[Complications related to axial orientation of implants and their research progress].

The ideal axial orientation of implant is the key to the success of implant denture restoration. According to the restoration-oriented concept of implant, the implant axis direction should be consistent with the long axis direction of the suprastructure. In clinical practice, implant axial deviation leads to related complications, such as implant fracture, periimplant inflammation, and poor esthetic outcome of implant restoration, resulting in implant treatment failure. In this paper, complications related to improper implant axial orientation, their causes and treatment strategies are reviewed.理想的种植体轴向是种植义齿修复成功的关键，依照以修复为导向的种植概念，种植体长轴方向应与二期修复牙冠的长轴方向一致。在临床实际操作中，种植体轴向偏差可引发相关并发症，如种植体折裂、植体周炎、种植修复美学效果不佳等，进而导致种植治疗失败。本文就与种植体轴向不当相关并发症及其原因、处理对策进行综述。.
