Digital registration method may be advantageous in accuracy evaluation of implant placement
The majority of previous studies used the radiographic methods to evaluate the accuracy of implant placement [Since the CBCT data was acquired at a voxel resolution of 0.2 mm, it was impossible to achieve superimposition precision better than 0.2 mm using conventional CBCT methods [The accuracy of implant surgery with and without a surgical guide was evaluated by superimposing the implant planning data and postsurgical data by digital registration method in four steps [
