Abstract
Dental implant placement requires precise planning with regard to anatomic limitations and restorative goals. The aim of the study was to evaluate the accuracy of the cone beam computed tomography guided surgical stents for implant placement by comparing the virtual and the real implants positions regarding the linear and angular deviations. Patients and method: Four patients were selected and were preoperatively scanned using CBCT scanner. For those patients, ten implants were planned to be placed. After the virtual planning was finished, the surgical guide was designed for each patient. Following drilling while the corresponding surgical templates in place and implant placement, post-operative CBCT scans were performed and position of the real implants was compared to that of the virtual ones. Horizontal deviation of the was measured at the coronal and apical ends of each implant on axial views. Angular deviation between the long axis of the virtual and real implants was also measured on selected cross sectional & reformatted panoramic views. All results were statistically analyzed
