Abstract
Implant surgery with surgical guide has been introduced with a concept of prosthetic driven implant. The surgery might be considered as easy even for inexperienced clinician because of step simplicity with high precision of implant and the final prosthesis. The aim of the present study was to evaluate the accuracy of implant placement in the jaw bones as related to two types of surgical guide’s software blue sky bio and Digital Dental Service–Professional after preoperative CBCT. In total, 7 patients (4 men and 3 women; mean age range 50 ± 28 years) with missing teeth. All drillings and placements were performed using surgical guides. After postoperative CBCT a special image-processing software using the 3-matic software matching preoperative planning images with postoperative data was performed. Finally, the bone and teeth volume was removed, leaving the planned and placed implant volumes superimposed on the identical 3D spatial image. The parameters of accuracy were angular deviation (angle between the axis of the planned and placed implants) and linear deviation at the implant shoulder (distance between the coronal centers of the planned and placed implants) and implant tip (distance between the center tip of the planned and placed implants) will measure. Also, the final position of the implants in the software was recorded for postoperative comparison.
