Objective: The optimal positioning of oral implants can improve biomechanical, functional and esthetic results. The purpose of this study was to establish a computer-assisted design system for predictable preoperative planning of dental implant surgery, in order to determine the optimal number and position of dental implants to be inserted. Material and Methods: The developed system was composed of Spiral CT Scanner (GE LightSpeed Ultra), a Intel Pentium IV computer with high-resolution color video card ( ELSA Synergy2000), a high-resolution monitor ( SONY CPD G4420 ) and a laser printer ( HP-1000 ). CISPlan, the interactive software for predictable surgical planning of dental implants placement, developed at the Department of Computer Science and Engineering ( Shanghai Jiaotong University), It is based on GE Advantage Workstation AW4.0, Advantage-Dentascan and ezDICOM. The software was developed using programming Visual C++ 6.0 on the Windows platform.Ten dry human and thirty patients¨?¨˙ maxillas and mandibles were separately scanned using GE CT Scanner. Reformatted images from axial scans were used to analyze the structure of jaw bone and to plan the position of dental implants ( Camlog, ALTATEC, Germany) in each maxilla and mandible, trying to achieve a maximal cortical bone contact. Results: There was no significant difference between two sets of measurements on the same image(P>0.05). The analysis, implant mimicking and appearance prediction in 30 patients with missing teeth have been clinically realized by the developed system based on SCT technique and computerized digital image processing technology. The accuracy of the implant position achieved at the jaw crest satisfies biomechanical, anatomical and esthetic requirements.Conclusions: The developed CISPlan system offered the superior assisted abilities for preoperative surgical planning of dental implant placement, it was quicker, easier, less prone to error, more accuracy of prediction and more likely to be based on the best available data.
