摘　　要：种植冠的形状与种植体的机械受力大小密切相关,种植冠不同的颊舌径、牙尖斜度设计,会使种植牙在行使咬(牙合)功能时引起种植体与种植体周围骨组织应力变化,周围骨质的重建和吸收也会因此而发生改变。综述种植冠减径和不同牙尖斜度设计对种植体及周围骨组织应力分布的相关研究进展,以期为临床合理设计种植冠的形状,减小种植体的受力,使种植体生理生存,预防种植体周围炎,长期稳定提供参考。The shape of the implant crown is closely related to the magnitude of mechanical forces on the implant.Different buccolingual diameters and cusp inclinations of the implant crown can cause changes in stress distribution in the implant and surrounding bone tissue when the dental implant performs occlusal function,and the reconstruction and resorption of the surrounding bone will also be altered accordingly.This review summarizes research progress on the effects of reduced diameter of implant crowns and different cusp inclinations on the stress distribution in implants and surrounding bone tissue,with the aim of providing a reference for clinically rational design of implant crown shapes,reducing forces on implants,ensuring the physiological survival of implants,preventing peri-implantitis,and achieving long-term stability.
