Background This in vitro study aims to evaluate the accuracy of dental implant placement by a novel image‐guided hybrid robotic system for dental implant surgery (HRS‐DIS). Methods The HRS‐DIS with a 5 degree of freedom (DOF) serial manipulator and a 6 DOF Stewart platform was developed. To evaluate the accuracy of repeated drilling, the holes were prepared twice with a 2.2 mm drill. To evaluate the accuracy of dental implant placement, the entry, exit and angle deviations of dental implants were measured. Results Twenty‐four holes were prepared twice, and mean (±SD) of diameters were measured as 2.2 ± 0.02 mm. A total of 160 dental implants were placed in 32 phantoms by HRS‐DIS. The mean (±SD) of the entry, exit and angle deviation were 0.8 ± 0.54 mm, 0.87 ± 0.54 mm and 1.0 1 ± 0.44°, respectively. Conclusions The results of the in vitro study preliminarily validated that the HRS‐DIS could provide a high accuracy for dental implant surgery.
