Abstract：Objective The 3shape Trios intraoral intraoral scanner combined with 3D printing technology is used to make single crown restoration,determine its feasibility,and discuss and evaluate the clinical effectiveness and patient satisfaction.Methods In this study,32 patients whose single premolar teeth needed crown restoration were included and divided into two groups randomly:the experimental group(16 patients)and control group(16 patients).In the experimental group,the restorations were made by 3 shape Trios and 3D printer.As for the control group,the regular design method was applied to restore their teeth.The time consumed in the first insertion of each restoration in both groups was recorded.The quality of the prostheses was assessed by another dentist.The prostheses satisfactions were evaluated by the patients.Results The acceptance rate of the patients on the digital rehabilitation in the experimental group was 100％.There was no significant difference in the quality of the prostheses between the two groups.The satisfaction rate of the patients on prostheses and facial appearance was significantly higher in the experimental group than in control group (P ＜ 0.05).In addition,the time consumed in the first insertion of the experimental group was much shorter than that in the control group (P ＜ 0.05).Conclusion The new method of the 3shape Trios scanner combined with 3D printer for making single crown is a practical technique.This method is useful in shortening the time consumed in the restoration of single crown,improves the patient satisfaction of the prostheses.
