Abstract: Objective: To study the changes and correlation of serum CRP and urine DPd content for different periods (1 day before operation, 1 month after operation, and six months after operation). Methods: Totally 86 cases of implant restoration in patients between 25-45 years old, without periodontitis and chronic disease, were enrolled in the study. The serum CRP and urine DPd of the patients 1 day before operation (A1 group), 1 month after the operation (A2 group) and half year after the operation (A3 group) were collected. Results: Compared with A1 group, serum CRP in A2 group was significantly increased while in A3 group showed a downward trend (P<0.05). The serum CRP level in A2 group was significantly higher than the other two groups (P<0.05). Though the serum CRP level in A3 group was higher than A1 group, there was no statistical significance (P>0.05). As compared the levels of urinary DPd, A1 group was significant lower than A2 and A3 groups and the data of A2 group was the highest (P<0.05). There was statistical difference among three groups of the overall mean. Serum CRP was positively correlation with urinary DPd by statistical analysis (P<0.001). Conclusion: Serum CRP and urine DPd content would increase in the active stage of alveolar bone remodeling during the implant restoration process. There was a significant correlation between two indices. Serum CRP and urinary DPd could be regarded as an index reflecting alveolar bone resorption and remodeling
