Abstract

Abstract: Objective To study the one year clinical effect of guided bone regeneration (GBR) of implant placement in the molar sites. Methods 55 patients were selected from August 2017 to July 2019, 58 implants were implanted, of which 29 were set as experimental with simultaneous implant placement and GBR, 29 patients were selected as control group. The survival rate, marginal bone loss (MBL), gingival index (GI) and probing depth (PD) were compared between the two groups. Results SPSS 20.0 was used to make statistics. Results The survival rate of implants in control group and experimental group was 100%; There was no significant difference in bone absorption at the margin; The gingival papilla index of experimental group was better than that of the control group (P<0.05), and there was no statistical difference in GI and PD between the experimental group and the control group. Conclusion The simultaneous implant placement in the molar sites with GBR can increase the height of the implant and the adjacent bone of the natural teeth and improve the filling degree of the gingival papilla.
