxygen, the early implantation stability of the implant is poor, resulting in a short service life after implantation in the body, which has become an important problem limiting the success rate of dental implant implantation. Therefore, the early clinical implantation stability of implants needs to be further improved. Starting from three aspects of material factors, biological factors and other factors that affect the stability of early clinical implants, this article reviews the research status and development trends ofTi-based dental implants to improve the stability of early clinical implants and provides a reference for the improvement of the success rate of dental implants.
