Abstract 【Objective】To investigate the effect of immediate load and tilted implant in the restoration of tooth loss. 【Methods】From January 2015 to January 2017, 18 patients were prospectively selected. All patients were followed up for 3 years, staring from 6 months after surgery. Various indexes were recorded immediately after load (T₀), 6-month (T₁), 1-year (T₂) and 3-year (T₃) after treatment. There included marginal bone levels (MBLs), mid-buccal mucosal levels (MBMLs), implant success rate, implant stability quotient (ISQ), prosthodontic maintenance, prosthodontic complications, pink esthetic score (PES), and white esthetic score (WES). Then the aesthetic effect was discussed. 【Results】Of the 18 patients, 4 cases did not have complete follow-up records (1 implant failed before restoration, 1 case had bilateral first molars missing, and 2 cases were lost to follow-up). The remaining 14 cases with a total of 15 single implant crowns finished 4 years follow-up. The success rate of implant was 93.33% during the 3-year follow-up period (14/15). Compared to the data at T₀, the value of MBLS and MBMLs increased at T₁, T₂ and T₃ (P<0.05); and MBMLs value increased at T₂ and T₃ compared to T₁ (P<0.05), however, the value of MBLS and MBMLs at T₂ showed no significant difference compare to T₃ (P>0.05). ISQ values of mesial and distal papilla at T₁, T₂ and T₃ were lower than those at T₀ (P<0.05),while the values at T₂ and T₃ had no obvious changes, which showed no significant different from those at T₁ (P>0.05). Compared to T₀, the RES and WES scores at T₁, T₂, and T₃ were significantly higher, and the difference was statistically significant (P<0.05). After that, the RES and WES scores at T₂ and T₃ changed slightly, and there were no statistical differences compared to T₁ (P>0.05).At T₁, there were some prosthodontic maintenance issues involving the definitive implant crowns which included fracture of veneering ceramic and zirconia abutment as well as aesthetic concerns. At T₂ and T₃, there were no further prosthodontic maintenance issues reported and no screw loosening was evident. During the 3-year follow-up period, RES and WES had no significant changes. There were 1 case of implant loosening, 1 case of abutment pain and 1 case of gingivitis, all of which were significantly improved by active treatment. 【Conclusion】Application of immediate load and tilted implant in single-tooth implant restoration has high success rate and aesthetic effect.
