Objective:To explore the effect of full digital process restoration of implant single crown in the posterior area and the influencing factors of complications.Methods:168 patients with implant crown restoration in the posterior area were randomly divided into experimental group(full digital process restoration)and control group(conventional restoration).The success rate,2-year survival rate and complications of the two groups were compared.The factors influencing the occurrence of complications were analyzed.Results:Compared with the control group,the experimental group had higher implantation success rate,2-year retention rate and lower total incidence of complications(P<0.05).Periodontitis history,bad occlusal habits and implant length≥10mm were independent risk factors for complications,and full digital process restoration was the protective factor.Conclusions:The full digital process of dental implant crown restoration in the posterior area is effective.Clinical intervention can be given according to the influencing factors of complications to reduce the incidence.
