Abstract Objective To observe the clinical effects on posterior region of the crown root ratio（CIR）of different short implants.Methods 97 patients with 154 short implants of single-restoration in posterior from December 2011 to March 2013 were included in the study.All were divided into 3 groups by its CIR:group A0≤CIR≤1.0，group B 1＜CIR＜2.0，group C CIR≥2.0.During 36 months after restoration，the patients were detected cumulative survival rate，mechanical complication and marginal bone level around the implant.Results During the follow-up period of 3 years，the cumulative survival rate of 154 short implants was 95.4%，and there was no significant difference among the groups（P＞0.05）.There was no significant difference in mechanical complications and marginal bone level around the implant among the groups （P＞0.05）.Conclusion Remaining posterior area different CIR short implant rate had no significant difference，can obtain good clinical effect，but the long-term effect remains to be seen.
