| 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。 |

| ObjectiveFew 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.Methods160 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/I＜1 and ≥1.Local impact factors were grouped and compared by location,diameter and type of implant.Resultscompared 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.ConclusionImplant with high C/I ratio had less peripheral bone loss.C/I ratio is an important factor affecting peripheral bone loss. |
