Abstract: Objective To investigate the accuracy error of dental implant robots in immediate and delayed implantation. Methods Implant patients who met the requirements of implant restoration treatment were divided into two groups: immediate implant (n=4) and delayed implant (n=6). Each group was implanted with a dental implant robot. Preoperative CBCT, implant position design, surgical procedure planning, robotic arm registration and alignment were routinely performed, and implant socket preparation and implant placement were performed by the robot. The implant placement error was analyzed by CBCT after surgery. Results The dental implant robot surgery was successfully completed, and there were no complications during and after the surgery. The deviation of the implant depth at the apical point was (0.25±0.13) mm in the immediate the implant group and (-0.88±0.49) mm in the delayed implant group, and the deviation of the implant angle was 1.38°±0.14° in the immediate implant group and 0.59°±0.08° in the delayed implant group. There was a statistical difference between the two groups (P<0.05). Conclusion The dental implant robot showed good accuracy in both immediate and delayed implantation. The accuracy of the implant point and the apical point of the dental implant robot during immediate implantation is close, and the angle deviation is greater than that of the delayed implant.
