Abstract
The present study was designed to compare the accuracy between the virtual and the actual implant position using surgical guide vs free handed. This study was conducted on two model with three implants for each divided into two groups: First group: implants placement by surgical guide. Second group: implants placement by free handed. CBCT scanning with virtual implant planning were used to develop a computer based surgical guide which was used to place the implants. Models were scanned by CBCT after insertion to compare the accuracy of planned position and actual position of implants placement by guided surgery versus free handed technique. Linear and angular deviations were measured between planned and actual position in both groups. After results were tabulated and statistically analyze to reach a conclusion that there was no statistically difference in linear lateral and global deviation and angular deviation in buccolingual direction and mesiodistal direction between both groups coronally and apically
