Abstract: PURPOSE: To compare the application effects of 3 kinds of occlusal paper in artificial dental implantation. METHODS: From February 2020 to February 2022, a total of 117 patients in Zhoushan Stomatological Hospital were selected and divided into 3 groups according to the degree of occlusal tightness, with 39 patients in each group, all of which were single implantation. The occlusal paper with a diameter of 12 μm was used in group A, while 20 μm in group B, and 30 μm in group C. The periodontal indexes(peri-implant bone resorption, probing depth around the implant, gingival index, and tooth mobility) were compared among the three groups at 3 months after restoration. The absolute value of occlusal balance index before restoration, on the day of restoration, and at 3 months after restoration were compared, and the satisfaction of patients and physicians was evaluated. SPSS 22.0 software package was used for data analysis. RESULTS: There was no significant difference in periodontal indexes among the three groups (P>0.05). The absolute value comparison of occlusal balance index among the 3 groups showed that 6 months after repair < 3 months after repair < day of repair < before repair (P<0.05). The absolute value of occlusal balance index in group A was significantly lower than that in group B and group C 3 months after repair(P<0.05). The satisfaction of patients and doctors in group A was significantly higher than that in group B and C (P<0.05). CONCLUSIONS: Compared with 20 μm and 30 μm occlusal paper, the application of 12 μm occlusal paper in artificial dental implant restoration can adjust the occlusal balance and improve the satisfaction of patients and doctors.
