The accuracy of computer-guided implant placement decreases when the remaining teeth are poorly distributed. This clinical report demonstrates a protocol for using a superimposition-anchor microscrew (SAM) system to improve the accuracy of computer-guided implant surgery in a posterior unilateral edentulous area. The SAM functioned as a fiducial marker for image superimposition and as an anchor for guide positioning. Applying the SAM system to computer-guided implant surgery enhances the accuracy of implant placement by minimizing possible errors occurring during image registration and guide positioning.
