The immediate restoration of dental implants has sh own revealed the clinical success rates compare with conventional multi-step protocol. However, the accuracy of guided dental implant placement using guided trephine drill and the restoration affect th e treatment success and more security. To provide t he professional tool improve the planning to choose th e implant size and position. The objectives of this study were to evaluate the accuracy and position of the digital surgical guide before and after implan t placement with the guided trephine drill. The digit al process chain work from Intra oral scan with denture will be performed. And then cone beam compu ter tomography (CBCT) with gutta-percha marker denture. The virtual prototyping precisions of 5 st ereolithographic surgical splints are validate a de sign before committing to making the rapid prototype wer e excellent. The satisfaction score compare with the conventional splint and provisional crown impro ve in term of time and esthetic outcome. The guided trephine drill can reduce the stage of bone augmentation. The mean measurement differences in accuracy between the computer-planned implant and t he before and after surgery for 6 implants guided placed were 1.18 mm for the apex (SD+/- 0.37), 0.35 mm for the mesial (SD+/-1.2) 0.35 mm (SD+/-1.5), f or the depth deviation. The results show a statistical ly significant difference of the implant placed bet ween the conventional and the virtually planed implant p ositions with the CAD/CAM-guided surgical template
