Abstract: PURPOSE: To evaluate the accuracy of 3D printed guide plate in implantation of upper anterior teeth and to explore its clinical effect. METHODS: Sixty patients who underwent upper anterior dental implantation from June 2017 to June 2018 were randomly divided into two groups: group G(guide plate group)and group R(conventional group). Each group had 30 patients. Cone-beam CT (CBCT) was taken before operation, and guide plate software Dentiq Guide was used to design the guide plate. Group G used 3D printed guide plate to assist implantation, while group R underwent conventional implantation. CBCT was taken immediately after operation. Preoperative and postoperative CT were overlapped by Dentiq Guide implant guide software. The differences between preoperative design and actual implant position were measured and the data were analyzed statistically with SPSS 24.0 software package. RESULTS: Forty-six implants were implanted in group G. The measured deviation was: angle (2.34±1.03)°, tip (0.63±0.38) mm, apex (0.71±0.38) mm, and depth (0.41±0.40) mm. In group R, 43 implants were implanted with the following measured deviation: angle (6.72±3.65)°, tip (1.59±0.35) mm, apex (2.05±0.92) mm, and depth (0.77±0.63) mm. There were significant differences in angle, tip, apex and depth between two groups (P<0.05). CONCLUSIONS: Application of 3D printed guide plate in assisting implantation of upper anterior teeth can improve the accuracy of operation, meet the needs of implant restoration, and practise the concept of precise implantation guided by restoration.
