A digital process for designing and manufacturing a cobalt-chromium (Co-Cr) surgical template for static computer-aided implant surgery (s-CAIS) is described. The use of Co-Cr provides the advantage of a material with improved mechanical properties to reduce the possibility of surgical template fracture during s-CAIS. The stronger material also allows for a thinner surgical template, which in turn allows better access when the interarch operative space is limited or a longer implant is inserted. Limitations of the technique include the need for computer-aided manufacturing technology and, with the use of Co-Cr, a higher overall cost.
介绍了一种用于设计和制造钴铬（Co-Cr）手术模板的数字化工艺，用于静态计算机辅助种植手术（s-CAIS）。使用 Co-Cr 具有改善机械性能的优势，可以降低 s-CAIS 过程中手术模板断裂的可能性。这种更强韧的材料还可以使手术模板更薄，从而在颌间手术空间有限或插入更长的种植体时，提供更好的操作空间。该技术的局限性包括需要计算机辅助制造技术，并且由于使用了 Co-Cr，整体成本更高。
