Abstract

Abstract: Objective: To evaluate the accuracy of registration of oral implant robot using five kinds of intraoral scanners. Methods: The registration process of robot-assisted implant surgery was completed by using the oral scanning registration method and the cone beam computed tomography (CBCT) registration method, respectively. The oral scanning registration method used five different intraoral scanners, and then two implants were implanted in the mandibular dentition defect model under the guidance of the robot. CBCT was taken after operation for deviation analysis. The main analysis indexes were implant angle deviation and total deviation of implantation point and apical point. Results: The registration accuracy of the robot under five different intraoral scanners was not statistically significant in implant angular deviation, implant depth and level deviation, and apical depth and level deviation (P>0.05). The total deviation of the entry point and the total deviation of the apical point were statistically significant (P<0.05). Conclusion: The accuracy of oral implant robot registration using five kinds of intraoral scanners can achieve good clinical results, but the registration accuracy of different intraoral scanners is different.
