Abstract:Abstract: Objective To investigate the relationships between inflammation-related indexes and prognosis of implant after oral implant repair. Methods Fifty patients with dental implant repair in our hospital from January 2014 to November 2015 were enrolled in this study as the experiment group while 50 healthy adults were enrolled as the control group. CRP, urine deoxypyridinoline/serum creatinine (UDPd/Scr) ratio, white blood cells, interleukin-1 (IL-1), IL-6 and tumor necrosis factor-alpha (TNF-α) were detected 1 week before operation, 1 week and 1 month after operation. Results Compared with the control group, the CRP, IL-1, IL-6 and TNF-α levels, and UDPd/Scr ratio were significantly elevated in the experiment group at 1 week and 1 month after operation (P < 0.05). One month after operation CRP was significantly associated with UDPd/Scr ratio (r = 0.298, P < 0.05). The levels of CRP, UDPd/Scr, IL-1, IL-6 and TNF-α in the patients with poor osseointegration were higher than those in the patients with good osseointegration (P < 0.05). Conclusions CRP, UDPd/Scr, IL-1, IL-6 and TNF-α levels are related to the prognosis of dental implant.
