A New Transfer Technique (San Technique) of CAD/MAM Surgical Guide for Prosthetic Driven Implant

Statement of problem there is absence of link between virtual implant planning and manually fabricated surgical guides. Purpose to design and evaluate a simple technique (San technique) to manually fabricate cast-based surgical guide derived from virtual computer aided design. Materials and methods Ten partially edentulous patients were selected for this study. The standard radiographic template were fabricated and a reference plate with three radiographic markers where attached to the occlusal surface. CBCT was acquired and virtual implant planning was performed using AccuGuide software. The virtual plan was transferred to the manually fabricated surgical guide using an innovative simple technique (San technique). The implant bed was prepared through the surgical guide utilizing UniGuide surgical kit and Bicon dental implant was installed. Post-operative CBCT was superimposed onto virtual planning to evaluate the transfer accuracy. Data were collected, tabulated and statistically analyzed. Results There was no statistically significant difference between the virtually planned and placed implants using the innovative San technique. The mean global deviation at the coronal level was 0.52 0.19, while at the apical level was 0.84 0.25 and the angular deviation was 5.14 1.31 degrees. Conclusion San technique produced acceptable functioning surgical guides. It represents a reliable convenient alternative to CAD/CAM fabricated surgical guides.
