摘要目的探讨牙种植体的冠体比(C/I)对种植体周边骨的影响及导致骨丢失的局部影响因素。方法评估了160例病人的240个种植体,平均随访3.8年。将其按种植体的冠体比(C/I)分为:<1组和≥1组。局部影响因素按种植体的位置、直径、类型进行分组比较。结果与冠体比≥1组相比,冠体比<1组的周边骨丢失更为明显;局部因素对周边骨丢失也有影响;与局部影响因素相比,冠体比对周边骨丢失的影响更显著。结论冠体比较高的牙种植体其周边骨丢失较少,并且是影响其周边骨丢失的重要因素。 Objective Few studies were done for the effect of crown implant ratio on the peripheral bone loss.In this study,we explored the effect of crown implant ratio（C/I） on the peripheral bone loss and its impact factors.Methods 160 patients with 240 implants were evaluated,average follow-up for 3.8 years.According to C/I ratio,they were divided into two groups： C/I1 and ≥1.Local impact factors were grouped and compared by location,diameter and type of implant.Results compared with the group with C/I ratio of ≥1,those in C/I ratio 1 had more peripheral bone loss.The local factors had impact on peripheral bone loss as well： compared with local impact factors,C/I ratio had more significant impact on peripheral bone loss.Conclusion Implant with high C/I ratio had less peripheral bone loss.C/I ratio is an important factor affecting peripheral bone loss.
