Abstract: Objective To investigate the effect of digital guided technology on the accuracy of oral implant restoration. Methods 33 patients with oral implant restorations were selected. The digital guided technology restoration was Group A, free-handed implant restoration was Group B . There are 41 implants in group A, and 48 implants in Group B. cone beam computed tomography (CBCT) was used to record and compare the deviation values of the two methods in implant neck, root, depth and angle. Results The implant neck deviation in Group A [(1.50±0.49) mm] was less than that in Group B [(2.15±0.57) mm] (P<0.05).The root deviation in Group A [(1.56±0.56) mm] was less than that in Group B [(2.19±0.50) mm], and the difference was comparable (P<0.05).The depth deviation in Group A [(1.40±0.40) mm] was less than that in Group B [(1.80±0.43) mm], and the difference was comparable (P< 0.05). The angle deviation in Group A (3.39°±0.62°) was less than that in Group B (3.92°±0.55°), and the difference was comparable (P<0.05). There was a statistically significant difference in the anterior and posterior regions using digital guided surgery (P<0.05). There was a statistically significant difference between the implant neck deviation and the root deviation when comparing the three brands of implants using the digital guided technology (P<0.05); while there was no statistically significant difference between the depth deviation and the angle deviation when comparing the three brands of implants using the digital guided technology (P>0.05). Conclusion Using digital technology for dental implant restoration can optimize the precision of implant and improve the quality of restoration.
