Abstract: Objective To analyze the bone remodeling around the implant in patients with chronic maxillary sinusitis after the osteotome sinus floor elevation (OSFE). Methods 60 patients with implant restoration in the posterior maxilla area by OSFE from January, 2015 to June, 2016 in our department were selected retrospectively in this study. They were divided into two groups according to the mucosal thickness. Changes in marginal bone level over time were observed. Results By the Independent sample t test, the apical bone height (ABH) and marginal bone loss (MBL) was compared between the two groups at 6 months and 3 years after surgery. There was no statistically significant difference in ABH and MBL between the two groups (P>0.05). 3 years after surgery, the VBG in the inflammation group was significantly lower than that of the control group, and the difference was statistically significant (P<0.05). Conclusion For patients with chronic maxillary sinusitis, it is feasible to use the Osteotome sinus floor elevation, and the prognosis is good.
