Abstract： Objective To compare the difference of restoration effects between digital intraoral scanning technology and conventional impression of silicon rubber for implant restoration of the posterior teeth.Methods  In this study，62 patients undergoing implant restorations for the posterior teeth were enrolled.43 patients accepted 3Shape intraoral scan to get digital impressions（direct group），while 43 patients were treated by conventional impression technology（control group）.A satisfaction survey and VAS value scale was conducted after treatment for 2 weeks.The check and evaluation were conducted according to the adapted USPHS standards after treatment.Results  The patients in the oral scanning group were more satisfied and more comfortable. In the USPHS score of the two groups， except for the A-level ratio of marginal fitness of the prosthesis in the oral scanning group was higher than that in the control group， there was no significant difference in the A-level ratio of other indicators （P>0.05）. Conclusion  The application of intraoral scanning technology in the preparation of implant restoration has good repairing effect，high precision and high patient satisfaction.It is worth popularizing in clinic.
