Abstract: Objective To introduce and evaluate one kind of novel cementing technique of implant restoration in the esthetic zone. Methods 60 cases of anterior cemented implant restorations were included. The cement margins of these restorations were located 1 to 1.5 mm under gingival margin. A novel cementing technique was introduced in experimental group while conventional cementation technique was applied in the control group. mSBI, PD and cementation failure rate were recorded and evaluated 1 month and 6 months respectively after cementation. Results 1 month after cementation, the mSBI of experimental group was statistically lower than that of control group, while no statistically significant difference was found in other parameters. 6 months after cementation, there was no statistically significant difference in any parameters between two groups. Conclusion The special cementation technique is helpful to reduce the possibility of periimplantitis caused by excess cement in the early phase and to enhance the gingival health.
