The immediate restoration of dental implants has shown 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 the treatment success and more security. To provide the professional tool improve the planning to choose the implant size and position. The objectives of this study were to evaluate the accuracy and position of the digital surgical guide before and after implant placement with the guided trephine drill. The digital process chain work from Intra oral scan with denture will be performed. And then cone beam computer tomography (CBCT) with gutta-percha marker denture. The virtual prototyping precisions of 5 stereolithographic surgical splints are validate a design before committing to making the rapid prototype were excellent. The satisfaction score compare with the conventional splint and provisional crown improve 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 the 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), for the depth deviation. The results show a statistically significant difference of the implant placed between the conventional and the virtually planed implant positions with the CAD/CAM-guided surgical template.
