Effect of different static surgical guided systems on the accuracy of implant position in esthetic zone

Abstract

Objectives To evaluate the effect of different surgical guided systems on the accuracy of single implant placement in the anterior zone. Methods Twenty operators were divided into two groups by the system they performed in the experiment (Straumann Guided Surgery®; SG and Astra Tech Guide Surgery®; AG). One operator placed one implant on the right central incisor using a computer-guided template that had been planned with 3Shape Implant Studio® program. After the implant installation process was completed, all models were scanned and determined the placed implant position. The amount of coronal, horizontal, vertical, and angular deviation of planned and placed implant positions was statistically analyzed using the Mann-Whitney U test to investigate the influence of two different surgical guided systems. Results The different guided surgery systems had no statistically significant effect on the accuracy of a single implant position except for the 3D coronal deviation. Moreover, the sleeve-on-drill concept resulted in a significantly greater coronal error when compared to the sleeve-in-sleeve concept (P < 0.05). Conclusion Within the limitations of this study, the use of a step-by-step computer-guided surgery assists the operator to place an implant with reliable accuracy in any system. However, the different systems with different concepts had effects on the 3D deviation at implant platform.
