Practitioners’ experience may affect the accuracy of freehand implant surgery other than guided surgery
As showed in this study, the coronal and apical distance and the angular deviations were significantly higher in Group SFH than IFH, while not significantly different between Group SSG and ISG.The surgeon’s experience is a determinant for the accuracy of ideal implantation, particularly when implants are placed freehand without any surgical template or navigation system. The results of this study were in accordance with several studies which implicated that experience was a decided factor for implantation success, whereas others showed no significance with the assistance of the guided system [An in vitro study by Park et al. demonstrated that the use of a CAD/CAM surgical guide reduced discrepancies among operators performing implant surgery regardless of their level of experience, and the differences of the anterior–posterior implant sites in the molar areas did not affect the accuracy of implant placement [
